Ämnesordsindexering av ryttmästare John Andréns specialsamling : Utveckling av en indexeringsmodell utifrån teoretiska och praktiska perspektiv
This is an explorative study about subject indexing of a special collection of books, administered by the John Andrén Foundation at the library of Ystad. The study summarises a number of theoretical perspectives as well as some practical instructions on how to carry out the task. Theories have been placed into five different groups according to their various approaches to subject indexing. These have been analysed in regard to their usefulness to the Andrén collection. The authors have tested and evaluated six practical models on a selection of books from the Andrén collection.
En utvärderingsmodell för testverktyg : Med inriktning på automatiserade högnivåtester
Testing has always been an important task in the scope of software quality. Though it has never been as much appreciated within the management of the organisations as the software development has. However testing is becoming more attractive within organisations because it becomes more evident how much money working systems saves in contrast to defect ones. A tester often use testing tools to simplify the work progress. There are a lot of tools nowadays but not many evaluating models which helps the tester to know which one to recommend.
Empirisk studie av den radiella förspänningskraftens variation i klassiska skärskruvförband
In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.
Kunskap om marknaden : Besöksattraktioners vikt och dess relation till turistmålgrupp och resesyfte
The name of the study means ?The short arm - a study in diversity and arm?s length in the cultural collaboration model?. Right now there is a reform in the Swedish cultural administration where the responsibility for handing out state funds and grants to cultural organizations is changing from the state government to the local regional governments. The purpose of this study is to map the organisational changes caused by the reform and investigate how this affects the regional policies concerning cultural diversity and the arm?s length principle.
Barns upplevelse av astma : en litteraturstudie
Asthma is one of the most common diseases among children. The aim of this study was, through a literature review, describing children's experience of living with asthma and show how negative experiences can be turned into positive ones, by the nurse's work. Results showed that many of the children with asthma experienced respiratory- and chestproblems, tiredness, panic, fear, anger, frustration, discomfort, irritation and anxiety. Children felt most restricted in physical activity's. Education used to enhance children's experiences included relaxation, imaginary exercises and confidence training.
Deltagande i förändring : en förklaringsmodell av motivationsfaktorer till deltagande i förändringsarbete.
Hospital Mergers have been proved to be troublesome, the most crucial ingredient is believed tobe the participation of members of the organization on all levels. When the hospital mergerbetween the hospital of Malmö and the hospital of Lund is a fact, it seems clear that knowledgeabout managing motivation is important. The knowledge could also lead to increased possibilitiesto improve support for motivation where needed at the hospital.I have through a literature review created a descriptive model of the theoretical view onmotivational factors for participation in change and their relationships. The theoretical modelwhere then tested in a empirical study in which additional data created a more true model of themotivation on participation at the hospital.The findings of the study show how the descriptive model illustrates how the twodifferent departments both work with a empowering philosophy that have built in properties thatenable the employees to gain more motivation. The model also underline the importance of thecommunication role to enlighten the employee in what, where, when and why the change takesplace.
Utveckling och lärande genom fri lek i förskolan
Studies among parents of children with disabilities have shown that they experience a higher level of parenting stress as well as a lower degree of wellbeing, compared to parents of children without disabilities. However, there is a need to further explore parents? experience on this matter within a Swedish context. The aim of the current study was to examine how parents of preschool children, with and without disabilities, in Västerbotten, experience the impact of their child. A sample of 67 parents of children with disabilities and 134 parents of children without disabilities took part in the questionnaire study.
Skador hos betongöverbyggnader för spårväg
This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.
Real Optionsanalys - En fallstudie på SCA Packaging
Syftet med uppsatsen är att identifiera och värdera eventuell flexibilitet i en traditionell investering med hjälp av Real Options Analys. Traditionella statiska investeringsverktyg tenderar att undervärdera projekt. Ett verktyg har senare utvecklats för att kunna värdera osäkerhet och flexibilitet, ofta inneboende i projekt. Uppsatsen är en fallstudie på SCA Packaging och utgår från en deduktiv ansats där data har inhämtats via personliga intervjuer. Historisk analys av de variabler som har störst påverkan på projektet, genomförs med Monte Carlo simulering.
Sitkagranens potentiella merproduktion jämfört med vanlig gran i Hallands län
Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden.
This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation.
The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.
Beslutsmodell gällande finansieringsform samt intern prissättning av ett företags truckpark
To be competitive in the corporate climate of today it is important to have effective logistic activities. A common resource within the internal logistics is forklift trucks, which are used to lift and transport material. It becomes more and more important to decide whether to buy, lease or rent the forklifts to obtain an optimal economic situation. Many companies have issues with internal pricing. It is difficult to price products and services correctly. It is common to price the overall instead of what it really costs.The purpose of the thesis is to present a model for the acquisition of forklifts for internal logistic operations, regarding financing and internal pricing, to obtain economic effectiveness and an optimal forklift fleet size. The study focused on a specific research question, and for this purpose interviews with experts were held, observations were made and a literature study was done.
Förbättrad Kravhantering med hjälp av Lösningsinriktad Pedagogik
Abstract
The purpose of writing this thesis was to improve methods during requirements
engineering phase. Usercentred system engineering has some problem areas, which
are examined and verified to create a new guideline for developers. This
guideline tends to make requirements engineering more effective and help
developers create more concrete requirements.
It is not uncommon that system development projects ends up with unsatisfied
users or delay in deliveries. The reasons are different kinds of communication
problems between users and developers during verification of requirements.
There is a therapy model, called solution-focused therapy, used in family and
individual therapy. The model focuses on solutions for the future instead of
problems in the past.
Lammproduktionens ekonomiska påverkan av MTR :
The Swedish consumption of lamb a increasing, and today we yearly eat a kilo of lamb per person each year. As a consequence the Swedish degree of self production according to lamb is steadily decreasing, and is today about 39 %.Today Swedish Meats is now cooperating with the Swedish lamb breeders organisation to raise that percentage. At the same time the European Union presents a new agricultural reform, the MTR (Mid Term Review). The shape of this new reform is not yet fully known, but the general policy has been more or less outlined. The new reform is split into three propositions: the farm model, the regional model and the mixed model.

Volatilitetsmodeller - En utvärdering av prestation enligt Model Confidence Set
Syftet med vår uppsats var att med hjälp av Model Confidence Set (MCS) finna de bättre presterande modellerna bland de mest ?kända? och undervisade volatilitetsmodellerna. Vidare har vi även rankat dessa modeller inbördes. Eftersom prognoser om volatiliteten är mycket viktigt vid prissättningen på derivat, i detta fall ett räntederivat, är ämnet ständigt intressant. Med Model Confidence Set fann vi ett set av bättre presterande modeller utifrån vårt urval av ursprungliga modeller.
