Course Correction: Navigating Equity In Ninth-Grade Advanced Placement, Sarah R. Morris, Sarah C. Mckenzie, Miranda Vernon

Education Reform Faculty and Graduate Students Publications

This robust mixed-methods study examines ninth-grade advanced course placement in Arkansas, revealing disparities rooted in race and socioeconomic status. Utilizing a logit analysis for a five-year pooled sample (n=163,616), we find persistent enrollment gaps for Black ninth-grade students after controlling for prior academic achievement, highlighting systemic barriers to access to advanced courses. Socioeconomic divides are also evident in our analysis. Qualitative findings from counselor interviews highlight the importance of parental involvement in course placement decisions, particularly for students from lower socioeconomic backgrounds. Overall, we find through these interviews that districts consider a myriad of factors when considering course placement for …

Research Outputs: 2025-Present

Myopia is becoming increasingly common in young generations all over the world, and it is predicted to become the most common cause of blindness and visual impairment in later life in the near future. Because myopia can cause serious complications and vision loss, it is critical to create and prescribe effective myopia treatment solutions that can help prevent or delay the onset and progression of myopia. The scientific understanding of myopia's causes, genetic background, environmental conditions, and various management techniques, including therapies to prevent or postpone its development and slow its progression, is rapidly expanding. However, some significant information gaps …

Prevalence Of Missed Opportunities For Immunization And Its Associated Factors Among Children Below Two Years Old Attending Primary Healthcare Centers In Baghdad/Al-Karkh, Baraka Safaa’ Mustafa, Jalil Ibrahim Saleh

Muthanna Medical Journal

Immunization is an effective means for preventing illness and reducing the burden of various infectious diseases. Incomplete or partial immunization poses a serious threat to the health of children in many developing countries, including Iraq. The objectives are to investigate the prevalence of missed opportunities for immunization (MOI) and its associated factors among children aged below two years old attending primary health care centers (PHCCs) in Baghdad/Al-Karkh. A cross-sectional study involving 500 children’s companions attending PHCCs in Baghdad/Al-Karkh from the 1st of September 2022 to the 1st of July 2023. The respondents were enrolled using a systematic random sample technique …

Paleoclimate Of The Peruvian Andean Highlands During The Late Holocene, Jarunetr Sae-Lim

Arts & Sciences Graduate Student Theses and Dissertations

The tropical and central Andean highlands (>4,000 m above sea level) supply critical freshwater resources to the Amazon Basin, supporting large communities in mountain regions and lowlands. Due to the scarcity of historical weather data spatially and temporally, it is challenging to quantify hydroclimate and environmental responses to anthropogenic climate change. Paleoclimate reconstruction and modeling can provide critical insights into key hydroclimate processes and how hydroclimate in this region has responded to climate change and variability through time. However, biomarker-based paleoclimate proxy reconstructions are still very rare in this region. This dissertation quantifies local-scale and regional-scale hydroclimate and environmental …

Each community offers innovative solutions drawing on their Indigenous knowledge to overcome water supply challenges. Communities with more resources are better equipped to cope with water insecurity and environmental degradation.

In The Hot Seat: Acquiring Kernel Density Heat Map Design Guidance Through Delphi And Survey Methods, Lauren Eileen Mckinney-Wise

Dissertations and Theses

Kernel density heat maps have emerged as a new, popular thematic map type. Yet, unlike other thematic map types, little if any published guidance exists for effective heat map design. This is significant because maps are highly persuasive objects that are often utilized to communicate important information, but maps can also be misleading and misunderstood. Therefore, proper guidance for heat map creation is critical for cartographers to create maps that convey geographic information successfully.

To address this literature gap, I used a modified Delphi method and an online survey to investigate several questions, including understanding what cartographic experts think are …

The Implementation Of Trauma Informed Design In The United States Prison Campus: A Standardized Design Methodology, Quille A. Hughes

Theses

The concept of spaces for punishment has been a topic of conversation for centuries. Only now are members of the community touching the surface of concepts that rewrite the methodology behind the design of these spaces in the hopes of providing a different outcome: rehabilitation. Trauma-Informed Design as a concept is in its infancy, and therefore requires decades of research into the effects of its installation; there is no greater need for this consideration than in the United States criminal justice institution. This thesis will not attempt to cover the changes necessary to United States prison policy. It will instead …

Coastal Wetland Restoration Through The Lens Of Odum's Theory Of Ecosystem Development, Friedrich W. Keppeler, Annette S. Engel, Linda M. Hooper-Bùi, Paola C. López-Duarte, Charles W. Martin, Jill A. Olin, Katelyn J. Lamb, Michael J. Polito, Nancy N. Rabalais, Brian J. Roberts, Erick M. Swenson, Olaf P. Jensen

Michigan Tech Publications

Advancing ecological restoration assessments requires a more detailed consideration of species interactions and ecosystem processes. Most restoration projects rely on a few metrics not always directly linked with ecological theory. Here, we used Odum's theory of ecosystem development to assess and compare the ecosystem structure and services of created marshes (4–6 years old) with preexisting, reference marshes in a brackish water region of the Mississippi River Delta. We built ecosystem models for created and reference marshes that integrated large datasets of stomach contents, stable isotopes, and taxa abundances. Despite strong resemblance in community structure, created marshes were at an earlier …
