Methodology In The Natural And Social Sciences And Its Relationship To Geography, James T. Lorell

The Geographical Bulletin

Various methodologies are utilized in science in the achievement of these goals. Wellman concludes, "in the determination of cause and effect relations, scientific methods are indispensable, but there is no one scientific method which is inherently superior to others. We are gradually coming to realize that there is no one best method for all problems, but rather that research procedure calls for the finding of a blend of methods that is adapted to our particular problem "2

Supporting Higher Level Mental Skills In Early Childhood Education, Paul J. Johnaon

Graduate Teacher Education

The early childhood years established a critical developmental period during which foundational cognitive, social, and emotional skills were cultivated (Center on the Developing Child at Harvard University, 2011). Research highlighted the significant role of experiences during this stage of life in shaping children's readiness for school and long-term academic, social, and emotional outcomes (Center on the Developing Child at Harvard University, 2011). Among these foundational skills, executive function (EF) and self-regulation (SR) were recognized as essential for enabling goal-oriented behavior, emotional management, and problem-solving (Morgan et al., 2016). The increasing emphasis on academic rigor in early childhood education led to …

Clinical Guidelines For The Perioperative Management Of Patients With Aortic Stenosis Undergoing Noncardiac Surgery, Owen Diehl

Doctor of Nursing Practice Scholarly Projects

Aortic stenosis (AS) is a common valvular disorder that causes left ventricular (LV) outflow obstruction. The prevalence of AS may increase with the aging population and the widespread availability of diagnostic capabilities like echocardiography. With the increasing patient population diagnosed with AS, the chance of encountering these patients during noncardiac surgery (NCS) increases. Performance of anesthesia is challenging in patients with AS due to the pathophysiological consequences of AS and the hemodynamic changes associated with anesthesia. The patient with AS presenting for NCS is at an increased risk of perioperative major adverse cardiac events (MACEs). This project aimed to determine …

Disciplinary Literacy In Preschool Classrooms, Mckenna Beam

Graduate Teacher Education

The research questioned the potential impact disciplinary literacy may have on academic growth in early childhood classrooms and considered how preschool teachers can implement developmentally appropriate practices focusing on disciplinary literacy to support academic readiness skills. Schools emphasize a need for early intervention in the math and literacy domains to combat the academic achievement gap, but Chapin (2006) recognized a need for early intervention in the science and social studies domains as well. With this knowledge in mind, specific developmentally appropriate methods for integrating science, social studies, music, and art instruction in preschool classrooms were highlighted. Systemic methods of implementing …

Assessing Implications Through General Strain Theory: Comparative Analysis Of Crime Rates In Flint And Pontiac Michigan, Jennifer Harrison

Honors Projects

Flint, Michigan suffered a city water change from the Great Lake’s Lake Huron water pipeline to an old system using the Flint River as the main source of water (Reuben, et al., 2022). The change took place in an effort to make budget cuts (Denchak, 2024). The switch occurred before checking the safety of the pipes, which were severely corroded (Reuben, et al., 2022). Lead poisoning and Legionnaires disease spread through the Flint community and the water was visibly not safe for use (Reuben, et al., 2022). The people of Flint experienced stress that they could not control. They feared …

Make Some Noise: The Intersection Of Music Therapy And Classroom Management, Erica Ewell

Expressive Therapies Theses

This literature review defines and explores the themes at the intersection of music therapy and mental health counseling techniques and general education practices for classroom management. This work explores how general education teachers, who are not therapists or musicians, might use music to engage students so that their classrooms feel safe (physically and emotionally), productive, and ideally, fun.

