The Role Of Uncertainty In Categorical Perception Utilizing Statistical Learning In Robots, Nathaniel V. Powell
The Role Of Uncertainty In Categorical Perception Utilizing Statistical Learning In Robots, Nathaniel V. Powell
Graduate College Dissertations and Theses
At the heart of statistical learning lies the concept of uncertainty.
Similarly, embodied agents such as robots
and animals must likewise address uncertainty, as sensation
is always only a partial reflection of reality. This
thesis addresses the role that uncertainty can play in
a central building block of intelligence: categorization.
Cognitive agents are able to perform tasks like categorical perception
through physical interaction (active categorical perception; ACP),
or passively at a distance (distal categorical perception; DCP).
It is possible that the former scaffolds the learning of
the latter. However, it is unclear whether DCP indeed scaffolds
ACP in humans and …
Factors Influencing Mode Choice For Intercity Travel From Northern New England To Major Northeastern Cities, Sean Patrick Neely
Factors Influencing Mode Choice For Intercity Travel From Northern New England To Major Northeastern Cities, Sean Patrick Neely
Graduate College Dissertations and Theses
Long-distance and intercity travel generally make up a small portion of the total number of trips taken by an individual, while representing a large portion of aggregate distance traveled on the transportation system. While some research exists on intercity travel behavior between large metropolitan centers, this thesis addresses a need for more research on travel behavior between non-metropolitan areas and large metropolitan centers. This research specifically considers travel from home locations in northern New England, going to Boston, New York City, Philadelphia, and Washington, DC. These trips are important for quality of life, multimodal planning, and rural economies. This research …
Placing Natural Resource Decisions In Social And Historical Contexts: Sociological Inquiries Into Agency Communications, Management Rationalities, And Community Change, Emilian Geczi
Graduate College Dissertations and Theses
A sociological understanding of natural resource management decisions traces the links between historical change (How does this historical period differ from other periods?), society (What social relations exist at this time and how do they persist or change?), and individuals (What types of conduct and discourse prevail in this society and in this period?). The papers submitted for this dissertation examine the connections between identity, social milieu, and historical change relative to three resource management issues:
(1) The promotion of nature play areas as a novel landscape form. Analysis of agency materials suggests that these spaces are advertised as bucolic …
Influence Of Mission, Audience, And Policy Context On Issue Framing: A Case Study Of Mobilization Against Hydraulic Fracturing In The Marcellus Shale, Rezwana Zafar
Graduate College Dissertations and Theses
The case of mobilization against hydraulic fracturing by interest groups provided an opportunity to examine the influence of three factors (mission, audience, and policy context) on diagnostic, prognostic, and motivational framing. A comparative analysis was conducted of the mobilization activities of five national environmental organizations with a local presence in the Pennsylvania and New York Marcellus Shale regions. The organizations varied with respect to organizational mission, the audiences they were targeting (urban and rural), and the policy context in which they worked (pro and anti-hydraulic fracturing). Data came from eleven semi-structured in-depth interviews with organization personnel, and from the organizations' …
The Role Of Transportation In Expanding The Democratic Ideal Of National Parks, Xiao Xiao
The Role Of Transportation In Expanding The Democratic Ideal Of National Parks, Xiao Xiao
Graduate College Dissertations and Theses
National parks have famously been called "America's best idea" and preserve the nation's natural and cultural resources for the enjoyment of all. One of the current working priorities of the National Park Service (NPS) is enhancing the relevancy and engagement of the national parks with diverse audiences, especially for underserved groups. To address this priority, transportation is needed to provide access to national parks, but transportation may not be equally accessible to all groups in society. Understanding the effects of transportation on visitation to the national parks by racial/ethnic groups is essential for the NPS to improve the accessibility of …
Mathematical Modeling Of Public Opinion Using Traditional And Social Media, Emily Cody
Mathematical Modeling Of Public Opinion Using Traditional And Social Media, Emily Cody
Graduate College Dissertations and Theses
With the growth of the internet, data from text sources has become increasingly available to researchers in the form of online newspapers, journals, and blogs. This data presents a unique opportunity to analyze human opinions and behaviors without soliciting the public explicitly. In this research, I utilize newspaper articles and the social media service Twitter to infer self-reported public opinions and awareness of climate change. Climate change is one of the most important and heavily debated issues of our time, and analyzing large-scale text surrounding this issue reveals insights surrounding self-reported public opinion. First, I inquire about public discourse on …
