The Effects Of Clothing Size On Self-Esteem Regarding Gender, Cailin Mahoney

Perspectives

Recently there has been a sufficient amount of literature regarding how clothing size affects the self-esteem of each gender in a variety of ways. The purpose of this literature review is to explore how standard clothing sizes affect the self-esteem of each gender, men and women, differently. The findings suggest a Eurocentric ideal that women are held to more of a thin ideal, while men are held to more of a muscular ideal. Additionally, when both women and men did not meet their expected ideals, it caused their self-esteem to become diminished. Overall, women cared more about the clothing size …

Social Media And Democracy, Seth C. Oranburg

Law Faculty Scholarship

[Excerpt] "Lately, people have been finding giant pet goldfish in lakes across America. You may see these tiny fish swimming in bowls at the county fair, but left alone in a lake or large pond, where they are dropped perhaps by a well-meaning child, they can grow to 20 pounds or more— and destroy ecosystems. The goldfish is a cautionary tale that has been told time and again in different forms, like Pandora’s box."

Comparing The Effects Of Body Image And Bmi On Women’S Romantic Relationships, Isabella Luca

Perspectives

This literature review explores the relationship of how excess weight affects women's romantic relationships. Romantic relationship success has been assessed through the measures of body image and BMI. These similar measures of excessive weight were compared to determine the best measure/method to represent the relationship between excess weight and women’s romantic relationships. The hypothesis stated that excessive weight (in terms of body image, and not BMI) would decrease the overall success of women’s romantic relationships. Findings throughout this literature review have concluded that women have higher social pressure to be thin, women feel excess weight stigma more and this can …

How Will God And The Church Fit Into The Metaverse?, Grace Rose

Comm-entary

In this paper, I tell a story about the argument over whether God and the Church will be part of our coming “metaverse.” While we can be pretty sure that the metaverse will be good for the full range of “congregations,” good, reasonable citizens disagree about whether the metaverse will be just a tool in God’s creation or whether the metaverse will move us past traditional notions of God. In this story, I introduce some of the characters who engage in and contribute to this argument. My story also animates some of the argumentative moves that these characters make.

Tiger King: A Case Study In Environmental Media Representation And Effects, Ashley White

Comm-entary

Over the past decades, tiger populations have drastically fallen worldwide to the point where most tigers are listed as endangered or critically endangered. Furthermore, there are currently more tigers living in captivity in the US than in the wild. In this paper, the relationship between the environmental issue of conservation and the effects of mass media productions is explored through a critical analysis of Tiger King. Specifically, the purpose of this paper is to answer the following questions. First, does Tiger King perpetuate or disrupt existing models of documentary narrative and cinematography? (Q1) Second, to what extent is Tiger King …

Equity Vs. Equality: How Differing Viewpoints Choose To Portray History, Sara Donatello

Comm-entary

This paper explores the themes of equity and equality, defining the terms and applying them to projects done by civil rights activists Nikole Hannah-Jones and Robert Woodson, and a government commission created by Donald Trump. The 1619 Project, founded by Hannah-Jones, pushes the narrative of equity, following the idea of the politics of difference. 1776 Unites, founded by Robert Woodson, provided a counterargument to the 1619 Project, and follows the politics of universalism and equality, holding everyone in the same esteem. Finally, the 1776 Commission, created by Donald Trump, is not associated with 1776 Unites but follows the same narrative …

The Resurrection Of Yik Yak, Lily Neher

Comm-entary

In this paper, I discuss the impact of the app Yik Yak on college campuses, after it returned as a platform in 2021 post 2017 removal. The key aspects of the app include its location-based nature, anonymity, and user moderation system. I discuss advantages and disadvantages of the culture that it fosters, as well as greater social, political, and philosophical implications of Yik Yak as a hybrid space, or a space that permits communication both online and in the real world.

