The Effect Of Chilling On Diapause And Development Of Washington State Apple Maggot Rhagoletis Pomonella (Walsh) (Diptera: Tephritidae), Nathan J. Lehrman

All Master's Theses

The influence of holding temperatures and chilling periods on diapausing R. pomonella (apple maggot) pupae were the focus of the study. Apples were collected from Pierce and Lewis County in Washington State. After collecting R. pomonella from the fruit, the pupae were chilled at 3°C for 0, 1, 2, 5, 10, 15, 20, 25 or 30 weeks, then allowed to emerge at either 20°C or 26°C. The insects were then monitored for survivorship and eclosion. Rhagoletis pomonella would emerge fastest when held at 26°C and developed on average in fewer degree days (284±252 degree days). However, more adults emerged after …

Women And Evangelical Individualism, Danielle C. Kuehn

All Master's Theses

By comparing the way male ministers presented their faith in gendered terms during the First Great Awakening to the responses of women who embraced their doctrine, the study examines whether women gained autonomy from the evangelical emphasis on individual choice and responsibility. Primary sources were the foundation for the research and included sermons from the most prominent ministers of the era, Jonathan Edwards and George Whitefield. Journals of women evangelicals were invaluable resources providing first hand accounts of the implications of gender roles and religious ideology in evangelicals' lives during and following the Great Awakening. The primary documents studied here …

A Proto-Architecture For Innate Directionally Selective Visual Maps., Sv Adams, Cm Harris

School of Psychology

Self-organizing artificial neural networks are a popular tool for studying visual system development, in particular the cortical feature maps present in real systems that represent properties such as ocular dominance (OD), orientation-selectivity (OR) and direction selectivity (DS). They are also potentially useful in artificial systems, for example robotics, where the ability to extract and learn features from the environment in an unsupervised way is important. In this computational study we explore a DS map that is already latent in a simple artificial network. This latent selectivity arises purely from the cortical architecture without any explicit coding for DS and prior …

Mechanism Of GabaB Receptor-Activated Increases In L-Type Calcium Current In The Neonatal Mammalian Hippocampus, Andrew S. Karls

Dissertations (1934 -)

Activation of the metabotropic GABA_B receptor has most commonly been demonstrated to produce inhibitory effects on neurons, including the attenuation of voltage-dependent calcium current. However, during the early neonatal period in mammalian development, activation of GABA_B receptors leads to an enhancement of calcium current through a specific class of calcium channels, termed L-type channels, (because they conduct Long-lasting current) . This response peaks at 7 days postnatal, and is only demonstrated in a subset of cells. In the work presented here, the signal transduction pathway of GABA_B receptor-mediated increase of L-type current is described.

GABA_B receptors …

Academic Achievement And Perceptions Of Nature Appreciation, Environmental Awareness, And Well-Being Of Participants In Sully's Hill Nature Education Program, Jared Duane Schlenker

Theses and Dissertations

Experiential and hands-on learning are important for any effective educational environment, and when combined with natural elements that can stimulate students' senses to enhance their learning, these educational methods may have a profound effect (Louv, 2008). The Sully's Hill Nature Education Program (SHNEP) allows fifth-grade students at Central Middle School in Devils Lake, North Dakota, to learn in an outdoor setting.

The purpose of this study was to determine if a relationship exists between Devils Lake fifth graders and sixth graders who participate(d) in the Sully's Hill Nature Education Program (SHNEP), and those students who have not participated in the …

The Origins Of An Everyday Behavior: Why Do People Share Meals?, David Lee

Honors Theses

Humans are socially driven creatures that require constant interaction. One way humans have consistently expressed their social nature since prehistory is through sharing meals. Recent studies and literature were examined in order to investigate the roots behind why sharing meals has been the most consistent method of social output. Through careful reading and analysis, reasons behind why people share meals were traced in perspective levels. The biological and molecular aspect explains how humans evolved from prehistoric primates and their similarities associated with food consumption. Genetics and food preferences also play a role by allowing humans to taste food rather than …

The Evangelical Church And Creation Care, J. B. Burt

Honors Theses

The purpose of this research is to determine the extent to which creation care is reaching and influencing the patrons in the pews of Evangelical Christian churches as well as to determine if Evangelicals will ever be prepared to take a strong and widespread stance on the environmental issues of our time. A mixed method research design was employed that consisted of three focus groups that served to directly inform the development of an online survey. Survey respondents consisted of 283 primarily Mississippi residents and students attending colleges and universities in Mississippi. Results illustrated that a majority of Evangelicals do …

Modeling Nitroglycerin-Induced Migraine In Rats, Stephanie Staszko

Honors Theses

The present research sought to determine whether nitroglycerin (NTG) produced changes in clinically relevant endophenotypes of migraine. Rats were given a single injection of NTG or vehicle with the following dependent measures recorded: Rat Grimace Scale, hot and cold tail flick latency, Rotor-Rod performance, and photophobia and movement in traditional and modified light/dark boxes. NTG increased rat grimace scores but did not produce thermal allodynia nor photophobia. Further, NTG produced paradoxical increases in Rotor-Rod performance and movement. These results demonstrate that a single injection of NTG does not produce behaviors that parallel clinical symptoms of migraine.

