Essays On Public And Nonprofit Financial Dynamics, Yunjun Kim

Theses and Dissertations--Public Policy and Administration

This dissertation consists of three essays that explore different dimensions of financial dynamics in the public and nonprofit sectors. Each chapter examines how the fiscal behavior of neighboring jurisdictions, policy interventions, and financial practices influence fiscal decision-making and financial performance within these entities.

In the first essay, I investigate yardstick competition in local government spending in South Korea by leveraging the exogenous variation introduced by by-elections. This approach allows me to estimate the influence of neighboring jurisdictions on local expenditures. Contrary to previous empirical studies from other countries, my findings reveal no significant interdependence in spending among South Korean municipalities, …

The Intersection Of Asset Management And Geographic Information Systems For University Facilities Maintenance, Andrew Westerlund Beland

Masters in GIS Practicum Reports

This project describes a proof of concept for developing a digital asset management system dashboard for water backflow assemblies at Portland State University (PSU) using a modified ESRI ArcGIS Online backflow solution. Asset management is crucial for optimizing the lifecycle of tangible assets, which ensures cost-effective operational efficiency and regulatory compliance. PSU manages over 250 backflow assemblies spread across the 50-acre campus and has traditionally relied on manual processes, which can lead to inefficiencies and potential transcription errors.

The system links spatial data with asset attributes for backflow devices, enabling field staff to update inspection results directly from mobile devices. …

Generating Climate Resilience Or Intensifying Vulnerabilities? A Feminist Poltitical Ecology Analysis Of Climate Resilient Agriculutre Projects In Sri Lanka’S Dry Zone, Nethmi Sachithma Perera Bathige

Theses and Dissertations--Geography

Conserving water for irrigation of crops has become a concern in the dry zone of Sri Lanka due to changes in climate patterns. In response, the United Nations Development Program (UNDP) has developed climate-resilient water management projects designed to build climate-resilience and water management practices among farmers. One such program called ‘Wew Gam Pubuduwa’ disseminates climate smart home gardening techniques, where women farmers receive sprinkler and drip irrigation systems, seeds and fertilizers, as well as training on water management methods. This study draws on a feminist political ecology framework to analyze the experiences of women home gardeners who …

Digital (Re)Production: Spatial Mediations Through Augmented Reality Landscapes In ‘Pokemon Go’, Brigitte Pulminar Perkins

Theses and Dissertations--Geography

Since 2016, the mobile augmented reality game Pokémon GO has renewed interest within communities by mediating spatial engagement using in-game markers that must be engaged with throughout physical urban landscapes. This thesis identifies factors that influence the spatial distribution of digital markers used by this game to help inform analyses of urban gamification, urban spatial distribution, and cultural knowledge production processes. Drawing specifically on theories of urban spatialization and digital media studies, I highlight features of physical and digital legacies of redlining within Lexington, KY that are reproduced via Pokémon GO. I argue that the urban racialized landscape of Lexington …

State Governance And Less-Skilled Migrant Workers In South Korea, Weejun Park

Theses and Dissertations--Geography

This dissertation examines the migration governance of South Korea with a focus on the immigration of less-skilled migrant workers. While geographers and broader social scientists have explored this topic, previous studies have two main foci: 1) individual immigrants and their activities; and 2) migration policy development. Despite these studies’ contribution to the scholarship, there seems to be a relative lack of interest in the South Korean state as a potentially crucial actor in governing less-skilled migrant workers. To address this gap, this dissertation draws upon (political) geography, related social sciences, and interdisciplinary fields such as border studies, migration studies, and …

Presenting Past People: Storytelling Through Prehistoric Garment Reconstructions, Floor Huisman, Anna Zimmermann, Ronja Lau, Karina Grömer

Textile Crossroads: Exploring European Clothing, Identity, and Culture across Millennia

This paper argues that we need to focus on past people (rather than just objects) in our narratives and museum displays to engage museum visitors more effectively. It will demonstrate that we can use a combination of well-researched physical and digital prehistoric garment reconstructions to implement more people-centered approaches also used in living history, which bring the past to life and allow visitors to literally come face-to-face with long-dead people. In this way, visitors can relate to past people on an emotional level, which helps them to learn much more about past life than many traditional displays. After outlining how …

Technical And Technological Analyses Of Excavated Textiles, Christina Margariti, Judith Goris, Petra Linscheid, Agata Ulanowska

Textile Crossroads: Exploring European Clothing, Identity, and Culture across Millennia

Textiles are particularly complex and labor-intensive structures, thus their constructive elements, such as fibers and yarns, as well as the final textile products (e.g., threads, cords, fabrics, and applied decoration) reveal a range of important technical, technological, and sociocultural information. In this paper, we discuss the analysis of excavated textiles at two levels:

1) Technical analysis that offers basic information about the qualities of examined textile samples.

