Avfallshantering på byggarbetsplatser : Potential för en miljöeffektiv avfallshantering
This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention Reuse Recycling Energy recoveryLandfill The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.
Kreativa tekniker-finns det? Om unga män på tekniskt gymnasium som vågar utmana ingenjörsrollen.
Teknisk gymnasieutbildning har genomgått stora förändringar de senaste åren och nya ämnen har kopplats till teknikområdet. Har det vidare teknikperspektivet också vidgat elevrekryteringen? Manliga elever på två skilda teknikinriktningar, ingenjör och arkitektur, har genom enkäter och intervjuer besvarat frågor som rör deras motiv, intressen och framtidsplaner. Ur ett genusperspektiv behandlas männens upplevelser kring teknik och genus.
Utifrån resultatet har tre elevtyper blivit synliga: teknikern, kreatören och surfaren. Teknikern och kreatören är båda målmedvetna i sina studier och framtida yrkesval.
En holistisk investeringsbank - En fallstudie av fördelarna med att vara involverad i hela M&A-processen
Studies have shown that mergers and acquisitions often fail and that a reason to this might be that investment banks do not take any responsibility for the post merger integration. Despite this there have been no studies of the potential benefits of an investment bank taking a holistic approach to the M&A-process and including post merger integration in its service. This study identifies a couple of investment banks that does this and calls them holistic investment banks. In M&A-theory a successful process is often described according to so called success factors that need to be fulfilled in order to achieve a successful result of the merger or acquisition. The business model and work approach of one holistic investment bank is analyzed in this case study on the base of seven success factors from established theories.
?Jag känner personligen att jag ibland är så mättad av de här berättelserna att jag inte orkar höra ett ord till om våld? ? Hur socialsekreterare upplever och hanterar våldsberättelser
The aim of this study is to investigate and analyze the potential effects on a number of social workers that may arise from listening to stories of domestic violence, and how these social workers deal with the potential effects. The study is based on qualitative interviews with seven social workers that work with domestic violence. The theoretical perspective that we used was the theory of coping. The results of this study have indicated that the respondents have been affected of listening to the stories of domestic violence. Examples of different impacts that the work has had on some of the social workers is that they avoid movies and/or books with elements of violence, they are more aware of the domestic violence in the surroundings and there has also been changes in their cognitive schemas.

Miljöskuld - från teori till praktisk tillämpning
Begreppet miljöskuld utvecklades i början av 1990-talet av Arne Jernelöv och definieras som återställningskostnaden för miljöskador som är tekniskt-ekonomiskt återställbara. I Sverige sker ett arbete med miljöskulder inom både den offentliga och privat sektorn och påverkas bland annat av miljökvalitetsmålet giftfri miljö och lagstiftningen. Inom ett energibolag fanns ett behov av att finna ett arbetssätt för att göra bedömningar av verksamhetens miljöskulder. Syftet med den här studien är att titta på vad begreppet miljöskuld innebär, hur det förhåller sig till hållbar utveckling och hur det praktiskt tillämpas i energibolaget. Studien bygger främst på aktionsforskning och litteraturstudier som kompletterats med ett par intervjuer.
Konsekvenser av ny teknik på en sjukhusmottagning
An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system. One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

Staden - fara eller frihet för kvinnor?
This report studies how the divergence between men and women is manifested in the physical space and how the representation of room recreates this divergence. Spaces are coded and women have traditionally been associated with private space and men with public space, leading to that the home is encoded as female space and public squares as male space. Thereby women lack a natural place in public space. The National Board of Housing, Building and Planning (Boverket) wants to change this situation by enforcing safety-creating measures based on gender equality theories.I have studied what potential risks the project initiated by Boverket as well as discuss the potential problems with representation. Can representation be used without freezing the space? I also search for methods for working with a gender perspective without reproducing gender stereotypes and roles and avoiding encoding the private as female and public as male? Also I use a public seminar with urban planners, artists and architects to retrieve how we work with these issues today.I conclude that city planning needs to incorporate new strategies of thought that does not divide space, e.g.
Folkets park i Lund : sedd ur ett landskapsvetenskapligt perspektiv
Stadsdelen Väster i Lund har dålig tillgång till grönytor och en tydlig avsaknad av ett ordentligt stadsdelscentrum. Här finns dock stadens gamla Folkets park med potential att bli en grön mötesplats. Syftet med detta arbete är att göra en analys av Folkparkens potential och se till hur parken skulle kunna bli en mer attraktiv och funktionell samlingspunkt. Delvis baseras arbetet på empiriskt material i form av observationer och en enkätundersökning för att få fram vad Folkparkens besökare har för vanor och önskningar för området delvis baseras arbetet på kommunala dokument, tidigare inlämnade förslag, en jämförelse med andra fungerande parker och tidigare gjorda arbeten som berör planering av stadsrum vars teorier jag applicerat i mitt arbete. Resultatet av mitt arbete är utformat som en sammanfattning av inhämtat underlag, vilken jag sedan baserar min diskussion på.
Solenergi och värmelagring i kvarteret Lagern
Humanity stands before a huge challenge to lower its emissions of carbon dioxide and its use of energy at the same time as the global population is rising and the developing countries are being industrialized. A lot of newly built buildings are due to this challenge, designed to be more energy efficient but also use renewable energy resources instead of pollutant fossil fuels .Solar energy is one of the purest forms of energy that exists in abundant amounts, which is why it is most likely that it could come to play a major part in the future energy market. The main purpose of this report is to investigate the possibility to implement a sustainable energy system with solar thermal heat and heat storage as main sources of energy in the neighborhood ?kvarteret Lagern?, which is the area where the old football stadium ?Rasunda Stadion? was located. New developments within different heat storage techniques have opened up new approaches to enable buildings an all year round heat supply from solar energy. This report will focus on heat storage in boreholes. At the present here is only a preliminary plan of how the neighborhood is supposed to be designed.
Visuell Radio
Visuell radio eller ljudbildspel i radio är i stort sett ett outforskat område. Att det går att göra visuell eller audiovisuell radio rent praktiskt och tekniskt står klart - publiceringsverktygen och tekniska lösningar finns. Det detta arbete problematiserar och diskuterar är hur visuell radio skulle kunna utformas och gestaltas både utifrån ett produktionsperspektiv och ett mottagarperspektiv. Detta sker genom att titta på mediaföretagens multimediala publiceringar men också genom att förstå hur deras redaktionerna tänker om hur ljud och bild kan samverka. Bland annat intervjuas personer som arbetar på New York Times, Svenska Dagbladet, DuckRabbit och MediaStorm för att få denna inblick.
