    Content: We introduce a powerful method for cleaning time series - Multi-Channel Singular Spectrum Analysis (MSSA). “Cleaning” means filling data gaps and removing unphysical spikes, which are chronic problems. MSSA utilizes all available information in “time” and “space” with autocorrelations, correlations, and lagged correlations. MSSA performs demonstrably better than other methods. Here we present tests using MSSA to fill data gaps, with positive results. Spike removal is in a separate paper

    Content: Nous étudions les adverbes morphologiquement marqués par le suffixe -ment en français et leurs équivalents en chinois. Grâce au suffixe -ment, les adverbes français sont facilement identifiables en termes de partie du discours, mais au sein même de l'ensemble de cette classe, leur comportement syntaxique et sémantique varie. Selon leur portée, ils sont subdivisés en « adverbes de phrase » et en « adverbes de constituant ». Comme leur dénomination l'indique, les adverbes de phrase s'associent à l'énoncé tout entier ; en revanche, les adverbes de constituant se rapportent seulement à un/des constituant(s) de l'énoncé. Deux tests syntaxiques permettent d'identifier leur statut: la négation et la construction clivée. Ensuite, les adverbes de phrase et les adverbes de constituant sont subdivisés selon leurs sens. En se fondant sur la classification des adverbes français, on étudie les équivalents chinois de chaque sous-classe d'adverbes français. En tant que langue isolante, le chinois a une morphologie relativement pauvre. Le suffixe -ment n'a pas de forme correspondante homogène en chinois : ses équivalents chinois peuvent se présenter entre autres sous forme d'adverbe ou de locution adverbiale. Tout comme en français, en chinois, la négation et la construction clivée servent aussi de tests syntaxiques pour opposer les adverbiaux de phrase aux adverbiaux de constituant. Mais les critères syntaxiques du français ne peuvent être utilisés directement. C'est pourquoi on en propose de nouveaux, comme la question en shi-bu-shi "être-Nég.-être". A l'issue de l'analyse, le classement des équivalents chinois des adverbes français en -ment est établi
    Content: This thesis studies French adverbs that are morphologically marked with a -ment suffix and of their Chinese equivalents. Due to the suffix -ment, French adverbs are easily identifiable in terms of parts of speech, but within this whole class, subclasses based on their syntactic and semantic differences are posited. According to their scope, adverbs are classically subdivided into « sentential adverbs » and « constituent adverbs ». As hinted by their denomination, phrase adverbs are associated with the whole sentence; whereas constituent adverbs are only related to one or several constituents. Two syntactic tests are used to pinpoint their difference: negation and clefting. Then sentential adverbs and constituents are subclassified adverbs according to their meaning differences. Based on the classification of French adverbs, I study the Chinese equivalents of each subclass of French adverbs. As an isolating language, Chinese has a scanty morphology. The French suffix -ment doesn't have a homogeneous corresponding form in Chinese: the Chinese equivalents of the French adverbs cans be adverbs or adverbial phrases. As in French, negation and clefting also function as syntactic tests to oppose phrase adverbs and constituent adverbs. But the syntactic criterions in French cannot be used directly in Chinese. That's why I propose new tests, such as the compatibility with the question shi-bu-shi "be-Neg.-be". Our analysis finally leads to establish a classification of Chinese equivalents to the French adverbs -ment

    Content: Fair lending analysis of non-mortgage credit products often involves proxying for race/ethnicity since such information is not required to be reported. Using mortgage data, this paper evaluates a series of proxy approaches (geo, surname, geo-surname, and BISG) as compared with the race/ethnicity reported under HMDA. The BISG proxy predicts the reported race/ethnicity the best as judged by prediction bias, correlation coefficient, and discriminatory power. In assessing fair lending risks where classification of race/ethnicity is called for, we propose the BISG maximum classification, which produces a more accurate estimation of mortgage pricing disparities than the current practices. The above conclusions withhold various robustness tests. Additional analysis is performed to assess the proxies on non-mortgage credits by leveraging consumer credit bureau data

