There is a growing trend to incorporate babies into yoga classes in an effort to increase the accessibility of postpartum exercise. There has been limited research conducted regarding the effectiveness of this emerging trend, and none have examined the feelings of participants engaged in mother and baby yoga classes. To address this gap in the literature, the …

Parent–Child Reciprocity? Parental Aggression And Oppositional Defiant Symptoms In Girls, Olivia J. Derella

Master's Theses

Objective. Evidence suggests that parents’ verbal aggression, corporal punishment, and inter-partner conflict are linked to children’s heightened conduct problems and oppositional defiant disorder (ODD). While children mutually influence parenting, strength of bidirectional relationships among these specific behaviors have been inconsistent across gender; further investigation is warranted to understand links between parental aggression and girls’ ODD symptoms. The current study tests independent reciprocal effects between specific forms of parental aggression and girls’ ODD dimensions of oppositionality, antagonism, and irritability. Method. Annual data from the longitudinal Pittsburgh Girls Study were used to evaluate parental aggression and girls’ ODD symptoms in a …

Pink And Dude Chefs: Efficacy Of An Online Train-The-Trainer Mechanism And Student Program Outcomes, Jacqueline Chen

Master's Theses

Background: The rate of overweight and obesity among adolescents aged 12-19 years has quadrupled since 1980. Reducing obesity is a key public health priority, as obesity is associated with individual and population-level health and economic consequences. Afterschool-based obesity prevention programs that aim to develop nutrition and culinary self-efficacy have shown promise. However, the level of aptitude among program instructors is directly correlated with student success, suggesting the importance of effective train-the-trainer (TTT) mechanisms for implementing and scaling up these strategies.

Pink and Dude Chefs (PDC) is an afterschool nutrition education and culinary skills program for middle-school adolescents aged between 11-14 …

The Recovery Of Protein From Egg Yolk Protein Extraction Granule Byproduct, Irene Jennifer Kaufman

Master's Theses

In addition to proving an excellent source of nutrients, eggs are used in the food, cosmetic, and biotechnology industries for their rheological and bioactive properties. Much of the potential for the added value is in individual components of the egg, rather than the whole egg. At low speed centrifugation, yolk separates into two distinct fractions—granules and plasma. It is becoming increasingly popular in the industry to remove the plasma fraction of the egg yolk to use for its livetins, particularly immunoglobulin Y, leaving behind a granule by-product (“yellow cake”). Previous research has shown potential added-value from the granule fraction, especially …

Mass Estimation Through Fusion Of Astrometric And Photometric Data Collection With Application To High Area-To-Mass Ratio Objects, Matthew Richardson

Master's Theses

This thesis work presents the formulation for a tool developed in MATLAB to determine the mass of a space object from the fusion of astrometric and photometric data. The application for such a tool is to better model the mass estimation method used for high area-to-mass ratio objects found in high altitude orbit regimes. Typically, the effect of solar radiation pressure is examined with angles observations to deduce area-to-mass ratio calculations for space objects since the area-to-mass ratio can greatly affect its orbital dynamics. On the other hand, photometric data is not sensitive to mass but is a function of …

"Ye Sons Of Mars": British Representations Of The Sudan Campaign In Print Culture, 1884–1899, Crystal E. Smith

Master's Theses

From 1884 to 1885 the British were first engaged with the Mahdist forces of Sudan in an effort to first rescue the inhabitants of Khartuom, and later to rescue the rescuer Charles “Chinese” Gordon. The affair played out both in Parliament and the newspapers as journalists became the cheerleaders for Empire. My thesis focuses on Britain’s 1884-1890 Sudan Campaign through print culture using political debates, journalism, literature, memoirs, and art. I show how the activism of the press and the romanticism of the larger media reinforced ideas about imperialism and the British role within the Empire at large.

