Is Addicted Phenomenology Just Human Phenomenology?, Benji Mahaffey, Tom Seppalainen

McNair Symposium

The phenomenon of addiction precedes, by millennia, our scientific inquiries into its psychological manifestations and neural bases. We did not need psychiatrists to ‘discover’ it; we have long been aware of its dark shadow lurking in our psyches. The discernable, often troubling behaviors of addicts notwithstanding, addiction is not the kind of phenomenon one observes; addiction is experienced, from the first-person perspective. Its defining features are qualitative: a subjective loss of control, an obsession, a compulsion. The overwhelming phenomenological salience of these features—especially of “compulsion”—has led addicts, philosophers, and psychiatrists alike to imagine that addiction is a discrete (phenomenological, natural, …

Small Satellite Conference

The EO-ALERT European Commission H2020 project proposes the definition, development, and verification and validation through ground hardware testing, of a next-generation Earth Observation (EO) data processing chain. The proposed data processing chain is based on a novel flight segment architecture that moves EO data processing elements traditionally executed in the ground segment to on-board the satellite, with the aim of delivering EO products to the end user with very low latency. EO-ALERT achieves, globally, latencies below five minutes for EO products delivery, and below one minute in realistic scenarios.

The proposed EO-ALERT architecture is enabled by on-board processing, recent improvements …

Comparing Heavy Metal Content Found In Spinach (Spinacia Oleracea) Grown On The Roof And Ground Sites At Portland State University, Tyler Robin, Gwynn R. Johnson, Olyssa Starry

McNair Symposium

As a result of urbanization, fresh, healthy food can be expensive and easily contaminated but space for local farming is limited. Roofs can be underutilized in densely populated cities and can offer a space for local fresh farming. The purpose of this study is to find if growing leafy vegetables on the roof can limit heavy metal exposure from air pollutants. By growing Spinach on five roofs and five ground locations around the Portland State University campus, at varying heights, we can extract the heavy metals found in these greens and compare them to each other. The expected results show …

The Effect Of Apremilast On Circadian Rhythm In The Ventral Tegmental Area, Courtney Ledford, Angela Ozburn

McNair Symposium

Chronic binge drinking negatively impacts society and is a leading cause of preventable deaths. The purpose of the experiment is to determine if regulation of circadian rhythms in the ventral tegmental area (VTA) will contribute to less ethanol consumption. The VTA plays a major role in addiction. A simple genetic animal model examines iHDID-1 mice and their binge-like drinking intake. The mice undergo Drinking in the Dark (DID) for 6 weeks prior to administration of apremilast or saline treatment at weeks 7 and 8. The mice are exposed to DID and sacrificed at two separate time points (ZT 3 and …

Liberalism, Settlement, Sacrifice: Towards A Genealogy Of Sacrificial Politics, Marshall Scheider, Adam Culver

McNair Symposium

In recent years, political theorists have begun to explore the sacrificial dimensions of liberalism and neoliberalism in the global North. Little of this work, however, grapples with the ways settler colonialism informs contemporary political sacrifice or conceptions of the sacrificial. This paper traces a genealogy of contemporary political sacrifice through the archive of early British colonialism in North America. When theorists ignore this archive, they do more than render colonization mute: they also fail to apprehend what I term political sacrifice’s differential function—the mechanism by which sacrifice’s burdens fall on subordinated groups while its benefits accrue to the socially, politically, …

Efficacy Of Curcumin In Asthma: A Systematic Review And Meta Analysis, Tabitha Grow, Adam Sadowski

McNair Symposium

Over 23 million people are affected by asthma in the United States and 262 million individuals globally. Asthma, if poorly controlled, is associated with significant morbidity as well as increased risk for mortality. Asthma involves several complex inflammatory pathways and processes including an increase in immune cell activation. Curcumin, the active constituent found in turmeric, has been studied in numerous in-vivo and in-vitro studies to generate anti-inflammatory effects in pulmonary diseases and, more recently, an increase in clinical data has become available. Since the most recent review assessing the role of curcumin in pulmonary disorders, additional clinical trials have been …

Correlation Effects On Intramolecular C-H...Oh And O-H...O Hydrogen Bond Interactions In Azelaic Acid: An Ab Initio Study, Sabina Kalata, Alina Huang, Ruben Parra

