Description
In most social networking websites, users are allowed to perform interactive activities. One of the fundamental features that these sites provide is to connecting with users of their kind. On one hand, this activity makes online connections visible and tangible; on the other hand, it enables the exploration of our connections and the expansion of our social networks easier. The aggregation of people who share common interests forms social groups, which are fundamental parts of our social lives. Social behavioral analysis at a group level is an active research area and attracts many interests from the industry. Challenges of my work mainly arise from the scale and complexity of user generated behavioral data. The multiple types of interactions, highly dynamic nature of social networking and the volatile user behavior suggest that these data are complex and big in general. Effective and efficient approaches are required to analyze and interpret such data. My work provide effective channels to help connect the like-minded and, furthermore, understand user behavior at a group level. The contributions of this dissertation are in threefold: (1) proposing novel representation of collective tagging knowledge via tag networks; (2) proposing the new information spreader identification problem in egocentric soical networks; (3) defining group profiling as a systematic approach to understanding social groups. In sum, the research proposes novel concepts and approaches for connecting the like-minded, enables the understanding of user groups, and exposes interesting research opportunities.

Description
The unmeasured Fantasias by Johann Gottfried Müthel appear as part of a collection of pedagogical exercises to foster improvisation. The information he gives in the notation of his fantasias can be elucidated with a historiographical interpretation of musical rhetoric. Müthel developed musical figures and contrasting textures in accordance with contemporary rhetorical principles of inventio, dispositio and elaboratio. An analysis of Müthel’s G-minor Fantasia provides a link between musical rhetoric and performance, as seen through its improvisatory gestures. Issues of performance practice that arise in the G-minor Fantasia are the execution of ornaments, rhythmic alterations, registration, and articulation. This paper explores primary sources contemporary to Müthel to make sense of these issues. The unmeasured Fantasias are written for a keyboard with pedal. At the time that they were written, the pedal fortepiano and pedal clavichord were seen by musicians such as Carl Phillip Emanual Bach to be the superior instruments for performing improvisations. While the notation and texture of the Fantasias suggests that Müthel intended them for organ, a consideration of the possibilities provided by the fortepiano suggests that it may be more suited to conveying aspects of the galant aesthetic.

Description
Organ culture of the late nineteenth century played an important role in the development of cities on the American Western Frontier. By 1869, the transcontinental railroad connected cities across the United States, enabling coast-to-coast travel and spawning a new tourist industry. Rail travelers stopping in Utah frequently visited the Tabernacle and were impressed by the organ, requesting to hear it played. The Salt Lake Tabernacle free daily organ recital program was initiated to meet that demand. This came at a critical time in the growth of the city as it sought to develop a positive image of itself. These organ recitals became a highlight of travelers’ journeys across the United States, shaping the image of Utah as a place of culture and refinement. Although free daily organ recital programs sprang up across the country during the early twentieth century, very few persisted for more than a decade. Today, the only two remaining continuous free daily organ recital series are given on the Salt Lake Tabernacle organ and on the Wanamaker organ in Philadelphia. Location, promotion, purpose, and programming were key factors vital to the early and continued success of the program. At a time when attendance is in decline for organ recitals, and indeed for all classical art music, the elements of this uniquely successful program may suggest new approaches for sharing organ music.

Description
Between the years of 1818 and 1833 the Austrian composer, teacher, and pianist, Carl Czerny (1791–1857) wrote one of his greatest compositions, the f minor Grand Piano Sonata, Op.178 for piano four hands. Overshadowed by composers like Ludwig van Beethoven, Frederic Chopin, Robert Schumann, Johannes Brahms and possibly because of Czerny’s prolific pedagogical output, this work has received little scholarly attention and is rarely performed.
The aim of my paper is first to provide a concise background of the composer for better insight of his ideas and influences and, second to provide a theoretical framework and analysis of the composition to show how this piece is uniquely set in the musical backdrop among early nineteenth century piano music. Further, I will demonstrate performance concepts and ideas of the composition highlighting his instructional mastery. There are two components for this project including a research paper and a lecture recital.
I hope this project could bring more musicians and audiences to Carl Czerny’s serious and concert music as he categorized his music. He had been a great model of true artist, he composes, teaches and perhaps not the greatest promoter of his own music like the contemporaries. However, he devoted most of his life to development of music and the new generation of pianists, which is the most honorable of an individual.

