Engaging Lives: a Nomadic Inquiry Into the Spatial Assemblages and Ethico-aesthetic Practices of Three Makers

Description: This research is a nomadic inquiry into the ethics and aesthetics of three makers’ social and material practices. Deleuze’s concept of the nomad operated in multiple ways throughout the process, which was embedded in performative engagements that produced narratives of becoming. Over four months, I built relationships with three people as I learned about the ethico-aesthetic significance of their daily practices. The process started by interviewing participants in their homes and expanded ov… more

Identifying Opportunities for the Revitalization of Downtown Bloomsburg

Description: American downtowns were once the place to see and be seen, but the introduction of the shopping mall in the late 1950s challenged this notion and gave the American consumer a different place to spend their time and money. The prevalence of shopping malls has slowly been declining across the country since the beginning of this century, leaving room in the American retail landscape for downtowns to reclaim their status as community and retail centers. Towns across the U.S. are turning to nationa… more

Increasing the Players: Expanding the Bilateral Relationship of Conflict Management

Description: This research seeks to explore the behavior of international and regional organizations within conflict management. Previous research on conflict management primarily examines UN peacekeeping as the primary actor and lumps all non-UN actors into a single category. I disaggregate this category, examining how international and regional organizations interact when deciding to establish a peace mission, coordinate a peace mission with multiple organizations, and finally, how this interaction affe… more

Product Management: the Decision Process

Description: This thesis builds upon several theoretical ideas. The first of which is the anthropologists’ transition into the corporate context and the particular type of skills and value that someone with anthropological training can bring to operations management. As anthropology is relatively new and unfamiliar to corporations, anthropologists are often hired without explicit knowledge of how they will address organizational problems. Frequently, this incremental relationship building between the anthro… more

Exploratory Analysis of Social E-health Behavior

Description: Extant literature has documented well that people seek health information via the internet as patients and consumers. Much less, however, is known about interaction and creation behaviors in the development of new online health information and knowledge. More specifically, generalizable sociodemographic data on who engages in this online health behavior via social media is lacking in the sociological literature. The term “social e-health” is introduced to emphasize the difference between seekin… more

Design and Application of a New Planar Balun

Description: The baluns are the key components in balanced circuits such balanced mixers, frequency multipliers, push–pull amplifiers, and antennas. Most of these applications have become more integrated which demands the baluns to be in compact size and low cost. In this thesis, a new approach about the design of planar balun is presented where the 4-port symmetrical network with one port terminated by open circuit is first analyzed by using even- and odd-mode excitations. With full design equations, the p… more

Using Baroque Vocal Music to Introduce Horn Students to the Musical Concepts of Expression, Articulation, Phrasing, and Tempo

Description: Baroque music is an area largely neglected in the music education of young horn students and wind players in general. Baroque horn repertoire is very demanding primarily due to the range. Baroque composers wrote for horn using the uppermost register of the instrument. In this range the partials are closer together, allowing for more melodic writing. This music requires an advanced level of technique, endurance, and ability. Often this repertoire is not suitable for students until they are … more
