The International Humanity Foundation Co-Director Training Program, Indonesia: Supporting International Volunteers, Christina Darling

Capstone Collection

The following capstone paper takes a critical look at international volunteer programs and the potential negative consequences these programs may inadvertently have on the host community. The current volunteer Co-Director program at the International Humanity Foundations (IHF) is an archetype of this phenomenon. This paper examines the ways in which IHF falls short in achieving its mission and warns of the possible neo-colonial impact its Western volunteers may be having on the local communities around IHF’s centers.

The International Humanity Foundation Co-Director Training Program, Indonesia has been created in an effort strengthen IHF’s existing program by minimizing any negative impacts …

Rebuilding Houses, Rebuilding Ukraine: Peacebuilding Through Youth Service-Learning, Katherine Tremont

Capstone Collection

In order to successfully transform conflict in a complex situation such as Ukraine, it is critical to examine projects designed by Ukrainians themselves that support and reflect Ukrainian attitudes towards conflict and peace. Lviv Education Foundation is one such Ukrainian-run organization developing and implementing peacebuilding projects between the east and west of Ukraine. From interviews with Lviv Education Foundation personnel, this paper examines the feasibility of two important peacebuilding interventions through the lenses of positive and negative peace, basic human needs, and conflict transformation through ritual. This project finds that Lviv Education Foundation’s programs encourage peacebuilding in all three of …

The Legitimacy Of Fees For The Reservation Of Frequencies For A Multiplex Operator In The Period Before A Licence To Broadcast Is Actually Granted, Artur Salbert, Anna Żochowska-Sychowicz

internetowy Kwartalnik Antymonopolowy i Regulacyjny (internet Quarterly on Antitrust and Regulation)

The commencement of the dissemination of TV programmes in a multiplex is conditional upon: fi rst, obtaining a reservation of frequencies by a multiplex operator and second, obtaining licenses to broadcast by the broadcasters. The purpose of this article is to analyze the possibility of supporting an interpretation whereby the fees for the reservation of frequencies should only be paid by the multiplex operator starting from the time when the frequencies could actually be used by that multiplex operator to distribute programmes. The Article aims also to assess, in the event of disproving the above interpretation, the conformity of the …

History of Cultural Contact

Who wrote this text?

“In the country of ‘the lord of elephants’ the people are quick and enthusiastic, and entirely given to learning. They cultivate especially magical arts. They wear a robe thrown across them, with their right shoulder bare; their hair is done up in a ball on the top, and left undressed on the four sides. Their various tribes occupy different towns; their houses are built stage over stage.”

Co-Treatment With Conjugated Linoleic Acid And Nitrite Modulates Mitochondrial Respiration And Electron Transport Chain Activity In Vivo And Attenuates Mitochondrial Dysfunction During Cardiac Injury., Patrick Van Hoose

Electronic Theses and Dissertations

Cardiovascular disease and subsequent complications, such as myocardial infarction (MI), is the leading cause of death within the United States. Clinical intervention to reduce cardiac damage following myocardial ischemia is limited. Polyunsaturated fatty acids have been linked to an overall beneficial effect on cardiovascular health and function. Conjugated linoleic acid (cLA) is an 18:2 unsaturated fatty acid found within the diet in ruminant meat and dairy products. The cis-9 trans-11 isomer of cLA is the most prominent isomer within the diet and cLA has been linked to favorable outcomes in numerous disease states. The mechanism mediating the effects of cLA …

Chemoattractant Receptors Blt1 And Cxcr3 Regulate Anti-Tumor Immunity By Facilitating Cd8+ T Cell Migration To Tumors., Zinal S. Chheda

Electronic Theses and Dissertations

Presence of increased numbers of CD8⁺ T cells in the tumors correspond to better overall survival in the patients. Variety of immuno-therapies have shown considerable efficacy in the clinic, however, a multitude of patients remain unresponsive. Most of these immunotherapies rely on effector T cell responses in the tumor. A major obstacle in the success of these immunotherapies is poor recruitment of CD8⁺ T cells into tumors despite intact effector responses in the periphery. Therefore understanding the mechanisms that regulate CTL infiltration into tumors becomes essential. Previous studies in our laboratory suggested an important role for BLT1 in …

Standing In The Intersection : Using Photovoice To Understand The Lived Experience Of Black Gay College Students Attending Predominantly White Postsecondary Institutions., Erica Caton

Electronic Theses and Dissertations

The intersection of multiple oppressed identities is characterized by the compounded effects of victimization, intimidation and continued marginalization by dominant culture groups in society. Despite a growing body of knowledge about the individual experiences of racial and sexual minorities, there remains a lack of understanding of the unique life experiences of individuals with intersecting oppressed identities, specifically Black gay youth. Failure or inability to recognize, understand and take action in response to the needs of Black gay youth in college, perpetuates a culture of oppression that compromises the physical and mental well-being, and the academic success of these students.

