<p>Safety analysis is a process involving several techniques.The purpose of this thesis is to test and develop methodssuitable for the safety analysis of railway risks and railwaysafety measures. Safety analysis is a process comprisingproblem identification, risk estimation, valuation of safetyand economic analysis. The main steps are described in separatechapters, each of which includes a discussion of the methodsand a review of previous research, followed by the contributionof this author. Although the safety analysis proceduredescribed can be used for analysing railway safety, it has suchgeneral foundations that it can be used wherever safety isimportant and wherever safety measures are evaluated. Itcombines cost benefit analysis with criteria for thedistribution and the absolute levels of risk.</p><p>Risks are estimated with both statistical and risk analysismethods. Historical data on railway accidents are analysed andstatistical models fitted to describe trends in accident ratesand consequences. A risk analysis model is developed usingfault tree and event tree techniques, together with Monte Carlosimulation, to calculate risks for passenger train derailments.The results are compared with the statistical analysis ofhistorical data.</p><p>People's valuation of safety in different contexts isanalysed, with relative values estimated in awillingness-to-pay study. A combination of focus groups andindividual questionnaires is used. Two different methods areused to estimate the value of safety and the results arecompared. Comparisons are also made with other studies.</p><p>Different approaches for safety analysis and methods foreconomic analysis of safety are reviewed. Cost-benefit analysisas a decision criterion is discussed and a study on theeconomic effectsof a traffic control system is presented.</p><p>There are several results of the work. Historical data showsa decrease in the accident rate. The average consequence ofeach accident has not changed over time. The risk analysismodel produces comparable results and enables analysis ofvarious safety measures. The valuation study shows that peopleprefer the prevention of small-scale accidents over theprevention of larger, catastrophic accidents. There are onlysmall differences in the valuation of safety in differentcontexts.</p>

Concerns regarding energy security, resource sustainability, and environmental protection have heightened interests in renewable fuels and sparked the research and development of ethanol as a transportation fuel. This study examines consumers’ willingness to pay for ethanol from various potential feedstocks; corn, switchgrass and wood wastes. Data was collected via a survey of fuel consumers across the United States in 2009. Results show that consumers have a preference for E85 (a fuel blend with 85 percent ethanol and 15 percent gasoline) from corn, switchgrass and wood wastes compared to E0 (gasoline) and a preference for E85 from switchgrass and wood wastes, but not corn when compared to E10 (10 percent ethanol and 90 percent gasoline). Also, consumers have a preference for E85 compared to E10 but not compared to E0. Mean WTP for E85 was insignificant across all models, but significant for all other product attributes; percentage of fuel imported, percentage of greenhouse gas emissions reduced, and the proximity of fuel in driving distance. This suggests a WTP for a combination of fuel attributes associated with ethanol rather than just for E85. Results suggest that price and proximity of the fuel have a greater impact on fuel selection than percentage of the fuel imported and reductions in greenhouse gas emissions. Republicans had a positive WTP for E85 compared to E10 and a negative WTP for E85 compared to E0 regardless of feedstock, which may suggest that Republicans actually have no preference for E85; however, these findings may also suggest that Republicans view E85 as a voluntary “policy” whereas E10 is an example of government intrusion in the free market. Thus, they may ultimately have preferences over the manner in which the blend is being introduced to the market. Across all models, those undecided in political affiliation, those previously familiar with ethanol, and those who prefer to devote U.S. farmland to food instead of fuel generally exhibited a lower WTP for E85 while Westerners, those worried about the environment, and those believe that reducing dependence on foreign oil is more important than environmental protection generally had a greater WTP for E85.

