Social Networks Differ Depending On Aggressive And Affiliative Interactions Of Captive Ring-Tailed Lemurs (Lemur Catta), Kerry Marcus

The Plymouth Student Scientist

Social network analysis provides a deeper understanding of the dynamic social relationships within a social group through identifying centrality, subgroups, isolated individuals and preferred or avoided dyads which have shown effective for the study of dominance hierarchies (Funkhouser et al., 2018). However, this is rarely used in captive environments despite showing promise for its management. In this study, social network analysis was used to investigate the dominance hierarchy, dyadic and group-level social relationships in a captive group of 11 ring-tailed lemurs (Lemur catta) at Bristol Zoo Gardens. Focal-animal and instantaneous scan sampling were used to collect 90 total hours of …

Population Density And Immune Investment In Different Developmental Stages Of Tenebrio Molitor, Nathan Dennis

The Plymouth Student Scientist

Immune responses are costly, so organisms should invest in immunity when environmental cues indicate a high risk of infection. The density-dependent prophylaxis (DDP) hypothesis proposes that because the risk of infection increases with population density, organisms should invest more in immunity under crowded conditions. The aims of this study were to investigate DDP in the mealworm beetle Tenebrio molitor and to assess whether density-dependent immune investment differs between developmental stages. T. molitor larvae weighing 50-130mg were assigned to either a low-, moderate-, or high-density treatment for 31 days. After which the phenoloxidase (PO) activity, encapsulation and capsule melanisation responses, and …

Diet Cola And Glycaemia: The Acute Effects Of A Preload Containing The Non-Nutritive Sweeteners Aspartame And Acesulfame-K On The Glycaemic Response To A Glucose Load, Luke Solomi

The Plymouth Student Scientist

Epidemiological evidence has linked non-nutritive sweeteners (NNS) with potential adverse health outcomes such as obesity, metabolic dysfunction, and poor blood glucose control. This study aims to ascertain the acute glycaemic effects of the NNS aspartame and acesulfame-K in diet cola when consumed prior to a glucose load. Ten participants were recruited to take part and instructed to attend the laboratory in a fasted state on two occasions. Participants drank a preload containing either 250 mL carbonated water (CW) or 250 mL caffeine-free diet cola (DC) 10 minutes prior to consumption of a 25 g glucose beverage in 125 mL water. …

Developing A Common Language Of Ethical Engagement In Teaching: Lessons For And From A Time Of Crisis, Richard D. Sawyer

Northwest Journal of Teacher Education

This article explores how educators may develop and contribute to a common language of ethical engagement, a language that rises above specific actions but is grounded in ethical practice and scholarship. Questions are raised about how online education may further the patterns educational inequities in the United States. An ethics framework is explored through a comparison. The author explores the educational principles--not standards—that educators can surface in their teaching practice. A discussion is included of recent dilemmas and problems with online teaching environments, underscoring the need for ethical principles helping to frame practice.

The Meaning Of Javanese Adolescents' Involvement In Youth Gangs During The Discoveries Of Youth Identity: A Phenomenological Study, Enung Hasanah, Supardi Supardi

The Qualitative Report

Yogyakarta is a part of Javanese society. Javanese culture, which always enforces moral values, has a practical implication toward adolescents' views about their self-identity. Yogyakarta adolescents are well known to have positive self-identity, good behavior, and tend to become successful persons in their youth. In the past years, a phenomenon of youth gangs that often conduct irresponsible acts such as brawls, stabbing terror, and even murder has emerged. The question of the research is how adolescent members of a youth gang give meaning to their involvement in a youth gang. To answer the question, we used a phenomenological research method. …

Acute Kidney Injury Pathology And Pathophysiology: A Retrospective Review, Joseph P. Gaut, Helen Liapis

Open Access Publications

Acute kidney injury (AKI) is the clinical term used for decline or loss of renal function. It is associated with chronic kidney disease (CKD) and high morbidity and mortality. However, not all causes of AKI lead to severe consequences and some are reversible. The underlying pathology can be a guide for treatment and assessment of prognosis. The Kidney Disease: Improving Global Outcomes guidelines recommend that the cause of AKI should be identified if possible. Renal biopsy can distinguish specific AKI entities and assist in patient management. This review aims to show the pathology of AKI, including glomerular and tubular diseases.

