Sustainable shopping : consumer behavior in purchasing and donating secondhand clothes

Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.

Den villkorliga självkänslans relation till self-efficacy

A self-esteem that is contingent on affirmation from others leaves the individual psychologically vulnerable. Ccontingent self-esteem has been shown to be either relationship or competence based. The aim of the current study was to examine the relationship between relationship based self-esteem, competence based self-esteem, the under dimensions of those, and self-efficacy. Questionnaires were handed out to 69 university students. The results indicated that competence based self-esteem predicted a significantly low self-efficacy.

Bland alphahannar och mjuka män : en studie av jämställdhet inom Polismyndigheten Värmland

Syftet med den här studien är att undersöka hur individer med ledande befattningar inom Polisen Värmland tolkar begreppet jämställdhet. År 2007 firades att kvinnor funnits i tjänst inom Polisen i 50 år. Jämställdhet är numera en norm i samhället (Alvesson och Billing, 1999), och vi ansåg att det skulle vara intressant att undersöka hur polisen förhåller sig till den normen, eftersom det är en traditionellt sett mansdominerad organisation. Som metod har vi valt en kvalitativ ansats eftersom vi vill undersöka förhållningssätten hos de olika individerna, vilket är svårt att utläsa av en kvantitativ metod (Jacobsen, 2002). Vi har valt att intervjua individer med en ledande befattning, eftersom det finns forskning som visar på att ledningens inställningar till jämställdhetsarbete är avgörande (Roth, 2007).

Falu gruva och hållbar utveckling

AbstractFalu Copper Mine and Sustainable DevelopmentKarl-Markus AnsnaesFalu copper mine was Sweden?s oldest mine industry which lasted for almost a thousand years. Throughout the history its area has been vastly contaminated by sulfur oxide. The contaminations has created the mining area to an environmental risk zone which has the ability to spread out into the Falu River. The river has its connections to the Dal River which is discharging towards its mouth in the Baltic Sea.

Lean i arbetsprocessen för projekledning

This report presents the results of a thesis in which the department PL Hus at Grontmij AB isstudied. The study has been done in order to locate problem areas in order to streamline andimprove the quality of working. The study was done by an engineering student from theDepartment of Industrial Management at KTH on behalf of Grontmij AB. The project extendedover a period of 20 weeks during spring 2011.In addition to the Department itself has two project managers in two different projects beenfollowed. The method used has been participant observation and was used to be able to comeclose to reality and thus find problem areas where there are opportunities for development.Validation was made through comments and opinions from workers at Grontmij AB, afterreading the reports analysis.Based on a system and holistic approach has parallels been drawn to the production systems suchas TPS (Toyota Production System) and lean production.

Make not waste: rethink, recycle & redesign

I den här uppsatsen kommer jag berätta om min process att skapa något nytt och unikt av sådant som i vanliga fall anses ha gjort sitt. Syftet med den här processen har varit att vidga mina vyer när det gäller material och deras användningsområden. Att utveckla min egen stil samt inspirera andra att se möjligheter med att återanvända och ta tillvara på sådant som redan finns i vår omgivning. Att kunna se på föremål med nya ögon och placera in dem i nya sammanhang, är något vi alla behöver lära oss mer av. Både för vår egen skull och för vår omgivnings bästa..

Inverkan av torrsubstanshalt och temperatur på kompostens syrabildning :

Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.

Beräkning av värmeförluster och energieffektivisering av elbussar

The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå.                               The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.

Effektivisering av Scuffplatemonteringen på Preciform

Preciform AB är ett legotillverkande företag i Eskilstuna som har specialiserats sig på djupdragning, svetsning, slipning och formning av tunnplåt samt ytbehandling och montering. Företaget har som en del av sin produktion montage av Scuffplate till Volvo XC90-R-design.Från 2012 kommer VCC att ändra utseende på XC90-R-design, vilket innebär för Preciforms del att det blir en förväntad ökning av dagstakten samt att det kommer ställa ökade krav på logistiken runt Scuffplatemonteringen, vilket dagens process inte är anpassad för. Syftet med det här examensarbetet, som är en del av en förstudie på Preciform är att förbättra monteringsprocessen, skapa en överskådlig hantering samt lagerutrymme för ett ökat antal artiklar av ingående material.Tidsstudier av genomloppstid, processtid, godshantering och transporter samt gångstudie genomfördes för att identifiera förbättringsåtgärder, där de olika studierna tjänade som underlag vid beräkningar och jämförelser före och efter implementering av förbättringsåtgärder.Analyser av studierna visade att en av scuffplatemonteringens sex klart avgränsade stationer hade en högre genomloppstid än de andra. Föreslagna förbättringsåtgärder har syftat till att jämna ut takten i monteringsprocessen och reducera waste.En ny layout presenterades och efter viss modifiering implementerades den tillsammans med merparten av förbättringsförslagen.Beräkningar av tillgänglig tid i monteringen visar att en annan arbetsfördelning och indelning av stationer är möjlig i ett fortsatt förbättringsarbete.Jämförelser mellan gammal och ny layout visar på en reduktion av waste i genomloppstiden med 32 procent och en stegreducering med 30 procent.En fortsatt verksamhetsutveckling kommer att reducera tid och steg ytterligare. Resultaten av vidtagna förbättringsåtgärder kan utgöra grunden för en ny förbättringsprocess enligt principerna för Demings hjul.

A comparison of two certification schemes for dairy cow welfare in relation to resource-based, management-based and animal-based measures

Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.

Business Potential of Software Defined Radio Technology

The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.

Stor problematik på liten yta : Att skriva informationsmaterial för skattefinansierade verksamheter

The purpose of this thesis has been about processing an already existing folder for a tax funded organization which is also the employer for this mission ? Expectrum. The reason is that both Expectrum themselves and the recievers of the folder are unhappy with the existing material. The critic that has been directed to Expectrum is that the recievers have trouble understanding what Expectrum is and what they do. Based on qualitative methods such as interviews and text analysis I?ve been able to answer my questions for this thesis.

Produktivitetsstudie Brobyggnad

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..
