Undressing the moves - an ethnographic study of lap-dancers and lap-dancing club culture

The lap-dancing club phenomenon is relatively new in the UK and as a result, in the last decade, it has aroused much public debate. Despite this, the study of this industry here in the UK has been neglected, with the body of research confined to the U.S and Canada. In spite of gaining some academic attention abroad, the literature, which has emerged from the research, suggests a narrow field of interest, concerned with exploitation, risk and dancer motivation. Further to this, there has also been a tendency to address dancer-customer interaction; the relationship between dancers has been ignored. Finally, the general approach of researchers has been to stress the negative implications of a lap-dancing career on the dancers; reflected in the deviant and implicit anti-sex work/exploitation frameworks which have dominated academic thinking in this field of study. Through the use of ethnographic methods the research on which this thesis is based redresses these issues. The data for this research was generated in a UK lap-dancing club using extensive participant observation, estimated at over 2000 hours, along with in-depth interviews to supplement the core findings. The main focus of study was on the relationships between dancers and the culture with which they mutually engage. Through this exploration, some of the key areas of academic interest including dancer motivation, risk and exploitation were directly or implicitly challenged. Further to this, through delving into the relationship between dancers, an understanding of the way in which these relationships are used to cultivate and reinforce dancer status roles in the club was developed. In relation to this, a dancer hierarchy has been identified, comprising of three stages: new girl, transition and old school. Finally, the lap-dancing club culture, which is not only signified by some of the duties of the job, but also by the „social‟ and „emotional‟ rituals with which dancers mutually engage, is also addressed. Although the negative implications of lap-dancing club culture are acknowledged, the social fulfilment and subcultural attachment dancers have to their occupation is also emphasised. This research therefore starts to shift our understanding of the lap-dancing club phenomenon and reconstruct it within a UK context.EThOS - Electronic Theses Online ServiceEconomic and Social Research CouncilGBUnited Kingdo

How does a financial crash affect the Phillips curve?

This study investigates if there is a significant Phillips curve correlation and if the tradeoff changed during the financial crisis of 2008 in countries such as Sweden, Austria and Belgium. It tries to find the evidence for a change in the tradeoff using a time series regression model. The study will first go through the different modifications that has been done to the Phillips curve and how the theory has evolved since it was originally theorized. After that the data that was used in the regression is examined and evaluated. The regression on the Phillips curve that follows is done in two ways, first on a Phillips curve with backward-looking inflation expectations and then a regression with anchored inflation expectations. The results are ambiguous since the regression only found significance for a tradeoff in the Phillips curve with the anchored inflation expectations and not for the backward-looking inflation expectations model which is the more conventional model to use. If we follow the model with the anchored expectations we can see that the tradeoff does exist and that it was strengthened by the financial crash of 2008 in Belgium and Austria. In Sweden however, the only results the regression provided is that a significant Phillips curve correlation is present in the economy

District Heating and CHP : Local Possibilities for Global Climate Change Mitigation