Role Of Fluid-Structure Interactions In Mechanosensation During Hovering Flapping Flight, Menglong Lei, Chengyu Li

Faculty Scholarship

Insect wings, known for their intricate structure and function, inherently deform during flapping motion. These deformations can be classified into chordwise cambering, spanwise bending, and root-to-tip twisting, arising from non-uniform venation distribution, aerodynamic loading, and wing inertia. Crucially, such deformations play a vital role in enhancing both aerodynamic performance and mechanosensory function. To investigate the complex interplay between wing structure, unsteady aerodynamics, and mechanosensation, we developed a fully coupled three-dimensional fluid-structure interaction (FSI) solver. This framework integrates an in-house Navier-Stokes equations solver for resolving the flow field with the open-source Vega FEM code to solve the solid structure dynamics. Our …

Theoretical Proof Of And Proposed Experimental Search For The Ground Triplet State Of A Wigner-Regime Two-Electron ‘Artificial Atom’ In A Magnetic Field, Marlina Slamet, Viraht Sahni

Publications and Research

It is experimentally established that there is no ground triplet state of the natural He atom. There is also no exact analytical solution to the Schrödinger equation corresponding to this state. For a two-dimensional two-electron ‘artificial atom’ or a semiconductor quantum dot in a magnetic field, as described by the Schrödinger–Pauli equation, we provide theoretical proof of the existence of a ground triplet state by deriving an exact analytical correlated wave function solution to the equation. The state exists in the Wigner high-electron-correlation regime. We further explain that the solution satisfies all requisite symmetry and electron coalescence constraints of …

Evaluation Of Tree Legumes Species At Different Agroclimatic Zones Of Indonesia, Mas'ud Panjaitan, R Jessop, W W. Stur

IGC Proceedings (1977-2023)

The population of Indonesia is over 145 million and more than 56 % of them earn their living from agriculture (Bi. Stat. Ind., 1983). A major problem in the development of improved animal production has been the shortage of feed and the generally low nutritive value of tropical forages which limit livestock pro­duction in Indonesia (Asian Agriculture Survey, 1969). The production of feed of adequate quality for ruminants is an important consideration particularly for small holders. In many situations, nitrogen fixing legume trees can be used as a high protein feed supplement which improves the utilization of grasses and crop …

Utilization Of Native Mediterranean Fodder Trees By Dairy Goats, M Meuret

IGC Proceedings (1977-2023)

Few data are available on utilization of fodder trees and shrubs by lactating goats. In most cases, predictions of animal performances on the basis of recommendations obtained from standard reference trials, do not correspond with production results achieved on the farm. Using measurements in digesti­bility cages and on rangelands (chromic oxide marker), we recorded intake, apparent digestibility of diets and perform­ances of goats well used to rangelands and browsing fresh oak foliage (Quercus ilex and Quercus pubescens).

Phenols As Defensive Compounds In Birch (Betula Spp.) Metabolism Of Platyphylloside In Goats, Rabbits And Hares, R T. Palo, G Iason, P G. Knutsonn

IGC Proceedings (1977-2023)

Herbivores of the boreal forest like moose (Alces alces), hares (Lepus spp.) and birds (Tetranoidae) use birch as a major feed source. The tree is of medium preference to the animals and is low in available nutrients for most of the year. Apart from a high amount of lignified cell walls it also contains con­siderable amounts oflow molecular phenolic substances (Palo, 1984). A herbivore feeding on birch could thus be excepted to ingest large amounts of phenols. These are in general enough fat soluble to enter animal cells expected to ingest large amounts of …

Forage Production And Nutritive Value Of Leucanea Leucoephala In Southern Puerto Rico, L E. Tergas, R Milton Martinez, A V. Mendez Cruz

IGC Proceedings (1977-2023)

Leucaena leucocephala (L.) is a perennial schrub native to Mexico, Central America and the Caribbean, considered by investigators as a valuable forage legume because of its capacity for high production of digestible forage with a high protein content and tolerance to drought in semiarid regions with annual rainfall less than 1,000 mm (Skerman, 1977). The soil fertility of the semiarid region in southern Puerto Rico is adequate, but rainfall distribution is limiting for forage production and nutritive value. There is a demand for a suit­able and inexpensive source of high quality forage to improve the diet of the grazing cattle …

