Exposure And Potential Effects Of Pesticides And Pharmaceuticals In Protected Streams Of The Us National Park Service Southeast Region, Paul M. Bradley, Kristin M. Romanok, Jeffrey R. Duncan, William A. Battaglin, Jimmy M. Clark, Michelle L. Hladik, Bradley J. Huffman, Luke R. Iwanowicz, Celeste A. Journey, Kelly L. Smalling

United States National Park Service: Publications

Globally, protected areas offer refugia for a broad range of taxa including threatened and endangered species. In the United States (US), the National Park Service (NPS) manages public lands to preserve biodiversity, but increasing park visitation and development of surrounding landscapes increase exposure to and effects from bioactive contaminants. The risk (exposure and hazard) to NPS protected-stream ecosystems within the highly urbanized southeast region (SER) from bioactive contaminants was assessed in five systems based on 334 pesticide and pharmaceutical analytes in water and 119 pesticides in sediment. Contaminant mixtures were common across all sampled systems, with approximately 24% of the …

No Change Detected In Culturable Fungal Assemblages On Cave Walls In Eastern Canada With The Introduction Of Pseudogymnoascus Destructans, Karen J. Vanderwolf, David Malloch, Donald F. Mcalpine

KIP Articles

Studies of fungi in caves have become increasingly important with the advent of white-nose syndrome (WNS), a disease caused by the invasive fungus Pseudogymnoascus destructans (Pd) that has killed an estimated 6.5 million North American bats. We swabbed cave walls in New Brunswick, Canada, in 2012 and 2015 to determine whether the culturable fungal assemblage on cave walls changed after the introduction of Pd and subsequent decrease in hibernating bat populations. We also compared fungal assemblages on cave walls to previous studies on the fungal assemblages of arthropods and hibernating bats in the same sites. The fungal diversity of bats …

Photographic Records Confirming The Presence Of Wild Turkey (Meleagris Gallopavo Ssp.) In The Sierra Gorda Biosphere Reserve Of Guanajuato, Mexico, Manuel Rangel-Rojas, Juan F. Charre-Medellín, Tiberio C. Monterrubio-Rico, Gloria Magaña-Cota, José S. Contreras-Robledo, Luis Sáenz-Villa, Luis Vázquez-Sandoval

Western North American Naturalist

The Wild Turkey (Meleagris gallopavo sspp.) is a galliform historically distributed throughout the Sierra Madre Occidental, Sierra Madre Oriental, and central Mexico. However, it is currently extirpated from much of its original range. Herein, we report the presence of Wild Turkey in temperate forests of the Sierra Gorda Biosphere Reserve of Guanajuato (SGBRG). We also highlight the importance of our observations in the context of possible natural dispersal and potential range recovery of suitable areas within the historical range in the interior of Guanajuato State. As a result of a wildlife survey program in the SGBRG, a set of …

Building Skills For And Implementing Course Based Undergraduate Research Experiences (Cures) Across An Environmental Studies Curriculum, Alanna L. Lecher, Cassandra S. Korte

Faculty and Staff Publications & Presentations

Course Based Undergraduate Research Experiences (CUREs) are an effective method of teaching students not only content, but also critical thinking, scientific practice, and other skills beneficial to their education and success. They lower the barrier to participation in undergraduate research, thereby increasing access to entry. Thus, CUREs are especially valuable to under-performing students as they are an effective means of bridging the achievement gap. Due to the value and effectiveness of CUREs in student development, Lynn University has implemented a means by which students are exposed to CUREs and skills necessary to complete a CURE throughout the Environmental Studies major …

Vines In The Neotropics: Phylogenomics, Biogeography And Systematics In Passion Flowers (Passiflora Subgenus Decaloba Section Decaloba), Serena Acha

