Culturally And Linguistically Diverse Family Perspectives On Home-School Connections And Family Engagement: A Case Study Of Four Middle Class Latin American Families, Janet Elizabeth Pierce Clark

Dissertations, Theses and Capstone Projects (Full IR Collection)

The purpose of this case study was to explore the context, perceptions, and understandings of school-home connections and family engagement of four middle class Latin American families who have children in U.S. public schools. Because family engagement with schools correlates with student success, the participants’ perspectives were examined in depth. The study was guided by two major research questions and associated sub questions:

1. How do four middle class families from Latin America perceive that their child’s school makes efforts to connect with them?
a. What factors contribute to the development of connectedness between home and school for four middle …

Optimisation Of Accelerated Solvent Extraction Of Antioxidant Compounds From Rosemary (Rosmarinus Officinalis L.), Marjoram (Origanum Majorana L.) And Oregano (Origanum Vulgare L.) Using Response Surface Methodology, M. Hossain, Catherine Barry-Ryan, Ana Belen Martin-Diana, N. Brunton

Articles

The present study optimised the accelerated solvent extraction (ASE) conditions (Dionex ASE® 200, USA) to maximise the antioxidant capacity of the extracts from three spices of Lamiaceae family; rosemary, oregano and marjoram. Optimised conditions with regard to extraction temperature (66–129 °C) and solvent concentration (32–88% methanol) were identified using response surface methodology (RSM). For all three spices results showed that 129 °C was the optimum temperature in order to obtain extracts with high antioxidant activity. Optimal methanol concentrations with respect to the antioxidant activity of rosemary and marjoram extracts were 56% and 57% respectively. Oregano showed a different response to …

Homocysteine: A Potential Molecular Link Between Alzheimer's Disease And Type 2 Diabetes Mellitus, Cyndel Carreau

Biological Sciences

In order to elucidate some of the mechanisms through which Alzheimer’s disease (AD) and Type II Diabetes Mellitus (T2DM) are linked, this study investigated the effects of elevated plasma homocysteine levels – a risk factor for AD – in a rat model of T2DM. Both elevated plasma homocysteine levels and T2DM are associated with cognitive deficits and are recognized as strong risk factors for the development of AD. The present experiment examined the effects of diet-induced hyperhomocysteinemia on the development of cognitive impairments and insulin-resistance, as well as on the insulin signaling cascade, in a diet-induced obese rat model of …

The purpose of this study was to identify and describe unique classes of youth based on their perception in a variety of physical activity and sedentary behaviors. Methods: Latent class analysis was used to characterize segments of youth based on patterns of self-reported and accelerometer-measured participation in 12 behaviors. Children and adolescents (N =720) from 6th-11th grade were included in the analysis. Differences in class membership were examined using multinomial logistic …

Getting Into The Field, Jay A. Mitchell

Journal of Food Law & Policy

A group of students enrolled in a law school clinic wanders through a large farmers' market. They stop to chat with the proprietors of a farm that has sold vegetables at the market for many years. They visit with a cheesemaker and an apple grower. A second group learns about the economic costs of organic production from a farmer and talks with an olive oil producer. Both sets of students seem unusually attentive to their surroundings. That may be because the first group helped the sponsor of the market rework the market's rules and regulations, and the second developed a …

Greenwashing The Organic Label: Abusive Green Marketing In An Increasingly Eco-Friendly Marketplace, Greg Northen

Journal of Food Law & Policy

The green wave of environmental advertising among organic food producers, distributors, and retailers begun during the 1990s has become an all-out green tsunami. The organic food market is the fastest growing segment of the American food industry. Consumers are increasingly becoming aware of the impact their purchases have on several environmental issues. As a result, those consumers are becoming more aware of their spending power and are willingly altering their buying practices to purchase from companies that emphasize environmental responsibility. In fact, some retailers' inventory is already being scanned for alternative green products by their customers' iPhones because, guess what, …

Food Entrepreneurs And Food Safety Regulation, Nina W. Tarr

Journal of Food Law & Policy

It is a bucolic scene: local food growers and producers chatting with consumers who come back each week to participate in a direct and continuing conversation about food with someone they know, and to engage in commerce. This illusion of simplicity masks the ever-growing morass of conflicting, complicated, and expensive regulatory oversight that undermines the local food movement by creating barriers between producers and consumers. Those creating and implementing food policy in the United States are facing a fundamental dilemma of how to reconcile the local food movement with regulations designed to address concerns about food safety.