Covid-19 Conversation Analysis, Luca Tosi

Comm-entary

In this paper, I present the findings from an empirical project completed for a college-level Communication Analysis class. These findings, while containing scholarly terms and nomenclature, are highly applicable to any day-to-day interactions had between any multitude of participants. It is my goal, throughout this paper, to provide readers with a more in-depth look at the ways in which our words and actions convey our messages in ways we didn’t even consciously mean.

The Impact Of Hurricanes On The Acoustic Detection Of Cetaceans, Aditi Tripathy

Master's Theses and Capstones

Passive acoustic monitoring (PAM) is valuable for understanding the presence, behavior, distribution, and population density of marine mammals. While long-term variability of ambient sound is typically evaluated, the impact of short-term variability due to episodic events has not been assessed until now. Hurricanes Dorian (Category 5; 2019), Florence (Category 4; 2018), and Humberto (Category 3; 2019) impacted the soundscape as observed from the passive acoustic data at the Atlantic Deepwater Ecosystem Observatory Network (ADEON) locations in the US Mid- and South Atlantic Outer Continental Shelf. Hurricanes are increasingly prevalent in the North Atlantic and increase the ambient sound level at …

The Effects Of Disorder In Van Der Waals Materials, Jake Riffle

Doctoral Dissertations

Due to their two-dimensional structure and wide range of electronic behaviors, van derWaals materials have garnered a lot of attention for new technological applications. However, much is still unknown about the consequences that impurities and disorder have on the performance of many new van der Waals materials. In my research I use scanning tunneling microscopy(STM) and electronic transport techniques to study the different types of disorder in three common van der Waals materials: tantalum disulfide (TaS2), black phosphorus (BP), and two-dimensional graphene. In TaS2 I show a sample preparation dependence on the surface state of the bulk crystal and emphasize …

I. Incorporation Of Functionality At The Β-Position For The Zinc-Mediated Chain Extension Reaction Ii. Formal Synthesis Of Heliotridane And Pseudoheliotridane Through A Zinc-Mediated Chain Extension Approach, Nicholas Alexander Arnista

Doctoral Dissertations

The zinc-mediated chain extension reaction has been previously developed to incorporate alkyl or aryl substituents at the β position of the chain-extended product. The incorporation of heteroatom functionality at the β position of the chain-extended product was demonstrated through the use of a functionalized zinc carbenoid species. Silyl ether-functionalized geminal diiodides were used in the chain extension reaction with low to modest yields. Optimization of the chain extension reaction was performed by modification of solvent, reaction temperature, reaction time, and addition of diiodide. The chain extension reaction was performed on several different substrates, such as β-keto esters, β-keto amides, and …

Primary Cilia In The Pathogenic Mouse Brain & Eeg Waveform Analysis Of A Mouse Model Of Alzheimer's Disease, Ashley Diemand Sterpka

Doctoral Dissertations

In the last two decades, primary cilia have become recognized as tiny sensory organelles with considerable physiological function including regulation of cell division and modulation of transduction pathways. Scientists build on former discoveries, identifying new connections and accentuating the value of primary cilia in disease and intercellular signaling. Astrocytes, the most numerous cell type within the brain, act in support of neurons and maintain neurological health by providing neurotrophic factors and removing synaptic debris. These cells are particularly significant in reparations following neural injury and diseases, altering shape and function to protect healthy tissue. Astrocytes display primary cilia, yet little …

Climatic And Biotic Interactions In Terrestrial Systems During Ancient Warm Periods, Sarah Johnson Widlansky

Doctoral Dissertations

This work focuses on two terrestrial sedimentary records in the western United States that record the ancient greenhouse interval of the early Paleogene (~ 55 million years ago). The Paleogene, and past warm periods in general, offer a means of understanding potential biotic and environmental response to future warming scenarios. Part One of this dissertation establishes a new stable isotope climate record from the Bighorn Basin of Wyoming that is tied to an extensive fossil mammal assemblage (Chapter 1). This new stable isotope record captures carbon isotope excursions (CIEs) associated with the early Eocene hyperthermals ETM2, H2, and potentially I1 …