2) Technological analysis that provides insights into technology, social relations of production, and the level of craft specialization or production modes.

Both analyses offer new evidence for environmental resources, sustainability, trade, and exchange, …

Investigating Organic Colorants Across Time: Interdisciplinary Insights Into The Use Of Madder, Indigo/Woad, And Weld In Historical Written Sources, Archaeological Textiles, And Ancient Polychromy, Paula Nabais, Cecilie Brøns, Magdalena M. Wozniak

Textile Crossroads: Exploring European Clothing, Identity, and Culture across Millennia

Organic dyes have been used from the earliest times to provide color primarily to textiles, but also as a colorant in painting. Such organic dyes could create a wealth of colors, depending on the availability and know-how of resources. These dyes are usually organic in nature, and primarily obtained from different plant sources. Unfortunately, the characterization of natural organic colorants in textiles and artworks is still a challenge. The difficulty of analyzing these materials is sometimes allied to the frequent impossibility of micro-sampling, and the frailty of the objects. Many techniques, such as HPLC (High-Performance Liquid Chromatography) and SERS (Surface-Enhanced …

Towards Textile Narratives: A Cross-Over Perspective On Textile Imagery In Statuary, Iconography, And Literature, Leyre Morgado-Roncal, Juliane Müller, Marisa Kerbizi

Textile Crossroads: Exploring European Clothing, Identity, and Culture across Millennia

Textiles and clothing constitute a fundamental element of our cultural past, present, and future. Therefore, they were also represented in many mediums, such as iconographic depictions and literature. Images are a source of visual and mental illustration and are often dependent on the viewer’s perspective. As a result, the representations of textiles convey social constructions and their cultural perception. Their study is the focal point of this article: The ways in which textiles and clothing are described by the imagery shown in Greek and Roman statuary and iconography, as well as in contemporary Albanian literature and mythology.

Representations illustrate the …

Young Romans: Status, Dress, And Gender, Mary Harlow, Lena Larsson Lovén

Textile Crossroads: Exploring European Clothing, Identity, and Culture across Millennia

The demographics of the Roman world suggest that it was a world full of children. Demographers argue that in order simply to maintain population levels in a period where life expectancy was very short by modern standards, and infant mortality high, a woman should, on average, have six children, on the assumption that not all would live to adulthood. Despite much research in the last fifty years, children still remain partly invisible in the Roman world. This is primarily because they leave little evidence produced by themselves and are seen through the prism of adult eyes. Inevitably, given the nature …

Narrative And Material Tools Of Resistance: Mobilizing Textile Crafts, Heritage, And Fashion In The Context Of The Invasion Of Ukraine (2022–2023), Magali-An Berthon, Sophia Hayda, Tetiana Krupa, Yuliia Lazorenko, Marie-Louise Nosch

Textile Crossroads: Exploring European Clothing, Identity, and Culture across Millennia

In 2022–2024, textile and fashion scholars came together to write an anthology sharing a new vision of European history as seen through textiles, in the COST Action EuroWeb. During this period, the continent was still dealing with the consequences of the COVID-19 pandemic and was then faced with Russia’s full-scale invasion of Ukraine in February 2022. Contemporary European history will be markedly defined by the ongoing war in Ukraine. One remarkable aspect of this conflict is the way textiles and dress appear daily in a variety of media outlets, mobilized as visual and semiotic means to communicate issues of war …

A Sensory Perspective On High-Ranked Women’S Dress In The 8th To 4th Century Bc In The Mediterranean And Central Europe, Karina Grömer, Susanna Harris, Audrey Gouy, Cecilie Brøns

Textile Crossroads: Exploring European Clothing, Identity, and Culture across Millennia

In the late 20th century, the study of western science was dominated by a philosophical approach to evidence as text and meaning. In archaeology, material culture was treated like text, to be read through systems of signs, symbols, and indices put together in syntax. For studies of dress, this was influential in understanding dress as a cognitive system compiled to create identities and meaning. In this approach, textiles, fastenings, hairstyles, and gestures are presented as signs and symbols used to form a statement about identity, to be read by others. There was a focus on the visuality of dress and …

