Directory Of Services And Resources To Support Breastfeeding Initiation, Exclusivity, And Longevity In The El Paso Texas Region, Tiffany Nichelle Butler

Open Access Theses & Dissertations

Human milk is recognized as the ideal food for infants; however, in order for human milk to get to the infants, breastfeeding requires the support of the healthcare system. Among infants born in 2015 in United States, 4 out of 5 started to breastfeed and despite of this high rate, only 22% of mothers exclusively breastfed for 6 months. The decisions to breastfeed are influenced by multiple factors including breastfeeding education and support, hospital practices, and participating in tailored education programs. The Office of the Surgeon General has identified the need for healthcare systems to "guarantee continuity of skilled support …

Cross-Language Sense Priming, Jennifer M. Blush

Open Access Theses & Dissertations

Research has yet to systematically examine the extent to which activation spreads across multiple senses of words. The two present experiments focused on examining the effects of cross-language sense priming via processing polysemous words in and out of a sentence context. In Experiment 1, participants made semantic verification of word pairs; critical trials contained polysemous words. In Experiment 2, participants read sentences in an eye-tracker with critical sentences containing both instantiations of a polysemous word. Results from both experiments suggested that senses can be primed within and across languages. These results give support for the DFM's interconnective network of conceptual …

The Battle Off The Battlefield: Exploring Medical Cannabis Use Among U.S. Veterans Looking For Relief, Viridiana Edwards

Open Access Theses & Dissertations

This study analyzed the reasons U.S. veterans use cannabis, focusing on what ways cannabis is socially acceptable, what ways it is viewed as deviant, and to what extent veterans are using cannabis for pain and/or mental relief. To answer these questions, an open and closed ended questionnaire was created and was available online. My results showed that U.S. veterans were using medical cannabis due to the negative side effects from the pharmaceutical medication that they were prescribed, physicians not listening to them during their appointments, and for social integration.

Patient Perception In Quality Of Health Care In Civilian And Military Hospitals, Rodolfo Gonzalez Garza

Open Access Theses & Dissertations

The purpose of this research is to examine and relate Erving Goffman's theory and concept of total institution to the perceived experienced quality of health care that occurs in the treatment of patients, in both preoperative and postoperative surgical procedures, at civilian and military hospitals. Goffman argues that there is a distinct relationship between the medical staff and patients at the hospitals. The staff most often feels superior and correct in their actions, while the patients perceive themselves as weak, inferior, and defenseless. In my thesis, I use a qualitative method approach to determine how veteran patients perceive their quality …

Angels And Sub-Divine Supernatural Beings: Their Characteristics, Function, And Relationship To God And Humanity In Deuteronomy-Kings, Joni Amanda Mcguire-Moushon

Dissertations

This research analyzes selected passages in Deuteronomy-Kings in order to determine the characteristics and roles of supernatural sub-divine beings within these books. Then this data is compared with the angelology of the Second Temple period in order to identify the similarities and the extent of the differences between them.

Deuteronomy contains references to supernatural sub-divine beings, such as “demons” and “holy one(s)”. While Deuteronomy affirms the existence of sub-divine beings, it forbids the Israelites to worship them. In the books of Joshua and Judges, there is awareness of supernatural beings and their roles as warriors, messengers, and tormentors. However, in …

Examining Perceptions Of Service Quality Of Student Services And Satisfaction Among International Students At Universities In Indiana And Michigan, Mordekai Ochieng Ongo

Dissertations

Problem

Universities in the United States face financial constraints, intense competition for students, declining student enrollment, and constant student attrition. However, an increasing number of international students seek higher education abroad, especially in the U.S. Providing quality services to these international students might help institutions attract and retain more of them. Unfortunately, little empirical research has been done on international students’ perceptions of service quality, especially of non-academic services. This study fills that gap by using a modified SERVPERF questionnaire to investigate international students perceived service quality and satisfaction at eight universities in Indiana and Michigan.

