Insights From Two Decades Of P-12 Engineering Education Research, Cary I. Sneider, Mihir K. Ravel

Journal of Pre-College Engineering Education Research (J-PEER)

The 21st century has seen a growing movement in the United States towards the adoption of engineering and technology as a complement to science education. Motivated by this shift, this article offers insights into engineering education for grades P-12, based on a landscape review of 263 empirical research studies spanning the two decades from January 2000 to June 2021. These insights are organized around three core themes: (1) students’ understandings, skills, and attitudes about engineering and technology; (2) effective methods of P-12 engineering education; and (3) benefits of P-12 engineering education. The insights are captured in the form of evidence-based …

Development And Validation Of A Survey Instrument Targeting Teachers’ Perceptions Of The Scope Of Engineering, Jacob Pleasants

Journal of Pre-College Engineering Education Research (J-PEER)

Around the world, pre-college teachers are increasingly being called upon to address engineering, often as part of science instruction. Teachers are typically tasked with engaging students in authentic engineering design activities to promote students’ development of design practices while deepening their knowledge of relevant science concepts. Planning and implementing engineering experiences that authentically reflect the field require that teachers hold accurate perceptions of what engineering is, how it works, and how it is related to yet distinct from science. As teacher education and research efforts in this area grow, there is a need for high-quality instruments that elicit key aspects …

Advances In Rhizobial Research – Progress Priorities In Temperate Areas, Angela Sessitsch

IGC Proceedings (1977-2023)

Rhizobia are well known for their capacity to establish a symbiosis with legumes. During this symbiosis the bacteria inhabit root nodules where they reduce atmospheric nitrogen and make it available to the plant. Biological nitrogen fixation (BNF) is an important source of nitrogen and the various legume crops and pasture species often fix as much as 200-300 kg nitrogen per hectare (Peoples et al., 1995). Globally, symbiotic nitrogen fixation has been estimated to amount to at least 70 million metric tons of nitrogen per year (Brockwell et al., 1995). Furthermore, in many cases nitrogen fertilizers are not efficiently used by …

The Legume – Rhizobia Symbiosis. Does It Vary For The Tropics Relative To The Mediterranean Basin?, J. G. Howieson, A. Mcinnes

IGC Proceedings (1977-2023)

Symbiotic N fixation from legumes is one of the most important biological processes on the planet. It currently provides the majority of the N requirement in agriculture, yet will have to double if cereal crop production is to meet world demand by 2020 (Kennedy and Cocking 1997). To effectively harness the value of biological N fixation from legumes we need to more fully understand G² x E; where G refers to the genotypes of both the legume (G_l) and its microsymbiont (rhizobia; G_r), and E refers to the edaphic environment in which the symbiosis is …

Advances In Forage Legumes: Shrub Legumes, M. H. Shelton

IGC Proceedings (1977-2023)

Forage tree legumes benefit agriculture through their multi-purpose contributions to livestock feeding, to productivity of farming systems, and to protection of the environment.

Of the several hundred forage tree legume species regarded as having potential for forage only c. twenty are in common use. These are listed together with their agroecological range and tolerance of adverse environments including acid soils, cool temperatures, low rainfall, poor drainage and high salinity. The value of many species to ruminants is limited due to low nutritive value arising from low protein availability and low acceptability caused principally by high condensed tannin content. Only 10 …

Alfalfa, J. H. Bouton

IGC Proceedings (1977-2023)

Cultivated alfalfa or lucerne (Medicago sativa spp. sativa) is the most important forage legume in the world with approximately 32 million hectares cultivated mainly in the temperate regions of both the northern and southern hemispheres. Intensive research has been conducted on the management and physiology of the crop and a major seed industry has developed world wide. Since insect and disease pests are numerous in alfalfa, development of cultivars with the proper fall dormancy and a broad genetic base for pest resistance has been pursued in order to provide increased adaptation, persistence, and yield. There has been a …

Carbon And Nitrogen Isotopic Discrimination In Alfalfa For High Yield And Quality Forage, W. S. Oliveira, P. P. A. Oliveira, M. Corsi, S. M. Tsai

IGC Proceedings (1977-2023)

Biological nitrogen fixation and assimilation of CO₂ can be indirectly monitored in alfalfa (Medicago sativa L.) through the variation of the stable N and C isotopes in the plant (Δ values). Such measurements result in a simple, non-destructive and reliable method for identification of alfalfa cultivars of high yield and nutritional quality. A program for selection of 12 alfalfa cultivars under field and controlled conditions (lysimeters) included determination of biomass and N accumulation. Under controlled conditions yields ranged from 1.77 to 2.47 ton/ha/month (Pioneer 5312 and WL-605) and N2-fixed varied from 77.43 to 84.01% for total N (Brazilian …

