Agens i matematikundervisning : En jämförande studie av elevers agens och makt i lärandesituationer där IKT används
The purpose of this study is to investigate how power is distributed in the mathematics classroom and how students achieve agency when ICT (Information and communication technology) is used as a teaching tool. Three learning situations, structured by mathematics, are analysed: in the first situation mathematics is taught in a traditional way, in the second mathematics is taught in interdisciplinary projects, and in the third mathematics is taught using ICT as a pedagogical tool. The theoretical concepts of power and agency are used as analytical tools within a socio-political framework. The concept of power is used to assess the students? ability to influence their learning and degree of inclusion in the three learning situations.
Makten över kommunikationen : en kvalitativ studie av kommunikatörens yrkesroll
The communicator has a professional role which is relatively unspecified and hard to define. To work with communication can mean several different tasks, who also might vary between different types of organizations. The purpose with our study is to clarify the professional title communicator and its meaning. By applying a power perspective on the communicators experienced professional role in meaning to find out who has the power over the communication. Our study is made of qualitative interviews with four professional communicators working in private organizations. We have used semi structured interviews in our study which means that we before we went through with the interviews defined themes which the interviews were built upon.
Plusenergi och dess installationer : Kvarter Trettondagen
The latest thing in the area of environmental building today is energy-plus-house. The idea behind the energy-plus-house is to create a house that produces more energy than it consumes. To accomplish this, the house uses renewable energy, in this particular case solar energy. With the help from a proper construction and thoughtfully projected installations you can achieve a surplus of energy. The surplus energy can then be sold to the surrounding buildings and thereby conduce to a financial profit for the household.
Underlag för BREEAM-certifiering : Kristianstad Nya Galleria
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Effektutveckling i den koncentriska fasen i bänkpress och knäböj
Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.
Multilateral och unilateral säkerhetspolitisk praktik och strategi för hantering av Syrienkonflikten
This security study attempts to explain the dynamics of international conflict management of an intrastate conflict, through a combination of three theoretical frameworks. The conflict in Syria is shown to be managed mainly through strategies using coercive diplomacy, and some main contributions within the research field relating to strategies of coercion are used for guidance, to important factors which could affect coercive international conflict management, as well as to additional theories which could enhance the study?s explanatory power through a combined theoretical framework. The two added theoretical frameworks are Power Balancing and a Multidimensional concept of Power. With the aid of analytical tools derived from this combined framework the conflict management is analysed within both a multilateral and unilateral setting, offering some explanation as to why international conflict management (practiced by UNSC multilaterally and USA unilaterally) has shown so little progress in regard to the conflict, as well as why one significant, though limited, result could be achieved regarding the destruction of the Syrian regime?s chemical weapons arsenal..
Fysiologiska kvaliteter hos manliga tävlingscyklister och effekten av högintensiv intervallträning
Abstract Road cycling is well established and has always been described as a highly endurance sport. To be able to compete in such a demanding sport the physiology of the athletes needs to be greatly developed. This review will focus on high intensity interval training and its impact on the physiological characteristics of competitive road cyclists. The main difference between different levels of competitive road cyclists seems to be the capacity to maintain a high sub maximal power output over a long period of time in order to succeed. High intensity interval training, from 30 seconds to 5 minutes, leads to improved VO2peak, aerobic peak power and time trial performance.
Vindkraftsacceptans i olika etableringsfaser. En jämförelse av acceptansnivån i tre områden inom Mariestads kommun
The purpose of this paper is to contribute to a deeper understanding about the acceptance of wind power. Our basic assumption is that local conditions are important and can explain how the acceptance of change at different stages of establishment. The main purpose is to see if there are differences in the acceptance of wind power in different stages, and examine the factors that influence acceptance. That includes how people in three different areas of study estimates that they value their environment and how it is affected by wind turbines. The project was conducted interdisciplinary geo-targeted and consists of three parts.
Making Money in a Dirty Business
Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters.
The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.
En snäll tantroman gör ingen skada en kritisk studie om skyltning och makt
The purpose of our thesis is to take a closer look at what lies behind the display of fiction in public libraries. Through interviewing ten librarians and analysing their statements, it examines the mechanisms behind the displaying of books. The analysis was conducted through the application of two different theories, one by Aant Elzinga and one by Douglas Raber. Elzingas theory concerns methods of working, while Rabers theory concerns the purpose of public libraries and attitudes towards power. The following conclusions were drawn from analysing the statements.
Vems är makten? : En analys av hur makten i barnlitteraturen förändrats på 35 år
Each year a significant number of children?s books, with a wide range of themes, are being published. The relation between children and adults is a common theme. In this study I have analyzed ten children?s books, five from the 1970?s and five from the 2010?s.
Implementering av en PSS i Trängslets kraftstation
The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.
Transientanalys för Forsmark block 2 och 3 : Studie av hur val av driftpunkt och pumpreglering påverkar torrkokningsgränsvärdet
The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.
Läsinlärning och självförtroende : Hur kan barns självförtroende påverkas vid läsinlärning?
In what French philosopher Gilles Deleuze labelled Control Societies, mechanisms reminiscent of censorship ? that is, restriction of information that administrators of power wish to regulate the spreading of ? are present in the concept of copyright. This kind of censorship has theadvantage of not being scrutinized by public eyes in the way that the work of institutionalized censorship agencies such as the Swedish Statens Biografbyrå was. It is not unlikely that expanded possibilities for punishing anyone who spreads copyrighted material will result in larger and larger areas that may not be accessed, as the avoiding of conflict and repressive actions will emphasize the behaviour to take detours around information that is deemed taboo and therefore suspicious and dangerous.The ACTA trade agreement is one proposed tool for such extended possibilities for punishment. This essay does not however claim that copyright and censorship are the same ? but rather that the institutional execution of power that was previously a matter of state censorship has a lot of similarities with current and prognosticated application of copyright laws by corporations.While claiming to protect the individual, the disciplinary power executed actually aims to protect the one executing it; the purpose of the power structure is to replicate itself..
Robotinteraktion på litet företag : Examensarbete Industriautomation
The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.
