Analysis Of The Social Entrepreneurship Ecosystem In Guanajuato, Mexico From Complex Social Networks, Vicente Espínola-Verdín, Luis Adolfo Torres-González

Journal of Management for Global Sustainability

In Mexico, the interest in social enterprises has increased in the last 20 years as an alternative to the profit maximization approach of the company. They seek to solve a social problem, improve the conditions of the population they are targeting, modify the consumption habits of their clients, and seek social transformation through a social business model. The policies to promote entrepreneurship in the State of Guanajuato have focused mainly on the creation of traditional and, recently, technology-based enterprises with limited promotion of social entrepreneurship, which is sometimes confused with projects with low added value and without a clear strategy. …

“It Made Me Question If I Was In The Right Hands”: Exploring Cancer Prognostic Conversations Between Providers And Latinx Patients, Yesenia Anabel Carrillo

Master's Theses

People of color are often confronted by barriers within the health-care system that white people are not likely to encounter. Latinx patients are among those who experience racial health disparities, typically due to the lack of health literacy support and limited resource access. Drawing on previous work that focuses on exploring patient, provider, and caregiver preferences for cancer prognostic conversations; this study explores perceptions of cancer prognostic conversations between providers and Latinx patients to better understand the degree of cultural competence among providers and opportunities for enhancing interpersonal communication with Latinx patients. Interviews with seven patients and five providers were …

Association Between Meal Dietary Inflammatory Potential And Postprandial Sleepiness, Samantha Beth Kalb

Master's Theses

The amount and composition of food that is consumed are known to contribute toinflammation and may affect how we feel in the following hours. The aim of this research was to determine if the inflammatory potential of a single meal is associated with level of postprandial sleepiness. Participants (n = 70) recorded intake of one of their meals, then reported their degree of postprandial sleepiness (Stanford Sleepiness Scale), average activity level, average hours of nightly sleep, and daytime sleepiness (Epworth Sleepiness Scale). The Dietary Inflammatory Index (DII) of the meal was estimated by adjusting DII parameters by 26%, reflecting the …

A Chemical And Minerological Fingerprint Of Hydraulic Mining Sediment, In The Yolo Bypass, California, Stephanie Annette Meursing

Master's Theses

Hydraulic gold mining in California, began not long after the discovery of gold in 1848. This type of mining dislodged large amounts of sediment, which were then deposited downstream. The Yolo Bypass, downstream from several northern California rivers, has received and continues to receive hydraulic mining sediment (HMS). The main goal of this study was to document the chemical and mineralogical characteristics of HMS in the bypass. Twelve borehole cores from the bypass and five in-situ auriferous gravel samples, which were used for background concentrations, were collected for this study. All twelve cores had higher Hg concentrations than the in-situ …

Hybridity And Habitation: A Rhetorical Analysis Of Interior Design In Live-Action Cyberpunk Films Through The Lens Of Posthumanism And Thing Theory, Sydney Ng

Master's Theses

Characterized by hyper-urban environments, extreme class division, and an abundance ofcorporate oversight, the cyberpunk subgenre of science-fiction is a prime candidate for scholarly research on speculative interior design and associated technologies. Using the theoretical frameworks of posthumanism, or the concept that humans will transcend their current biological form in the near future, and thing theory, or the worldview that objects are able to enact their autonomy on living subjects, interior design in three live-action films in the cyberpunk subgenre were analyzed in order to determine how depictions of future spaces reflect present ideations of our potential real future. Metaphor analysis …

Urban Edge Effects On Soil Conditions, Stand Structure, And Understory Composition In A Coast Redwood Forest, Nanako Oba

Master's Theses

Forests in the wildland-urban interface (WUI) can experience edge effects caused byhuman activities, such as timber harvest and urban development, altering vegetation composition and structure. Both the WUI and resulting edge effects are well studied in general; however, the influences of the urban edge on coast redwood forests specifically are not well understood. I analyzed soil properties, stand structure, and understory composition in a coast redwood preserve in the Santa Cruz Mountains, California using twenty 300 m transects established across an anthropogenic edge and twenty transects within a forest interior control. Spearman’s rank correlations indicated that several variables exhibited positive …