Description
Contemporary online social platforms present individuals with social signals in the form of news feed on their peers' activities. On networks such as Facebook, Quora, network operator decides how that information is shown to an individual. Then the user, with her own interests and resource constraints selectively acts on a subset of items presented to her. The network operator again, shows that activity to a selection of peers, and thus creating a behavioral loop. That mechanism of interaction and information flow raises some very interesting questions such as: can network operator design social signals to promote a particular activity like sustainability, public health care awareness, or to promote a specific product? The focus of my thesis is to answer that question. In this thesis, I develop a framework to personalize social signals for users to guide their activities on an online platform. As the result, we gradually nudge the activity distribution on the platform from the initial distribution p to the target distribution q. My work is particularly applicable to guiding collaborations, guiding collective actions, and online advertising. In particular, I first propose a probabilistic model on how users behave and how information flows on the platform. The main part of this thesis after that discusses the Influence Individuals through Social Signals (IISS) framework. IISS consists of four main components: (1) Learner: it learns users' interests and characteristics from their historical activities using Bayesian model, (2) Calculator: it uses gradient descent method to compute the intermediate activity distributions, (3) Selector: it selects users who can be influenced to adopt or drop specific activities, (4) Designer: it personalizes social signals for each user. I evaluate the performance of IISS framework by simulation on several network topologies such as preferential attachment, small world, and random. I show that the framework gradually nudges users' activities to approach the target distribution. I use both simulation and mathematical method to analyse convergence properties such as how fast and how close we can approach the target distribution. When the number of activities is 3, I show that for about 45% of target distributions, we can achieve KL-divergence as low as 0.05. But for some other distributions KL-divergence can be as large as 0.5.

Description
With the rise of social media, hundreds of millions of people spend countless hours all over the globe on social media to connect, interact, share, and create user-generated data. This rich environment provides tremendous opportunities for many different players to easily and effectively reach out to people, interact with them, influence them, or get their opinions. There are two pieces of information that attract most attention on social media sites, including user preferences and interactions. Businesses and organizations use this information to better understand and therefore provide customized services to social media users. This data can be used for different purposes such as, targeted advertisement, product recommendation, or even opinion mining. Social media sites use this information to better serve their users.
Despite the importance of personal information, in many cases people do not reveal this information to the public. Predicting the hidden or missing information is a common response to this challenge. In this thesis, we address the problem of predicting user attributes and future or missing links using an egocentric approach. The current research proposes novel concepts and approaches to better understand social media users in twofold including, a) their attributes, preferences, and interests, and b) their future or missing connections and interactions. More specifically, the contributions of this dissertation are (1) proposing a framework to study social media users through their attributes and link information, (2) proposing a scalable algorithm to predict user preferences; and (3) proposing a novel approach to predict attributes and links with limited information. The proposed algorithms use an egocentric approach to improve the state of the art algorithms in two directions. First by improving the prediction accuracy, and second, by increasing the scalability of the algorithms.

ABSTRACT
Emilie Mayer (1812-1883) was a prolific composer whose musical works, which encompassed eight symphonies, four overtures, an opera, dozens of sonatas, eight string quartets, solo piano works, and nearly 130 songs for solo voice or vocal quartet, were performed in the foremost concert halls in Berlin and across Germany. She studied with lauded teachers: Carl Loewe (1796-1869), Adolph Bernhard Marx (1795-1866), and Wilhelm Wieprecht (1802-1872). Her talent was applauded by audiences and critics wrote favorably, despite their reservations about women composers. However, even with this unusual pedigree, Mayer’s works nearly disappeared from concert stages after her death. How did this happen? This study aims to answer this question and will delve into Emilie Mayer’s life and works in context with the prejudices against female composers at the time, in order to determine how those biases have shaped the classical canon. Included is an in-depth stylistic analysis of Mayer’s surviving seven Lieder, along-side comparisons to similar works of other composers. In addition, appendices present Mayer’s remaining Lieder in a new, modernized edition, with selected songs transposed for better accessibility for lower voices. Relative lack of female representation in modern-day concert halls and music history books correlates to previous misconceptions of female composers. Studying the works of Emilie Mayer will support her addition to the classical repertoire, help correct the male-gendered canon that persists, and help modern female composers realize their history is not confined to a footnote.