Dissertations

With 600 species, Passiflora is a large, morphologically complex and broadly distributed genus in Passifloraceae that represents a major challenge to scientists interested in understanding the evolutionary history of tropical vines. Passiflora has been divided into subgenera, super sections and sections. One of the most enigmatic and species-rich (~120 spp.) groups in Passiflora is section Decaloba, which occurs in the Neotropics and is particularly diverse in Andean montane forests. In this study, we used phylogenomic and population genomic approaches to investigate the evolutionary history, biologeography, species boundaries, and taxonomy of Passiflora section Decaloba. We sampled herbarium specimens, extracted …

Conformational Polymorphism In Organic Crystals: Structural And Functional Aspects - A Review, Bidisha Sengupta, Pradeep K. Sengupta, Romans Grant1, Matthew Beasley1, Benjamin Mason1, Tanesha Love1, Larissa Barroso9, Mariela Alvarado9, M S. Zaman

Faculty Publications

Polymorphism in organic crystals involves the formation of isomeric molecular identities. It is dependent on the structural arrangement due to inter-atomic interactions, as well as external stimuli, which include temperature, visible and UV radiation. Conformational polymorphism of organic crystalline molecules is often the result of isomerism due to the twisting and turning of angular bonds. The arrangement of the atoms supports different types of bonding mechanisms (which include hydrogen bonding) within the same compound. This, in turn, results in the formation of cis/trans configurational isomers or a proton transfer species (tautomer), having different functional properties. The conformers support the flexibility …

The Right To Support: Severely Disabled Children & Their Mothers, Sheila Kathleen Jennings

PhD Dissertations

The author examines how severely disabled children and their mothers, who are usually their primary caregivers, are treated by Canadian law and policy. She identifies and analyzes deficiencies in care and other supports the state makes available to them. She further provides an analysis of the role of the state as it increasingly privatizes responsibility for supports, including unpredictable and often complex forms of care, situating them in practice, with mothers. Caregiving mothers are required to provide what comprises maternally complex care, which may be medical, neurological or psychiatric in nature. Within complex care, visible and hidden costs have been …

Ethics And Care: For Animals, Not Just Mammals, Jennifer A. Mather

Speciesism and Breed Discrimination Collection

In the last few decades, we have made great strides in recognizing ethics and providing care for animals, but the focus has been mainly on mammals. This stems from a bias of attention not only in research but predominantly in non-scientists’ attention (to ‘popular’ animals), resulting partly from discussion about and depiction of animals in publications addressed to the public. This is somewhat due to political pressure, and can result in uneven conservation efforts and biases in targets for welfare concerns. As a result, there has been a huge backlash again, with concerns about pain sensitivity and welfare in fish, …

The Anchor, Volume 133.03: November 22, 2019, Hope College

The Anchor: 2019

The Anchor began in 1887 and was first issued weekly in 1914. Covering national and campus news alike, Hope College’s student-run newspaper has grown over the years to encompass over two-dozen editors, reporters, and staff. For much of The Anchor's history, the latest issue was distributed across campus each Wednesday throughout the academic school year (with few exceptions). In recent years The Anchor moved to monthly print issues and a more frequently updated website. The Anchor is now published in print twice per academic semester. Occasionally, the volume and/or issue numbering is irregular.

Towards Completely Automated Glycan Synthesis, Matteo Panza

Dissertations

Carbohydrates are ubiquitous both in nature as biologically active compounds and in medicine as pharmaceuticals. Although there has been continued interest in the synthesis of carbohydrates, chemical methods require specialized knowledge and hence remain cumbersome. The need for development of rapid, efficient and operationally simple procedures has come to the fore. This dissertation focuses on the development of a fully automated platform that will enable both experts and non-specialists to perform the synthesis of glycans. Existing automated methods for the synthesis of oligosaccharides are highly sophisticated, operationally complex, and require significant user know-how. By contrast, high performance liquid chromatography (HPLC) …

Access To Law Or Access To Lawyers? Master’S Programs In The Public Educational Mission Of Law Schools, Mark Edwin Burge

