Accessibility and cost savings were found as pros; while functionality and pedagogy were reported as drawbacks to mobile device …

The Revolution Will Not Be Stereotyped: Changing Perceptions Through Diversity, Annie Pho, Turner Masland

Library Faculty and Staff Publications and Presentations

Chapter 12. In this chapter, we examine the connection between increasing diversity in the library workplace and dispelling stereotypes. We explore how diversity in the academic library workforce can have positive effects in dispelling stereotypes through visibility, outreach, and education. We also want to rethink what we mean when we discuss diversity and what it entails. This is important to the process of examining library diversity initiatives and how they can fall short of complete inclusion. We also explore how activist librarians have defied the librarian stereotype and what we can learn from them. In order to create desired changes, …

Novel Roles For Actin In Mitochondrial Fission, Anna L. Hatch, Pinar S. Gurel, Henry N. Higgs

Dartmouth Scholarship

Mitochondrial dynamics, including fusion, fission and translocation, are crucial to cellular homeostasis, with roles in cellular polarity, stress response and apoptosis. Mitochondrial fission has received particular attention, owing to links with several neurodegenerative diseases. A central player in fission is the cytoplasmic dynamin-related GTPase Drp1, which oligomerizes at the fission site and hydrolyzes GTP to drive membrane ingression. Drp1 recruitment to the outer mitochondrial membrane (OMM) is a key regulatory event, which appears to require a pre-constriction step in which the endoplasmic reticulum (ER) and mitochondrion interact extensively, a process termed ERMD (ER-associated mitochondrial division). It is unclear how ER-mitochondrial …

The Spread Of Exotic Plant Species At Mount St. Helens: The Roles Of A Road, Disturbance Type And Post-Disturbance Management, Lindsey Karr

Environmental Science and Management Professional Master's Project Reports

The landscape of Mount St Helens was dramatically transformed when it erupted on May 18, 1980, creating an outstanding opportunity for ecologists to study succession following a large, intense, natural disturbance. Within the expansive (600 km²) blast area there is varied ownership and a mix of management objectives for the post-eruption landscape. On lands administered by the U.S. Forest Service, there are portions of the blast area that have been designated as a National Volcanic Monument, where the primary management objective is to allow for natural succession to proceed substantially unimpeded. In other areas outside the Monument, salvage …

Getting Plant Conservation Right (Or Not): The Case Of The United States, Kayri Havens, Andrea T. Kramer, Edward O. Guerrant Jr.

Environmental Science and Management Faculty Publications and Presentations

Effective plant conservation includes addressing basic needs such as information about species distribution and rarity; research, management, education, and training capacity to mitigate threats facing threatened species; policy and funding to support continued capacity and conservation; and, ultimately, a public that understands and supports the importance of plants and the need for their conservation. Coordination of plant conservation efforts is also needed to ensure that resources and expertise are used in a strategic, efficient, and effective manner.We argue that no country is currently getting plant conservation right; plants are becoming increasingly rare around the world. Plants are often not fully …

Environmental Science and Management Faculty Publications and Presentations

The Sydney Coordinated Adaptive Traffic System (SCATS), an adaptive signal system designed to reduce congestion, has been installed on a heavily trafficked roadway in Portland, OR. In addition to traffic performance metrics, we are investigating how this system affects roadway emissions of air pollutants. A twenty-second reduction to maximum cycle length was proposed for the SCATS system to address pedestrian delay concerns. A two-week trial period with this reduced cycle length was implemented. Travel times and roadside air pollution concentrations were monitored throughout this study period and compared to before and after periods with the current maximum cycle length. Average …

Parental Pressure, Anxiety, And Performance Among Age Group Swimmers, Timothy Michael Dasinger

LSU Master's Theses

Background/Purpose: Parents introduce children to youth sport and can increase a child’s level of enjoyment in the sport. However, parents can also place too much pressure on the child, which can lead to increased pre-competition anxiety and decreased performance (Bois, Lalanne, & Delforge, 2008; Scanlan & Lewthwaite, 1984). The purpose of this study was to examine the relationships among perceived and desired parental pressure, pre-competition state anxiety, subsequent performance, and intention to continue the sport in youth swimmers ages 9-18. Method: A sample of 43 swimmers (17 male, 26 female; M=12.8±2.6 years) on a United States Swimming (USS) sanctioned club …

Impacts Of Feeding Baleage To Beef Calves During The Backgrounding Period, Rachel Morgan Martin