Description
Millions of users leave digital traces of their political engagements on social media platforms every day. Users form networks of interactions, produce textual content, like and share each others' content. This creates an invaluable opportunity to better understand the political engagements of internet users. In this proposal, I present three algorithmic solutions to three facets of online political networks; namely, detection of communities, antagonisms and the impact of certain types of accounts on political polarization. First, I develop a multi-view community detection algorithm to find politically pure communities. I find that word usage among other content types (i.e. hashtags, URLs) complement user interactions the best in accurately detecting communities.
Second, I focus on detecting negative linkages between politically motivated social media users. Major social media platforms do not facilitate their users with built-in negative interaction options. However, many political network analysis tasks rely on not only positive but also negative linkages. Here, I present the SocLSFact framework to detect negative linkages among social media users. It utilizes three pieces of information; sentiment cues of textual interactions, positive interactions, and socially balanced triads. I evaluate the contribution of each three aspects in negative link detection performance on multiple tasks.
Third, I propose an experimental setup that quantifies the polarization impact of automated accounts on Twitter retweet networks. I focus on a dataset of tragic Parkland shooting event and its aftermath. I show that when automated accounts are removed from the retweet network the network polarization decrease significantly, while a same number of accounts to the automated accounts are removed randomly the difference is not significant. I also find that prominent predictors of engagement of automatically generated content is not very different than what previous studies point out in general engaging content on social media. Last but not least, I identify accounts which self-disclose their automated nature in their profile by using expressions such as bot, chat-bot, or robot. I find that human engagement to self-disclosing accounts compared to non-disclosing automated accounts is much smaller. This observational finding can motivate further efforts into automated account detection research to prevent their unintended impact.

Description
The pipe organ, a musical instrument historically, culturally, and conceptually associated with Christian worship, is being negatively affected in terms of condition and continued use in the United States by rising rates of secularity, declining mainline Protestant and Catholic adherents, declining worship attendance, and, most directly, the closure of church buildings. No scholarly research addresses the relationship of secularization and the organ, and no professionals in the field acknowledge its seriousness or have presented plans to counter it.
This paper lays the groundwork for future research while exploring the landscape of the organ’s possible secular uses. The organ’s relationship to secularization is defined through the interdisciplinary lens of secular studies, bolstered through an exploration of its past. This thesis analyzes the use of the organ in secularized churches in the United States through case studies of fourteen organs in thirteen former churches. While these examples reveal some promising adaptive reuses of church buildings and their organs, the prevailing conclusion is that the instrument’s future is severely endangered. There are few paid secular positions and insignificant educational opportunities that stem from secularized churches. The public lacks exposure to the instrument because of the infrequency of organ-related events.
Yet because the organ’s principal aesthetic is not Christian but communal, the instrument has the potential to thrive in secular contexts. This reframing and often literal repositioning requires stronger leadership: organizations and individuals promoting the organ must be proactive in working with the new owners of secularized churches to help them incorporate the instrument in new, revitalized contexts. A dynamic future for the organ requires the creative work of many.

Description
Henri Constant Gabriel Pierné (1863-1937) was a French composer and conductor. Given his position of importance during his life alongside César Franck, Claude Debussy, and Camille Saint-Säens, Pierné’s musical oeuvre has largely gone unrecognized in the modern musical canon. Scholarly literature on Pierné is severely limited; currently, there is only one identified biography about Pierné, written in French by author Georges Masson ain 1987. To date, no formal analysis exists of Pierné’s Sonata for Violin and Piano, Opus 36 (1900). This document provides an account of Pierné’s life and style, gleaned in particular from this author’s original English translation of Masson’s definitive text. It also delivers the first known scholarly musical analysis of the sonata. Each chapter discusses a particular movement in depth, considering the elements of Structure, Harmony, Melody, Rhythm, and Texture, while illustrating contextual trends and potential influences across all three movements. The document concludes with the author’s original score analysis charts as well as a comprehensive bibliography. The discussion herein illuminates aspects of Pierné, and specifically his sonata for violin and piano, to promote greater awareness of a composer whose work merits elevated recognition beyond his current reputation of semi-obscurity.
