Survival In The Forest Understory: Resilience And Resistance To Damage In Native And Invasive Woody Plants, Elise Hinman

Dissertations - ALL

Non-native woody plants from Europe and East Asia have invaded intact, low-light forest understories in Eastern North America. Compared to co-occurring native species, invasive species exhibit greater productivity and resource use efficiency, but the extent to which plants are subject to tradeoffs between productivity and survival is unknown. Herbivory and freezing events are common sources of damage in the forest understory, and non-structural carbohydrates (NSCs) and defense compounds support resilience and resistance to damage. In this dissertation, I evaluated the hypothesis that invasive species maintain high productivity at the expense of storage and defense, reducing their survival under severe damage. …

“Is That Okay With You?”: Examining A Simulated Discussion About Accommodations Between University Students Identified As Having A Disability And A Standardized Faculty Member, Justin E. Freedman

Dissertations - ALL

Postsecondary students identified as having a disability in the United States are commonly expected to discuss the use of disability-related accommodations with faculty members. Researchers have previously used surveys and interviews to examine what students report about discussing accommodations with faculty members. However, little is known about how students advocate in the moment when communicating with faculty members about accommodations. In this study, I designed a clinical simulation to examine how 15 university students identified as having a disability engaged in and reflected upon a meeting with a standardized faculty member – an actor who I trained to communicate questions …

Putting Forts In Their Place: The Politics Of Defense In Antigua, 1670-1785, Christopher Kurt Waters

Dissertations - ALL

Between 1670 and 1785, the plantation elite on the British island of Antigua built and maintained at least fifty-four fortifications to protect the island from other European competitors. Rather than being commissioned, engineered, and defended by the metropolitan government in London, the defense of the island was the sole purview of the Antiguan legislature. Money, designs, and locations for these defensive sites came from internal deliberations on the island making them unique places to study iterations of seventeenth and eighteenth century British colonialism, elite thinking, and the impact on the landscape. To interpret these sites, I use archaeological, archival, and …

Deconvolution Of Membrane Protein-Detergent Complex Interactions, Aaron Wolfe

Dissertations - ALL

Membrane proteins are important in many biological functions such as cell-cell recognition, transport, and signaling; yet the study of these proteins is stunted due to their excessive aggregation in aqueous solutions. Detergents have been extensively exploited to mitigate this aggregation, and accomplish this by protecting the hydrophobic exterior of the membrane protein with their hydrophobic tails, while the polar heads of the detergents interact with the surrounding aqueous environment. Although detergents are of fundamental importance in many membrane protein studies, their selection is primarily done by trial and error screening. In this thesis, I will describe a method to utilize …

Chimera Ligand For Pili And Lectin A Protein Controls Antibiotic-Promoted Biofilm Formation, Swarming Motility, Tolerance And Persister Formation By Pseudomonas Aeruginosa, Hewen Zheng

Dissertations - ALL

Throughout the human history, the fight against bacterial infections had never stopped but the remedies for bacterial infections were often insufficient and for many infectious diseases, there was no treatment available. The revolution in antimicrobial infection therapy began with the discovery of penicillin by Alexander Fleming in 1928. However, since the first introduction of antibiotics, bacteria over time have evolved sophisticated resistant strains against almost all the available antibiotics which cause selection pressure on the bacteria to evolve their genetic makeup and develop resistance against such agents. Furthermore, bacteria can form surface attached multicellular communities known as biofilms. Bacteria residing …

Ecohydrology Of Natural And Restored Wetlands In A Glacial Plain, Kyotaek Hwang

Dissertations - ALL

More than half of wetland area in the U.S. have been converted to other land use types for agricultural use and development. Limited understanding of ecological services provided to society by wetlands is another reason for the massive wetland loss in the past. Section 404 of the Clean Water Act and the 1989 federal mandate of “no net wetland loss” supported increased efforts for wetland restoration and creation to compensate for two centuries of ecosystem degradation. Hydrology is a critical driver for wetland formation and sustainability, yet few studies have investigated the ecosystem benefits of restored or constructed wetlands relative …

