Fruktkvalitet inom äppelodlingen : en studie av och för Äppelriket Österlen
The main purpose of this Master Thesis has been to investigate issues concerning apple fruit quality in orchards of Äppelriket Österlen. The goal has been to develop a document, for future benefit towards growers and company management in the production of high quality apples.In order to investigate main issues of fruit quality, focus has been on statistics concerning apple varieties, age of the apple trees, new planting, orchard size and growers opinions. Nine growers have been interviewed to investigate opinions and contribution of different growing techniques to increased fruit quality.
The investigation showed high age of the trees in production and low rate of planting of new trees. Differences in fruit quality were highest between small orchards. Most growers were satisfied with their fruit quality and with their own measures made to improve it.
Diskrepansen mellan policy och praktik. En kvalitativ intervjustudie om den lagstadgade introduktionsperioden f?r nyanst?llda l?rare
The aim of this study is to examine how the induction period for newly employed upper secondary school teachers is implemented in practice, in relation to the Swedish Education Act and the National Agency for Education?s general guidelines. Although this induction period has been legally mandated since 2010, both previous research and current statistics indicate significant shortcomings or wide variation in its practical execution.
The study is based on a qualitative interview study involving 13 school leaders. The interview responses were analyzed using three complementary theoretical frameworks: Lipsky?s theory of street-level bureaucracy, Meyer and Rowan?s concept of decoupling, and Schein?s model of organizational culture.
BB vård i hemmet efter hemgång direkt från förlossningsenhet
A part of the midwife?s profession is to promote and support breastfeeding. The objective of this study was to describe the perception of the level of support and advice regarding breast-feeding given to women who have received postnatal care at maternity wards, and to present the opinions of the aforementioned women on how this support could be improved.Method: Women who have given birth at Uppsala University Hospital were routinely asked to fill in internet-based questionnaires regarding their views on the care that they have received. In this study, our data consists of the feedback from four questions in these questionnaires regarding breast-feeding. The answers to the closed questions were presented with descriptive statistics and the comments on two open questions have been analysed with content analysis.Results: Out of 622 women who were cared for at the hospital?s maternity ward after giving birth, 83% stated that they were very satisfied or satisfied with the information and support they received about breast-feeding, and 78% expressed the same views regarding the delivery ward.
Silence in mathematics ? A dead end : Knowledge about the importance of communication
Syftet med följande examensarbete är att kartlägga den verbala kommunikationens betydelse för undervisningen i matematik inom de tidigare skolåren. Idag är enskild räkning en vanligt förekommande undervisningsform som möter eleverna i skolan. Undervisningen bedrivs enligt inarbetade rutiner och få ställer sig frågan om detta är rätt väg att gå. En av baksidorna är att eleverna kan isoleras och fastna inom sitt eget tänkande. Matematik är ett språk som bygger på förståelse där ett moment kopplas till nästa.
Utomhusmatematik - varför eller varför inte ? : - ur lärarperspektiv i grundskolans tidigare år
Flera forskningsrapporter visar att utomhusmatematik kan vara en effektiv och kompletterande metod till den traditionella matematikundervisningen. Vår erfarenhet är att utomhusmatematik inte tillämpas i så stor utsträckning i dagens skola. Syftet med studien är att undersöka lärarnas inställning till val av undervisningsmetod i matematik samt att få en ökad inblick i vilka faktorer som påverkar detta val. Frågeställningen som ligger till grund för studien är: Vilka faktorer påverkar om en lärare använder sig av eller inte använder sig av utomhusmatematik i sin undervisning? Internationella studier visar att svenska skolelevers resultat i matematik har försämrats.
En riktig man är modig : En preventionskampanj om den idealiserade mansbilden
Men commit more suicide than women all over the world. They commit more violent crimes and are more inclined to alcohol abuse. There are studies that relate this behaviour to the hegemonic image of masculinity.My work focuses on Switzerland. The suicide rate in Switzerland is worrying, for men between 15 and 44 years suicide is the most common cause of death. There is no national suicide prevention and no information or prevention that highlights the connection bet- ween the hegemonic image of masculinity and the suicide rates.
Lönsamhetsanalys av tekniker för utökad elproduktion i kraftvärme : Med hänsyn till elprisets variationer
This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.
Kommunikationens roll i matematikundervisningen : en studie ur ett lärarperspektiv
Det socialkonstruktivistiska synsättet på lärande och vikten av samspel och kommunikation som ett medel för lärande är idag mycket aktuellt. Det framhålls av både forskare inom pedagogik och i läroplaner. Följande studie har behandlat undervisningen i ämnet matematik, med utgångspunkt i hur kommunikation används som ett lärandeverktyg. Teorier om att kunskap är något som överförs till eleverna, traditionell förmedlingspedagogik, eller att det byggs upp främst genom enskild aktivitet, konstruktivism, får idag mindre intresse. Därför är det intressant att ta reda på i vilken grad dessa utgör en del av matematikundervisningen.
