Dödshjälp i dagspressen : En analys av dagspressens rapportering om Kims öde
A good flow of information in organizations is one of the key aspects of how we define a well-functioning organization. The information flow could be internal as well as external between actors within as well as outside of the organization. In a logistics organization this flow of information is equally important as in any other kind of organization. In this paper we have explored information flows in logistics organizations by applying, boundary spanning and the mobile-stationary divide perspective. In boundary spanning the main goal is to erase or relocate some of the boundaries within an organization, in our case to make the flow of information internally as well as externally better.
Kväveförluster och energianvändning på mjölkgårdar i västra Sverige :
Protecting the environment has with time grown to take a more central role in the society.
Agriculture plays an important role in the society since this sector produces our food. More
thorough research on how agriculture affects the environment is therefore motivated. This
research can be used to improve the agricultural practice from an environmental point of view.
This is something that both the farmers and the consumers can profit from.
This study aims to form the basis for creating environmental indicators for use of nitrogen and
energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about
their farms, both organic and conventional. They produce milk with different intensity, defined
as the amount of milk delivered (sold) per hectare of arable land.
Twittrande bibliotekarier: informationshantering 2.0?
The present study is embedded in the research field of Personal Information Management (PIM) and its goal is to contribute to this research area by showing information management aspects in untraditional contexts, as in the social networking site Twitter. The aim and purpose of this two year's master thesis was to investigate the beha-viour of librarians within the context of Twitter. The objectives of this thesis focus on the query of the informa-tion management aspect of Twitter, and on the investigation into whether Twitter offers the possibility to reach a state of flow while using it, as well as inquiring into the relationship between Mihaly Csikszentmihalyis flow theory and PIM. The theoretical framework of this thesis is centred upon the flow theory and the conditions that are necessary to reach a state of flow. To fulfill the purpose of this thesis a directed content analysis is applied as an investigative method, where its in-depth research aspects will be applied upon the empirical material, which contains 429 tweets.
Flow i undervisningen - en studie om lärares uppfattning om begreppet flow
Det här arbetet handlar om flow och hur begreppet samverkar med olika aktiviteter i våra liv. Bakgrunden till flow förklaras inledningsvis i kapitlet om teoretisk bakgrund och sätts senare i relation till inre förändring, socialt samspel, fysisk aktivitet, kommunikation, samt pedagogik. Syftet med arbetet är att ge svar på hur flow kan användas i undervisning. Som metod för datainsamling har jag gjort en gruppintervju med fyra lärare aktiva vid Musikhögskolan i Malmö. Gruppintervjun fungerade som ett vardagligt samtal mellan fyra personer och resultatkapitlet är sammanställt i sex rubriker: Introduktion; Personernas uppfattning om flow; Vägar till flow och hinder på vägen; Gruppflow; Flow, kvalitet och kommunikation; samt flow och undervisning.
En rörig historia : en fallstudie över Secorocs processflöde av DTH-rör
Abstract Title: A messy story ? a case study of Secorocs process flow of DTH-pipes Presentation date: 2010-06-02 Course: Bachelor thesis in businessAuthor: Kristoffer ForsmanAdvisor: Kjell GustafssonKeywords: Management control, process control, lean production, process flow analysisPurpose: The purpose of this bachelor thesis is to develop an overview of the process flow for a specific product, and with the help of this mapping based on a lean production philosophy show possible improvement proposals and how these can lead to a more efficient process flow.Methodology: I have used a case study of Secorocs DTH-pipes and my primary data are gathered through interviews and observations. I have used theoretical framework to establish a process flow analysis. This is to obtain data on process activities and whether they are creating value or not. This leads to a current mapping of the situation in Secoroc on DTH-pipes and then analyzed and suggestions for improvement are developed.Conclusions: That by using the above mentioned mapping of process flow of DTH-pipes, problem areas could be illustrated.
Fordonsgas ur gödsel och vall
AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.
Optimering av indunstningsprocess
The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.