Spreading Speeds And Traveling Waves In Some Population Models., Quancheng Meng

Electronic Theses and Dissertations

Virtually every ecosystem has been invaded by exotic organisms with potentially drastic consequences for the native fauna or flora. Studying the forms and rates of invading species has been an important topic in spatial ecology. We investigate two two-species competition models with Allee effects in the forms of reaction-diffusion equations and integro-difference equations. We discuss the spatial transitions from a mono-culture equilibrium to a coexistence equilibrium or a different mono-culture equilibrium in these models. We provide formulas for the spreading speeds based on the linear determinacy and show the results on the existence of traveling waves. We also study a …

The Time Frames Of New Venture Teams., Jason D’Mello

Electronic Theses and Dissertations

The central research question in this dissertation is: how do an individual’s perceptions of time impact a new venture team? Specifically, the study examined whether or not temporal depth relates to how reactive entrepreneurs may be to the environmental changes and threats that they face in their new venture team. I interviewed two cofounders from 40 new venture teams. The results suggest that cofounders in the same new venture team have very different perceptions of time. Their agreement, or congruence of temporal depth (future, past, and total) impacts their new venture team’s perception regarding environmental hostility. This relationship is negatively …

Synthesis And Functional Evaluation Of Peptide Modified Poly (Lactic-Co-Glycolic Acid) Nanoparticles To Inhibit Porphyromonas Gingivalis Biofilm Formation., Paridhi Kalia

Electronic Theses and Dissertations

Periodontal disease is an oral inflammatory disorder that afflicts roughly 46% of the adults in the U.S. Currently, treatment of periodontal disease involves the removal of plaque from the gingival pocket (with possible antibiotic treatment) and if necessary, gingival surgery. To our knowledge, no therapeutic approach exists that promotes host-biofilm homeostasis by limiting pathogen recolonization of the oral cavity after prophylaxis or treatment. The interaction of the pathogen Porphyromonas gingivalis with commensal streptococci is critical for initiation of periodontitis and represents a target for limiting P. gingivalis colonization of the oral cavity. Previous studies showed that a synthetic peptide …

Meta-Analyses Of Cardiovascular Responses To Rumination : Exploring Mechanisms Linking Depression And Hostility To Cardiovascular Disease., Lorna Y. Busch

Electronic Theses and Dissertations

Rumination intensifies and prolongs cardiovascular responses to stress. This emotion regulation strategy is characteristic of depression and hostility and may be a mechanism linking these dispositions to cardiovascular disease (CVD). The current meta-analyses investigate the magnitude of cardiovascular responses to rumination and the effectiveness of distraction in curtailing these responses. A literature search identified studies with rumination conditions and corresponding cardiovascular measures. A random effects model was applied to calculate heart rate (HR), diastolic blood pressure (DBP), and systolic blood pressure (SBP) weighted effect sizes for reactivity and recovery to angry rumination, sadness rumination, and rumination on positive emotion; heart …

Plant Community Responses To Invasive Shrub And Vine Removal In An Urban Park Woodland., Eric Richard Moore

Electronic Theses and Dissertations

Counter to what some people think, urban areas can be biodiversity hotspots. Maintaining this biodiversity can be challenging, since exotic shrubs and vines block sunlight and threaten native plant regeneration. Since 2007, the Louisville Olmsted Parks Conservancy (LOPC) has spent $2 million on invasive plant management in Cherokee Park. Before the project began, long-term transects were established by the LOPC to collect baseline presence/absence data on 11 invasive plant species. In 2014, I revisited these transects and documented presence/absence data on the entire plant community. I found that four species (garlic mustard, winter creeper, Japanese honeysuckle, and English ivy) have …