LSU Master's Theses

Two hundred forty beef calves (BW = 217 ± 20.6 kg) were used to evaluate performance, blood metabolites, and rumen development from feeding bermudagrass or ryegrass and rye baleage. Calves were stratified by BW, sex, and breed and assigned to one of 12 paddocks (0.40 ha each) with 4 treatment diets and fed for a 60 d backgrounding period. Diets included: early boot stage bermudagrass hay, (BERH); early boot stage ryegrass and rye baleage (ERRG); late bloom stage ryegrass and rye baleage, (LRRG); and early boot stage bermudagrass baleage, (BERB). Calves on BERH, LRRG, and BERB had free choice access …

Access To Counsel: Psychological Science Can Improve The Promise Of Civil Rights Enforcement, Victor D. Quintanilla, Cheryl R. Kaiser

Articles by Maurer Faculty

Employment discrimination claimants in general, and racial minority claimants in particular, disproportionately lack access to legal counsel. When employment discrimination claimants lack counsel, they typically abandon their claims, or if they pursue their claims, they do so pro se (without counsel), a strategy that is seldom successful in court. Access to counsel is, hence, a decisive component in whether employment discrimination victims realize the potential of civil rights enforcement. Psychological science analyzes access to counsel by identifying psychological barriers—such as threatened social identity, mistrust in legal authorities, and fear of repercussions—that prevent employment discrimination victims from pursuing counsel. The analysis …

Obesity-Related Hormones And Metabolic Risk Factors: A Randomized Trial Of Diet Plus Either Strength Or Aerobic Training Versus Diet Alone In Overweight Participants, Allan Geliebter, Christopher N. Ochner, Carl L. Dambkowski, Sami A. Hashim

Lander College of Arts and Sciences Publications and Research

There is debate about the additive effects of exercise in conjunction with diet to treat obesity, and not much is known about the differential effects of strength versus aerobic training. This randomized controlled trial examined the effects of diet plus strength training, diet plus aerobic training, or diet only on metabolic risk factors associated with obesity. Eighty-one overweight and obese participants completed the 8-week intervention. All participants received an energy-restrictive formula diet with an energy content based on 70% of measured resting metabolic rate (RMR). Participants assigned to an exercise group trained 3 days/week under supervision. Anthropometrics and fasting hormones …

Cardiolipin Prevents Membrane Translocation And Permeabilization By Daptomycin, Tianhua Zhang, Jawad K. Muraih, Nasim Tishbi, Jennifer Herskowitz, Rachel L. Victor, Jared Silverman, Stephanie Uwumarenogie, Scott D. Taylor, Michael Palmer, Evan Mintzer

Lander College of Arts and Sciences Publications and Research

Daptomycin is an acidic lipopeptide antibiotic that, in the presence of calcium, forms oligomeric pores on membranes containing phosphatidylglycerol. It is clinically used against various Gram-positive bacteria such as Staphylococcus aureus and Enterococcusspecies. Genetic studies have indicated that an increased content of cardiolipin in the bacterial membrane may contribute to bacterial resistance against the drug. Here, we used a liposome model to demonstrate that cardiolipin directly inhibits membrane permeabilization by daptomycin. When cardiolipin is added at molar fractions of 10 or 20% to membranes containing phosphatidylglycerol, daptomycin no longer forms pores or translocates to the inner membrane leaflet. Under …

Skipping Breakfast Leads To Weight Loss But Also Elevated Cholesterol Compared With Consuming Daily Breakfasts Of Oat Porridge Or Frosted Cornflakes In Overweight Individuals: A Randomised Controlled Trial, Allan Geliebter, Nerys M. Astbury, Roni Aviram-Friedman, Eric Yahav, Sami Hashim

Lander College of Arts and Sciences Publications and Research

Eating breakfast may reduce appetite, body weight and CVD risk factors, but the breakfast type that produces the greatest health benefits remains unclear. We compared the effects of consuming a high-fibre breakfast, a non-fibre breakfast, or no-breakfast control on body weight, CVD risk factors and appetite. A total of thirty-six overweight participants (eighteen men and eighteen women) (mean age 33·9 (SD 7·5) years, mean BMI 32·8 (SD 4·7) kg/m2) were randomly assigned to consume oat porridge (n = 12), frosted cornflakes (n = 12) or a water control (n = 12) breakfast daily for 4 weeks.