Graduate School of Oceanography Faculty Publications

Phytoplankton play a key role as the base of the marine food web and a crucial component in the Earth's carbon cycle. There have been a few regional studies that have utilized satellite‐estimated phytoplankton functional type products in conjunction with other environmental metrics. Here we expand to a global perspective and ask, what are the physical drivers of phytoplankton composition variability? Using a variety of satellite‐observed ocean color products and physical properties spanning 1997–2015, we characterize spatial and temporal variability in phytoplankton community size structure in relation to satellite‐based physical drivers. We consider the relationships globally and by major thermal …

Mothering The Aggressive Child, Katja Ermann

Antioch University Dissertations & Theses

This qualitative study explores the experience of mothers parenting significantly aggressive children, ages five to 10. Little has been known previously about how women experience this aggression or the social and psychological impacts it has on them. This dissertation highlights the women’s understandings to provide a solid basis for theoretical explication using a Constructivist Ground Theory approach. Significant findings include the invisibility and stigma the women feel and the ways in which the experience is similar and dissimilar to other forms of family violence, particularly adolescent-on-parent violence (APV). Differences were found in social stigma between women whose child has a …

Polyamorous Millenials In Therapy: Interpreting Experiences To Inform Care, Rebecca Calhoun-Shepard

Antioch University Dissertations & Theses

Polyamory (poly) refers to a way of loving involving multiple concurrent romantic relationships. It has been suggested that consensual non-monogamies are becoming increasingly visible, particularly in the millennial generation. This warrants exploration of cultural considerations and the unique needs of this population to inform care and minimize potential for harm. The present study used interpretative analysis to explore the phenomenon of polyamorous millennials in therapy as described across semi-structured interviews with therapists and poly clients. Three primary themes emerged from aggregate data, including Idiographic Experiences in Therapy, Therapy with Polyamorous Millennials, and information about Polyamory and Millennials beyond a therapy …

Helping Animals, Helping Ourselves: Reciprocal Benefits Of Prosocial Behaviors Directed Toward Animals, Casey A. Culligan

Antioch University Dissertations & Theses

This is a dissertation project on the reciprocal benefits—to volunteers and animals—of volunteering at animal shelters, rescues, and sanctuaries. I have provided a brief literature review on the relationship between prosociality and helper/recipient wellbeing, highlighting the current scarcity of research on the human enactment of prosocial behavior with animal recipients of help. I then further supported the need for continued research in this regard by examining the emerging body of research on the suggested wellbeing-benefits of human–animal interaction. An ecopsychological framework was utilized to emphasize the potential therapeutic affects (to both humans and animals) of engaging in prosocial behaviors directed …

Graduate School of Oceanography Faculty Publications

The Southern Ocean is in an era of significant change. Historic overharvesting of marine mammals and recent climatic warming have cascading impacts on resource availability and, in turn, ecosystem structure and function. We examined trophic responses of sympatric chinstrap (Pygoscelis antarctica) and gentoo (Pygoscelis papua) penguins to nearly 100 y of shared environmental change in the Antarctic Peninsula region using compound-specific stable isotope analyses of museum specimens. A century ago, gentoo penguins fed almost exclusively on low-trophic level prey, such as krill, during the peak of historic overexploitation of marine mammals, which was hypothesized to have …

Upper Ocean Distribution Of Glacial Meltwater In The Amundsen Sea, Antarctica, Louise C. Biddle, Brice Loose, Karen J. Heywood

Graduate School of Oceanography Faculty Publications

Pine Island Ice Shelf, in the Amundsen Sea, is losing mass due to increased heat transport by warm ocean water penetrating beneath the ice shelf and causing basal melt. Tracing this warm deep water and the resulting glacial meltwater can identify changes in melt rate and the regions most affected by the increased input of this freshwater. Here, optimum multiparameter analysis is used to deduce glacial meltwater fractions from independent water mass characteristics (standard hydrographic observations, noble gases, and oxygen isotopes), collected during a ship-based campaign in the eastern Amundsen Sea in February–March 2014. Noble gases (neon, argon, krypton, and …