    Content: Motivated by a widely observed phenomenon in China that female college students outperform male students in economics and most of social science subjects, this paper examines gender differences in student performance in the intermediate microeconomics course in China. In stark contrast to what has been documented in the existing literature, which primarily focuses on developed countries and the U.S. in particular, I find that holding constant observed student characteristics, female students on average appear to earn higher scores than male students in China. I find that this is not because of female students’ ability, family background and other unobservable student characteristics. Instead, it is simply a result of female students exerting more effort than male students. I further explore a wide range of possible explanations for the gender difference in diligence, but find little support for any of the explanations. Despite this, my results indicate that there is no systematic discrimination against female students in the Chinese college education system

    Content: Nitrification is increasingly of concern in US potable water systems, due to changes from chlorine to chloramine as a secondary disinfectant in order to comply with new regulations for disinfectant by-products. The ammonia that is released from the chloramine decay supports nitrification. A comprehensive literature review systematically examined the complex inter-relationships between nitrification, materials corrosion and metals release. That analysis suggested that nitrification could accelerate decay of chloramine, enhance corrosion of water distribution system materials, and increase leaching of lead and copper to potable water under at least some circumstances. Moreover, that certain plumbing materials would inhibit nitrification, but that in other situations the plumbing materials would enhance nitrification. Experiments verified that nitrification could affect the relative efficacy of chlorine versus chloramine in controlling heterotrophic bacteria in premise plumbing. Without nitrification, chloramine was always more persistent and effective than chlorine in controlling biofilms. But with nitrification and in pipe materials that are relatively non-reactive with chlorine, chloramine was much less persistent and less effective than chlorine. In materials that are reactive with chlorine such as iron pipes, the relative efficacy of chloramine versus chlorine depends on the relative rate of corrosion and rate of nitrification. High rates of corrosion and low rates of nitrification favor the use of chloramine versus free chlorine in controlling bacteria. Plumbing materials had profound impacts on the incidence of nitrification in homes. Effects were due to toxicity (i.e., release of Cu²), recycling of nitrate back to ammonia substrate by reaction (zero-valent iron, lead or zinc materials), or release of nutrients that are essential to nitrification by leaching from concrete or other materials. As a general rule it was determined that concrete and iron materials encouraged growth of nitrifiers in certain oligotrophic waters, materials such as lead, PVC/plastic pipe, glass and surfaces of other materials were readily colonized by nitrifiers, and materials such as copper and brass were very toxic and relatively resistant to nitrifier colonization. Dependent on circumstance, nitrification had no effect, increased or decreased aspects of materials corrosion. Nitrification markedly increased lead contamination of low alkalinity potable water by reducing the pH. In some cases nitrification dramatically decreased leaching of zinc to potable water from galvanized iron, because of lowered dissolved oxygen and reduced pH. Nitrification did not affect copper solubility in low alkalinity water, but is expected to increase copper solubility in higher alkalinity waters. Finally, nitrification in homes plumbed with PVC or plastics can drop the pH and increase leaching of lead from downstream brass materials in faucets. This can explain why some modern homes plumbed with PVC can have more lead in water when compared to homes plumbed with copper pipe. Phosphate had profound impacts on the incidence of nitrification and resulting effects on water quality. While phosphate levels below about 5 ppb could strongly inhibit nitrification due to a nutrient limitation, nitrifiers can obtain sufficient phosphate from plastic, concrete, copper and iron pipe materials to meet nutritional needs. High levels of phosphate inhibitor can reduce the concentration of Cu² ions and make nitrification more likely, but phosphate can also sometimes lower the corrosion rate and increase the stability of disinfectant and its efficacy in controlling nitrifiers. Phosphate plays a key role in determining where, when and if problems with nitrification will occur in a given water distribution system. This work provides some new fundamental and practical insights to nitrification issues through a comprehensive literature review, lab experiments, solubility modeling and field studies. The results and practical tools developed can be used by utilities and consumers to predict nitrification events and resulting water quality problems, and to make rational decisions about practices such as inhibitor dosing, plumbing material selection and use of whole house filters. ; Ph. D.