The History And Future Of Genetically Modified Crops: Frankenfoods, Superweeds, And The Developing World, Brooke Glass-O'Shea

Journal of Food Law & Policy

In a 1992 letter to the New York Times, a man named Paul Lewis referred to genetically modified (GM) crops as "Frankenfood," and wryly suggested it might be "time to gather the villagers, light some torches and head to the castle." Little did Lewis know that his neologism would become the rallying cry for activists around the world protesting the dangers of genetic engineering. The environmental activist group Greenpeace made great use of the "Frankenfood" epithet in their anti-GM campaigns of the 1990s, though they have since backed away from the word and the hardline stance it represents. But genetically …

The Juxtaposition Of White Racial Identity Development In Teachers And African American Racial Identity Development In Middle School Students, Idonia M. Owens

Education Doctoral

Early adolescence marks the time when African American students begin to develop their racial identity (Phinney & Tarver, 1988; Roberts, Phinney, Masse, Chen, Roberts & Romero, 1999; Tatum, 1997). With school being an important context for this process, it is suggested that a teacher’s racial identity developmental status might play a role in assisting African American students with this progression (Helms, 1990, 1994; Howard, 2006; Tatum, 1997). Missing from the research is an examination of White teacher and African American student interactions through the lens of the racial identity development of both. Using a survey design, this quantitative study focused …

The Efficacy Of Dynamic Written Corrective Feedback For University Matriculated Esl Learners, Norman W. Evans, K. James Hartshorn, Diane Strong-Krause

Faculty Publications

Truscott’s (1996) indictment on error correction in second-language (L2) writing has ignited much discussion and research on the appropriateness of written corrective feedback (WCF) in L2 contexts. Out of this has emerged a body of research that suggests that WCF can positively impact the linguistic accuracy of student writing. However, these studies have examined only one or two error types. A central aspect of the efficacy of any corrective measure has to do with using feedback that is appropriate for the learner and the learning context. This paper builds on previous studies of dynamic WCF, which targets all linguistic errors …

Self-Reported Exercise And Risk Of Osteoporosis In Prostate Cancer Patients Receiving Androgen Deprivation Therapy, Lori J. Mennen-Winchell

Loma Linda University Electronic Theses, Dissertations & Projects

Prostate cancer is stimulated to grow in response to testosterone. Androgen deprivation therapy (ADT) leads to chemical castration and suppression of prostate cancer cell production. Testosterone levels less then 300ng/ml decreases bone mineral density and could result in osteoporosis. Studies have shown that during the first year of ADT, fracture risk, mainly in hips and spine increases about 50%. In men, 40% of hip fractures result in death. Exercise may reduce the risk of osteoporosis and thus contribute to the prevention of hip and other fractures. There is limited data regarding whether exercise is associated with a reduced risk of …

Assessment Of Pain In The Older Adult With Dementia, Helen Laferriere

Theses and Dissertations

Pain is common in the older adult as they continue to age regardless of their cognitive ability. Whether the older adult resides in the community, in a nursing facility or is hospitalized, pain is prevalent in this population. The assessment and management of pain in the older adult with cognitive impairment is a challenge for those in healthcare. Based on the severity of the dementia, the older adult may not be able to verbalize or describe their pain. Therefore, it is vital that healthcare providers are able to identify pain in this population. Observational assessment scales, such as the Abbey …

Replacement Alternatives For Beef Cow Herds: An Analysis Of Retaining Non-Pregnant Cows, Trenton T. Bohling

Department of Agricultural Economics: Dissertations, Theses, and Student Research

A non-pregnant cow is a liability to a producer. Over the last four years, cow-calf producers have had an increased number of non-pregnant cows due to factors like environmental conditions and diseases like trichomoniasis. While most research has indicated that culling a non-pregnant female and replacing the cow with retained heifers, purchased heifers, or purchased cows are the only economic alternatives, recent trends in the cattle market have suggested that keeping a non-pregnant cow may also be an alternative.