A Model To Explain Statewide Differences In Covid-19 Death Rates, James L. Doti

Economics Faculty Articles and Research

COVID-19 death rates per 100,000 vary widely across the nation. As of September 1, 2020, they range from a low of 4 in Hawaii to a high of 179 in New Jersey. Although academic research has been conducted at the county and metropolitan levels, no research has rigorously examined or identified the demographic and socioeconomic forces that explain state-level differences. This study presents an empirical model and the results of regression tests that help identify these forces and shed light on the role they play in explaining COVID-19 deaths.

A stepwise regression model we tested exhibits a high degree of …

A Mathematical Model For The Effect Of Social Distancing On The Spread Of Covid-19, Anna Singley, Hannah Callender Highlander

Spora: A Journal of Biomathematics

Social distancing is an effective method of impeding the spread of a novel disease such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but is dependent on public involvement and is susceptible to failure when sectors of the population fail to participate. A standard SIR model is largely incapable of modeling differences in a population due to the broad generalizations it makes such as uniform mixing and homogeneity of hosts, which results in lost detail and accuracy when modeling heterogeneous populations. By further compartmentalizing an SIR model, via the separation of people within susceptible and infected groups, we can more …

A Mechanistic Study On The Non-Genotoxic Carcinogenicity Of The Food Contaminant Semicarbazide, Daniel P. Fitzpatrick

SURE Journal: Science Undergraduate Research Experience Journal

Semicarbazide was brought to the forefront of scientific discussions by the scientific community in the early 2000’s as the substance was discovered in several food products from both synthetic and natural sources. Although semicarbazide was processed through several toxicological assays and classified as a non-genotoxic carcinogen, underwhelming amounts of toxicological data exists for the compound. The present study is one of the first in-vitro studies to examine the relationship between sub-pathophysiological concentrations of reactive oxygen species and the anomalous non-genotoxic carcinogenicity induced by semicarbazide through the upregulation of intracellular signalling pathways. A novel finding of the present study was where …

Weight Status Of Children Aged 2-5 Years Old, Attending A Paediatric Outpatient Clinic And Its Association With Parental Feeding Style And Parental Perceptions Of Weight Status, Aisling Lee, Helen Callaghan, Dara Gallagher Dr, Annette Lalor, Louise Rattigan, Hilary Greaney, Laura Keaver

SURE Journal: Science Undergraduate Research Experience Journal

Background: A child’s weight status can allow health care professionals to assess their developmental growth. A child having a low or high weight for height could be due to an imbalance in nutrient intake occurring. It is important to balance dietary intake and physical activity to maintain a healthy weight status. Excessive consumption of food can lead to an overweight/obese weight status which is linked to non-communicable diseases. Parental feeding style can directly impact a child’s set of eating behaviours. Therefore, parents have a strong influence over a child’s growth pattern. In addition, parental awareness of childhood obesity is reported …

Recovery And Repurposing Of Thermal Resources In The Mining And Mineral Processing Industry, Shannon H. Mclean, Jeffrey Chenier, Sari Muinonen, Corey A. Laamanen, John A. Scott

Journal of Sustainable Mining

The consumption of energy contributes significantly to the overall cost of operations and the environmental impact of the mining and mineral processing industry. However, despite a few notable exceptions, most of the resulting waste heat produced is dissipated, without recovery, into the environment. There is also a lot of stored heat in mine water which can be tapped into long after a mine has closed. There is, therefore, significant opportunity to improve the industry's sustainability through increasing the amount of waste heat recovered and repurposed.