Effect Of Chemical Composition Of Roughages On Their Degradation Characteristics In The Rumen And Their Relationship With The < In Vitro > Organic Matter Digestibility, S Lopez, Dolores Carro, J S. Gonzales, Conchita Carpintero

IGC Proceedings (1977-2023)

The microbial fermentation of feeds in the reticulo-rumen allows ruminants the utilization of feeds with amounts of cell wall components, i.e. roughages. This rumen fermentation can be affected by the feed chemical composition and numerous techniques have been developed for its determination (Van Soest, 1982). The objective of the present work is to investigate the effect of the chemical composition of forages preserved under differ­ent methods on their degradation characteristics in the rumen determined by the « in sacco » method and to study the rela­tionships between the « in vitro» organic matter digestibility (IVOMD) and the rumen degradability.

Rumen Degradation Of Various Grass Species At Different Stages Of Growth, L J. Halliday

IGC Proceedings (1977-2023)

The species and cultivars sown depends on the farming sys­tem practiced. These developing swards are however, always invaded by native species including Agrostis, Paa and Festuca spp. which are generally referred to as 'weed' grasses. While the merits of Lolium spp. are well documented (Minson et al. 1960; Norton, 1982) information on the weed grasses is limited (Hag­gar, 1976). The potential for milk and meat production is dependent on the supply of utilizable nutrients to the animal's tissues which in turn is largely governed by the ability of rumen microbes to degrade plant cell walls. Although the degradability of dry …

Apparent Digestibility, Dynamics Of Rumen Fermentation And Sites Of Digestion Of Hays Of Leucaena Leucocephala (Lam) De Wit Cv. Peru, N M. Rodreiguez, I Borges

IGC Proceedings (1977-2023)

Protein deficiency, among others, is a common problem for livestock production in tropical regions. The use oflegumes has been suggested as a solution and Leucaena leucocephala has shown a great potential due to its capacity of nitrogen (N) fix­ation and dry matter (DM) production (NAS, 1984). However, very little is known about its nutritive value regarding its protein-energy balance and the process of digestion. The present work aimed the evaluation of the nutritive value of hays of Leucaena leucocephala cut at two stages of growth, through trials of apparent digestibility, dynamics of rumen fer­mentation and partition of digestion.

In Situ Degradation Of Cell Wall Neutral Sugars Of Normal And Brown Midrib Sorghum X Sudangrass Hybrids, K J. Moore, J O. Fritz, E H. Jaster

IGC Proceedings (1977-2023)

The nutritive value of forage for ruminants is limited by the digestibility of the complex polysaccharides cellulose and hemicellulose by rumen microbes. In grasses, the polysacchar­ide fraction of the cell wall is composed largely of polymers of neutral sugars and to a lesser extent uronic acids. Cellulose is a high molecular weight linear polymer of B-1 ➔ 4) linked D­gluco-pyranose units. Hemicellulose is a complex mixture of linear and branched-chain heteropolymers containing xylose, arabmose, mannose, galactose, glucose, and uronic acids (Van Soest, 1982). Lignification of the cell wall is a primary factor limiting the digestion of cell wall polysaccharides. Close …

Feed Evaluation Using Mobile Dacron Bags And Influences Of The Diet Composition, H Anzola, F N. Owens

IGC Proceedings (1977-2023)

The Mobile Nylon Bag (MNB) technique has been used successfully in protein nutrition studies with swine (Sauer et al., 1983) to determine amino acid availability from protein in specific feedstuffs. Canadian researchers also have tested this technique to predict site of digestion in ruminants (Kirkpatrick and Kennelly, 1987). Differences in small intestinal digestion may explain why animal responses differ to dietary protein sources which have similar ruminal escape values (Owens, 1986). The MNB holds promise to appraise the intestinal avail­ability of undegraded dietary protein though further develop­mel).t and testing are needed. The objective of this experiment was to examine the …
