In 2014, the European Union and its members agreed to reduce carbon dioxide emissions by 40 percent before 2030. The Bonus-Malus, a feebate tax scheme, was introduced in Sweden in 2018 in the hopes that it would result in lower carbon dioxide emission from Sweden’s transport sector. Sweden’s feebate is a regulatory measure to achieve an efficient cost-constrained environmental policy, thus reduce the negative externalities from the transport sector. Using a Difference-in-Differences approach, this paper aims to determine who benefits from tax incentives created from the implementation of the feebate tax in Sweden using panel data of list prices and vehicle characteristics between 2015 and 2020. The results indicates that there is no long-run price effect when introducing the Swedish feebate tax. Moreover, the results from the additional analysis indicate that the manufacturers’ list price adjustments to the Swedish feebate tax are overshadowed by the introduction of the EU carbon dioxide emission standards because of the close time proximity between the two policy measures. The lack of list price adjustments enables consumers in Sweden to exploit an arbitrage opportunity in that they can gain the entirety of the subsidy but also suffer the entire cost of the malus fees.

There are numerous applications for airborne imaging systems in remote sensing, and this thesis deals with a new microwave polarimetric radiometer technique for inferring ocean surface wind direction [3, 5, 7]. This technique is based upon the anisotropy of the polarized ocean blackbody emissions at microwave frequencies relative to the azimuth angle between the microwave radiometer antenna "look" direction and the direction of the wind. Because of the weak wind direction signature, it is important that all systematic brightness temperature (Tb) errors be eliminated, especially those that vary with the radiometer antenna scan position (look direction). This can be accomplished either in hardware implementation or through data processing corrections. Unfortunately, the misalignment of the axis of rotation for a conical-scanning imager can introduce such azimuthally dependent errors of significant magnitude. As the title suggests, the analysis of the resulting Tb errors caused by static and dynamic time-varying aircraft attitude errors is the main thrust of this thesis. In this thesis, we present analytical models developed to account for platform attitude changes on measured ocean microwave brightness temperature collected by a conically scanning radiometer. Data processing procedures for removing unwanted variations in ocean brightness temperatures are outlined. The analytical models are validated by making comparisons between modelled and measured Tb's obtained by the Conically Scanning Two-Look Airborne Radiometer (C-STAR). Results demonstrated that the analytical Tb model can accurately predict the measured polarized Tb's under actual flight conditions.

In the U.S. students in public schools with disabilities are protected via special education services under the Individuals with Disabilities Education Act (Individuals with Disabilities Education Act, 2004). As part of these regulations, schools are required to provide students aged 16 years and older with transition services to prepare them for life as adults. Research shows that there are links between participation, social engagement, work and well-being (Cacioppo, et al., 2014; Gilson, et al., 2022; Holt-Lunstad, 2018; Macdonald, et al., 2018) as well as a link between social isolation and increased mortality and morbidity (Snyder-Mackler, et al., 2020; Yang, et al., 2016), and yet parents of individuals with moderate to severe/profound, complex, or low-incidence disabilities do not always have transition experiences they feel set their child up for success in real-life situations (Lee & Kim, 2021; Snell-Rood, et al., 2020). This research study used a mixed methods structure to obtain research regarding parent perspectives on specific areas schools need to address to create strong and meaningful transition plans for their students who have more involved disabilities and may require more support. A literature review, a web-based parent survey, 6 one-to-one interviews, and a focus group of 4 interview participants were conducted to drive development of an online, self-paced instructional course comprised of five modules designed to be implemented with school administrators and IEP team members (including, but not limited to teachers, related service providers, psychologists, support staff, parents and students) highlighting immediately implementable strategies to strengthen the IEP transition process in which they participate. Results compiled from all sources support five main areas or themes for creating meaningful transition: collaboration/team/relationships, community based/real-life instruction, presumed competence/mindset, knowledge, and skills (of the parent and school team members), and individualizing the IEP. Additional research supports the use of specific team members (e.g. vocational rehab transition specialist (Plotner & Dyamond, 2017)) and a case is made for ensuring transition teams for students with moderate to severe/profound, complex or low-incidence disabilities include occupational therapists who are trained in the value of using meaningful participation to improve quality of life for their clients (AOTA, 2020). / Temple University.