Independence Through Patient Education In A Spinal Cord Injury Population, Justin Mctish

Electronic Theses and Dissertations

The Know More, Live Better program was developed because the population of people with Spinal Cord Injuries (SCI) includes a substantial number of young people, who often readmit into hospitals for preventable causes such as pressure ulcers, respiratory infections, and bowel/bladder infections. These complications can be avoided through patient education. A needs assessment was conducted at the SCI unit at Good Shepherd Rehabilitation Hospital in Allentown, PA. This assessment included structured observation of patient education in the therapy process, semi-structured interviews about site needs and patient education topics completed with patients and occupational therapists on staff, and surveys of multi-disciplinary …

Harnessing The Anopheles Microbiome To Conditionally Express Anti-Plasmodial Effectors During The Blood Meal, Jackie Shane

Electronic Theses and Dissertations

The control of vector-borne diseases such as malaria has been an extremely important research subject for hundreds of years. Because of the complex lifecycles of the pathogens that cause these diseases, finding a comprehensive treatment or preventative strategy has proven extremely difficult. Malaria alone is responsible for almost half a million deaths annually, most of them children under 5 years old. This disease is caused by parasitic protists in the genus Plasmodium that are transmitted to humans from Anopheles sp. mosquitoes. Most preventative strategies that are in use today revolve around controlling the vectors, including bed nets, insecticides, and larval …

Access To Care And The Use Of Healthcare Services By Women In Rural Cameroon: A Participatory Action Research Study, Grace Tadzong-Awasum

Electronic Theses and Dissertations

Women in rural Cameroon do not access health care as timeously and as often as they should. They fail to get screened for common diseases, with the consequence that such diseases are often diagnosed at a very advanced stage. This accounts for the high morbidity and mortality rates as well as low life expectancy recorded among women. The purpose of this study was to explore and understand the health access experiences of women in rural Cameroon. Methodology: Participatory action research was used guided by a Focused ethnography in phase one. Twenty-five women aged 21-77 years were recruited through local the …

Interaction Between Students’ Motivation And Physics Teachers’ Characteristics: Multiple Case Study, Fikret Korur, Ali Eryilmaz

The Qualitative Report

This study identified the process of interaction between students’ motivation and characteristics of two physics teachers: one who exhibited effective physics teacher characteristics frequently and one who exhibited the characteristics rarely. The two case teachers were selected to predict contrasting and comparable results. The data gathered from the semi-structured interviews, follow-up interviews, direct observation, video recordings, and field notes were analyzed both by single case and by cross-case analysis to strengthen the findings from two case teachers. Findings indicated that teachers’ characteristics like enthusiasm and giving examples from daily life increased students’ motivation by increasing their attention and willingness to …

Sepsis: The Applicability To Dental Care Professionals., C Coelho, M Mead

Peninsula Dental School

This discussion paper gives an overview of current understanding around sepsis with the aim of raising awareness. NICE requires all healthcare professionals, including dental care professionals to be trained in identifying people who may have sepsis. Enhancing knowledge about sepsis will help the dental team to educate their patients about sepsis, recognise the pathognomonic warning signs and the need for rapid treatment. This paper describes the multiple missed opportunities to diagnose sepsis in a baby and it is hoped the impact of reading this from the mother's perspective will reduce the risk of this happening again.

