Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie
The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..
Pedagogers uppfattning om pedagogiskt drama inom förskolans verksamhet
Syftet med denna studie var att undersöka pedagogers uppfattningar om hur de använder vardagliga och icke-planerade samtal för att främja barns språkutveckling, samt vilken potential detta arbete kan ha.Undersökningen utgick ifrån en kvalitativ forskningsmetod i form av intervjuer som genomfördes med sex aktiva förskolepedagoger. De genomförda intervjuerna transkriberades och bearbetades för att kunna sammanställas till ett tydligt resultat.Resultatet av studien har bland annat visat att pedagogerna är väl medvetna om att barn utvecklar sitt språk i samspel och har därför tänkt till angående hur de vill stötta dem i denna utveckling och hur de kan vara en språklig förebild. Pedagogerna skiljer sig i sina beskrivningar av om och hur de använder sig av de vardagliga och icke-planerade samtalen som en språkutvecklande metod i förskolan.En viktig slutsats som dragits av studien är att vissa av pedagogerna är väl medvetna om vad de önskar att uppnå med de vardagliga och icke-planerade samtalen och har tillsammans med sitt arbetslag lyft detta som en medveten metod för språkutveckling, medan andra inte alls lyft det i arbetslaget.Genom denna studie hoppas jag kunna inspirera förskolepedagoger och andra som jobbar med eller på annat sätt samtalar med barn att fånga upp och ta tillvara på de vardagliga och icke-planerade samtalen. De har stor potential ? glöm inte bort att ta vara på dem..
Styrning i en kundinriktad organisation : en studie av en elitidrottsförening
Background: There has been a movement of power towards customers in most markets which puts higher demands upon the customer orientation of organizations to survive competition. In general the opinion is that satisfied customers also are profitable for the organization. Even though a consciousness exists about this connections importance for the organization there exists no prominent economical theory showing how a organization should work with customer adaptation and how management should be shaped for success in this area. In the field of competitive sports clubs a similar trend is discernible since the field is increasingly commercialized.Purpose: The purpose of this study is to adapt The Balanced Scorecard as a model to the demands on management that customer orientation causes and to use the knowledge created during the study to show how customer orientation in a competitive sports club could look.Realization: The study first takes the form of a literature study which emerges into a theoretic development. Above that a case study of Linköpings Hockey Club has been accomplished so that knowledge created from the literature study could be used on competitive sports clubs.

Växter för miljöer där barn leker : en analys med utgångspunkt från Halmstad kommun
Det har gjorts flertalet studier som bekräftat vegetationens betydelse i leksammanhang, men det finns ett behov av vidare studier i enskilda växtval. Denna studie har gjort ett första försök i att bedöma vedartade växters lämplighet för leksammanhang utifrån (A) risk, (B) slittålighet och (C) lek. Studien har gjorts utifrån vegetation i direkt anslutning till ett antal lekplatser i Halmstad kommun.
Lekplatsen som ståndort ställer stora krav på växters tålighet för slitage, och det är därför ett viktigt kriterium i arbetet med att välja lämpliga växter. Risker som bör undvikas i leksammanhang är taggar, tornar och giftiga växtdelar. För bedömning av växters positiva påverkan i leksammanhang studerades växtmaterialet utifrån kriterierna: (1) förekomsten av löst material, (2) barns möjligheter att på olika sätt påverka och använda vegetationen och (3) växters potential till kojverksamhet.
Studien visar att samtliga studerade växter kunde bedömas som slittåliga och att alla växter uppfyllde lekkriteriet löst material.
Välgörenhetsorganisationers marknadsföring : "First they open their hearts, then their minds and then they will open their wallets". (Maud Randel)
Our reason for this study is to research how non- profit organizations focused on fundraising, market themselves to create and keep the relationships with their potential and existing contributors. With this study we also want to create an image of the meaning of marketing, applied to non- profit organizations focused on fundraisings, struggle towards attracting more contributors. We also aim to research what our respondents believe will be the outcomes of marketing on nonprofit organizations in the future. For this essay we have chosen a qualitative method which consists of six interviews with respondents whom have different knowledge and experiences of the non- profit sector. We chose this method to be able to view our main subject from different aspects and through the interviews also form a more profound picture of the non- profit sector and also, finally, se what the respondents think about the issue.
Landscape urbanism : from a methodological perspective and a conceptual framework
Landscape urbanism has for the last decade been a topic for debate among practitioners and theorists involved in forming the contemporary city. The advocates for landscape urbanism mean that traditional dichotomies like city and country are invalid to illustrate the contemporary urban realm. Rather, a new urban morphology has evolved, which calls for new methods and models when approaching the city. Landscape urbanism suggests a revaluation of landscape in order to develop these approaches. This paper sets out to map how this is addressed within landscape urbanism.
Nätaktivism ? Slackers eller individer med möjlighet att påverka sin omgivning?
The aim of this thesis was to look to the organization of people through social media and the Internet. Our study was conducted with a current event in focus. We began our study by examine the protests that had arisen as a result of that the American proposed law called "Stop Online Piracy Act" (SOPA)was presented. With our main focus on SOPA we began to investigate those discussions and debates that during a limited period of time were conducted on a large social news site, Reddit.com, which is a form of social media. We focused on the way that people expressed themselves over social mediawhen it comes to political issues and also whether or not Internet activism can have an effect in the society.
Den Bortglömda Kanalen
The matter of CSR and sustainable products has gained an increased amount of interest in recent years as "green products" are becoming a trend with more "eco"-alternatives in the assortment of many retailers. However, among the increasing number of socially oriented customers, it seems that although they claim an increased demand for these kind of products, its easier to "talk the talk" that to actually "walk the walk". This is due to a discrepancy between attitude and behavior, called the attitude-behavior gap. The purpose of this paper is to examine how to overcome this gap by using three different studies to get a nuanced and reality-based view of the problem. The focus within these different studies is on the potential effects inside the store and how information provided has an effect on perceived credibility and purchase intention.

Bemanningsupproret ___________________________________________________________________________ En kvalitativ intervjustudie om journalisters anställningsotrygghet i bemanningsbranschen
The purpose of this paper is to evaluate the work situation for temporary workers within the field of journalism. During the past decade, influential external forces such as commercialization, new technologies and increased competition have brought great changes within the industry. As a result, employers value flexibility of manpower, not least to reduce cost, where the flexible employee is usually leased by the media company from a manpower company. Today it is a normal practice with manpower companies and this way of hourly paid form of employment. Although the temporary worker can sometimes benefit from this kind of employment, there are also significant setbacks like job insecurity.