Microstructure Evolution Of Chalcogenide Materials Via Molecular Dynamics, Sharmin Abdullah

Open Access Theses & Dissertations

The properties of a material are defined by its granular microstructure which is determined by its grain evolution and the types of grain boundaries present in the structure. For example, the performance of Cadmium Sulfide/Cadmium Telluride (CdS/CdTe) solar cells can be affected by the presence of grain boundaries which makes the study of grain structure evolution a very important part of solar cell performance optimization. Grain boundary mobilities are important properties in material science and engineering as they determine grain structures under given processing and operating conditions.

In this thesis, several computational tools were used to analyze the formation and …

Confidence Intervals For The Expected P-Value, Emmanuel Kofi Abrefa

Open Access Theses & Dissertations

The p-value is widely used in many application fields. In common practice, a scientific finding is deemed statistically significant if its resultant p-value is less than a pre-specified significance level, for example α = 0.05, albeit many statistically significant results are not reproducible in new studies. Mixed reasons including misuses, abuses, misunderstanding and misinterpretation arouse intensive debates and conservatives around the p-value from time to time over the years. Yet no reasonable solutions have been proposed. In this research, we make efforts to close the gap by advocating the use of confidence level for the expected p-value p0. This allows …

Electrical Engineering and Computer Science Faculty Publications

The high resolution of multidimensional space-time measurements and enormity of data readout counts in applications such as particle tracking in high-energy physics (HEP) is becoming nowadays a major challenge. In this work, we propose combining dimension reduction techniques with quantum information processing for application in domains that generate large volumes of data such as HEP. More specifically, we propose using quantum wavelet transform (QWT) to reduce the dimensionality of high spatial resolution data. The quantum wavelet transform takes advantage of the principles of quantum mechanics to achieve reductions in computation time while processing exponentially larger amount of information. We develop …

A Data-Driven Network Approach For Characterization Of Political Parties’ Ideology Dynamics, Josemar Faustino, Hugo Barbosa, Eraldo Ribeiro, Ronaldo Menezes

Electrical Engineering and Computer Science Faculty Publications

Political ideology is a major social phenomena that plays a crucial role in the formation and dynamics of ideologically-aligned social groups. This alignment gives rise to some of the most powerful social structures in modern democracies, the political parties. Due to the influence and importance of political parties in society, estimating their ideology is an active topic in political science research. However ideology is a very subjective phenomena and existing quantitative methods for ideology estimation are susceptible to a variety estimation issues, specially when applied in multi-partisan systems. In this work, we developed a data-driven network model for political ideology …

Towards Multiple Model Approach To Bridge Deterioration, Jin A. Collins

Open Access Theses & Dissertations

The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) marked the start of a new era in transportation in the United States. ISTEA required transportation agencies to take a proactive approach to planning and management of their assets. This included requirements for managing pavement, bridges, safety, congestion, public transportation, and intermodal systems. For horizontal transportation assets (i.e., bridges and pavement), deterioration modeling is an essential tool (Yanev and Chen 1993). Since ISTEA, Bridge Management Systems (BMS) have been utilized to inform decision-making regarding bridge projects such as maintenance, rehabilitation, and replacement (MR&R) under financial limitations (Agrawal, Kawaguchi, and Chen 2010). …

Comparative Study Of Analytical Models Of The Gruneisen Parameter Of Metals As Function Of Pressure, Celia Garcia Amparan

Open Access Theses & Dissertations

Commonly used Gruneisen parameter (γ) models only hold accurate in limited regimes making them inapplicable for use over wide temperature-pressure conditions. The accuracy of these analytical models of γ and of the thermal expansion of solids are of particular interest as these are considered proxies for quantifying anharmonicity, which may be a significant contribution to the thermal pressure at high temperatures. This work reviews various definitions of γ and their relations to the equations of state and apply them to two simple metals: Tantalum (Ta) and Copper (Cu), for which a high body of experimental data exists. Classical Molecular Dynamics …