My thesis explores what I call the "Sopranos Experience," which draws upon both the historical conventions of the gangster genre as well as the aesthetics and economics of pay-cable television to complicate The Sopranos' (HBO, 1999-2007) psychological relationship with the 21st-century, neoliberal American audience. The Sopranos Experience explicates how wavering identifications and dis-identifications that develop for the spectator through the series' form and content draw the responsibility of an audience away from moral ultimatums that attempt to finalize their experience with the genre, and towards a more personal ethical entanglement with the characters and their socioeconomic anxieties and desires. The ethical entanglement highlighted by The Sopranos reveals an entanglement that has always existed for the gangster genre throughout its history that has been recognized, but not thoroughly explored by previous gangster scholarship. Because of the The Sopranos' psychotherapy story arc through Tony's (James Gandolfini) relationship with Dr. Melfi (Lorraine Bracco), psychoanalysis plays a key role in the Sopranos Experience. The serial form and narrowcasting develop a more in-depth psychological relationship between the spectator and the characters than seen in previous gangster genre films. Through the psychoanalytic theory of Jean Laplanche, I argue the spectator's closer relationship with the series not only results in the spectator's constitution of self through the fictional characters, but that this constitution of self extends into their lived, everyday experiences with others. In this discussion of the psychological connection between the spectator and the characters, their shared anxieties about and desires for socioeconomic stability in a neoliberal environment mobilizes the spectator's relationship not just with the series, but with others in their lives. In recognizing their atomized role in the viewership experience, The Sopranos allows the spectator to make ethical demands about their atomization and vulnerability in a neoliberal society. Because they can recognize the collective's similar situation, the spectator is situated to make larger demands about socioeconomic systems that atomize the individual.

Pharmaceutical manufacturers’ use of prescription brand-name drugs coupons and vouchers to subsidize patients’ cost-sharing obligations such as co-pays has increased. The co-pays are used by managed care organizations (MCOs) to give their plan members an appreciation of drug costs as well as to offer incentives to use available equivalent generic alternatives due to lower co-pays. With higher tiered co-pays for brand-name drugs being offset by coupons, little is known about MCO representatives’ perceptions about use of co-pay subsidy coupons for brand-name prescription drugs. The objective of this study was to assess health plan managers and pharmacy benefit managers (PBMs) perceptions on the use of prescription drug co-pay subsidy coupons. An online survey instrument was used to collect data. A convenience sample of 834 MCO representatives was selected from the Academy of Managed Care Pharmacy (AMCP) membership directory. A total of 122 surveys were returned of which 105 were usable surveys, giving a response rate of 13.7%. A five-point, 11-item Likert scale ranging from 1 through 5, (1 = ‘Strong Disagree’ and 5 = ‘Strongly Agree’) was used to measure respondents’perceptions. Some items referred to coupons used to get co-pay discounts repeatedly over a year (i.e., long-term use coupons) while some items referred to coupons distributed for trial purposes (i.e., short-term use coupons). Of the 105 respondents, 42 (40%) “agreed,” while 58 (55.2%) “strongly agreed” that co-pay subsidy coupons encouraged non-preferred brand-name drugs over preferred brand-name drugs. A total of 78 respondents (74.3%) reported that brand-name drug coupons undermined tiered formulary structure. Sixty respondents (57.1%) “strongly agreed” that short-term use coupons increased plan sponsor’s costs and 72 respondents (68.6%) “agreed” that sponsor cost increased with long-term use coupons. A total of 42 (40%) reported to “strongly agree” that short-term use coupons should be eliminated whereas 49 (46.7%) respondents reported “strongly agreed” that long-term use coupons should be eliminated. In summary, MCO representatives believe that brand-name drug utilization is increasing due to prescription drug incentives such as coupons which undermines their formulary controls and in turn, increases health care costs. / text

In September 2009 exploratory testing of an old geothermal power well caused a blowout at the El Tatio geothermal field of northern Chile. El Tatio is the largest geyser field in the southern hemisphere. The blowout was a paradigm-shifting event for the management of the El Tatio geothermal field and drew attention to the disparity and critical nature of scientific information sharing. This study uses the El Tatio incident as a case study for examining problems of common-pool resource management and geothermal energy development. It explores how differing valuations of geothermal resources resulted in a breakdown of coherent regulation and negative outcomes for all stakeholders. Contingent valuation methods were used to create an elicitive interview process in order to assess how differences in valuation drove these conflicts and negative outcomes. The sharing of scientific information through Decision Support Systems (DSS) is identified as an important element in resolving these conflicts and creating new policies for common-pool resource management. These methods are presented as tools that can be used by stakeholders to find common ground and seek mutually beneficial outcomes. In addition, these tools can help with the critical issue of social perception of scientific data and science driven solutions to these problems. This study posits that the path forward is to ensure not only that scientific data is communicated in modes appropriate to the community and problem at hand, but that the acquisition and interpretation of this data is informed by stakeholder needs. / text
