Transcriptional Regulation Of The Porcine Type Ii Gnrh Receptor Gene, Vanessa M. Brauer

Department of Animal Science: Dissertations, Theses, and Student Research

The classical mammalian form of gonadotropin releasing hormone (GnRH), GnRH I, is a hypothalamic neuropeptide that functions as a key regulator of reproduction. The interaction between GnRH I and its receptor, GnRH receptor I (GnRHR I), stimulates gonadotropin secretion from the anterior pituitary gland. The gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH), act on the gonads to stimulate either steroidogenesis and ovulation or gametogenesis, respectively. The steroid hormones produced in the gonads act through a feedback pathway to regulate the production of both GnRH I from the hypothalamus and gonadotropins from the anterior pituitary.

Another form of GnRH, …

A Rat Model Examining Behavioral And Neurochemical Effects Of Passive Exposure To Aggression On Observers, Hideo Suzuki

Dissertations

Previous studies have consistently reported that passive exposure to aggression is a risk of aggressive inclinations for a human witness. However, it is unclear whether a witness' aggressiveness is semi-permanently socialized or temporarily primed. Furthermore, a neurochemical mechanism of passive exposure to aggression also remains unaddressed in clinical literature. The present research used a rat model to clarify the behavioral and neurochemical effects of passive exposure to aggression. First, rats were screened for their aggressiveness after they were acutely or chronically exposed to aggression or non-aggression. It was found that observer rats chronically exposed to aggression exhibited more aggression than …

The Importance Of Comprehensive Clinical Social Work Assessments For Determination Of Older Adult Guardianship Petitions In Cook County Probate Court, Chicago, Illinois, Heather Jones

Dissertations

As our population ages there seems to be a strong current toward seeking surrogate decision-makers for individuals, who appear unable to manage their lives and make clear choices. Guardianship is the most profound course of action when determining that an older adult lacks decisional capacity. Older adults make up the majority of persons adjudicated incapacitated and, in turn, are assigned guardians (Crampton, 2004; Teaster, Schmidt, and Roberto, 2004). There is limited research about older adult guardianship, so this study is opportune because of the increased longevity of the population, with the most rapid growth among the very old, who likely …

Eutrophication And The Macroscope, Scott W. Nixon

Graduate School of Oceanography Faculty Publications

It is important to view eutrophication as an increase in the supply of organic matter to an ecosystem rather than as a simple problem of nutrient pollution. This emphasizes that eutrophication is a fundamental change in the energetic base that may propagate through the system in various ways and produce a variety of changes. Some of these changes may be desirable (e.g., increased secondary production) and some may not (e.g., hypoxia). Defining eutrophication in terms of changing nutrient concentrations or chlorophyll levels or species composition confuses symptoms with the underlying phenomenon. While nutrient enrichment is the most common cause of …

Apple pomace is an important co-product from the cider industry in the UK and was ideally suited for this purpose. The minimum of total sugars necessary for a successful fermentation was found …

Nitrogen Dynamics In Integrated Agricultural Systems In Central Mexico, Joel Velasco Velasco

Other Faculty of Science and Engineering Theses

Smallholdings (<5 ha) represent 73% of the total agricultural production systems in Mexico. Many are of low productivity, and little quantitative data has been published on the impact of traditional nitrogen (N) management practices on environmental performance at farm scale. Nitrogen is the most important nutrient for increasing crop yields. While the benefits from the use of N fertilizer are self evident, it has resulted in low efficiency of N utilization and environmental problems. This project aimed to assess N dynamics in Integrated Agricultural Systems (lASs) in central Mexico. Nitrogen inputs, outputs and internal transfers were assessed and the impact of selected management practices on nitrogen flow, productivity and environmental performance were analyzed using nitrogen use efficiency (NUE) indices. A predictive framework tool was developed following whole farm methodologies to quantify N flow, and to assess selected (NUE) indices such as 0/1 ratio, N loss, accumulated N, and the change of N in the soil pool at farm scale. Data used for the development of the predictive framework was derived from experimental evaluations of ammonia emissions during vermicomposting, and integrated with data from the literature, together with data from an integrated agricultural systems prototype in Montecillo Mexico. The main N inputs into integrated agricultural systems in the Texcoco region were estimated to be in the following order of significance: biological N fixation (11 - 532), manure (15 - 225), fertilizer (0 - 140) and rainfall water (30 - 35 kg haˉ¹ aˉ¹). The main N outputs were: N losses (70 - 528 kg haˉ¹ aˉ¹) and exported N in marketable products (72 - 338 kg haˉ¹ aˉ¹). Experimentally derived estimates of ammonia emissions during vermicomposting of sheep manure ranged from 10 - 15 kg Mgˉ¹ DM which corresponded to 42 - 47% of the initial N content in the manure substrate. The impact of current management practices showed 0/1 ratios ranging from 0.30 - 0. 76, N losses ranged from 76 to 210 kg haˉ¹ aˉ¹ and N depletion/ accumulation ranged from -25 - 143 kg haˉ¹ aˉ¹. The effect of selected management practices on 0/1 ratio was as follows: crop sequence > stocking density > livestock type > manure management. Whereas for N loss it was stocking density > livestock type > manure management > crop sequence. Higher productivity together with a more benign environmental impact could be attained in smallholder by implementing simple recommended manure management practices at farm scale.