Protein Kinase A And High-Osmolarity Glycerol Response Pathways Cooperatively Control Cell Wall Carbohydrate Mobilization In Aspergillus Fumigatus, Leandro Jose De Assis, Adriana Manfiolli, Eliciane Mattos, João H.T.Marilhano Fabri, Iran Malavazi, Ilse D. Jacobsen, Matthias Brock, Robert A. Cramer, Arsa Thammahong, Daisuke Hagiwara, Laure Nicolas Annick Ries, Gustavo Henrique Goldman

School of Biomedical Sciences

Aspergillus fumigatus is an opportunistic human pathogen causing allergic reactions or systemic infections such as invasive pulmonary aspergillosis, especially in immunocompromised patients. The fungal cell wall is the main component responsible for recognition by the immune system, due to the specific composition of polysaccharide carbohydrates exposed on the surface of the fungal cell wall called pathogen-associated molecular patterns (PAMPs). Key enzymes in the fungal cell wall biosynthesis are a good target for fungal drug development. This report elucidates the cooperation between the HOG and PKA pathways in the mobilization of carbohydrates for fungal cell wall biosynthesis. We suggest that the …

Lozenge Tilings Of A Halved Hexagon With An Array Of Triangles Removed From The Boundary, Part Ii, Tri Lai

Department of Mathematics: Faculty Publications

Proctor's work on staircase plane partitions yields an exact enumeration of lozenge tilings of a halved hexagon on the triangular lattice. Rohatgi later ex- tended this tiling enumeration to a halved hexagon with a triangle cut o from the boundary. In his previous paper, the author proved a common generalization of Proctor's and Rohatgi's results by enumerating lozenge tilings of a halved hexagon in the case an array of an arbitrary number of triangles has been removed from a non-staircase side. In this paper we consider the other case when the array of tri- angles has been removed from the …

The Use Of Media Technologies In Long-Distance Relationships, Paola P. Soto Herrera

Theses

Communication technologies have helped reduce personal distances and stay connected. This study pursued the following questions: What are the most popular media used to communicate in long-distance relationships? Are those in long-distance relationships more likely to use rich or lean media? Do family, friends, and romantic partners differ in their selection of media? Instant Messaging, social media (Instagram, Facebook, Twitter, Snapchat), telephone (cellular, mobile, or landline), online video chat, online audio chat, SMS, and regular mail were the most used media. Respondents were significantly more likely to use rich media. Romantic partners were more likely than either family or friends …

Atom-Specific Activation In Co Oxidation, Simon Schreck, Elias Diesen, Jerry Larue, Hirohito Ogasawara, Kess Marks, Dennis Nordlund, Matthew Weston, Martin Beye, Filippo Cavalca, Fivos Perakis, Jonas Sellberg, André Eilert, Kyung Hwan Kim, Giacomo Coslovich, Ryan Coffee, Jacek Krzywinski, Alex Reid, Stefan Moeller, Alberto Lutman, Henrik Öström, Lars G. M. Pettersson, Anders Nilsson

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

We report on atom-specific activation of CO oxidation on Ru(0001) via resonant X-ray excitation. We show that resonant 1s core-level excitation of atomically adsorbed oxygen in the co-adsorbed phase of CO and oxygen directly drives CO oxidation. We separate this direct resonant channel from indirectly driven oxidation via X-ray induced substrate heating. Based on density functional theory calculations, we identify the valence-excited state created by the Auger decay as the driving electronic state for direct CO oxidation. We utilized the fresh-slice multi-pulse mode at the Linac Coherent Light Source that provided time-overlapped and 30 fs delayed pairs of soft …

The Cuban Health Paradigm: An Exploratory Analysis Through Lgbtq And Hiv/Aids Individual Perspectives, Sarah Dryfoos

Hatfield Graduate Journal of Public Affairs

The purpose of this research project was to develop an understanding of the social, systemic, interpersonal, structural, and political dynamics of the health care system in Cuba. This was done by selecting two populations of focus; LGBTQ and HIV/AIDS positive individuals. The health care system and social determinants of health are analyzed using these two populations as lenses. While there is a plethora of information about the formal Cuban health care system, there is a dearth of literature pertaining to the social determinants, especially as it relates to LGBTQ Cubans and their quality of life and health care experience. To …