Vårvetesorters effektivitet i användningen av kväve under den huvudsakliga tillväxtperioden
Crop efficiency in utilizing available nutrients is an important factor in increasing produc-tivity and reducing the environmental impact of agriculture. Nitrogen is the nutrient that plants need in the largest quantity and wheat, along with maize and rice, is the world's most cultivated crop. In this work, the Nitrogen Use Efficiency, NUE, during the major growth period, HTP, of twelve different spring wheat varieties, were examined. The NUE was calculated as the product of uptake efficiency of nitrogen, UN, and the conversion effi-ciency of nitrogen to biomass, EN. The purpose of this work was to find if there are varietal differences in NUE and its components among the twelve varieties and to link a high NUE to specific characteristics of the varieties.
Miljödammars funktion som kväve- och fosforfälla samt som bevattningsdamm i Sölvesborgs kommun
A study was made on four environmental ponds in Sölvesborgs municipality. The reason forthis was to see if the ponds had fulfilled some of the questions that was mentioned in theproject ?Rädda Hanöbukten?. The questions were as following; do the environmental pondsdecrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease theuse of groundwater in Sölvesborgs Municipality and are there any restrictions on what thewater in the ponds is allowed to be used for. In order to answer these questions aquestionnaire was made and interviews were held.
Ökat flöde genom timmersorteringen vid Ala sågverk
Ala sawmill in Ljusne, Hälsingland, has increased its flow through the sawing plant during the last couple of years. The problem now is the sorting plant, as this part of the mill is now slower than the rest. A close analysis of the sorting plant was therefore necessary to be able to increase the flow through. The aim of the project was to find solutions that can lessen downtime and increase flow. The goal was to increase the flow from 650 to 925 logs through the sorting plant per hour.
Arbetsglädje : En kvalitativ intervjustudie om hur fem lärare i grundskolans tidigare år beskriver arbetsglädjens betydelse och påverkan
The goal of this study is to examine what five teacher?s impression of the teacher?s role is in their previous years. How important the ?joy at work? is in relation with the educational progress? And what aspects that contributes to the? joy at work? and what obstacles that stops them. The essay will also go through the concepts of a teacher role, with connection to the theoretical perspectives of Csikszentmihalyi?s Flow and Antonovsky?s Salutogenesis (KASAM).The method I used was interviewing five teachers and I used Larsen?s chapter of ?content analysis? as a basis, I also used Flow and KASAM as theoretical references in my analysis.
Finns det något samband mellan stormusslors (unionoida) föryngring och utsläpp i närheten av dess levnadsmiljö? : en jämförelse mellan vattendrag i Västra Götaland
Common species of freshwater mussels may, like the freshwater pearl mussel (Margaritifera margaritifera) have a drastic decline in number and there is several reasons, like sedimentation, a decline of host fishes, introduction of alien species, nutrition leakages from agriculture and pollutants of medic drugs and poison. Ann Gustavsson made in the year of 2007 a study over rejuventation of freshwater great mussels in nine watersystems and considered that the rejuventation within the populations were all along the line poor. This study orients from her work and points to determine if there is a connection between the poor juventation and pollution of nitrogen and phosphorous from industries and private sanitations. The study was performed with the software program ArcGIS9.2 to take out drainage areas for the concerned habitats and contact was made with the concerned authoritys. When it comes to supervision of private sanitations is it the countys and for industries is it the county administrative board.
Kan mjölkkors utnyttjande av vallprotein bli bättre? : utfodringsstrategier och konserveringsmetoder
The purpose with this literature study was to investigate the possibilities for improvement of forage protein in dairy cows with focus on feeding strategies and conservation of forage protein. The utilization of forage protein in dairy cows is often not that efficient as it could be. The feed crude protein consists of both true proteins and non protein nitrogen. The digestion of proteins in the rumen depends on the protein degradation rate and the ability of the microbes to synthesize microbial protein. The microbes need a balance between carbohydrates that provide them with energy and proteins that are degradable in the rumen.