Annual beef cow budgets were created based on typical Nebraska Sandhills conditions. Revenues and costs in these budgets vary according to …

Optimal Foraging In Leafcutter Ants (Atta Cephalotes) Selection Of Leaves Based On Proximity To The Nest, May 2011, Robert O. Snowden

Monteverde Institute: Tropical Ecology and Conservation

The foraging tendencies of Atta cephalotes, a leaf-cutting ant, have been widely studied. Optimal foraging theory dictates that ants should maximize rate of energy intake while minimizing costs by harvesting from suitable food sources closer to the nest. However, actual foraging patterns are more disparate and do not always reflect optimal strategies. Here I measure harvesting rates and recruitment speeds at different distances from the nest of A. cephalotes colonies by offering six leaf disk samples every 15 minutes at 5, 10, and 15 meters from the nest entrance. Harvesting rate was significantly higher closer to the nest, with 54% …

Foliage Dwelling Insect Composition In Three Stages Of Forest Regeneration, May 2011, Isa Betancourt

Monteverde Institute: Tropical Ecology and Conservation

The International Tropical Timber Organization (ITTO 2002) estimated that secondary forest make up 60% of all tropical forests. By definition, that means that a majority of tropical forests have gone through succession in the recent past. In the present study I looked at differences between foliage dwelling insects at different stages of succession. A total of eight sweep samples were taken from a regenerating field (RF), a new growth forest (NGF), and an old growth forest (OGF) in San Luis, Puntaranes, Costa Rica to assess the diversity and evenness during the dry season and at an altitude of around 1200 …

Bank Street And Teach For America: Process And Preparation, Paul Shirk

Graduate Student Independent Studies

In this paper I analyze the goals and practices of education that are implied in the mission statements and literature of Bank Street College of Education (Bank Street) and Teach for America (TFA). I noticed and struggled to understand the tension between the mission statements of the two organizations that I was a part of during my master's program. While analyzing the readings and my experiences, I began to see differences between these two organizations' theories and beliefs about child development. I considered how my experiences with children supported or refuted these beliefs. From Bank Street, I recognized many beliefs …

Planning For Building-Integrated Agriculture In Las Vegas, Robert Vralsted

UNLV Theses, Dissertations, Professional Papers, and Capstones

High food prices, concern about food nutrition and safety, and an awareness of commercial farming's environmental impact have generated a renewed interest in sustainable urban agriculture. Advances in controlled environment agriculture (CEA) have made it possible to grow food virtually anywhere in a much more sustainable manner than traditional field-based agriculture. Locating and planning urban farms using retrofitted existing building stock to maximize food production and ease of distribution in Las Vegas requires consideration of multiple barriers related to geography, economics, and the built environment. Consideration of these factors in the planning process informs the design of a successful BIA …

The Effect Of Acute Exercise-Induced Fatigue On Pistol Shooting Performance In Police Officers, Melissa Jean Brown

UNLV Theses, Dissertations, Professional Papers, and Capstones

Duties of police officers include apprehending suspects, which may involve foot pursuit and firing a weapon at a suspect. Previous studies in biathletes and soldiers suggest that shooting performance is compromised when fatigue is present. Purpose: To investigate the effects of exercise-induced fatigue on shooting performance in police officers. Methods: Nine police officers fired five rapid-fire shots at three targets each with a fifteen second rest period in between each trail. Officers then exercised on a cycle ergometer to 85% maximum heart rate or voluntary fatigue. The pretest shooting was repeated post-exercise. Distances of 4 shots from the center of …

Dissertations

The relationship between a mother and her son and its influence on health and risk behaviors as a boy becomes a man has had little exploration. The purpose of this study was to examine the relationships between mother-son connectedness, substance use, serious delinquency, violent delinquency, and criminal justice system involvement in young men. This study uses data from The National Longitudinal Study of Adolescent Health (ADD Health), a school-based study of students in grades 7–12 in the United States. Multiple regression, ANOVA, and logistic regression were used to analyze independent and dependent variables. Results show a perception of connectedness, which …

Pharmacokinetic And Pharmacodynamic Studies Of A Novel Spectinamide Series Of Antituberculosis Agents, V. N. R. Pavan Kumar Vaddady

Theses and Dissertations (ETD)

Spectinamides are novel amide derivatives of the antibiotic spectinomycin that have emerged as a new class of agents to treat tuberculosis. These agents showed potent in vitro activity against Mycobacterium tuberculosis (MTB) compared to spectinomycin and in a preliminary in vivo study in interferon gamma (IFN‑γ) knockout mice, spectinamide Lee1329 reduced the lung bacillary load of TB comparable to streptomycin. We hypothesized that the application of an iterative pharmacokinetics and pharmacodynamics (PK/PD) guided approach would facilitate the optimization of these lead compounds suitable for further development.

A series of in vitro experiments including parallel artificial membrane permeability assay (PAMPA), microsomal …
