En förstudie till kvalitetsutveckling på GD-tryck

The print- and mailroom at Gefle Dagblad (GD-tyck) is handling an increasing amount of commercial jobsalong with the newspaper production. Investments have above all been done in the mailroom to be able tooffer commercial costumers a higher degree of finishing and there are plans to expand further in the commercialmarket. GD-tryck is of the opinion that they need to secure the quality of their production to be ableto do such expansion, which is the reason why a quality system of some kind may be appropriate. Howeverthere are no plans to certify such a quality system according to ISO 9001:2000.In this exam report the present methods of working have been analysed from a quality perspective.Suggestions on how GD-tryck should be working with quality development is presented in the fields whereshortage of quality has been discovered. The suggestions taken together do not form a quality system butcan be looked at as ideas of approach to quality fields that have to be developed if a working quality systemshall be accomplished.Many of the quality fields that have been discussed do not have anything to do with technical qualitydirectly but are in some degree requirements for a working quality system.

Värdegrunden i skolan : En kritisk studie av innehållet och arbetet med skolans värdegrund i en senmodern kontext

The purpose of this study is to investigate the content and work processes regarding the values written in the curriculum for Swedish high schools and compare it with theories regarding the individualized society and political moralism. After the clarification of the content in the values of Swedish high schools and the work processes that are supposed to give students fundamental understanding about them, I analyze and compere it to the theories that are presented in the study. The main questions of the study are the following: What kinds of values are found in the curriculum for Swedish high schools? In general, how do Swedish high schools work with the written values when focus have gone from education and learning to instrumental knowledge, results, abilities and flexibility?The result showed that the content and work processes regarding the values in Swedish high schools are purely instrumental and moralistic. Due to the fact, that the individualized society and the neoliberal ideology do not require reflection and real understanding regarding the values.

Den svenska arbetarrörelsens utmaningar och visioner - En undersökning av synen på kollektivet i LO- Tidningen 1991-2005

In this essay I have studied the Swedish Working Class whose part of LO.Ideological texts in LO- Magazines is used to quote texts by collective orindividual terms. Method and theory material show high level of solidarity andequality while theory shows higher level of individualism and autonomy. Myresearch is closer to Boréus than Blocks. Politics taking under the 1980: s apowerful right turns holding a steady course through my material.The question in the essay is: What vision on the collective shows in theLO- Magazine in a time during individualization? Answer to this question is thatthe collective unofficially through LO: s: staff on central level tries to showstrength and unity with terms like solidarity and equality between the sexes.

Renar och klövvilt på järnvägar : en studie i järnvägars effekter på ren, älg och rådjur i norra och mellersta Sverige under 2005

Roads and railroads have significant impact on the surrounding landscape and the wildlife living in it. This study aims to provide an overview of the effects caused by railways to reindeer, roe deer and moose in Sweden in order to make more detailed assessments within this topic in the future. The method used is a study of literature on the subject and a synthesis of databases with information about wildlife mortalities, traffic intensity and fences in the study area; northern and central Sweden. The databases were used to compile digital maps using ArcGIS. Infrastructure brings change to the surrounding landscape and its function as habitat for wildlife. Railroads cause barrier effects such as fragmentation, wildlife mortality, loss of habitat and loss of connectivity.

Förskollärares syn på Kvalitet i Förskolan

My purpose with this work is to find out how it relates with pre-schoolteatchers view about a quality in comparasion to control document, Lpfö-98, and with factors pre-schoolteatchers consider effects quality in pre-school describe pre-schoolteatchers view on that high quality is in pre- school.The investigation has been done by quality interviews with five pre- schoolteatchers working in pre- school. The results show that they do not make a difference between what are high quality and the factors that affect the possibility of creating high quality. Most important is qualified and engaged educationalist in the pre- school who who shows a good attitude towards the children, and where development and learning is central. The most decisive to a pre- schools quality are the personell who work there. A conditon to achieve high quality in pre- school is a head who knows the pre- school activity and its curriculum, and who takes active part in the activity, invites to discussions and offers pertinent competence development.According to the leading document Lpfö-98 you will achieve high quality by offering children rear and care.