Anaerobic Fermentation Of Food Waste And Glycerol To Hydrogen, Eric Robert Krikorian

Master's Theses

ABSTRACT

Anaerobic Fermentation of Food Waste and Glycerol to Hydrogen

Eric Krikorian

Hydrogen has several well-known advantages as a fuel and chemical feedstock, but current methods of hydrogen production are costly and energy intensive. A potentially advantageous source of hydrogen is fermentation of organic wastes, especially any abundant, low-cost wastes with a high content of simple sugars. Molar hydrogen yields from fermenters (aka digesters) are affected by pH, organic loading rate (OLR), hydraulic residence time (HRT), and substrate type. A less studied process to increase yield is sparging with low-H₂ content gas to strip H₂ from the digester …

The Population Genetics Of Morro Bay Eelgrass (Zostera Marina), Julia Gardner Harencar

Master's Theses

Seagrass populations are in decline worldwide. Zostera marina (eelgrass), one of California’s native seagrasses, is no exception to this trend. In the last 8 years, Morro Bay, California has lost 95% of its eelgrass. Eelgrass is an ecosystem engineer, providing important ecosystem services such as sediment stabilization, nutrient cycling, and nursery habitats for fish. The failure of recent restoration efforts necessitates a better understanding of the causes of eelgrass decline in this estuary. Previous research on eelgrass in California has demonstrated a link between population genetic diversity and eelgrass bed health, ecosystem functioning, and resilience to disturbance and extreme climatic …

The Rise Of The Maquiladoras And Crimes In Mexico, Christelle K. Bamona

Master's Theses

While it is generally argued that a stronger labor market is negatively associated with crime, there exists a “consensus of doubt” around the relationship between employment and crime. This paper examines the impact of the rise of female labor participation in manufacturing on various types of crimes in Mexico from 1998 to 2012. A fixed effects specification and an instrumental variable approach with regional and time fixed effects are employed to compare the crime rates in municipalities that were heavily exposed to local factory openings to municipalities that did not receive a labor shock of the same magnitude. By introducing …

Generating Prevalence Estimates Of Sensitive Behaviors Through List Randomization: Survey Experiment Among Indian Males, Abha Indurkar

Master's Theses

Survey respondents may under-report or misreport sensitive behaviors due to social desirability bias. List randomization is an indirect way of asking questions which allows respondents to answer sensitive questions without the surveyor knowing their actual response. This has emerged as a new technique to ask sensitive questions as it reduces respondent’s discomfort while reporting sensitive behaviors. In this study, we apply list randomization to generate prevalence estimates of sensitive behaviors and perception related to homosexuality, molestation of women and notion of partner purity in the sample of young, college educated Indian males. Our findings are consistent with the literature on …

Income Shocks And The Acceptance Of Intimate Partner Violence In Indonesia, Matthew N. Krupoff

Master's Theses

Intimate partner violence (IPV) is a pervasive issue affecting 1 in 3 women worldwide. Despite the negative welfare impacts, it is still seen as acceptable in some parts of the world, even amongst women. This paper examines how elastic these accepting attitudes towards IPV are to changing economic conditions. Specifically, this paper focuses on changes in intra-household resources from negative shocks to male-sourced income. The setting and context takes place in coastal communities in Indonesia, where fishing is a main source ofincome generated primarily by men. This paper uses satellite-derived fishing conditions to measure how women's attitudes towards IPV change …

La Madre Competitiva: An Experimental Study Of Women's Competitiveness In Medellin, Colombia, Miranda I. Lambert

Master's Theses

Abstract: This project is a follow up to Cassar, Wordofa, and Zhang (2015), which aimed at testing whether extending incentives beyond cash would alter the estimated competitive tendencies of men and women. Here we extend this work to an urban Colombian setting. In the previous study conducted in China, men have proven more competitive than women; however, once the incentive changes to a child-benefitting voucher, women increased their likeliness to compete. This research uses statistical and regression analysis to test whether or not women become more competitive when competing for a voucher, which directly benefits their child as opposed to …