An Analysis Of The Effectiveness Of Functional Behavioral Assessment For Students With Emotional Behavioral Disabilities, Megan Kale Brose

Dissertations and Theses @ UNI

Functional behavioral assessment (FBA) is defined as "a set of assessment procedures used to identify variables that promote and maintain challenging behavior and based upon this assessment, interventions are selected that alter one or more of these variables" (Stichter & Conroy, 2005, pp. 19-20). FBA has received a great deal of attention since the passage of the Individuals with Disabilities Education Act (IDEA)l997 amendments, which require the use of FBA for all special education students upon referral of alternative educational placements due to behavior resulting in disciplinary action. There has also been considerable questioning of and need for research in …

Family Involvement Strategies At The Meskwaki Settlement School, Carol Gary Meyer

Graduate Research Papers

When parents become involved in the education of their child research shows positive results for parents and children. However, not all parents know how to be meaningfully involved, and those that are involved may not understand all that is happening in their child's education.

At the Meskwaki Settlement School being meaningfully involved is an important issue to parents. There is a past history of fear of education due to forced removal to boarding schools far from families and cultural ties. There is a need for parents to connect not only with their child in the school but also with the …

Consumer Decision Making And Aging: Current Knowledge And Future Directions, Carolyn Yoon, Catherine A. Cole, Michelle P. Lee

Research Collection Lee Kong Chian School Of Business

We review existing knowledge about older consumers and decision making. We develop a conceptual framework that incorporates the notion of fit between individual characteristics, task demands and the contextual environment. When the fit is high, older consumers use their considerable knowledge and experience to compensate for the impact of any age-related changes in abilities and resources. When the fit is relatively low, older consumers feel increased need to adapt their decision making processes. We discuss these consumer adaptations and propose a number of research questions related to the processes underlying them in order to contribute to a better understanding of …

Bound By Injustice: Challenging The Use Of Shackles On Incarcerated Pregnant Women, Dana Sussman

Cardozo Journal of Equal Rights & Social Justice

The use of shackles to restrain a pregnant woman during the birthing process is a barbaric practice that needlessly inflicts excruciating pain and humiliation. It is widely condemned by members of the international community, including leading medical and public health associations. Although human rights advocates have effected significant policy change in the past ten years to eliminate the use of shackles on women in labor, it remains routine practice in many American prisons and jails. Reproductive rights advocates should consider this a reproductive justice issue and build on the gains of the human rights community to bring legal claims challenging …

Evaluation Of Glyphosate-Tolerant And Conventional Alfalfa Weed Control Systems During The First Year Of Establishment, Robert Wilson Jr., Paul Burgener

Department of Agronomy and Horticulture: Faculty Publications

A field trial was conducted for 3 yr (2005 through 2007) near Scottsbluff, NE, to examine weed control, crop safety, forage production, and economics of glyphosate-tolerant and conventional alfalfa establishment systems. Glyphosate applied to alfalfa at the unifoliate growth stage provided 67% weed control and was similar to imazamox applied at the two-trifoliate leaf stage. Delaying glyphosate application until alfalfa had reached the two-trifoliate growth stage improved weed control to 83%, and weed control was similar to imazamox plus 2,4-DB and imazethapyr plus 2,4-DB. Imazamox and imazethapyr caused minor crop injury, and the addition of bromoxynil or 2,4-DB to both …