Cardiovascular Regulation And Effects Of Respiratory Motor Training In Patients With Chronic Spinal Cord Injury., Bonnie Legg Ditterline

Electronic Theses and Dissertations

This dissertation attempts to discover the mechanisms between cardiovascular and respiratory motor control post spinal cord injury (SCI): in normal, non-injured (NI) persons, cardiovascular regulation is dependent upon respiration, but there is nothing that suggests the mechanism for this relationship post-SCI. Thus we hoped to evaluate various aspects of cardiovascular regulation to further illustrate how this relationship is changed or unchanged by SCI. Chapter I describes the anatomy and physiology of the spine, respiratory system, and cardiovascular system in a NI person, and then describes how the function of these systems is changed by SCI. In addition, we describe therapies …

Differences In The Impact Of A Healthy Relationship Intervention On Family Cohesion, Parent-Child Relationship And Child Well-Being By Intimate Partner Violence Relationship Type., Erin E. Ness Roberts

Electronic Theses and Dissertations

Intimate Partner Violence (IPV) between the parents of children living at home has shown to have a profound effect on learning outcomes, developmental milestones, pediatric development, future mental health and overall physical safety and wellbeing (Anda, Block & Felitti, 2003). Although much research has been done on outcomes of child-witnesses and parenting in IPV relationships, some evidence suggests (Kernsmith, 2006) that the role of family dynamics among parents, as part of the IPV dynamic, is a critical variable. Other researchers (Johnson, 1995; Graham-Kevan & Archer, 2003) have theorized that violence with a high degree of controlling behaviors, often called Coercive …

This large group will have affected many aspects of our society, including families and healthcare providers. Decisions about medical care, caregiving, financial concerns, and new circumstances in living arrangements will be made. Perhaps no aspect of life will be as important as how one spends the end-of-life. Importantly, the care that individuals receive is likely an important aspect of this end-of-life experience. Interdisciplinary palliative care teams provide effective and comprehensive end-of-life care for patients …

Multiple Instance Fuzzy Inference., Amine Ben Khalifa

Electronic Theses and Dissertations

A novel fuzzy learning framework that employs fuzzy inference to solve the problem of multiple instance learning (MIL) is presented. The framework introduces a new class of fuzzy inference systems called Multiple Instance Fuzzy Inference Systems (MI-FIS). Fuzzy inference is a powerful modeling framework that can handle computing with knowledge uncertainty and measurement imprecision effectively. Fuzzy Inference performs a non-linear mapping from an input space to an output space by deriving conclusions from a set of fuzzy if-then rules and known facts. Rules can be identified from expert knowledge, or learned from data. In multiple instance problems, the training data …

The Unique Electrochemical Reactivity Of Small Metal Nanoparticles., Rafael A. Masitas

Electronic Theses and Dissertations

This dissertation describes the factors controlling metal nanoparticle (NP) oxidation, using Au oxidation in Br- and Ag oxidation in acid as model systems. We found that the oxidation potential depends on size, surface charge, and electrode material. Size has a dramatic effect, shifting about 200 mV from > 200 nm diameter down to 4 nm diameter. The shift is more dramatic below 4 nm. 2.3 nm average diameter Au NPs oxidized in the 300-500 mV range and 1.5 nm average diameter Au NPs displayed several sharp peaks from 200 mV to as low as -200 mV. These smallest Au NPs show …

In this thesis, artificial neural networks with curvelet keypoints are used to estimate the parameters of registration. Simulations show that the curvelet keypoints …

Construction Of An Initiated Chemical Vapor Deposition (Icvd) Reactor And Deposition Of Polytetrafluoroethylene (Ptfe) Thin Films Using Perfluoro-1-Octanesulfonyl Fluoride As The Initiator, Edgar Kiprop Kosgey

Graduate Theses/Dissertations

Initiated Chemical Vapor Deposition (iCVD) is a surface polymerization technique that is different from other traditional chemical vapor deposition (CVD) techniques. iCVD is carried under a vacuum without the use of solvents, therefore eliminating contaminations. An initiator and a monomer are metered into a vacuum reactor chamber. Inside the reaction chamber is an array of resistively heated filaments and a cooled substrate stage. Monomer species adsorb on to the cooled substrate surface underneath the filament array. The thermal energy from the resistively heated filaments breaks the bonds in the initiator molecule, generating free radicals. These generated free radicals chemisorb to …