Ammonia-Ca-K Competitive Ion-Exchange On Zeolites In Mining Wastewater Treatment: Batch Regeneration And Column Performance, Roberto Martín Narbaitz, Zachary G. Chartrand, Majid Sartaj, Jason Downey

Journal of Sustainable Mining

This manuscript addresses the treatment explosives-impacted mining wastewaters (EIMWW) using ion-exchange to remove elevated levels of ammonia. Repeated batch loading-regeneration cycles were conducted for two commercially available zeolite media used in the treatment of ammonia-ladenEIMWW to establish the effects of competing ions and regeneration solution composition. The Northern Ontario EIMWW tested contained 3.87 meq/L total ammonia (TA) as well as 2.85 meq/L Kþ and 3.9 meq/L Ca2þ.The media studied were a natural clinoptilolite and a modified clinoptilolite (SIR-600). Five regenerant solutions with different NaCl and KCl concentrations were evaluated. The presence of potassium in the regenerant was found to hinder …

Developing A Model Of Graduate Teaching Assistant Teacher Efficacy: How Do High And Low Teacher Efficacy Teaching Assistants Compare?, Cody R. Smith, Cesar Delgado

School of Natural Resources: Faculty Publications

Graduate teaching assistants (TAs) are often responsible for teaching introductory courses to undergraduate science, technology, engineering, and mathematics students. The TAs are usually novices at teaching, and an important factor in their resilience and persistence in the face of inevitable challenges is self-efficacy. Little is known about what affects TA teacher efficacy or whether and how high- and low-efficacy TAs differ in their development as teachers. Bridging these gaps in the literature will inform best practices in developing and implementing professional development (PD) for TAs. Using a mixed-methods sequential exploratory research design, this study found differences in high- and low-efficacy …

Genomic Adaptations To Salinity Resist Gene Flow In The Evolution Of Floridian Watersnakes, Rhett M. Rautsaw, Tristan D. Schramer, Rachel Acuña, Lindsay N. Arick, Mark Dimeo, Kathryn P. Mercier, Michael Schrum, Andrew J. Mason, Mark J. Margres, Jason L. Strickland, Christopher L. Parkinson

Publications and Research

The migration-selection balance often governs the evolution of lineages, and speciation with gene flow is now considered common across the tree of life. Ecological speciation is a process that can facilitate divergence despite gene flow due to strong selective pressures caused by ecological differences; however, the exact traits under selection are often unknown. The transition from freshwater to saltwater habitats provides strong selection targeting traits with osmoregulatory function. Several lineages of North American watersnakes (Nerodia spp.) are known to occur in saltwater habitat and represent a useful system for studying speciation by providing an opportunity to investigate gene flow …

Environmental Justice, Indigenous Knowledge Systems, And Native Hawaiians And Other Pacific Islanders, Michael S. Spencer, Taurmini Fentress, Ammara Touch, Jessica Hernandez

Human Biology Open Access Pre-Prints

Native Hawaiian and other Pacific Islanders, and the environment that they are in relationship with, have been the targets of exploitation, extraction, and destruction. Environmental atrocities throughout the Pacific have demonstrated the ways imperialism, capitalism and white supremacy drive destruction through efforts to dominate and exploit for material gain. The relationship between Pacific people and the environment, which defines who they are socially, spiritually, and ancestrally, continues to be damaged and even severed by these injustices. The purpose of this paper is to provide examples of major environmental injustices in the Pacific and to develop a deeper understanding of the …

Earth and Environmental Sciences Faculty Publications

Food security in a warming world is a grave concern for rapidly growing impoverished populations. Low-latitude inland fisheries provide protein for millions of rural poor, yet the impacts of high-frequency climate oscillations on these aquatic ecosystems are unknown. Here, we present a sub-annual-to-annual resolution paleolimnological reconstruction of upwelling, productivity, and algal composition at Lake Tanganyika, one of Africa's largest landlocked fisheries. The data reveal increases in diatom production at centennial-scale solar irradiance maxima, and interannual variability in upwelling linked to La Niña. Our study shows that interactions between global climatic controls and El Niño-Southern Oscillation teleconnections exert profound influences on …