Using What Students Have At Their Fingertips: Utilising Mobile Phones For Circular Writing, Mustafa Naci Kayaoğlu, Şakire Erbay Çetinkaya

The Qualitative Report

The integration of mobile phones into language teaching is at its infancy due to lack of uniform empirical support and limited studies focusing solely on vocabulary and pronunciation teaching. Arguing that writing should be merited further attention, we targeted a group of 26 English majoring students at a large-size public university in the northeast of Turkey to investigate their attitudes towards mobile phone-integrated language practice in the form of collaborative circular writing outside the school borders and collaborative whole class conferencing in the classroom with a seven-week case study. We gathered the qualitative data via an open-ended questionnaire, and a …

Sustainable Development: The Role Of School Libraries, Abiola Bukola Elaturoti

Library Philosophy and Practice (e-journal)

Over the past few years, sustainable development has emerged the latest development slogan. Sustainable development has been defined as the development that meets the social, economic and technological needs of the present without compromising the ability of future generations to meet their own needs. A good well-equipped library is a prerequisite for the intellectual, moral, and spiritual advancement and elevation of an individual right from childhood; it is an indispensable element of the absolute well-being of the citizens and that of the nation at large. To attain sustainable development, the role of libraries, and particularly school libraries, cannot be ignored …

Oculomotor Nerve Palsy After Influenza Vaccine In Inflammatory Bowel Disease., Rajesh Essrani Md, Rajesh K Essrani, Shehriyar Mehershahi, Arjun K Lohana, Anuraj Sudhakaran

Department of Medicine

Influenza and pneumococcal vaccines are recommended in inflammatory bowel disease patients. Several neurologic complications have been reported after influenza vaccines, such as Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy, and acute disseminated encephalomyelitis; however, rarely, oculomotor palsy will occur. We report the case of a 23-year-old male with a past medical history of ulcerative colitis on sulfasalazine who presented to the hospital with a complaint of blurry vision five days after an influenza vaccine. Most of the possible causes of oculomotor nerve palsy, such as stroke, intracranial space-occupying lesions, aneurysms, and infections, were ruled out by history, physical exam, blood work, …

Studying Galaxy Troughs And Ridges Using Weak Gravitational Lensing With The Kilo-Degree Survey, Margot M. Brouwer, Vasiliy Demchenko, Joachim Harnois-Déraps, Maciej Bilicki, Catherine Heymans, Henk Hoekstra, Konrad Kuijken, Mehmet Alpaslan, Sarah Brough, Yan Chuan Cai, Marcus V. Costa-Duarte, Andrej Dvornik, Thomas Erben, Hendrik Hildebrandt, Benne W. Holwerda, Peter Schneider, Cristóbal Sifón, Edo Van Uitert

Faculty and Staff Scholarship

We study projected underdensities in the cosmic galaxy density field known as 'troughs', and their overdense counterparts, which we call 'ridges'. We identify these regions using a bright sample of foreground galaxies from the photometric Kilo-Degree Survey (KiDS), specifically selected to mimic the spectroscopic Galaxy And Mass Assembly survey. Using background galaxies from KiDS, we measure the weak gravitational lensing profiles of the troughs/ridges. We quantify the amplitude of their lensing strength A as a function of galaxy density percentile rank P and galaxy overdensity δ, and find that the skewness in the galaxy density distribution is reflected in the …

What Does Walk Score® Really Measure?, Jorge Simbaqueba

Master's Theses

The Walk Score® (WS) algorithm works by identifying the closest amenities (grocery stores, banks, restaurants, and schools) and awarding points based on the distance to them from a given location. Scores have a range between 0 and 100. In 2011, the Walk Score® (WS) founders and advisory board modified the algorithm to better account for pedestrian friendliness by adding block length and intersection density data into the model to represent roadway characteristics and named it Street Smart Walk Score®.

Modelers attempting to quantify accessibility often focus on two components: a transportation element (or resistance factor) and an activity element (or …
