Lärande - styrt eller i samspel? : En studie om lärares syn på undervisning och lärande
This study?s purpose was to examine which main forms of teaching methods that occurs in the Swedish nine-year compulsory school and how often learning through social collaboration take place. The study contained literature and interviews with eight teachers. Our research-questions were: What is the teacher?s opinion about different teaching methods, their opinion about learning and teaching and if there were any difference between the teachers teaching younger or older students regarding teaching methods? Our conclusions of this study were that ?lecture-methods? is the most common among teachers.
Ljudlandskapets Attribut: Metoder för att bättre förstå och beskriva ljudlandskap
In soundscape research, the field?s methods can be employed in combination with approaches involving sound quality attributes in order to create a deeper understanding of sound images and soundscapes and how these may be described and designed. The integration of four methods are outlined, two from the soundscape domain and two from the sound engineering domain. This study has shown that by combining these methods the understanding of both the entire soundscape and the specific sounds increase. The study also shows that when the methods are used, there is a qualitative change of the description and understanding of soundscapes and the concrete description becomes more elaborate..
Självstyrande grupper -En organisationslösning för effektivitetsmaximering
The aim of this paper is to investigate to what degree the groups in our inquiry work independently. It is a qualitative research, which points to a well?functioning unit, that by definition is not self-governing, but has many traits of self- government. We have reached to the conclusion, that complete self?government does not have to be the best solution, if you want both quality and efficiency.
Tre lärarperspektiv : En studie om olika arbetsmetoder i förberedelseklass och i ordinarie klass
The Swedish school reflects the society that we have today, a society with many different ethnical and cultural backgrounds. The purpose of this investigation is to study how the school is working with children that recently immigrated to Sweden. What kind of methods are they using at school, to get the best development as possible? Do the teachers manage to be concerned of the students in the school? What kind of reception do these children get in the school? What methods are the teachers using? And are these methods really the best to use to enhance the language and cognitive development of these students?The methods I have been using to examine these questions have been qualitative. I have interviewed three teachers about their everyday work in a multiethnic school south of Stockholm.
Övervikts påverkan på kundmötet
The use of thin and attractive models to promote companies' products is widespread among marketers. This is true even for companies whose products have little or no association with beauty or body weight. As the proportion of overweight people continues to grow in many developed countries the ideals used by marketers to attract customers strays further away from the actual attributes of the customers themselves. What is little understood is what effect overweight has on the efficiency of the product promoter. Some limited research has studied how the efficiency of the product promoters in printed advertisements is affected by the existence of congruence between the product promoter and the product itself.
Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering
This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.
Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.
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..
Effektivitet i grundskolan - en studie om Leans applicerbarhet på processen utvecklingssamtal
Efficiency has become an important objective for many providers of welfare services. Among Swedish schools, both private and public, increased administrative demands seemingly influence operations, and affect teachers negatively through perceived stress. Simultaneously, Swedish students scored an all-time low in the latest PISA survey, and are now performing below the OECD-average in science, mathematics and reading. A central administrative task in the Swedish elementary school is the parent-teacher conference, which is an important activity in supporting the development of the student's knowledge and social skills. Lean is a well-established operations framework, which has proven successful in order to improve process efficiency.
Åkertistel : biologi och icke-kemisk bekämpning
A growing problem in Swedish herbicide free agriculture, the Canadian thistle has been the object of several new trials, seeking methods for non-chemical weed control. The new trials have mainly confirmed earlier experiences; that the most successful methods of control are springtime ploughing, repeated cutting and competition from a stout crop. Row hoeing has also been proven effective. As opposed to earlier recommendations, half season fallow has shown to be a risky and often ineffective method of control. Trials regarding biological methods have shown that above others thistle rust (Puccinia punctiformis) may have the potential of controlling Canadian thistle the future.

This is a study in my preparations for my final concert at the Academy of Music and Drama- ?????????? University. My aim is to create a plan and a schedule for my practising methods and other preparations so I will be able to perform at the top of my ability.I have studied and chosen a collection of methods that will help me prepare for my concert and at the same time develop my oboe playing. As a result, I have found an effective way for me to prepare technically on my instrument. I have also learnt and developed methods in how to focus and mentally prepare for a performance..
Ideella organisationer- En arena för diktatur
The purpose of this research was to examine the current field of management in non-profit organizations, mainly focusing on managerial approaches, but also the impact of organizational size on the shaping of governance. Non-profits are widely discussed in contemporary research, particularly due to the increasing external pressure on voluntary organization to professionalize the way they work in line with standards in the private sector. Due to this our thesis aims to investigate whether professional, bureaucratic approaches are useful when governing a non-profit organization, or if social structures are enough to ensure goal congruence and efficiency. To conduct this research qualitative interviews were carried out and a case- study was made, using the Swedish Karate Federation as object of study. Results show that formal and more professional structures are useable to achieve efficiency and prevent inertia within the organization.
Utvärdering av larmsystem för lageroptimering under trendvariation
Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.
Prefabricerade passivhusväggar
Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.
KappAhls sociala ansvar. Hur ser det ut i verkligheten?
With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.