University of Miami Law Review

The general decline in juris doctor (“J.D.”) law school applicants and enrollment over the last decade has coincided with the rise of a new breed of law degree. Whether known as master of jurisprudence, juris master, master of legal studies, or other names, these graduate degrees all have a target audience in common: adult professionals who neither are nor seek to become practicing attorneys. Inside legal academia and among the practicing bar, these degrees have been accompanied by expressed concerns that they detract from the traditional core public mission of law schools—educating lawyers. This Article argues that non-lawyer master’s programs …

Plasmodium Secretion Induces Hepatocyte Lysosome Exocytosis And Promotes Parasite Entry., Kamalakannan Vijayan, Igor Cestari, Fred D Mast, Elizabeth K K Glennon, Suzanne M Mcdermott, Heather S Kain, Alyssa M Brokaw, John D Aitchison, Kenneth Stuart, Alexis Kaushansky

Articles, Abstracts, and Reports

The invasion of a suitable host hepatocyte by Plasmodium sporozoites is an essential step in malaria infection. We demonstrate that in infected hepatocytes, lysosomes are redistributed away from the nucleus, and surface exposure of lysosome-associated membrane protein 1 (LAMP1) is increased. Lysosome exocytosis in infected cells occurs independently of sporozoite traversal. Instead, a sporozoite-secreted factor is sufficient for the process. Knockdown of SNARE proteins involved in lysosome-plasma membrane fusion reduces lysosome exocytosis and Plasmodium infection. In contrast, promoting fusion between the lysosome and plasma membrane dramatically increases infection. Our work demonstrates parallels between Plasmodium sporozoite entry of hepatocytes and infection …

Radon (222rn) Concentrations In The Touristic Jumandy Cave In The Amazon Region Of Ecuador, Felipe Alejandro García Paz, Yasser Alejandro Gonzalez Romero, Rasa Zalakeviciute

KIP Articles

This work consists of the detection and quantification of the concentration levels of radioactive gas radon-222 (222Rn) of natural origin, as well as the determination of the critical points and the estimation of the effective dose absorbed by the tourists and guides inside the Jumandy cavern in Napo, Ecuador. According to the feasibility map of uranium of Ecuador, the study area is located in one of the top-priority areas for obtaining uranium, suggesting possible radioactivity in this unstudied region. The measurements were carried out from July to October of 2017, in three different monitoring points inside the cavern. The average …

Content Release And Fusion Of Quinone-Based Liposomes: Lipid Distribution And Cleavage Symmetry Of The Quinone Headgroup At The Bilayer, Huy Huu Nguyen

LSU Doctoral Dissertations

Delivery of most conventional nanomedicines for tumor treatment is through exploiting the enhanced permeability and retention effect with limited targeting potency. Furthermore, the inability of some nanocarriers to enter the cells via endocytosis, or their limited endocytic escape restrict their applications for intracellular delivery. Liposomal carrier systems offer a solution as they are capable of precisely spatiotemporal releasing the payloads upon sensing specifically targeted environments.

In 2008, the McCarley group demonstrated an example of redox-responsive triggered release of the liposomes, named Q₃DOPE, which can potentially take advantage of elevated quinone reductase activities of hNOQ₁ in several cancers. …

Assessing The Efficacy Of Virtual Experiments In The General Chemistry Laboratory, Cory Jerome Hensen

Dissertations and Theses

As more students enroll in chemistry courses, institutions are faced with increasing costs and limited laboratory space to keep up with the demand. One solution some institutions have turned to is the incorporation of virtual experiments into the curriculum, as this can lower costs and increase the availability of laboratory space. Some institutions have offered sections that complete all of their experiments in a virtual environment, others have offered sections that alternate between a traditional hands-on experiment and a virtual experiment, and some institutions have replaced only select experiments throughout the curriculum with a virtual experiment. To begin to be …

Cortical Thickness Comparison Of Asd And Td Subjects, Jonathan Rigoberto Uriarte-Lopez