Heat Transport By Baroclinic Acoustic Streaming, Jacques Abdul Massih

Doctoral Dissertations

Acoustic streaming refers to time-averaged flows generated by time-periodic sound waves. In classic“Rayleigh streaming”, the mean flow is generated by the interaction of a standing acoustic wave with a solid boundary (e.g., a channel wall). Applications of acoustic streaming include inducing fluid mixing in microfluidic medical devices, improving the efficiency of chemical reactions, and enhancing heat transfer. Recently, Chini et al. [J. Fluid Mech., Vol. 744 (2014)] and Michel & Chini [J. Fluid Mech., Vol. 858 (2019)] demonstrated that strong acoustic streaming flows can be generated in gases subjected to an imposed cross-channel temperature gradient. In contrast with Rayleigh streaming, …

First-Generation Student Status As A Predictor Of Participation In Selected High-Impact Practices At The University Of New Hampshire, Paula Marie Dinardo

Doctoral Dissertations

Institutions of higher education are under increased scrutiny as graduation rates decline while student loan debt soars. One proposed strategy to improve completion rates is to give additional support to those students who are most at-risk of leaving college before graduating. Research has shown that first-generation students are more likely to leave college before attaining a degree than their non-first-generation counterparts.

Research has also suggested that engaging in two or more High-Impact Practices (or HIPs) during college can improve one’s academic achievement and persistence to graduation. HIPs are defined as educationally purposeful activities that require students to delve deeply into …

Penalized Regression Splines-Based Tests For Comparing Two Time Series With Unequal Lengths, Mirajul Islam

Doctoral Dissertations

The Spline-based modeling has been an established tool for parametric and nonparametricregression modeling because of its continuous progress on theoretical and computational fronts over the last three decades. This thesis explores the idea of penalized spline modeling and goodness of fit testing in the context of time series testing in the frequency domain approach. The comparison of different time series is an important topic in statistical data analysis and has various applications in scientific research. One approach to identifying similarities or dissimilarities between two stationary processes is to compare the spectral densities of both time series. This thesis examines whether …

Efficient Data-Driven Robust Policies For Reinforcement Learning, Bahram Behzadian

Doctoral Dissertations

Applying the reinforcement learning methodology to domains that involve risky decisions like medicine or robotics requires high confidence in the performance of a policy before its deployment. Markov Decision Processes (MDPs) have served as a well-established model in reinforcement learning (RL). An MDP model assumes that the exact transitional probabilities and rewards are available. However, in most cases, these parameters are unknown and are typically estimated from data, which are inherently prone to errors. Consequently, due to such statistical errors, the resulting computed policy's actual performance is often different from the designer's expectation. In this context, practitioners can either be …

N-Heterocyclic Carbene Functionalized Single-Chain Nanopartcles Aqueous Catalytic Platform, Xianggeng Liu

Doctoral Dissertations

Single-chain nanoparticles (SCNP) are a class of intramolecular cross-linked polymericnanoparticles with a variety of applications including catalysis, sensors, nanomedicine, and nanoreactors. Such nanoparticles are synthesized by folding or collapsing single polymer molecules. By implementing a single-chain folding technique, the single-chain nanoparticles with uniform degrees of cross-linking are synthesized by parent polymer chains with similar chain lengths and polymer microstructure. Polymer chains that are synthesized by various controlled polymerization techniques can be converted to SCNPs through a variety of covalent chemistry and supramolecular interactions. Based on the expected cross-linking chemistry, related functional groups can be installed either during monomer synthesis or …

Recombination Drives Genomic Divergence And Cooperation Across Bacterial Populations, Isaiah Paolo Atienza Lee

Doctoral Dissertations

Genetic recombination is a major driving evolutionary force across the Tree of Life, but it plays a special role in bacteria. In the absence of sexual reproduction, bacteria rely on horizontal transmission to recombine their genetic material. Horizontally transferred genes can spread rapidly across a population, greatly expanding the niches available to bacteria. We are only beginning to understand the degree to which recombination varies between and even within bacterial taxa. In the first part of this dissertation (Chapter 1 and Chapter 2), I investigate how patterns of recombination influence bacterial diversity. In Chapter 1, I studied the pan-genome of …