DePaul Discoveries

Electron correlation effects on both conventional, O-H…O, and nonconventional, C-H…O, intramolecular hydrogen bonds present in a selected azelaic acid folded conformation were evaluated ab initio using HF and MP2 methodologies. The relative strength of the hydrogen bonds was examined through different indicators derived from geometry, vibrational frequencies, and electron density along the hydrogen bond path. The HF method results in weaker O-H…O and C-H…O hydrogen bonds when compared with the corresponding results using the MP2 method. Additionally, the stability of the folded azelaic conformation is found to depend on the level of theory used. Accordingly, the zero-point corrected energies of …

Interspersed Denuded Zone (Idz): How Patchy Leaf Litter Dynamics In A Buckthorn-Invaded Urban Woodland Can Affect Microarthropod Species Richness, Angela Stenberg

DePaul Discoveries

Biodiversity loss may serve as a key diagnostic of the Anthropocene. An important driver of this loss is by means of invasive species. In this study of a forest preserve in Chicago, Illinois we examined Interspersed Denuded Zones (IDZs for short), which are areas of patchy leaf litter in invaded forests caused in this case by the rapid decomposition of litter from buckthorn (Rhamnus cathartica). We characterized the leaf litter mass in IDZs and enumerated litter-inhabiting microarthropod populations. We found that plots of high buckthorn density are associated with IDZs: there was significantly less leaf litter mass in …

Population Structure Analysis Of The Endangered Oak Quercus Brandegeei, Carolyn Brinckwirth

DePaul Discoveries

As humans continue to impact landscapes and ecosystems throughout the entire world, many plant and animal species have faced major changes in their environments. The rare endemic oak, Quercus brandegeei, is one such endangered species located in the Sierra La Laguna mountains of Baja California Sur, Mexico. This tree occurs solely on the ephemeral riverbeds of the mountains, which are inundated seasonally by hurricane waters. It is important to understand the fundamental characteristics, like spatial distribution, of Q. brandegeei in order to develop restorative management practices to protect this tree against extinction. Determining the geographic distribution of a species …

A Life Cycle Assessment Of Hospital Food Waste: A Model For Large Scale Commercial Impact Reduction, Demeri E. Amodeo, Christie Klimas

DePaul Discoveries

Current commercial landfill diversion techniques typically focus on recycling, but this method can be environmentally costly when compared scenarios involving the implementation of composting or waste reduction within large facilites. A life cycle assessment (LCA) can be used to provide better information on the environmental impact of different landfill diversion strategies. In this LCA, the impacts of individiual products were quantified in terms of global warming potential, which provides comparable impact categories for analysis. This study gathered information from previous literature about plant-based and omnivorous diets to simulate what the possible impact would be for a city, like Chicago, to …

Re-Conceptualizing Food Consumption And Its Educational Values, Chi Hong Nguyen, Toan Quoc Tran, Hay Ngoc Huynh, Linh Thuy Pham, Chi Thien Huu Le

Essays in Education

Food consumption has been largely researched in many areas. Most extant studies have highlighted the influences of socio-economic and cultural factors on people’s eating habits. These studies inform policy strategies by proposing campaigns and methods to improve nutritional intake among people of diverse socio-economic and geographical backgrounds. At the same time, they implicitly point out that food consumption may carry educational values that are co-constructed through food eaters’ engagement with the world. This requires researchers to go beyond the current methodological approaches that epistemologically focus on the factors that influence nutritional intake and eating habits. While little is known about …

Decoding The Roles Of Astrocytes And Hedgehog Signaling In Medulloblastoma, Terence Teixeira Duarte, Silvia Aparecida Teixeira, Luis Gonzalez-Reyes, Rui Manuel Reis

Publications and Research

The molecular evolution of medulloblastoma is more complex than previously imagined, as emerging evidence suggests that multiple interactions between the tumor cells and components of the tumor microenvironment (TME) are important for tumor promotion and progression. The identification of several molecular networks within the TME, which interact with tumoral cells, has provided new clues to understand the tumorigenic roles of many TME components as well as potential therapeutic targets. In this review, we discuss the most recent studies regarding the roles of astrocytes in supporting sonic hedgehog (SHH) subgroup medulloblastoma (MB) and provide an overview of MB progression through SHH …

On The Relationship Of Diabetes And Sleep Apnea: Evolution And Epigenetics, Nancy Wilson

Undergraduate Honors Theses

This thesis gives an overview of the relationship between diabetes, sleep apnea, obesity, and heart disease. It then addresses evidence that the traditional understanding of this relationship is incomplete or misleading. In the process, there is a brief discussion of the evolutionary rationale for the development and retention of sleep apnea in light of blood sugar dysregulation, as an adaptive mechanism in response to environmental stressors, followed by a brief overview of the general concepts of epigenetics. Finally, this paper presents the results of a literature search on the epigenetic marks and changes in gene expression found in sleep apnea …

