A Short Text Classification Method Based On Convolutional Neural Network And Semantic Extension, Haitao Wang, Keke Tian, Zhengjiang Wu, Lei Wang
A Short Text Classification Method Based On Convolutional Neural Network And Semantic Extension, Haitao Wang, Keke Tian, Zhengjiang Wu, Lei Wang
Faculty Publications
In order to solve the problem that traditional short text classification methods do not perform well on short text due to the data sparsity and insufficient semantic features, we propose a short text classification method based on convolutional neural network and semantic extension. Firstly, we propose an improved similarity to improve the coverage of the word vector table in the short text preprocessing process. Secondly, we propose a method for semantic expansion of short texts, which adding an attention mechanism to the neural network model to find related words in the short text, and semantic expansion is performed at the …
Analyzing Perceptions Of Citizen Science As Part Of An International Learning Experience, Katelyn Marie Miner
Analyzing Perceptions Of Citizen Science As Part Of An International Learning Experience, Katelyn Marie Miner
Dissertations and Theses @ UNI
This study focused on a perceptions-based citizen science project that emphasizes meaning over measurement. Specifically, student perceptions of citizen science in a unique location, rather than the specific data outcomes of the water quality citizen science activity were analyzed. Many researchers have used citizen science participants to collect samples from water sources around them, increasing the use of mass data collection for scientific purposes.This study was a mixed-methods design, using triangulation of the pre-survey, modified focus group, and post-survey. The goal was to gauge the perceptions of participants in perceived benefits and gains before and after participating in a water …
Spatiotemporal Observations Of Water Stress In Kansas Winter Wheat And Corn From Remotely Sensed Evapotranspiration And Ndwi, Lindi Diane Oyler
Spatiotemporal Observations Of Water Stress In Kansas Winter Wheat And Corn From Remotely Sensed Evapotranspiration And Ndwi, Lindi Diane Oyler
Masters Theses
"Optimizing water use is a growing concern, especially in agricultural communities where water use is high. An important challenge in agricultural water optimization is knowing when and where crop water stress is occurring, particularly on large scales where in-situ measurements are no longer practical to obtain. In an effort to combat this challenge, this study utilizes remotely sensed evapotranspiration (ET) and Normalized Difference Water Index (NDWI) to evaluate the responses of integrated satellite datasets to water-stressed conditions over fields of irrigated corn, irrigated winter wheat, and rainfed winter wheat from 2007 to 2017 in southwestern Kansas. Using two different ET …

The Use Of Distraction: Doomscrolling, Losing Time, And Digital Well-Being In Pandemic Space-Times, Jacob Saindon
The Use Of Distraction: Doomscrolling, Losing Time, And Digital Well-Being In Pandemic Space-Times, Jacob Saindon
Theses and Dissertations--Geography
In the space-times of the COVID-19 global health crisis, how have our relationships with smartphones changed? How do popular discourses designate mundane engagements with digital technologies as healthy or unhealthy, and how are these notions of wellness practiced? This thesis draws upon an online survey of smartphone users residing in Kentucky, and a review of marketing, journalistic, and academic literature to establish current understandings of ‘digital well-being’. The paper then analyzes interviews with Kentucky smartphone users who were asked to track their screen time for a one-week period. This project reveals normative conceptions of well-being and the role of smartphone …
Countering ‘Plastic Addicted Subjects’: Power, Essentialized Identities, And Expertise In Thailand, Olivia Carter Meyer
Countering ‘Plastic Addicted Subjects’: Power, Essentialized Identities, And Expertise In Thailand, Olivia Carter Meyer
Theses and Dissertations--Geography
Thailand is considered one of the six most significant contributors to marine plastic pollution in the world. This has led to widespread media attention and condemnation of Thai people as “addicted to plastic,” with little attention paid to how such discourses actually take shape. Drawing from semi-structured interviews with Thai regulatory institutions, grassroots environmental organizations, plastic industry representatives, and recyclers, I analyze the social, political, economic, and environmental processes that shape Thailand’s plasticscapes. I propose a feminist political ecology of plastic waste which attends to people’s lived experiences and perspectives, power relationships underlying discourses that inform the issue, and Thai …
Debilitating Debts And Recapacitating Loans: How Fintech Made Markets For Unsecured Consumer Debt Using Alternative Data And Machine Learning, Michael Joshua Mccanless
Debilitating Debts And Recapacitating Loans: How Fintech Made Markets For Unsecured Consumer Debt Using Alternative Data And Machine Learning, Michael Joshua Mccanless
Theses and Dissertations--Geography
This thesis investigates the production and management of consumer debt on digital platforms. First, this study investigates how borrowers navigate spaces of debt and indebtedness created by fintech consumer lenders. Second, this thesis analyzes the process and impact of ‘alternative’ data and machine learning on fintech credit scoring models. As consumer lending ‘moves online’, this research analyzes the increasingly important role of digital spaces in the creation and management of debt. Tracking the interfaces and algorithms used by online consumer lenders, I weave together insight from digital and financial geographies to argue that digital technologies are enabling firms to marketize …