Arbetet med jämställdhetsintegrering : En fråga om samordning inom Stockholms läns kommuner
The main strategy of gender equality policies has since the 1990s been gender mainstreaming. Many government inquiries show how much the Swedish government, provincial governments and municipalities are working with gender mainstreaming. The purpose of this paper is to investigative how the municipalities within the county of Stockholm handle gender mainstreaming demands in relation to other demands that the municipalities face. This is in order to closer investigate the hidden factors that create barriers to gender mainstreaming efforts. Given the study's purpose and the formulation of research question, qualitative method is the most suitable method to fulfill the purpose.
Förnuft och känsla : En studie av kokböckers visuella kommunikation under det tidiga 90-talet och sena 00-talet
The interest for food and cooking has probably never engaged the people of Sweden as much as it does today. Especially cookbooks are selling better than ever which has been a quite constant trend since the mid 90's. This study explores the connection between visual communication in Swedish cookbooks and the post-modern values which have influenced the market climate and the visual culture. I have used a theoretical framework as reference consisting of theories of semiotics, visual rhetoric, marketing communications and postmodernism. I have been studying six cookbooks, three from the late 00's and three from the early 90's, from the two separate angles of their graphic design and photographic material.
Attityder mot hemlösa och tron på en rättvis värld : En kvantitativ jämförandestudie bland blivande socialpsykologer
Syftet med denna uppsats var att göra en jämförelse mellan studenter som läser det första respektive det sista året på socialpsykologiskt program på högskolan i Skövde ideras attityder mot hemlösa och tro på att världen är rättvis. Ett ytterligare syfte var att ta reda på om det fanns ett samband mellan attityder mot hemlösa och tro på att världen är rättvis. Den teoretiska utgångspunkten i uppsatsen var perspektivet socialkognition, med relevanta begrepp som attityder, stereotyper och fördomar samt Lerner´s teori (1980) om tron på en rättvis värld. Metoden som användes var kvantitativ och utfördes genom två enkäter; Attitudes Toward Homelessness Inventory (Kingree & Daves, 1997) och The Global Belief in a Just World Scale (Lipkus, 1991). Den statistiska bearbetningen skedde med hjälp av statistikdataverktyget PASW Statistics 17.
"Det är inte bara folkvalda politiker som utövar offentlig makt" : En jämförande studie gällande främjande av integration i fem kommuner i Stockholms län
Based on different integration policies, we aim to examine how five municipalities in Stockholm County are working to promote integration at a local level with focus on voter participation and to some extent, representativeness among foreign-born. Statistics provided by SCB shows that foreign-born tends to vote to a lesser extent than those born in Sweden. Further, we aim to examine the implementation of two policy documents established at a national level concerning integration in contrast to policy documents established at a local level in each different municipality. Further, we aim to examine summaries of actions taken in response to the local integration programs, as well as personal interviews. Each municipality will be considered separately, but we thus seek to make a comparative study.

Thepresent narcotic policy has been questioned due to this increase. As a social worker you meetdrug users on a daily basis.
Medicinska elektroniska tidskrifter hur har forskningsbibliotekariens arbetssätt påverkats?
The aim of this study is to describe how Swedish research librarians feel that their work has been affected by electronic journals. The study focuses on medical electronic journals accessed through consortia agreements via Bibsam, the Royal Librarys Department for National Co-ordination and Development. This thesis includes two main parts: a literature survey and an empirical study. The literature survey shows that since the 1990´s most research libraries are hybrid libraries including both printed and electronic information sources and that librarians tasks to seek and organize information have remained but the tools have changed. Qualitative interviews were performed with four librarians at two university libraries and one university college library on how their work with electronic journals differed from their work with printed journals, which new tasks the electronic journals have brought and which have disappeared and how the librarians professional role has been affected.
Hur har IAS 38 påverkat stora och små företags redovisning? : En undersökning om skillnader mellan stora och små företags nyckeltal
AbstractTitle: How has IAS 38 affected accounting in small and large companies?A study of the differences in the accounting of financial ratios between small and large companies.Authors: Jasmine Choudrey & Rana QadriMain Course: Business EconomicsThe aim of this study is to make a comparative examination between small and large companies in Sweden and to analyse how accounting of intangible assets has been affected or changed due to the introduction of the new accounting recommendations and IAS 38.Main theory: There are no theories available on these type of researches due to the fact that the introduction of the IFRS is relatively new. Instead the essay discusses facts about the financial ratios and IFRS as a starting point for the study.Method: The examination will be a combination of both quantitative and qualitative techniques. The quantitative part will be based on statistics and financial ratios from the different companies annual reports. These financial ratios will be analyzed by performing a confidence interval.