Att tala är silver, men är tiga guld

A crisis situation that has been more commonly occurred in the industry of conveniencegoods lately is the product related crises which thereby has become a challenge for everymarketer to handle. As the negative publicity tend to enlarge the crisis and spread to thecategory as a whole, it's not only important to have a crisis management to handle crisesconcerning the company itself. But also to be ready to make the best out of the situationwhere the company is threatened to get infected by the negative effects caused by acompetitor.When companies get the chance to make a response on the negative publicity on theircompetitor, as well as the category, through media, the question is - shall they act And howshall they act Which response is the most effective to send out to get out of involvement, notget infected by negative spill over's or even - to make the valenced comparison a way togenerate positive effects and gain market share The purpose of this paper is thereby to find the optimal strategy for an organization in theindustry to handle their competitor's crises through a pronouncement in media. Anotherpurpose to address is whether the brand strength is moderating the effects from the differenttypes of responses tested in this study. This purpose aims to find guidelines depending onthese moderating effects.The paper commodiously, strongly supports that there are beneficial effects to be generatedfrom making a response in either positive or negative direction in oppose of actively choosingnot to make a pronouncement at all.

Transfetter från idisslare - och dess inverkan på blodlipidprofilen hos friska män och kvinnor

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Trans fatty acids from ruminants - and its effect on blood lipidprofile in healthy men and womenAuthor: Sophie Berg and Sara KarlssonSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundCardiovascular disease is the most common cause of death in Sweden. It is well known that thereis a link between high consumption of industrial trans fatty acids and cardiovascular disease, buthow natural trans fatty acids affect us remains uncertain.ObjectiveThe purpose of this article is to, based on the currently available scientific evidence, concludewhether an intake of trans fatty acids from ruminants generates an effect on the bloodlipid profile of healthy men and women.Search strategyRCT articles were obtained through searches in databases such as PubMed, The CochraneLibrary, and Scopus. Keywords used were "ruminants" AND "Cholesterol" AND "Trans FattyAcids" and "ruminants" AND "Blood Lipids" AND "Trans Fatty Acids".Selection criteriaInclusion criteria were RCT studies conducted on healthy people who did not receive medicationfor hyperlipidemia. Moreover, the results were to be based on fasting blood samples, where atleast ten hours of fasting preceded the analysis of the blood lipids.Data collection and analysisThe search generated eight studies. These were graded according to SBU:s Granskningsmall förrandomiserad kontrollerad prövning, after which four studies were selected.

Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet

Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

Downside Risk - En studie av riskkompensation på den svenska aktiemarknaden

This paper investigates the compensation for risk in the context of the Swedish stock market with a special focus on downside risk. Using daily market data collected from the A-list of the Stockholm Stock Exchange between the years 1983 and 2005 the purpose is to answer the question whether Swedish investors are compensated for holding stocks with high downside risk, measured as downside beta. Using panel data analysis it is shown, in accordance with most previous evidence in international research, firstly that stocks with high beta values on average experience higher returns than stocks with low beta values, and secondly that stocks with high downside beta values experience higher returns than stocks with high beta values in general. On the other hand, cross-sectional regression methodology using a bivariate regression approach shows that downside beta does not explain excess returns very well. Instead, regression analysis suggest that high upside beta does a much better job in explaining excess return over this time period compared to downside beta.

Biblioteket i lärarutbildningen : intervjuer med 13 blivande samhällskunskapslärare

A qualitative study of high school student teachers' ideas about libraries and school libraries.Interviews have been conducted with future teachers about the library's role in their education,their views on library functions in high school and whether they as teachers will use theschool library. The results show that the students have had some instruction concerninghow to use the library as students, but very little as regards their future teaching. The professorsof teacher education focus on the fact that the library should be used in high schoolteaching, not how to use it. Despite this, the student teachers look very positively upon libraries.Libraries play an important part in their education and they are all sure that they asteachers will use the school library, which includes interacting with the librarian. To them, themost important school library function is to allow pupils to seek information..

Majsensilage i Sverige

Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.