Uncovering Frontier Mythologies: Memorial Landscapes In Minneapolis, Mn, Corrin Turkowitch
Uncovering Frontier Mythologies: Memorial Landscapes In Minneapolis, Mn, Corrin Turkowitch
Theses and Dissertations--Geography
This thesis analyzes the relationship between settler colonialism and public memory in B.F. Nelson Park, a downtown park in Minneapolis. My focus is the Pioneer statue, a large granite memorial depicting a frontier family in the middle of the park, which I examine through the lenses of race, gender, power, and violence. Using archival and landscape analysis I examine the historical and present built environment of the park and how it relates to white supremacy. Through interviews of two municipal constituencies, I evaluate how these organizations maintain present narratives of European settlement and in turn uphold the monument. This research …
Gentrification And The Black Church: Mitigating Black Suburban Displacement In A Post Covid-19 World, Jordan Mccray
Gentrification And The Black Church: Mitigating Black Suburban Displacement In A Post Covid-19 World, Jordan Mccray
Theses and Dissertations--Geography
Black churches have been playing an important, stabilizing and supportive role for their members, their neighborhoods, and their communities more broadly. However, these churches’ memberships, community functions, and abilities to support their members have been threatened by the accelerating displacement of African Americans due to the ongoing effects of gentrification, defined by massive economic investment in low-income areas leading to the displacement of low-income residents. At the same time, COVID-19 has also changed the ways churches are able to deliver their support and outreach, with some moving their services to be completely virtual, and many outreach programs having to be …
Procuring Produce In A Rural, Appalachian County: A Thematic Analysis Of Community Member Experiences, Caroline Blincoe
Procuring Produce In A Rural, Appalachian County: A Thematic Analysis Of Community Member Experiences, Caroline Blincoe
Theses and Dissertations--Nutrition and Food Systems
Rates of obesity and other health disparities are exceptionally high in rural Appalachian counties compared to the nation as a whole. One causal factor of these health disparities in Appalachian counties is the inequitable allocation of healthy food. Food insecurity and the local food environment are large drivers for obesity experienced by Martin County, Kentucky residents. Successful socioecological model (SEM) and policy, systems, and environmental (PSE) interventions have shown promising results in reducing obesity and enhancing food security in this population. Through the transcription of semi-structured focus group interviews, thematic analysis aimed to obtain perspectives on the local food system. …
The Kiwanis Site: A Multi-Method Geophysical Approach To Investigating Mound Features, Luke Burds
The Kiwanis Site: A Multi-Method Geophysical Approach To Investigating Mound Features, Luke Burds
All Graduate Theses, Dissertations, and Other Capstone Projects
Subtle mound-like landforms can be genetically ambiguous features within a landscape. A variety of geomorphological and anthropological processes can result in these equifinal forms being difficult to interpret. Being able to reliably and noninvasively differentiate them is important for legal as well as cultural and spiritual reasons. A suite of non-invasive geophysical methods were thus used on mounds at the Kiwanis site in western Wisconsin in order to determine if culturally diagnostic indicators could be recorded in geophysical data. Genesis of these mounds is ambiguous given the presence of aeolian landforms in immediate proximity. As a control, the same geophysical …
Quantifying Carbon Sequestration For Riparian-Zone Restoration In Ecuador, Paula Carvalho De Castro
Quantifying Carbon Sequestration For Riparian-Zone Restoration In Ecuador, Paula Carvalho De Castro
Dissertations and Theses @ UNI
Carbon sequestration supported by carbon pricing and carbon offset programs has the potential to mitigate the risks associated with environmental change. Riparian-zone restoration, beyond enriching degraded ecosystems, promotes carbon sequestration. With that premise, this study aims to estimate and compare how much carbon is captured and stored using six riparian-zone restoration scenarios for the Northwestern part of the Pichincha Province in Ecuador and the economic value of the respective carbon. The InVEST Carbon Storage and Carbon Sequestration Model which integrates land cover maps, carbon pools, and economic value of carbon in currency units was used to quantify the amount of …
Effects Of States’ Laws On Youth Physical Activity Participation And Obesity Prevalence, Chae Young Chang
Effects Of States’ Laws On Youth Physical Activity Participation And Obesity Prevalence, Chae Young Chang
Midwest Social Sciences Journal
The alarming prevalence of obesity and lack of physical activity among adolescents led to immediate policy action to address these concerns. Accordingly, many states introduced and enacted their own legislation to encourage physical activity in schools. Few studies have explored the effectiveness of the new legislation, however, especially at the state level. To answer the fundamental question of whether policy is effective and to describe the varying effects of state obesity policies, this study analyzed the Youth Risk Behavior Surveillance System from 2007 to 2017. Using the difference-in-differences method, this study found that legislative efforts to encourage physical activity had …