Existence Results For Nonlinear Schrodinger Equations Involving The Fractional (P, Q)-Laplacian And Critical Nonlinearities, Huilin Lv, Shenzhou Zheng, Zhaosheng Feng

School of Mathematical & Statistical Sciences Faculty Publications

In this article, we consider the existence of ground state positive solutions for nonlinear Schrodinger equations of the fractional (p, q)-Laplacian with Rabinowitz potentials defined in R-n,

(-Delta)(p)(s1) u + (-Delta)(q)(s2) q u+ V(epsilon x)(vertical bar u vertical bar(p-2)u+vertical bar u vertical bar(q-2)u) =lambda f(u) + sigma vertical bar u vertical bar q*(-2)(s2)u.

We prove existence by confining different ranges of the parameter lambda under the subcritical or critical nonlinearities caused by sigma = 0 or 1, respectively. In particular, a delicate calculation for the critical growth is provided so as to avoid the failure of a global Palais-Smale condition …

Recurrent Stroke Prediction Using Machine Learning Algorithms With Clinical Public Datasets: An Empirical Performance Evaluation, Fadratul Hafinaz Hassan, Mohd Adib Omar

Baghdad Science Journal

Recurrent strokes can be devastating, often resulting in severe disability or death. However, nearly 90% of the causes of recurrent stroke are modifiable, which means recurrent strokes can be averted by controlling risk factors, which are mainly behavioral and metabolic in nature. Thus, it shows that from the previous works that recurrent stroke prediction model could help in minimizing the possibility of getting recurrent stroke. Previous works have shown promising results in predicting first-time stroke cases with machine learning approaches. However, there are limited works on recurrent stroke prediction using machine learning methods. Hence, this work is proposed to perform …

Emerging Themes In The Molecular Pathogenesis Of Enterotoxigenic Escherichia Coli, James M Fleckenstein, Alaullah Sheikh

2020-Current year OA Pubs

Enterotoxigenic Escherichia coli (ETEC) are ubiquitous diarrheal pathogens that thrive in areas lacking basic human needs of clean water and sanitation. These genetically plastic organisms cause tremendous morbidity among disadvantaged young children, in the form of both acute diarrheal illness and sequelae of malnutrition and growth impairment. The recent discovery of additional plasmid-encoded virulence factors and elucidation of their critical role in the molecular pathogenesis of ETEC may inform new approaches to the development of broadly protective vaccines. Although the pathogens have been closely linked epidemiologically with nondiarrheal sequelae, these conditions remain very poorly understood. Similarly, while canonical effects of …

Evaluating Varieties Of Alfalfa And Tall Fescue For Tolerance To Over-Grazing By Cattle, Robert F. Spitaleri, Jimmy C. Henning, Charles T. Dougherty, Garry D. Lacefield, B. T. Larson

IGC Proceedings (1977-2023)

Cultivars of alfalfa (Medicago sativa L.) and tall fescue (Festuca arundinacea Schreb.) were seeded in small (1.5 m x 4.6 m) plots and harvested for estimating yield the following spring. Plots were then grazed by cattle continuously for the remainder of the season so as to keep stand heights at 7.5 cm or less. This procedure was repeated for one or two more grazing seasons, depending on stand survival. Stands were visually rated for stand in the fall and spring. Marked differences in grazing tolerance were observed among alfalfa cultivars, following closely the commercial designations as grazing-type or …

The Role Of Cattle Dung In Seed Dispersal Of Major Species In A Zoysia Japonica Pasture In Japan, K. Shimoda, S. Sakanoue

IGC Proceedings (1977-2023)

