En studie om förutsättningarna att certifiera sig enligt ISO 14001 är desamma för stora och små företag
As the environmental awarenesshas increasedin recent decadessohas the society?s demand forenvironmentalresponsible companies(Ammenberg, 2004).One way for companies to take responsibility and work with environmental issues is to implement anenvironmental management system(EMS). EMSserves as a tool for companies to systematically work with environmental issues and develop the company's environmental efforts. ISO 14001 is theEMSaccording to whichthat the majority of companies today choose to get certified(Brorson & Almgren, 2007). The introduction and operation of the ISO 14001 requires significant financial and human resources and it can therefore be questioned whether the environmental managementsystem is adaptable forall companysizes.The purpose of this studyis to examine whether EMScan provide environmental and economic benefits for companies of all sizes and ifthe conditions to get certifiedaccordingto ISO 14001 is the same for large and smallcompanies.A literature study was made to collect information on company'simplementation of ISO 14001.
Hur unga flickor i åldrarna 12-19 årpåverkas psykiskt av media, i förhållande till sina kroppar : En litteraturstudie
Inom disciplinen kognitiv ho?rselvetenskap tilla?mpas en integrerad ansats da?r taluppfattning beskrivs ur ba?de ett auditivt bottom-up-perspektiv och ett kognitivt top-down-perspektiv. Studien underso?kte hur taluppfattning varierar med, respektive utan top-down-sto?d och vad de kognitiva fo?rma?gorna uppma?rksamhet, minne och inhiberingsfo?rma?ga hade fo?r inverkan. Taluppfattningsfo?rma?ga utva?rderades med hja?lp av ett Speech-In-Noise-test (SIN-test) som bestod av tre deltest da?r enstaviga ord presenterades i en ofo?rdelaktig miljo? besta?ende av ro?ster som talande i mun pa? varandra.
Kvinnors erfarenheter av amningstidens längd i relation till vårdtidens längd : En retrospektiv studie
Syftet med denna studie var att undersöka nyblivna mödrars uppfattning av amningstidens längd och vårdtidens längd relaterat till bakgrundsvariablerna ålder, utbildning och paritet. Datainsamlingen skedde under hösten 2000 och våren 2001. Insamlat material infördes i det statistiska programmet Stat View. Materialet bearbetades därefter i olika statistiska test som t-test, korrelations test och Chi-två test. Resultatet för den exklusiva amningen visar att kvinnor som är högutbildade och omföderskor ammar längre än de lågutbildade och förstföderskor.
En psykometrisk utvärdering av det arbetspsykologiska testet Predicting Job Performance
Ett psykologiskt test används främst inom utbildningssammanhang och kliniska sammanhang, men även inom rekrytering, urval och organisationsutveckling. Det finns idag ett flertal personlighets- och begåvningstest som mäter olika aspekter som kan vara relevanta för en organisation. Predicting Job Performance, PJP, som har sin utgångspunkt i femfaktormodellen, är utvecklat av Psykologiförlaget AB och består av två delar som mäter olika dimensioner av personlighet och begåvning. I denna studie har psykometriska beräkningar utförts för att utvärdera instrumentets reliabilitet samt validitet, främst genom test-retest-metoden. Undersökningsdeltagare var 49 psykologistudenter vid Stockholms Universitet.

In this thesis I investigate aesthetic preference for picture books among children aged 3?6 as well as criteria for preference among parents. Through my design project: illustration of a picture book, I aim to put my research on preference in the context of illustration and design. By using the design project as an applied method for research I have sought to answer how one as an illustrator can apply knowledge regarding preferences of the target groups when illustrating for picture books. I have primarily based my research within the field of cognitive developmental psychology, with primary focus on stage theory, and the field of literature.
Småhuset ? val av bergvärme, fjärrvärme eller pellets
This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.
Sensory studies of an energy dense drink for elderly people
The average length of life is increasing in the western world, hence the older population is growing. A common health problem among the elderly is malnutrition.
Malnutrition causes decreased body strength and is associated with an amplified risk of infections, depression, fractures and increased mortality. The health
care system is therefore faced with the challenge to prevent malnutrition among the growing population of elderly. This could be done by providing nutritious
foods developed to meet the specific needs of elderly. The overall objective of this project was to test a healthy energy dense drink based on oats targeted for the elderly
consumers as a strategy to prevent malnutrition among elderly.
Annonseringseffekt av nyemissioner - En fallstudie på Stockholmsbörsen
Vi utför en fallstudie där vi studerar 108 annonseringstillfällen av nyemissioner under åren 1993-2001 på företag listade på Stockholmsbörsen. Vi undersöker om det föreligger någon överavkastning kring annonseringsdagen. Den effekt vi eventuellt observerar används sedan som den beroende variabeln i regressionsmodeller där vi försöker ta fram förklarande variabler. Vi utför kompletterande test såsom t-test och stabilitetstest för att öka reliabiliteten av resultaten..
Arbetsmotivationens betydelse för engagemanget i en organisationsförändring
The purpose of this study was to examine the relation between self-determination theory and its three basic needs: competence, autonomy and relatedness, and commitment to change in an organizational change.

Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.
Brucellosis in small ruminants : a seroprevalence study in peri-urban farming around the region of Dushanbe, Tajikistan
The mountainous Central Asian and former Soviet country Tajikistan is the least advantaged country economically among the former Soviet Union states. Approximately 6.5 % of the land is arable in a country where roughly 80 % of the households typically own small numbers of sheep and goats. Management practices and animal husbandry in the villages such as uncontrolled breeding, mixing of animals on pastures favor transmission of infectious diseases.
Brucellosis is a zoonotic bacterial disease caused by Brucella spp. The disease is endemic in Tajikistan. B.
Modellering och styrning av flis till en sulfatkokare
At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.
Diagnostiska test i Biologi för kartläggning av elevers förkunskaper in i gymnasieskolan
Syfte: Syftet med detta examensarbete är att kartlägga förkunskaperna i områdena fotosyntes, biologisk mångfald, växthusgaser, energi och hållbar utveckling, samt evolution och naturligt urval hos gymnasieelever som läser ämnet Biologi 1 på det naturvetenskapliga programmet på en gymnasieskola i västra Götaland. Syftet är också att utvärdera betydelsen av diagnostiska test för dessa elever och deras lärare. Avsikten är även att presentera möjliga förslag till att utnyttja resultaten av dessa test för att på bästa sätt kunna hjälpa de elever som har svårigheter i eller ligger i riskzonen för att ha svårigheter i dessa kunskapsområden i Biologi.
Metod och genomförande: Undersökningen har dels genomförts med en diagnostisk test, dels genom intervjuer av tre lärare på gymnasieskolan. Eleverna har även fått två analysfrågor som berörde deras uppfattningar om användandet av denna test inom ämnet Biologi.
Resultat: Resultatet visar att eleverna har bristande förkunskaper inom områdena fotosyntes och betydelse av växthusgaser. Både elever och intervjuade lärare är positivt inställda till diagnostisk test i Biologi.