Global warming, in combination with increasing energy demand and higher energy prices, makes it necessary to change the energy use. To secure the energy supply and to develop sustainable societies, construction of energy-efficient systems is at the same time most vital. The aim of this thesis is therefore to identify how a local energy company, producing district heating (DH), district cooling (DC) and electricity in combined heat and power (CHP) plants, can contribute to resource-efficient energy systems and cost-effective reductions of global carbon dioxide (CO2) emissions, along with its customers. Analyses have been performed on how a local energy company can optimise their DH and DC production and what supply-side and demand-side measures can lead to energy-efficient systems in combination with economic and climate change benefits. The energy company in focus is located in Linköping, Sweden. Optimisation models, such as MODEST and reMIND, have been used for analysing the energy systems. Scenario and sensitivity analyses have also been performed for evaluation of the robustness of the energy systems studied. For all analyses a European energy system perspective was applied, where a fully deregulated European electricity market with no bottlenecks or other system failures was assumed. In this thesis it is concluded that of the DH-supply technologies studied, the biomass gasification applications and the natural gas combined cycle (NGCC) CHP are the technologies with the largest global CO2 reduction potential, while the biomass-fuelled plant that only produces heat is the investment with the smallest global CO2 reduction and savings potential. However, the global CO2 reduction potential for the biomass integrated gasification combined cycle (BIGCC) CHP and NGCC CHP, the two technologies with highest electricity efficiencies, is highly dependent on the assumptions made about marginal European electricity production. Regarding the effect on the DH system cost the gasification application integrated with production of renewable biofuels (SNG) for the transport sector is the investment option with the largest savings potential for lower electricity prices, while with increasing electricity prices the BIGCC and NGCC CHP plants are the most cost-effective investment options. The economic outcome for biomass gasification applications is, however, dependent on the level of policy instruments for biofuels and renewable electricity. Moreover, it was shown that the tradable green certificates for renewable electricity can, when applied to DH systems, contribute to investments that will not fully utilise the DH systems’ potential for global CO2 emissions reductions. Also illustrated is that conversion of industrial processes, utilising electricity and fossil fuels, to DH and DC can contribute to energy savings. Since DH is mainly used for space heating, the heat demand for DH systems is strongly outdoor temperature-dependent. By converting industrial processes, where the heat demand is often dependent on process hours instead of outdoor temperature, the heat loads in DH systems can become more evenly distributed over the year, with increased base-load heat demand and increased electricity generation in CHP plants as an outcome. This extra electricity production, in combination with the freed electricity when converting electricity-using processes to DH, can replace marginal electricity production in the European electricity market, resulting in reduced global CO2 emissions. Demonstrated in this thesis is that the local energy company, along with its customers, can contribute to reaching the European Union’s targets of reducing energy use and decreasing CO2 emissions. This can be achieved in a manner that is cost-effective to both the local energy company and the customers.Den globala uppvärmningen i kombination med ett ökat energibehov och stigande energipriser gör det nödvändigt att förändra energianvändningen. Energieffektiva system är samtidigt en förutsättning för att kunna säkra energitillförseln och utveckla hållbara samhällen. Fjärrvärme har en viktig roll att fylla i den här omställningen. I fjärrvärmesystemen kan värmeresurser som annars kan vara svåra att nyttiggöras, som till exempel spillvärme och förbränning av avfall tas tillvara. Fjärrvärme kan även bidra till elproduktion i kraftvärmeverk där totalverkningsgraden är högre än vid separat el- respektive värmeproduktion. En omställning av energisystemet till en ökad användning av fjärrvärme och minskad användning av el genom effektiviseringar och konverteringar från olja och el till fjärrvärme kan bidra till att skapa energieffektiva system. Syftet med den här avhandlingen är att identifiera hur ett lokalt energibolag som producerar fjärrvärme, fjärrkyla och el i kraftvärmeverk kan bidra till att skapa energieffektiva system och kostnadseffektiva globala koldioxidreduktioner tillsammans med sina kunder. Det energibolag som framförallt har studerats i den här avhandlingen är Tekniska Verken i Linköping AB. För att optimera energibolagets fjärrvärme- och fjärrkylaproduktion har energisystemanalyser genomförts, där både åtgärder på tillförsel- och användarsidan har studerats. Genom att se energiförsörjningen ur ett systemperspektiv kan man undvika att ekonomiska och miljömässiga vinster vid en anläggning ersätts av förluster någon annanstans. Optimeringsmodeller, som MODEST och reMIND, har använts för energisystemanalyserna där även scenarier och känslighetsanalyser har inkluderats. För alla energisystemanalyser har ett europeiskt energisystemperspektiv använts där en totalt avreglerad europeisk elmarknad utan flaskhalsar eller andra systemfel antagits. Slutsatser från analyserna är att det lokala energibolaget kan bidra till kostnadseffektiva globala koldioxidreduktioner genom ett effektivt nyttjande av bränslen i kraftvärmeanläggningar och i bioraffinaderier. Speciellt kraftvärmeanläggningar med hög elverkningsgrad, som t.ex. biomasseförgasning- och naturgaskombianläggningar, har en betydande global koldioxidreduktionspotential. Även biomasseförgasningsanläggningar som är integrerade med produktion av förnybara drivmedel för transportsektorn har visat sig kostnadseffektiva med stor potential att reducera de globala koldioxidutsläppen. Styrmedel har dock en stor påverkan på det ekonomiska utfallet för förgasningsanläggningarna. Dessutom har studierna visat att energibesparingar kan åstadkommas genom att konvertera el och fossilbränsledrivna industriella processer till fjärrvärme och fjärrkyla. Eftersom fjärrvärme framförallt används för lokaluppvärmning är värmelasten i fjärrvärmesystem säsongsbetonad. Genom att konvertera industriella processer som inte är utetemperaturberoende till fjärrvärme kan fjärrvärmelasten bli mindre säsongsbetonad och mer jämt fördelad över året. En jämt fördelad värmelast är fördelaktig för driften av fjärrvärmeanläggningar och kan bidra till mer elproduktion i kraftvärmeanläggningar. Den extra elproduktionen, tillsammans med den el som blivit tillgänglig efter konvertering av eldrivna processer till fjärrvärme, kan ersätta europeisk marginalelsproduktion vilket kan reducera de globala koldioxidutsläppen. Det som har framkommit av dessa studier är att det lokala energibolaget, tillsammans med sina kunder, kan bidra till att uppfylla de mål den Europeiska Unionen har angående reduktionen av energianvändningen och koldioxidutsläppen. Dessutom kan detta ske på ett kostnadseffektivt sätt för både energibolaget och dess kunder

