Splitting Quintiles: Exploring The Relationship Between Income Inequality And Political Participation In The American Electorate, Laura E. Kaehler

LSU Doctoral Dissertations

The connection between economic inequality and unequal democratic engagement has inspired an enduring vein of interest since academic antiquity. Research suggests income inequality has a negative effect on political participation, yet a question remains among the American electorate: Do individuals across income groups share economic insecurities from increasing inequality or do distinct groups democratically disengage?

To empirically investigate, I consider the context of election salience and the contingent role that voter turnout misreporting or “faux-voters” play in this relationship. I dissect the “rich” verses “poor” distinction into five income groups to explore electoral motivations and malaise of middle-income individuals and …

The Full Range Leadership Model (Frlm): Department Head Perceptions Of Leadership Style And Development, Stephanie Elaine Heroman

LSU Doctoral Dissertations

The purpose of this study is to discover the perceived leadership styles of department heads as categorized by the Full Range Leadership Model (FRLM), developed by Avolio and Bass (1991). The FRLM categorizes leadership style along a continuum, from laissez-faire leadership, to transactional leadership, and ultimately transformational leadership. Even though department heads occupy a pivotal leadership role, many do not have formal leadership training, and instead rise to power through disciplinary expertise. This study will collect data on the experiences contributing to the development of leadership style in department heads. Understanding the leadership styles and experiences of department heads will …

Using Phylogenetics And Floral Evolution Of Sicklebill Hummingbird-Pollinated Centropogon Subgenus Centropogon To Support Undergraduate Research, Janet Mansaray

LSU Doctoral Dissertations

The genus Centropogon subgenus Centropogon, offers an ideal system for studying macroevolutionary patterns due to its diverse floral morphologies and specialized pollinator interactions. This subgenus comprises 55 species, mostly found in mid-elevation Andean forests, where many species exhibit abruptly curved flowers, often associated with pollination by sicklebill hummingbirds. Using phylogenomic approaches, we conducted the first densely sampled analysis of this group, confirming the monophyly of two sections. Our study highlighted extensive gene tree discordance, likely driven by incomplete lineage sorting. Floral curvature and inflorescence structure evolved in a correlated fashion, leading to multiple independent losses of traits linked to …

The Impact Of Outdoor Youth Education: An Examination Of The Social, Personal, And Environmental Developmental Outcomes Experienced By Youth At A Residential 4-H Summer Camp, Adam M. O'Malley

LSU Doctoral Dissertations

One of the most innovative ways that 4-H has fostered agricultural innovation and hands-on, experiential education has been through the development of youth outdoor education programs, more commonly known as 4-H Camp. State 4-H Camps and national camping events, including the inaugural National 4-H Conference, emerged following the establishment of localized county club camps. Three years after establishing the first 4-H Camp, more than 1,700 had emerged across the U.S., with early attendance exceeding 100,000 youth participants.

As a direct result of these early successes, the 4-H Camping movement has become celebrated as a novel technique to motivate youth to …

Indirect Effects And Context Dependency In Stream Fish Invasions, William K. Annis, Lily M. Thompson, Stephen R. Midway, Julian D. Olden, Brandon K. Peoples

Faculty Publications

Aim: Invasion ecology is replete with a body of well-supported yet contradictory evidence for numerous invasion hypotheses, likely as a result of context dependency. Context dependency in invasion studies can arise in two ways: (1) apparent, when results differ between studies solely due to methodical differences, or (2) mechanistic, when results truly differ due to ecological processes. One form of apparent context dependency occurs when causally linked factors associated with invasion success (hereafter, invasion drivers) either mask or enhance each other's effect on invasion success. Mechanistic context dependency can occur when regional scale processes modify the influence of local scale …

Real-estate websites make it easy to find and access information about a home. Information on property value, square footage, number of rooms, quality of schools, crime rates, and more is readily available. Some of these platforms have begun integrating climate-related risks in generic ways. However, this information provides limited if any actionable value and is unlikely to guide people’s decision-making on buying or renting a home, deciding where to vacation, or investing in a property. Making residents aware of the natural hazard risks to which their homes may be exposed is an important component of making communities more resilient. Both …

Can Americans’ Trust In Local News Be Trusted? The Emergence, Sources, And Implications Of The Local News Trust Advantage, Erik Peterson, Joshua P. Darr, Maxwell B. Allamong, Michael Henderson

Faculty Publications

Despite eroding consensus about credible political news sources, much of the public still trusts local media. We assess the emergence, sources, and implications of the trust advantage local news holds over national media. We argue the public now uses a news outlet's local orientation as a shortcut to assess its credibility. In survey experiments, we find unfamiliar news outlets are trusted more when they have a local cue in their name. In surveys where people evaluate digital sources covering their community, this heuristic leads the public to trust unreliable information providers that signal a local focus more than high-quality sources …

Beyond Reoffending And Rearrest: Expanding The Collateral Consequences Of Formal Processing To Youth Homelessness, Natasha Chlebuch, Jennifer Paruk, Caitlin Cavanagh, Paul J. Frick, Laurence Steinberg, Elizabeth Cauffman

Faculty Publications

There is robust evidence that juvenile justice contact during formative years is associated with deleterious outcomes. The effect of juvenile court intervention on youth homelessness, however, has received scant empirical attention despite evidence that many justice-involved youth are represented in the unhoused youth and adult population. This study leverages data collected from the Crossroads Study (N = 1115), a longitudinal, multi-site study to explore the impact of formal processing on subsequent experiences with homelessness. This study found that even when accounting for the effect of detention and other factors associated with youth homelessness, youth who were formally processed were twice …

Faculty Publications

US and EU flood mitigation policy both incorporate considerations of costs and benefits, and in recent years have taken steps to encourage accounting for positive and negative effects on vulnerable populations, broader non-market environmental impacts, and downstream effects beyond the target area of projects of flood mitigation projects. This work highlights the extent to which previous academic flood mitigation Benefit-Cost Analyses (BCA) papers have comprehensively considered such project effects. We do so through a systematic, PRISMA-style, review of BCA literature in the broader field of flood hazard mitigation and resilience decision-making. Our results suggest 1) most projects focus on monetizing …

Coupling Between Bacterial Phylogenetic Diversity And Heterotrophic Productivity In A Coastal Ecosystem Affected By Estuarine Plumes, Yao Liu, Shujie Cai, Wenxin Fan, Wupeng Xiao, Xin Liu, Edward A. Laws, Bangqin Huang

Faculty Publications

Understanding the diversity-productivity relationship (DPR) is crucial for elucidating the ecological functions of marine bacterioplankton. However, studies have often focused on species diversity, neglecting phylogenetic diversity, which may offer deeper insights into the complex ecological processes shaping DPR in natural systems. This study addressed this gap by exploring the role of phylogenetic diversity in bacterioplankton productivity in the northern South China Sea, a coastal ecosystem influenced by estuarine plumes. We aimed to disentangle the mechanisms driving DPR and investigate how estuarine plumes modulate these processes. Our results show that the substantial enhancement of phytoplankton production by the Pearl River plume …