Phenolic compounds are the common antioxidants that are widely found in fruits and vegetables. In this study, three varieties of potatoes and four varieties of sweet potatoes were used to examine the profiles and contents of phenolics in the raw and boiled potatoes and sweet potatoes. The Red Garnet Sweet Potato (RGSP) was the richest in phenolic content and selected to study the changes of free phenolics, total phenolic content, and antioxidant activity …

Oyster Spat Survival In Response To Hydrocarbon Contamination And Predation In Barataria Bay, Louisiana, Maria Louise Vozzo

LSU Master's Theses

Barataria Bay, in southeast Louisiana is home to productive oyster reefs that are both ecologically and economically important, but was threatened by the Deepwater Horizon oil spill in April 2010. This study was designed to determine how the oil spill affected long- and short-term oyster recruitment, and spat (juvenile oysters) cellular health. I also investigated how predators in the bay affect spat survival. Four study sites were selected in Barataria Bay: two control and two oiled, each with a low and high salinity location. To determine whether there were long-term effects of the oil spill on oyster recruitment, tiles were …

Pringle And The Nature Of Legal Reasoning, Paul Craig

Articles by Maurer Faculty

The Pringle judgment generated significant academic comment, concerning all aspects of the case. It raises, as will be seen, broader issues as to the nature of legal reasoning and the role played therein by text and background purpose or teleology.

Gunnar Beck is very critical of the CJEU, castigating it for reasoning that is said to be absurd, and accusing it of crossing the line between legal reasoning and political judgment. He is also critical of much academic analysis of the case, contending that this was too uncritical of the Court's judgment, and contending also that the interpretation of the …

Leader Benefits: Exploring How Leaders Benefit From Lmx, Jeffrey Muldoon

LSU Doctoral Dissertations

Leader Member Exchange (LMX) theory has emerged as one of the most prominent leadership theories over the last thirty years. Scholars found that subordinates with elevated levels of LMX experience higher degrees of job satisfaction and work motivation, experience lower levels of burnout and turnover intentions, and demonstrate stronger contextual and focal job performance. Yet the work outcomes for supervisors have not been heavily researched. Scholars assume, but have not demonstrated, that supervisors gain cognitive and affective benefits beyond job performance from their relationships with subordinates. These benefits are crucial because they are common to social exchange and differentiate supervisor/subordinate …

A Treatment Planning Comparison Of Volumetric Modulated Arc Therapy And Proton Therapy For A Sample Of Breast Cancer Patients Treated With Post-Mastectomy Radiotherapy, Margaret Hernandez

LSU Master's Theses

Purpose: The delivery of post-mastectomy radiotherapy (PMRT) can be challenging for patients with left-sided breast cancer due to the planning target volume (PTV) size and proximity to critical organs. This study investigates the use of protons, both passively scattered (PS) and intensity modulated proton therapy (IMPT), for PMRT in a clinically-representative cohort of patients, and quantitatively compares the predicted outcomes of volumetric modulated photon arc therapy (VMAT) to those of proton therapy to develop an evidence-based rationale for selecting a treatment modality for PMRT patients. Methods: Eight left-sided PMRT patients previously treated at our clinic with VMAT were included in …

Occurrence Of Synthetic Amino-Polycarboxylate Chelating Compounds In Oregon Surface Waters, Nathan A. Hersey

Civil and Environmental Engineering Master's Project Reports

Cation sequestering compounds are contained in many industrial, commercial and personal care products. The most widely used chelating agents, EDTA and DTPA, are commonly found in natural and industrial settings. When chelating compounds are present, the activity and transport of metal cations in the environment and the uptake of metals in natural systems can be affected. Surface water samples from across the United States were analyzed, as well as local collection and analysis of surface waters and wastewater treatment plant effluent from around Northwest Oregon. Results indicate presence of synthetic chelating compounds in areas with human activity, and absence in …

Stroke And Aphasia Quality Of Life Scale-39: Investigating Preliminary Content Validity Of Picture Representations By People With Mild To Moderate Aphasia, Lea Jane Heise-Jensen

LSU Master's Theses

Speech-language pathologists must consider the clients’ quality of life (QoL) to provide effective and meaningful evidence-based treatment (ASHA, 2005). Quality of life assessment goes beyond language impairments and is often a key part of planning intervention. However, few QoL measures exist for people with aphasia (PWA). The Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39; Hilari, 2003) is one of the few valid and reliable measures used to assess QoL in people with mild to moderate aphasia. However, the validity and reliability of the SAQOL-39 has not been established for individuals with severe aphasia who are unable to read and …