A New Function For Amyloid-Like Interactions: Cross-Beta Aggregates Of Adhesins Form Cell-To-Cell Bonds, Peter N. Lipke, Marion Mathelié-Guinlet, Albertus Viljoen, Yves F. Dufrêne

Publications and Research

Amyloid structures assemble through a repeating type of bonding called “cross-β”, in which identical sequences in many protein molecules form β-sheets that interdigitate through side chain interactions. We review the structural characteristics of such bonds. Single cell force microscopy (SCFM) shows that yeast expressing Als5 adhesin from Candida albicans demonstrate the empirical characteristics of cross-β interactions. These properties include affinity for amyloid-binding dyes, birefringence, critical concentration dependence, repeating structure, and inhibition by anti-amyloid agents. We present a model for how cross-β bonds form in trans between two adhering cells. These characteristics also apply to other fungal adhesins, so the mechanism …

Chief Executive Officers’ Perceptions Of Collective Organizational Engagement And Patient Experience In Acute Care Hospitals, Mary Lynn Lunn, Andrea D. Ellinger, Kim F. Nimon, Jonathon Rb Halbesleben

Human Resource Development Faculty Publications and Presentations

The concept of employee engagement has garnered considerable attention in acute care hospitals because of the many positive benefits that research has found when clinicians are individually engaged. However, limited, if any, research has examined the effects of engaging all hospital employees (including housekeeping, cafeteria, and admissions staff) in a collective manner and how this may impact patient experience, an important measure of hospital performance. Therefore, this quantitative online survey-based study examines the association between 60 chief executive officers' (CEOs') perceptions of the collective organizational engagement (COE) of all hospital employees and patient experience. A summary measure of the US …

The Vertical Greenery Systems Significant Role In Achieving Better Architectural And Urban Thermal Performance., Ahmed Morsi, Nesma Elian

Mansoura Engineering Journal

Vertical Greenery Systems (VGS) are self-sustaining garden systems that can be designed on the building envelope, they represent an innovative approach to rebalance the urban heat island phenomena that have become a major problem in recent times, resulting from urbanization and activities polluting the environment, especially in cities and urban with high density. These systems are becoming common and require further knowledge about their particular impacts on the building and the environment. In recent decades, various studies have been conducted to demonstrate that these systems can contribute to improving the urban environment and enhancing buildings' efficiency, though thermal research remains …

Influence Of Posterior Elements On The Correlations Between Microarchitecture Parameters Of Trabecular Bone And Stochastic Predictors From The Dxa Scans Of Human Lumbar Vertebrae, Indu Reddy Enukonda

Health and Kinesiology Theses

Osteoporosis is a bone disease affecting both postmenopausal women and older men. Bone fractures caused by osteoporosis are a major health concern, creating a great economic burden to our society. Bone mineral density (BMD), a measure of bone mass by Dual-energy X-ray Absorptiometry (DXA), is a major risk factor for bone fractures. In addition to BMD, trabecular microarchitecture also contributes to bone strength and therefore is a risk factor for osteoporotic fractures. Recently, stochastic predictors derived from DXA scans have been found to correlate with trabecular microarchitecture in human vertebrae. In routine clinical scans of the human lumbar spine, posterior …

Carveol Attenuates Seizure Severity And Neuroinflammation In Pentylenetetrazole-Kindled Epileptic Rats By Regulating The Nrf2 Signaling Pathway, Arooj Mohsin Alvi, Lina Tariq Al Kury, Abdullah Alattar, Ikram Ullah, Asmaa Jan Muhammad, Reem Alshaman, Fawad Ali Shah, Arif Ullah Khan, Jinxing Feng, Shupeng Li

All Works

Epilepsy is a neurodegenerative brain disorder characterized by recurrent seizure attacks. Numerous studies have suggested a strong correlation between oxidative stress and neuroinflammation in several neurodegenerative disorders including epilepsy. This study is aimed at investigating the neuroprotective effects of the natural compound carveol against pentylenetetrazole- (PTZ-) induced kindling and seizure model. Two different doses of carveol (10 mg/kg and 20 mg/kg) were administered to male rats to determine the effects and the effective dose of carveol and to further demonstrate the mechanism of action of nuclear factor E2-related factor (Nrf2) in PTZ-induced kindling model. Our results demonstrated reduced levels of …
