Könskvotering i bolagsstyrelser : Ett instrument för att främja en jämställd arbetsmarknad?
The European Union has been working to promote equality between women and men for a long time. Despite this, Sweden still have a gender segregated labor market where men generally has the leading positions. According to European law the member states shall promote gender equality and to take all appropriate measures. Statutory gender quotas for company boards is one such measure that some of the European member states have implemented in national law. The Swedish law has no provisions governing gender quotas and therefore the purpose of this study is to explain how gender quotas for company boards relate to current law, both of European law and national legislation.
Ersättning av Ringhals 3 med ett biobränslekraftverk
This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.
Att hantera kunskapsuppdraget med eller utan goda förutsättningar? : Hur åtta lärare ser på bedömning i särskolan
Media has the power to influences society. Some call them the third power of a state. Through amongst others, the agenda setting theory and the framing theory, this report seeks to understand how media describes the swine influenza and how it uses its power to influence people to vaccinate. As this report will show, there is no doubt that media has had an impact on the Swedish population of which 60 per cent followed through with the vaccination. Media used an information discourse and attempted to present its articles in an impartial manner and used governmental authorities and experts to support its arguments.
Språk som maktutövningsmedel En studie om försök att rättfärdiga Operation Iraqi Freedom
The purpose of this study is to investigate the way George W. Bush used the language as a means to exercise power in an attempt to justify Operation Iraqi Freedom. The theories used to answer the purpose are discourse analysis and three different moral metaphors that are applied on the data.The collected material for the metaphors is constituted of cognitive linguistic books from prominent linguists, such as George Lakoff, Alan Cruse and William Croft, and the material for the discourse analysis is also collected from prominent discourse analysts such as Michél Foucault and Norman Fairclough. The official White House website provides the material for my data. The scientific method used in this study has been qualitative text analysis where the hermeneutic approach has been an essential part of it.The main question: In what way did George W.
Det är ju samma arbete fast annorlunda : marknadsmekanismers inverkan på hemtjänstpersonalens arbetssituation
Many organizational changes have been accomplished in elder care since the 1980's and many of those have been influenced by market mechanisms. The purpose of this study is to examine how the implementation of these market mechanisms has affected three important aspects in the work situation for personnel. These aspects are, demand, control and support. To attain the purpose of this study, five qualitative interviews with home care personnel have been carried out. The interview material has been analyzed and structured with the help of Karasek and Theorells demand-control-support model.
Undersökning av energibesparande metoder för multiplikator
In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage scaling, should be maximally made use of in order to minimize the power consumption..
Kappa Control with Online Analyzer Using Samples from the Digester's Mid-phase
In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.
Störst går först - Vägen till fördärv eller lyckat förvärv Ekonomistyrningseffekter vid förvärv - En fallstudie av ÅFs förvärv av Energo
This bachelor thesis aims to analyse the effects of changes in management control systems following acquisitions, and deduce whether or not these effects are in line with the acquiring firm's objectives of the acquisition. Through a case study of technician consultant firm Energo, acquired in 2010 by ÅF, the study assumes the perspective of the acquired firm. Data has been collected through in-depth interviews at Energo and ÅF and complemented by internal documents to enrich and validate specific facts and statements. Data was then arranged and analysed through Otley and Fierriera's (2009) framework Performance Management Systems to understand how management control systems were constituted before the acquisition, what changes were made following the acquisition, how this process was accomplished and how it was experienced, in order to come to conclusions about the effects of these changes. The study concludes that the changes in Energo's management control system following the integration with ÅF, had significant effects on the outcome of the acquisition, primarily as it led to a high rate of Energo's employees resigning.
Kontroll för ökad kvalitet - mallar för kontrollplan-PBL, egenkontroll samt riskanalys
There are problems with poor quality, poor scheduling and poor working climate in the Swedish construction industry. Many parts have been involved, trying to solve the problem.This spring a new planning and building-law becomes final. In this law, the requirements set on the controls are greater. Hopefully this will lead to fewer construction errors. The requirements set on the working environment have also increased, forcing consultants and contractors to focus on safe workplaces.For each project requiring a building permit, an inspection plan has to been drawn.
Val av energisystem för en hållbar stadsdel : En fallstudie av Östra Sala backe
Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.
Analys och utveckling av boggi till ramstyrd dumper
Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.
Bulleremissioner från vertikalaxlade vindkraftverk
Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..
Verksamhetsstyrning : en fallstudie av en revisionsbyrås anpassning och förväntningar vid avskaffandet av revisionsplikten
This study examines how a company adapts its operating control when the environmental circumstances are changing. This is a case study with a qualitative approach which is based on interviews. The main purpose is to examine how an accounting firm adjusts its operating control in order to meet the abolishment of the statutory auditing. Another purpose is to describe how the abolishment of the statutory auditing will influence or have influenced the choice of measures in the balanced scorecard. The question this study aims to examine is: How do audit firms adapt its operating control in order to meet changes in the environment? This question lead to a second question which the study also aims to examine and is How is the abolishment of the statutory auditing influencing the accounting firms goals, measures and focus in the balanced scorecard? The conclusion of this study shows that the abolishment of the statutory auditing has had an influence on the balanced scorecard.
Elkvalitéproblem vid varvtalsstyrd motordrift i industrimiljö
Övertoner orsakade av varvtalsstyrda motordrifter ger problem i industrisystem. Syftet med studien är att identifiera problemen och ge rekommendationer för att undvika dem. Studien utfördes som examensjobb på KTH för konsultföretaget Ramböll. En litteraturstudie i ämnet kombinerades med elkvalitémätningar på drifter hos Sandvik Mining.Elkvalitéproblem orsakade av varvtalsstyrda motordrifter kommer till stor del av att frekvensstyrningen ger olinjärt strömuttag som, om nätet inte är tillräckligt starkt, påverkar spänningskvalitén. Problemen kan vara driftstopp, störd utrustning och ökat slitage på utrustning för att nämna några.Denna studie visar att vid ändringar i system innehållande övertoner kan framtida övertonshalter approximeras för vissa fall.
Arbetslöshetens psykologiska inverkan på ungdomar: en jämförelse mellan Sverige och Schweiz
Ungdomsarbetslösheten har ökat på många håll i Europa som en konsekvens av lågkonjunkturen och i januari 2010 låg den i Sverige på 29,1 procent. I Schweiz har ungdomsarbetslösheten, generellt sett, varit jämförelsevis låg och år 2009 låg siffran på 8,2 procent. Examensarbetets syfte var att undersöka vilken psykologisk inverkan arbetslöshet har på arbetslösa ungdomar. En enkätundersökning genomfördes med 74 arbetslösa ungdomar i åldrarna 15 till 24 år i Sverige och Schweiz. Enkäten baserades på locus of control, self-efficacy och lycka/psykologiskt välbefinnande och ungdomarnas syn på framtiden och på livet som helhet utvärderades också.
