A History Of Land Tenure In The Ixil Region, Elaine Elliott

Maya America: Journal of Essays, Commentary, and Analysis

After the Spanish conquest, the IxilMayainitially remained less affected than more centrally located groups. However, dramatic changes occurred due to Guatemalan national government laws in the late 1800s which allowed claims on “vacant land”. Maya on those lands quickly adapted, claiming the areas where they had lived for over a millennium. The government favored large landowners who contributed to the national economy with export crops, particularly coffee. In the 1950s era of land reform, small farmers briefly obtained land, something quicklyreversed with the overthrow of the national government, accused of communism for these reforms. Conflict escalated when a leftist guerrilla …

Mathematicians’ Beliefs, Instruction, And Students’ Beliefs: How Related Are They?, Rachel Rupnow

Faculty Articles, Papers, and Other Scholarship

It is generally accepted that teachers’ beliefs impact their instructional choices, but characterizations of that relationship are limited in college settings. Furthermore, examinations of instructor beliefs, instruction, and student beliefs together in one setting are rarely described. Based on interviews with two Abstract Algebra instructors, classroom video from three units of instruction, and survey and interview data from students in the classes, this paper examines instructors’ stated beliefs, ways these beliefs manifested in their teaching, and students’ beliefs across the course. Both instructors made curricular choices clearly aligned with their stated views of the nature of mathematics, learning, and teaching. …

Experiences Of African American Students In Pre-Licensure Schools Of Nursing: A Qualitative Descriptive Study, Barbara Jean White

Dissertations

Despite more than 40 years of research and governmental support, African Americans continue to be underrepresented in the nursing profession compared to the population it serves. Though some progress has been made over the past 20 years, the American Nurses Association (ANA), American Association of Colleges of Nursing (AACN), National Black Nurses Association (NBNA) and Institute of Medicine (IOM) continue to identify increasing diversity as a disciplinary priority. Further understanding of the experiences of African American nursing students is needed to inform decisions about recruitment, retention and successful matriculation of these students. This qualitative descriptive study focused on understanding the …

Open Access Publications

Mass administration of ivermectin (IVM) has significantly reduced onchocerciasis prevalence, intensity, and morbidity in most endemic areas. Most IVM clinical trials were performed long ago in persons with high-intensity infections that are uncommon in West Africa today. This cohort treatment study recruited participants from a hypoendemic area in eastern Ghana to reevaluate the efficacy and tolerability of IVM with a special focus on the kinetics of microfilaria (Mf) clearance. Mf in the skin and anterior chambers (AC) were assessed by skin snip and slit lamp examinations at baseline and at 3 and 6 months after treatment with IVM 150 μg/kg. …

Seasonal Fish Communities In Three Northern California Estuaries, Katherine Osborn, Tim Mulligan, Andre Buchheister

Western North American Naturalist

The majority of Northern California estuaries are small, flooded river valleys that are largely unstudied due to their small sizes. Yet these estuaries serve as important nursery areas for many marine fish species, including rockfish, flatfish, smelt, and herring. In addition, they are vital to anadromous species such as Chinook Salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss). Some of these small estuaries gained protection with the completion of California’s Marine Protected Area (MPA) network in 2012. From June 2014 to June 2016, we sampled the summer and winter fish communities in 3 estuaries: the Big River …

Effects Of Exogenous Ketone Therapy On Performance, Cardiorespiration, And Seizure Genesis During Exposure To Hbo2 In The Sprague Dawley Rat, Nicole M. Stavitzski

USF Tampa Graduate Theses and Dissertations

Hyperbaric oxygen (HBO2) is used for clinical HBO2 therapy and in undersea and aerospace medicine. HBO2 is a humanmade extreme environment and protracted exposures can cause several adverse physiological effects on the body. For example, HBO2 increases the partial pressure of oxygen (PO2) in the body leading to redox stress. Redox stress is, in part, a cause of oxygen toxicity that manifests as seizures in its most severe form (central nervous system oxygen toxicity, CNS-OT). This dissertation focuses on strategies to be employed specifically for the warfighter breathing HBO2. Currently, the only way to prevent CNS-OT is to lower the …