To evaluate the role of cattle dung in seed dispersal of major species in Zoysia japonica pasture in Japan, we investigated the species composition and density of seeds in cattle dung by means of a germination test. Of 20 major species which had a mean coverage of more than 0.1%, 90% were detected as seeds in cattle dung. In addition, the species composition and density of seeds in cattle dung differed among three sampling seasons. Seeds of the six most prevalent species in terms of coverage were detected from cattle dung during the growing season. Hence, we conclude that it …

Stimulation Of Ammonia Oxidizer And Denitrifier Abundances By Nitrogen Loading: Poor Predictability For Increased Soil N2o Emission, Yong Zhang, Feng Zhang, Diego Abalos, Yiqi Luo, Dafeng Hui, Bruce A. Hungate, Pablo García-Palacios, Yakov Kuzyakov, Jørgen Eivind Olesen, Uffe Jørgensen, Ji Chen

Biology Faculty Research

Unprecedented nitrogen (N) inputs into terrestrial ecosystems have profoundly altered soil N cycling. Ammonia oxidizers and denitrifiers are the main producers of nitrous oxide (N₂O), but it remains unclear how ammonia oxidizer and denitrifier abundances will respond to N loading and whether their responses can predict N-induced changes in soil N₂O emission. By synthesizing 101 field studies worldwide, we showed that N loading significantly increased ammonia oxidizer abundance by 107% and denitrifier abundance by 45%. The increases in both ammonia oxidizer and denitrifier abundances were primarily explained by N loading form, and more specifically, organic N …

The Immobilization Of Ticagrelor On Implant Materials And Corrosion And Biofouling Inhibition By Novel Layered Polymer Thin Films For Marine Application, Tell Lovelace

Electronic Theses and Dissertations

Percutaneous coronary interventions are a widely used cardiovascular surgery which is typically accompanied by the insertion of a vascular stent. After the procedure patients are put on dual anti-platelet therapy (DAPT) to prevent stent thrombosis, a common complication to this procedure in which platelets aggregate in the blood vessel on the inserted stent. Systemic deactivation of platelets in patients via oral DAPT results in patients becoming bleeding risks in future medical procedures, necessitating the development of a localized delivery system for anti-platelet medications from the surface of the stent. A novel anti-thrombogenic vascular stent coating has been prepared by covalent …

The Environmental Kuznets Curve For Deforestation In Indonesia, Dara Adila, Nunung Nuryartono, Mandar Oak

Economics and Finance in Indonesia

This study provides empirical findings on the relationship between deforestation and income in 32 provinces in Indonesia. To enrich the discussion on deforestation, this study investigates the impact of the factors of population, roundwood production, land area, and main crop production on deforestation. The selected main crops in Indonesia are oil palm, coffee, coconut, rubber, and cacao. The results confirm the existence of the EKC relationship between deforestation and income in Indonesia. The study also finds that oil palm production positively affects tree cover loss, but the production of natural rubber has the opposite impact on deforestation.

In general, rice injury decreased as application timing was delayed with the least amount of rice injury occurring when the VLCFA inhibiting herbicides were …

A Cross-Ecoregion Evaluation Of Nitrogen Fixation And Denitrification In Streams And Rivers Of The United States Of America, Amy Marcarelli, Erin K. Eberhard, Michelle Kelly, Kevin Nevorski

Michigan Tech Publications, Part 1

It is typically assumed that dinitrogen (N2) fixation and denitrification are mutually exclusive processes in riverine ecosystems because N2 fixation is favored in high light, low nitrogen (N) environments but denitrification is favored under anoxic, high N conditions. Yet recent work in marine and lake ecosystems has demonstrated that N2 fixation can happen under high N conditions and in sediments, challenging this assumption. We conducted a cross-ecoregion study to test the hypothesis that N2 fixation and denitrification would co-occur in streams and rivers across a range of reactive N concentrations. Between 2017 and 2019, we sampled 30 streams in 13 …