Background: Six Homo naledi early juveniles were recovered from U.W. 101 (Dinaledi Chamber), U.W. 102 (Lesedi Chamber), and U.W. 110 in the Rising Star cave system. Aim: This paper develops the information for the H. naledi early juvenile life stage, as defined by a combination of deciduous and permanent dentition, and the eruption of the first permanent molar. Subjects and methods: The growing number of young individuals recovered from the Rising Star cave system allows us to gain a better understanding of their variation, or lack thereof, and provides a basis to estimate broad ranges for age at death of …

Human–Environment Interactions At Ta’Ab Nuk Na, A Submerged Maya Salt Works Site In Belize, Cheryl M. Foster, Heather Mckillop, E. Cory Sills

Faculty Publications

Sea-level rise and settlement are investigated at Ta’ab Nuk Na, an ancient Maya salt works in Belize, by examining samples from wooden posts and marine sediment. The samples included Post 145 of Building B and the Nunavut beam, along with marine sediment columns cut from beside both wooden posts. The sediment columns were sampled at 2 cm intervals. Loss-on ignition confirmed the presence of organic material. Identifying the organic content involved removing nonorganic material from the sediment and sorting the organic material under magnification. This procedure established that most of the organic material was red mangrove (Rhizophora mangle). Red mangroves …

Flooded Mangrove Landscapes Hide Ancient Maya Coastal Sites In Belize, Heather I. Mckillop

Faculty Publications

Evidence of ancient Maya exploitation of salt, other marine resources, settlement, and sea trade is hidden in flooded mangrove landscapes on the cays, mainland, and in shallow offshore locations on the south coast of Belize. This article includes a discussion of the coastal economy from the Middle Preclassic through the Postclassic periods (600 B.C.–A.D. 1500). Data from sites discovered and excavated since 1982 in the coastal area of the Port Honduras and Paynes Creek National Park support a model of coastal reliance on marine resources and tree crops. The need for a regular supply of coastal salt to inland cities …

Dpal-Bert: A Faster And Lighter Question Answering Model, Lirong Yin, Lei Wang, Zhuohang Cai, Siyu Lu, Ruiyang Wang, Ahmed Alsanad, Salman A. Alqahtani, Xiaobing Chen, Zhengtong Yin, Xiaolu Li, Wenfeng Zheng

Faculty Publications

Recent advancements in natural language processing have given rise to numerous pre-training language models in question-answering systems. However, with the constant evolution of algorithms, data, and computing power, the increasing size and complexity of these models have led to increased training costs and reduced efficiency. This study aims to minimize the inference time of such models while maintaining computational performance. It also proposes a novel Distillation model for PAL-BERT (DPAL-BERT), specifically, employs knowledge distillation, using the PAL-BERT model as the teacher model to train two student models: DPAL-BERT-Bi and DPAL-BERT-C. This research enhances the dataset through techniques such as masking, …

Convolution-Transformer For Image Feature Extraction, Lirong Yin, Lei Wang, Siyu Lu, Ruiyang Wang, Youshuai Yang, Bo Yang, Shan Liu, Ahmed Alsanad, Salman A. Alqahtani, Zhengtong Yin, Xiaolu Li, Xiaobing Chen, Wenfeng Zheng

Faculty Publications

This study addresses the limitations of Transformer models in image feature extraction, particularly their lack of inductive bias for visual structures. Compared to Convolutional Neural Networks (CNNs), the Transformers are more sensitive to different hyperparameters of optimizers, which leads to a lack of stability and slow convergence. To tackle these challenges, we propose the Convolution-based Efficient Transformer Image Feature Extraction Network (CEFormer) as an enhancement of the Transformer architecture. Our model incorporates E-Attention, depthwise separable convolution, and dilated convolution to introduce crucial inductive biases, such as translation invariance, locality, and scale invariance, into the Transformer framework. Additionally, we implement a …

Afbnet: A Lightweight Adaptive Feature Fusion Module For Super-Resolution Algorithms, Lirong Yin, Lei Wang, Siyu Lu, Ruiyang Wang, Haitao Ren, Ahmed Alsanad, Salman A. Alqahtani, Zhengtong Yin, Xiaolu Li, Wenfeng Zheng

Faculty Publications

At present, super-resolution algorithms are employed to tackle the challenge of low image resolution, but it is difficult to extract differentiated feature details based on various inputs, resulting in poor generalization ability. Given this situation, this study first analyzes the features of some feature extraction modules of the current super-resolution algorithm and then proposes an adaptive feature fusion block (AFB) for feature extraction. This module mainly comprises dynamic convolution, attention mechanism, and pixel-based gating mechanism. Combined with dynamic convolution with scale information, the network can extract more differentiated feature information. The introduction of a channel spatial attention mechanism combined with …