IGC Proceedings (1977-2023)

Several maize (Zea mays) hybrids, including three transgenic hybrids containing Bacillus thuringiensis (Bt) enzymes (Bt-maize hybrids), were planted in a field study. Mature, midgestation, beef cows (Bos tarus) strip-grazed post-harvest residues as paddocks over 126 days. Body condition-scores and weights were monitored. Forage yield, weathering losses and forage composition were monitored on grazed and ungrazed areas. Forage selection and intake were estimated. Grain yields, dropped grain, initial crop residue concentrations of dry matter (DM), organic matter (OM) and in vitro digestible organic matter (IVDOM) yields were similar among hybrids. Hybrids varied in infestation of maize borers, …

Supplementation Of Temperate Pastures, D. H. Rearte, G. A. Pieroni

IGC Proceedings (1977-2023)

Generally in temperate regions, beef and milk were produced on extensive systems with forage from perennial pasture and natural grassland being the main component of animal diet. Supplementation on pasture was usually applied strategically to supply nutrients to grazing cattle only when forage availability was not enough to satisfy animal’s requirements. At present beef and dairy production systems have become more intensive and even when forage from pasture continue being the main component of the diet higher level of different type of supplement are fed to the animals. Intensive systems are characterized by a higher stocking rate capable of consuming …

Feeding Of Conserved Forage - Implications To Grassland Management And Production, C. W. Holmes, P. N. P. Matthews

IGC Proceedings (1977-2023)

This review will focus on the use of conserved forages in pastoral dairy farm systems; especially on their conservation as an aid to good grazing management during periods of rapid pasture growth, and on their consumption as an aid to good feeding management and grazing management during periods of slow pasture growth. Conservation of pasture, in order to move it from one time to another later time, always involves “costs”, either financial expenditure or physical losses (of dry matter/quality) or both, which must be evaluated in the whole system.

Most of the data is drawn from New Zealand and Australia, …

Supplementation Of Lactating Cows Grazing Stargrass (Cynodon Nlenfuensis Var. Nlenfuensis) With Conjugated Linoleic Acid: Effects On Persistency And Estimated Net Energy Balance, S. R. Medeiros, D. E. Oliveira, L. J. M. Aroeira, M. Mcguire, D. P. D. Lanna

IGC Proceedings (1977-2023)

Thirty crossbread cows grazed stargrass (Cynodon nlenfuensis var. nlenfuensis) receiving 4kg/d of a supplement formulated to provide 115% of metabolizable protein requirements from the 4^th to the 11^th week of lactation. The cows received either 150g/head/day of Megalac (Control) or 150g/head/day of a Ca-protected conjugated linoleic acid (CLA, Church & Dwight). Residual effects of treatment were evaluated in weeks 12^th and 13^th. Milk production increased in CLA treated cows (P< 0.05). CLA decreased milk fat content (P< 0.0001) and yield (P< 0.01). Protected CLA increased protein content (P< 0.01) and yield (P< 0.01). The CLA residual effect on milk fat ends within one week after withdrawal but the benefits on milk yield and total solids production continued, due to the increased persistency. The estimated energy balance and intake were not greatly affected by treatment, as treated cows had higher milk volume and had higher protein productions.

Women’S Experiences In Religious Tourism: An Investigation Into Women’S Involvement In Sabarimala Pilgrimage, Kerala, Shyju P.J., A. Vinodan, S. Meera, Jithendran Kokkranikal

International Journal of Religious Tourism and Pilgrimage

Preparations for the Sabarimala pilgrimage involves devotees observing a 41 day period of austerity (vrata) during which they practice an ascetic life. Women between the age of 10 and 50 do not visit the shrine at Sabarimala due to long-established customs. However, women do play an important role during the 41-day austerity observed by family members preparing for the pilgrimage, which could be described as a non-participant involvement in the pilgrimage. While there have been many studies on the spiritual and secular experiences of pilgrims, research on this unique form of non-participant involvement in pilgrimages is not found especially in …