<p>Subjects enrolled in a clinical trial may experience a competing risk event which alters the risk of the primary event of interest. This differs from when subject information is censored, which is non-informative. In order to calculate the cumulative incidence function (CIF) for the event of interest, competing risks and censoring must be treated appropriately; otherwise estimates will be biased. There are two commonly used methods of calculating a confidence interval (CI) for the CIF for the event of interest which account for censoring and competing risk: the Kalbfleisch-Prentice (KP) method and the Counting Process (CP) method. The goal of this paper is to understand the variances associated with the two methods to improve our understanding of the CI. This will allow for appropriate estimation of the CIF CI for a single-arm cohort study that is currently being conducted. Previous work has failed to address this question because researchers typically focus on comparing two treatment arms using statistical tests that compare cause-specific hazard functions and do not require a CI for the CIF. The two methods were compared by calculating CIs for the CIF using data from a previous related study, using bootstrapping, and a simulation study with varying event rates and competing risk rates. The KP method usually estimated a larger CIF and variance than the CP method. When event rates were low (5%), the CP method is recommended as it yields more consistent results than the KP method. The CP method is recommended for the proposed study since event rates are expected to be moderate (5-10%).</p> / Master of Science (MS)

Forest property taxes play an integral role when private landowners make land use and management decisions. Economists often suggest that taxes should be neutral, thus causing no change in land use or management decisions compared to the pre-tax condition. The traditional ad valorem property tax has long been criticized, particularly as it pertains to forestry, because of its distortionary properties and inherent bias against long-rotation investments. Alternatives to the traditional forest property tax include current use assessment, productivity, yield, and site value taxes. The site value tax is a property tax on the market value of bare land only, exempting improvements. In theory, the site value tax has been championed as the only neutral property tax alternative; however, in actual application, a forest site value tax may prove to be non-neutral and, by certain measures, inequitable. The degree of the tax's neutrality can be linked to the method of tax administration and the ability of assessors to accurately determine bare land market values for a wide range of site qualities. This paper reviews literature on forest property tax alternatives and theoretically examines the efficiency of an applied forest site value tax. The adequacy and equity of a proposed forest site value tax are examined in detail and compared for two study areas: Western Oregon and Alabama; in light of local governmental budget constraints. Although the site value tax may represent a less-distortional vehicle for collecting local taxes, it is unlikely to be politically or administratively feasible. Also, given the existence of other distortions in the economy, a site value tax may not prove to be the most efficient tax in application, despite its neutral properties. / Master of Science

Thèse numérisée par la Direction des bibliothèques de l'Université de Montréal / Cette thèse présente une analyse de la détermination des salaires et de l'activité de grève dans le marché du travail. On s'éloigne des modèles d'équilibre général pour se tourner vers des modèles d'équilibre partiel qui prennent en compte la complexité des comportements stratégiques des agents au sein des liens institutionnels qui définissent les possibilités de leur action. Dans cette thèse, nous utilisons la théorie des contrats et la théorie des jeux non-coopératifs pour modéliser l'évolution des salaires, expliquer l'activité de grève et tester l'incidence des grèves sur cette évolution des salaires.

Le cancer occupe le premier rang parmi les causes de décès au Québec. Les taux de mortalité diffèrent cependant à travers les régions du Québec. En considérant les territoires des Centres de santé et de services sociaux (CSSS), ce mémoire propose dans un premier temps d’étudier la distribution des taux de mortalité pour les principaux sièges de cancer, d’identifier les régions où une différence significative du taux avec le reste du Québec est perceptible et d’approfondir des éléments impliqués dans la mortalité, soit l’incidence et la létalité. D’autre part, dans le but d’expliquer les variations des taux de mortalité, des variables socio-économiques liées aux territoires retenus serviront de variables explicatives au modèle de régression utilisé. Les résultats ont permis de constater que c’est pour le cancer du poumon que les écarts significatifs sont les plus nombreux. Quant au cancer colorectal, un seul territoire présentait un écart significatif. Pour ce qui est du cancer de la prostate et du sein, aucun écart n’est perceptible dans les taux de mortalité. Concernant la partie explicative de la mortalité, dans le cas du cancer du poumon, les taux d’incidence sont fortement corrélés aux taux de mortalité. On ne peut cependant faire le même constat pour les cancers colorectal, du sein et de la prostate. De plus, les variables socio-économiques considérées pour les territoires de CSSS ne permettaient pas d’arriver à un modèle explicatif convaincant. Ces résultats montrent la nécessité d’avoir des données longitudinales permettant de suivre les individus dès le moment où le diagnostic de cancer est établi afin d’être en mesure de mieux mesurer les liens entre l’incidence, la survie, le niveau socio-économique et la mortalité. / Cancer is the leading cause of death in Québec. However, mortality rates vary significantly throughout Quebec’s regions. Using the CSSS (Centre de santé et de services sociaux) territories as a base of comparison, the present thesis will study the regional distribution of mortality rates amongst the territories with the highest cancer rates, identify those territories that have a significant variation from the overall cancer rate of the province, and investigate the relation between incidence rates and lethality. Moreover, to help explain variations in mortality rates, a regression analysis was undertaken using socioeconomic variables of each territory. The analysis demonstrated that territorial disparity was the greatest for lung cancer. As for colorectal cancer, only one territory showed a rate different with that of Quebec as a whole. For prostate and breast cancer no variations were identified. Lung cancer mortality rates were found to be strongly correlated with incidence rates, but that wasn’t the case for the other cancers (colorectal, breast and prostate). Further, the analysis of the socio-economic variables in the regression model did no present any convincing results. The need for longitudinal data to study mortality rates by cancer and its associated factors is deemed to be a major issue.