National energy policies: Obstructing the reduction of global CO2 emissions? An analysis of Swedish energy policies for the district heating sector

The effect of national energy policies on a local Swedish district heating (DH) system has been studied, regarding the profitability of new investments and the potential for climate change mitigation. The DH system has been optimised regarding three investments: biomass-fuelled CHP (bio CHP), natural gas-fuelled combined cycle CHP (NGCC CHP) and biomass-fuelled heat-only boiler (bio HOB) in two scenarios (with or without national taxes and policy instruments). In both scenarios EU's tradable CO2 emission permits are included. Results from the study show that when national policies are included, the most cost-effective investment option is the bio CHP technology. However, when national taxes and policy instruments are excluded, the DH system containing the NGCC CHP plant has 30% lower system cost than the bio CHP system. Regardless of the scenario and when coal condensing is considered as marginal electricity production, the NGCC CHP has the largest global CO2 reduction potential, about 300 ktonne CO2. However, the CO2 reduction potential is highly dependent on the marginal electricity production. Demonstrated here is that national policies such as tradable green certificates can, when applied to DH systems, contribute to investments that will not fully utilise the DH systems' potential for global CO2 emissions reductions.Energy policies Carbon dioxide emissions District heating

Energy policies affecting biomass gasification applications in district heating systems

Biomass gasification is considered a key technology in reaching targets for renewable energy and CO2 emissions reduction. This study evaluates policy instruments affecting the profitability of biomass gasification applications integrated in a Swedish district heating (DH) system for the medium-term future (around year 2025). Two gasification applications are included: co-production of SNG (synthetic natural gas) for use as transportation fuel and DH heat in a biorefinery, and BIGCC CHP (biomass integrated gasification combined cycle, combined heat and power). Using an optimisation model the level of policy support necessary to make biofuel production competitive to electricity generation, and the level of tradable green electricity certificates necessary to make gasification based electricity generation competitive to conventional steam cycle technology, are identified. The results show that in order for investment in SNG production to be competitive to investment in electricity production in the DH system, support policies promoting biofuels in the range of 16-22 EUR/MWh are needed. For investment in BIGCC CHP to be competitive to investment in conventional steam cycle CHP tradable green electricity certificates in the range of 4-15 EUR/MWh are necessary. The necessary policy support levels are very sensitive to variations in investment costs. It is concluded that the large capital commitment and strong dependency on policy tools makes it necessary that DH suppliers believe in the long-sightedness of future policy tools, in order for investments in large-scale biomass gasification in DH systems to be realised