Power Reclaimed And Given: Female Passivity And Agency In Harris, Brand, And Smith, Annika Northrop

Journal of Interdisciplinary Undergraduate Research

The paper “Power Reclaimed and Given: Female Passivity and Agency in Harris, Brand, and Smith” explores representations of women in art in Claire Harris’ “After Image,” Dionne Brand’s “Blues Spiritual for Mammy Prater,” and Ali Smith’s How to be both. Harris’ poem depicts a woman, who is the subject of a male photographer’s photos and who has been objectified and relegated to passivity by the photographer, in the active process of reclaiming the power to create her own identity. Brand’s poem shows Mammy Prater as a woman who, although formerly subjugated and abused, has already reclaimed that power; in …

Effects Of Freshwater Input On Nutrient Loading, Toxic Cyanobacteria Bloom Development And Cyanotoxin Production In Lake Pontchartrain Estuary, Louisiana, Callie L. Snow

LSU Master's Theses

Estuaries in the northern Gulf of Mexico (GoM) are undergoing profound alterations due to changes in climate and implementation of coastal restoration activities and these may lead to the increasing frequency of harmful algal blooms (HABs). The introduction of large volumes of nutrient-rich, fresh Mississippi River water into nutrient-poor Lake Pontchartrain Estuary is known to substantially change the chemistry and ecology of the estuary, and warm temperatures paired with the persistent nutrient loading into the estuary supports the proliferation of potentially toxic cyanobacteria blooms (CyanoHABs). Throughout 2019, a long-term opening of the Bonnet Carré Spillway (BCS), initially from February to …

Hemp Microgreen Mineral Content, Cannabinoids, Total Phenolics, And Antioxidants, Cheston T. Schayot

LSU Master's Theses

Hemp (Cannabis sativa) L. microgreens were grown to 7 and 12 days with and without supplemental lighting and/or fertilizer. The principal macronutrient found in hemp microgreens was nitrogen (N), followed by potassium (K), phosphorus (P), magnesium (Mg), calcium (Ca), and sulfur (S). The principal micronutrient found in hemp microgreens was iron (Fe), followed by manganese (Mn), zinc (Zn), boron (B), and copper (Cu). Hemp microgreens were similar to other commonly grown microgreen species in minerals except for P and Mg, where they could potentially be an excellent source, and Zn, where they fell below previously reported amounts. The …

Response Of Roseau Cane (Phragmites Australis) To Two Biotic Stresses: Hyalopterus Pruni And Bipolaris Yamadae, Heather E. Cizek

LSU Master's Theses

Roseau cane (Phragmites australis) is considered an invasive plant because of its ability to replace native plant species. However, in Louisiana it plays an important role protecting coastal infrastructure and being part of the marsh ecosystem in the lower Mississippi River Delta. In recent years, Roseau cane has been affected by a die-off, a problem that has also been reported in some European countries. Possible biotic and abiotic factors that have been associated with the die-off include scale insects, climate change, pollution, salinity levels, and pathogens.

In this research, the individual and combined effect of a foliar disease …

3-Dimensional Structural Determination Of Epidermal Growth Factor-Like Repeat 27 From Mouse Notch1 Using Nuclear Magnetic Resonance Spectroscopy, Justin Grennell

LSU Doctoral Dissertations

NOTCH1 has been associated with a variety of human ailments, such as cancer and heart disease. NOTCH1 is a transmembrane protein that contains 36 epidermal growth factor-like (EGF) repeats, which facilitate cell signaling by binding proteins on neighboring cells. Each repeat contains about 40 amino acids and has to be folded in a specific manner to function properly. The amino acid sequence, carbohydrate pattern, and calcium-binding sites of EGF-like repeats vary, but the pattern along the 36-repeat chain is conserved. The Abruptex region (EGF24-29) of NOTCH1 is a highly glycosylated (having undergone sugar addition) and flexible region, which gained its …

Can Open-Mindedness Be Primed? An Investigation Into Creativity, Openness To Experience, And Open-Mindedness Among College Students With Implications For Counselors, Alex Gallimore