Sociocultural Dimensions Of Environmental Stewardship In New Hampshire: Implications For Adult Environmental Education, Ian Patrick Hanley

Doctoral Dissertations

The overarching aim of this dissertation is to expand evidence and theory of adult identity processes in the context of environmental stewardship, as well as to provide knowledge and recommendations to environmental stewardship and environmental education professionals. The intent is to better understand variation in how adult environmental stewards report on and value their own engagement with both sociocultural and natural systems. This line of inquiry stems from the fundamental claim that environmental stewardship activity is not singularly based on environmental content knowledge but is also related to forms of cultural and social engagement. By recognizing these dual aspects of …

Socioscientific Decision-Making In Undergraduate Students: The Role Of Personal Epistemology, Jordan Dana Bader

Doctoral Dissertations

Socioscientific issues (SSIs), or controversial scientific issues with social implications, influence members of society regardless of demographic. SSIs are contentious and ill-structured, meaning they do not have a definitive answer. To properly equip students with the tools needed to handle SSIs, undergraduate science curricula emphasize scientific literacy skills, such as the ability to search, recognize, and utilize accurate scientific information when handling science driven issues outside of the classroom. However, SSIs are influenced by political, social, economic, and cultural stakeholders. Therefore, students may not be basing their SSI decisions off of accurate information. An individual’s personal epistemology is known to …

Water Droplet Machining And Droplet Impact Mechanics, Benjamin Mitchell

Doctoral Dissertations

Water Droplet Machining (WDM) is a new manufacturing process, which uses a series of high-velocity, pure-water droplets to impact and erode metal workpieces, for the purpose of through-cutting, milling and surface profiling. The process is conducted within a vacuum environment to suppress aerodynamic drag and atomization of the waterjet and droplet stream. This preserves droplet momentum and allows for a more efficient transfer of energy between the water and workpiece, than in standard atmospheric pressure. As a new manufacturing technique, parameter-specific details and characteristics of this process are absent from the scientific literature. Furthermore, the erosion mechanisms involved in droplet-solid …

Structural And Biochemical Characterization Of The Allosteric Regulation Of Photoreceptor Phosphodiesterase, Richa Garg

Doctoral Dissertations

ABSTRACT

Structural and Biochemical Characterization of the Allosteric Regulation of Photoreceptor Phosphodiesteraseby Richa Garg

The photoreceptor phosphodiesterase (PDE6) is the central enzyme in the visual signaling pathway. Cone PDE6 is a homodimer consisting of a catalytic dimer (Pα’α’) and two cone-specific inhibitory γ-subunits (Pγ’). Rod PDE6 is a heterotetramer which consists of a catalytic dimer (Pαβ) with two rod-specific Pγ subunits. The PDE6 differs from other phosphodiesterases (PDEs), in its unique inhibitory Pγ subunit and its activation by α-subunit of the G-protein (Gα). Regulation of PDE6 activity is a key factor in determining the electric response upon light stimulations. PDE6 …

Melanin Pigments As Antibacterial Agents, Tahmineh Rahmani Eliato

Doctoral Dissertations

In this dissertation I investigated the structural properties of melanin biopigment from different sources as an antibacterial and endotoxin bonding agent. I extracted melanin from Equus ferus hair with acid hydrolysis (termed EquusMel) and characterized it by microscopic and spectroscopic techniques. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed that EquusMel is mainly elliptical in shape with a mesoporous and layered structure within the individual particles. Wide-angle (WAXS) and small-angle (SAXS) X-ray scattering measurements demonstrated a semicrystalline multilayered structure with order spacing of 45.2 Å. Pore size distribution determined by the Barrett–Joyner–Halenda (BJH) method showed primary pores within …