University Honors Theses

With 1 out of every 59 adolescents diagnosed with autism spectrum disorder (ASD), more research interest has been dedicated to studying why ASD individuals experience their symptoms of restricted and/or repetitive behaviors, and deficits in social interaction and communication. ASD can only be diagnosed by psychiatric evaluation of behavior, and there is a lack of reliable biomarkers for ASD to verify the diagnosis. To potentially find a reliable biomarker, we compared cortical thickness in 911 ASD subjects and 999 controls from the Autism Brain Imaging Data Exchange (ABIDE) dataset. The dataset was processed using the Developmental Cognition and Neuroimaging (DCAN) …

Statistical Methods And Validation Procedures For Spike Sorting, Michael Thomas

University Honors Theses

Spike sorting is the process of converting a recording of the electrical activity generated by neurons firing in the brain, into a representation of the timings for each distinct neuron's firing. This representation of neuronal firings, when paired with data on the subjects' perceptions or actions during the recording, can then be used to map patterns of brain activity to specific stimuli or behaviors. Here we will examine the evolution of mathematical techniques employed to tackle this problem, as well as examine a few of the still open questions.

How Urban Land Use Contributes To Inequitable Health Outcomes: An Interdisciplinary Review & Analysis, Bliss Storm Croton

University Honors Theses

Using existing literature as a basis for initial review, this paper seeks to explore the relationship between urban land use and socioeconomic status as both pertain to the prevalence of psychological health diagnoses among neighborhood residents. The purpose of this analysis is to investigate the combined literature from multiple areas of research in order to gain a more holistic, up-to-date scope of knowledge regarding how discriminatory neighborhood land use may result in poorer psychological health outcomes for urban populations. By utilizing an interdisciplinary approach, some of the locally relevant, long-term impacts of uneven development and environmental injustice are examined based …

Caring About Aftercare: Thesis Presentation Of Initial Findings, Sage B. Fuentes

University Honors Theses

While previous research has studied the impact of stigma and non-normative play within the BDSM and kink community, previous psychological research involving BDSM practitioners has not investigated the cultural practice of aftercare that tends to follow the highly sensationalized acts within the culture. The current study examines this cultural practice by giving a series of semi-structured interviews to assess the importance of aftercare and how it impacts negotiations and play. BDSM practitioners (n = 11) participated in audio recorded interviews regarding questions on identity, kink, aftercare, consent, and negotiation. 72.73% of individuals rated aftercare as mostly to largely important in …

Students’ Academic Performance And Dropout Predictions: A Review, Ahmed O. Ameen, Moshood A. Alarape, Kayode S. Adewole

Malaysian Journal of Computing (MJoC)

Students’ Academic Performance (SAP) is an important metric in determining the status of students in any academic institution. It allows the instructors and other education managers to get an accurate evaluation of the students in different courses in a particular semester and also serve as an indicator to the students to review their strategies for better performance in the subsequent semesters. Predicting SAP is therefore important to help learners in obtaining the best from their studies. A number of researches in Educational Psychology (EP), Learning Analytics (LA) and Educational Data Mining (EDM) has been carried out to study and predict …

Oral Microbiome Diversity In Chimpanzees From Gombe National Park, Andrew T. Ozga, Ian C. Gilby, Rebecca Nockerts, Michael L. Wilson, Anne Pusey, Anne C. Stone

Biology Faculty Articles

Historic calcified dental plaque (dental calculus) can provide a unique perspective into the health status of past human populations but currently no studies have focused on the oral microbial ecosystem of other primates, including our closest relatives, within the hominids. Here we use ancient DNA extraction methods, shotgun library preparation, and next generation Illumina sequencing to examine oral microbiota from 19 dental calculus samples recovered from wild chimpanzees (Pan troglodytes schweinfurthii) who died in Gombe National Park, Tanzania. The resulting sequences were trimmed for quality, analyzed using MALT, MEGAN, and alignment scripts, and integrated with previously published dental …