Journal of Interdisciplinary Graduate Research

With an ever-diversifying population, open-mindedness regarding an individual’s values and beliefs is important, especially for counselors. This study hypothesized that creativity could be a means to increase one’s open-mindedness. Utilizing a quasi-experimental design, this study examined the impact of a creative task on participants’ open-mindedness. Additionally, a correlation was sought between open-mindedness and the Big Five personality trait of Openness to Experience as well as a comparison between participants studying for careers in the helping professions (counselors, psychologists, and social workers) and all other participants. Two hundred and forty-four students at a small, private university participated. Results found no significant …

A 6-Cpg Validated Methylation Risk Score Model For Metabolic Syndrome: The Hypergen And Goldn Studies, Bertha A. Hidalgo, Bre Minniefield, Amit Patki, Rikki Tanner, Minoo Bagheri, Hemant K. Tiwari, Donna K. Arnett, Marguerite Ryan Irvin

Epidemiology and Environmental Health Faculty Publications

There has been great interest in genetic risk prediction using risk scores in recent years, however, the utility of scores developed in European populations and later applied to non-European populations has not been successful. The goal of this study was to create a methylation risk score (MRS) for metabolic syndrome (MetS), demonstrating the utility of MRS across race groups using cross-sectional data from the Hypertension Genetic Epidemiology Network (HyperGEN, N = 614 African Americans (AA)) and the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN, N = 995 European Americans (EA)). To demonstrate this, we first selected cytosine-guanine dinucleotides …

Predicting Thermal Responses Of An Arctic Lake To Whole-Lake Warming Manipulation, Qunhui Zhang, Jiming Jin, Phaedra Budy, Sarah E. Null, Xiaochun Wang, Casey A. Pennock

Watershed Sciences Faculty Publications

We investigated how lake thermal processes responded to whole lake warming manipulation in an arctic lake through observations and numerical modeling. The warming manipulation was conducted by artificially heating the epilimnion as a proxy for climate warming. We performed numerical modeling with an improved lake scheme based on the Community Land Model (CLM). We simulated a control run (CTL) without warming and a warming manipulation simulation (WARM). Results indicated WARM accurately captured observed temperatures where water stratification was extended in time, and water stability was strengthened. Two additional sensitivity tests with different warming onset dates and of the same warming …

Doomed To Fail: Ag-Gag Laws And The Canadian Charter, Samantha Lynne Skinner

LLM Theses

In late 2019, ag-gag laws began being introduced in Canada. Ag-gag laws are named for their intended effect of gagging activists from exposing the realities of the animal agriculture industry. Animal activists seek to gather and publicly disseminate information using means of bearing witness, undercover investigations, and civil disobedience. Ag-gag laws originated in the US in the 1990s, but saw a revival in the 2010s. In the US, animal law organizations such as the Animal Legal Defense Fund have been successfully challenging the constitutionality of ag-gag laws, with courts in six states finding ag-gag laws to violate the First Amendment …

Relating Multivariate Shapes To Genescapes Using Phenotype-Biological Process Associations For Craniofacial Shape., Jose D Aponte, David C Katz, Daniela M Roth, Marta Vidal-García, Wei Liu, Fernando Andrade, Charles C Roseman, Stephen A Murray, James Cheverud, Daniel Graf, Ralph S Marcucio, Benedikt Hallgrímsson

Faculty Research 2021

Realistic mappings of genes to morphology are inherently multivariate on both sides of the equation. The importance of coordinated gene effects on morphological phenotypes is clear from the intertwining of gene actions in signaling pathways, gene regulatory networks, and developmental processes underlying the development of shape and size. Yet, current approaches tend to focus on identifying and localizing the effects of individual genes and rarely leverage the information content of high-dimensional phenotypes. Here, we explicitly model the joint effects of biologically coherent collections of genes on a multivariate trait - craniofacial shape - in a sample of n = 1145 …

Relief And Reward Drinking Across Time In Community And Treatment-Seeking Samples, Julia E. Swan

Psychology ETDs

Classifying people with alcohol use disorder into homogenous groups based on observed characteristics (i.e., phenotypes) could match individuals to specific treatments. The reward-relief phenotype classifies individuals based on whether they drink to enhance rewarding experiences and/or to relieve negative states. The current study is a secondary data analysis of a community sample of non-treatment seeking heavy drinkers (n = 189) and two randomized clinical trial samples of individuals with alcohol use disorder (n = 1726, 1383) that aimed to determine if the reward-relief phenotype is identified across samples, is stable over time, and predicts long-term alcohol consumption and consequences. We …
