Pricing for the Stars: Dynamic Pricing in the Presence of Rating Systems
No full textMaintaining good ratings increases the profits of sellers on online platforms. We analyze the role of strategic pricing for ratings management in a setting where a monopolist sells a good of unknown quality. Higher prices reduce the value for money, which on average worsens reviews. However, higher prices also induce only those consumers with a strong taste for the product to purchase, which on average improves reviews. Our model flexibly parametrizes the two effects. This parametrization can rationalize the observed heterogeneity in the relationship between reviews and prices. Based on an analytic characterization of the optimal dynamic pricing strategy, we study a platform’s choice of the sensitivity of its rating system to incoming reviews. The optimal sensitivity depends on the effect of prices on reviews and on how the platform weighs consumers and sellers in its objective. Although sellers always benefit from more sensitivity, consumers may suffer from higher prices and from slower learning from reviews due to endogenously emerging price and rating cycles

High spectral resolution analysis of tunable narrowband resonant grating waveguide structures
No full textA high spectral resolution analysis of narrowband reflection filters based on resonant grating waveguide structures is presented. A tunable high-performance dye laser with similar to 0.15 cm(-1) line width and a beam analyzing system consisting of three simultaneously controlled CCD cameras were used to investigate grating waveguide resonances at wavelengths in the 694 nm and 633 nm ranges. A reflectivity of similar to 91% and a line width of similar to 0.55 nm were measured and theoretically modeled for a resonant reflection filter specifically designed for the ruby laser wavelength 694.2 nm. For a second grating waveguide structure, designed for the helium-neon laser emission wavelength 632.8 nm, we observed a thermal shift of its spectral resonance position of several nanometers, when increasing the sample temperature by some degrees. An inverse thermal shift was observed when the structure was subsequently cooled down to room temperature. Our results suggest implementation of grating waveguide devices combining a narrow line width with a tunability of the resonant response into innovative concepts for reflection filter and sensor applications
Andre Gide and the Negro, 1940
No full textBecause it is generally known that Andre Gide is one of France's most influential contemporary writers, there is no need to justify a study based on his works. Desirous of obtaining the opinion of an influential white author concerning Negroid people and learning his activities in their behalf, the writer of this thesis undertook the study, Andre Gide end the Negro. The value of such a study to the American Negro lies primarily in (1) a better acquaintance with and appreciation for one whose interest in darker people has resulted in a tangible contribution; (2) a knowledge of the condition of a people, who, though distant in territory, are kindred in race, and (3) a challenge for scholastic accomplishment. The method of procedure was a careful analysis of Voyage au Congo and Retour du Tchad supplemented by collateral readings. To secure information concerning Mr. Gide's official investigation in 1938 of the natives' educational facilities in Senegal, a letter was sent him. Despite the anxiety which must be his because of the present war in which his country is involved, the eminent author found time to respond. His reply is quoted on page thirty-one of this study. Grateful acknowledgment is hereby given both Mr. Gide for his amicable letter and Professor Cook, who made such a contact possible. The various factors for the evolution of Gide's interest in Negroid people are shown in Chapter I. Chapter II contains a discussion of the colonial abuses existing in French Equatorial Africa exposed by Gide and his efforts to eradicate these. Through Chapter III one learns the author's personal impression of the morale and intelligence of Negroid people. In Chapter IV an interpretation of Gide's literary art in Voyage au Gang and Retour du Tchad is presented. The results are summarized in the conclusion

The report is a printed version of an internet-based reference database on the relation between birds and bats and aerial obstacles such as wind turbines, utility structures, towers and buildings. The database will be updated regularly, and is accessible via EndNote Web. At the date of printing it contains 1224 references on these topics. The database can also be used as a search engine for other databases such as ISI Web of knowledge, Biosis and others, depending on the access rights of the user.
In this printed version, the references are sorted by theme, thereafter by year of printing and author. The database is named “Birdwind”, and is administered and updated by NINA. The database is meant to be a tool that will make it easier to find relevant literature within these rapidly growing topics
Andre Gide: a study of the relationship between the author and his characters
No full textAndre Paul Guillame Gide was a controversial French writer. Some critics claimed he never wrote about anyone but himself; others denied that he used himself as a model for any but his first works. This paper is the result of a study to determine to what extent the characters of Andre Gide are autobiographical. The novel and novelle of Gide were chosen as a basis for this study because their characters are definite and their situations relatively clear. Each major character in these works was analyzed and his characteristics and actions noted in detail. Then a study was made of the author by reading his own autobiographical works and many biographies and studies of Gide. The characteristics and actions of Andre Gide were analyzed and noted. With the personalities of the author and his characters broken down into habits, characteristics and actions and organized, each character was again observed and his traits and attitudes matched with those of the author whenever this was possible. To avoid a confused jumble of characters, one book with its characters was studied at a time. [...]English, Department o

Development, Implementation, and Industry Reception of a Novel Multi-source, Data-driven Building Energy Management Toolkit
No full textInefficient and uninformed operations negatively impact building energy performance, leading to wide disparities between predicted and actual energy use in commercial and institutional buildings. Though ample research in data-driven building operations analytics has derived various methodologies for extracting energy-saving insights that can inform best practices, these approaches have traditionally remained disparate, and are mostly inaccessible to operations personnel who can benefit from these approaches in augmenting their duties and optimizing building energy efficiency. This research explores the development, implementation, and industry reception of a novel multi-source, data-driven building energy management toolkit as a synthesis of established data-driven approaches in the literature. Energy-saving insights identified from over five separate case study buildings demonstrated the toolkit's multifaceted application to identify operational deficiencies, and interviews with building operators and facility managers regarding the toolkit's outputs were conducted to identify possible barriers which may inhibit operations professionals from effectively deriving and utilizing data-driven insights