The Effects Of Adrenergic Antagonists On Spatial Memory In The Zebra Finch (Taeniopygia Guttata), Taylor Williams

Honors Theses

The adrenergic system appears to be involved in the consolidation and reconsolidation of hippocampally dependent spatial memories in mammals. Based on connectivity, cell types, ontogeny and receptor distribution, the avian hippocampus is thought to be a homolog to the mammalian hippocampus. The adrenergic system appears to be fairly conserved but may show some species specializations. To determine if the adrenergic system plays a role in spatial learning and memory in birds, we used a series of experiments to investigate the role of α- and β-adrenergic receptors on spatial navigation and memory in an avian species, zebra finches, using the Day …

An Evaluation Of Soil Extracellular Enzyme Activity In Response To Burning As A Forest Restoration Technique, William M. Steward

Honors Theses

Burning is a method of forest restoration with the goal of returning natural tree species to ecosystems. Burning has a wide range of effects on an ecosystem, including the alteration of important soil processes and characteristics. One of the key components of soil is the activity of extracellular enzymes, which can be used to provide insight into the nutritional requirements of soil microbes as well as nutrient availability and cycling. Because enzymes are important in the overall functioning of soil and can be used to assess soil health, there is great need to examine the effects of burning on soil …

Effects Of Novel Feed Ingredients And Additives On Feed Quality And Broiler Performance, Ashley Marie Evans

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the poultry industry, feed and feed manufacture account for 60 to 70% of production costs. Because of this, integrators are continually seeking ways to decrease costs while maintaining pellet quality and bird performance. The research presented in this dissertation offer several novel feed ingredients that have the potential to replace costly feed ingredients, increase pellet quality, improve bird growth and performance, and improve nutrient digestibility. In Chapter 2, four experimental phytase enzymes (A -- D) were examined for thermostability during pelleting, as well as efficacy in vivo. Phytase activity post-pelleting demonstrated high variability between phytases, ranging from 120 to …

Evaluating The Inclusion Of Phytase Super-Dose In Various Broiler Diet Formulations And Novel Pellet Binders, John W. Boney

Graduate Theses, Dissertations, and Problem Reports (ETD)

Grains commonly used in poultry diets contain phytic acid, a known anti-nutrient that binds dietary phosphorus rendering it unavailable for absorption also decreasing the digestibility of other nutrients. Phytic acid also increases mucin production and endogenous amino acid secretions causing a gut irritant effect which may decrease performance. An abundance of phytase literatures suggests that phytase enzymes can liberate bound phosphorus enhancing phytate phosphorus utilization and bone mineralization. Recently, the use of super-doses of phytase has been suggested to, not only liberate bound phosphorus, but to alleviate the gut irritant effect associated with phytate phosphorus. Therefore, an experiment was conducted …

Boredom And Memory For Positively And Negatively Valenced Words, James Kirchner

Honors Theses

The purpose of the present study was to determine whether boredom affected memory for positively and negatively valenced words in addition to class names (e.g., History) that were presented in an auditory modality while participants listened to a recorded script. This was accomplished by comparing the recall of a doodling group, who were asked to shade in shapes while listening to a recorded script, with a non-doodling group, who simply listened to the script. The results indicated that participants in the non-doodling group recalled more class names (e.g. History) from the script than participants in the doodling group. In addition, …

Cognitive Poetics And Italian Literary Criticism, John Biffle

Honors Theses

This thesis explores the possibility of the application of cognitive poetics to Italian literature, with a comparison to four major nineteenth century currents of literary criticism. Given the interdisciplinary nature of the research, the data was obtained from reviewed psychology articles, textbooks regarding both psychological and literary subjects, original sources containing the examined poetry and prose, e-books, and open source web material for literary works that lacked copyright. Unless specified, all translations from Italian to English were done by me. Since cognitive poetics are based on the assumption that we perceive literature similarly to how we perceive reality and that …

Promotion Of Environmental Engagement Through Positive Youth Development In Tanzania, Katherine Westfall

Honors Theses

With climate change and environmental degradation already having devastating effects on communities in sub-Saharan Africa, enhancing youth's commitment to the environment and mobilizing their pro-environmental action is increasingly urgent. In this study, we explored predictors of environmental commitment and action based on a model of positive youth development. We predicted that sociodemographics, self-efficacy, connection to nature, sense of community, and club participation would predict environmental commitment and action. Tanzanian youth (N = 959) from regions across the country completed self-report measures assessing these constructs. Using a series of logistic and hierarchical multiple regressions, we were able to predict statistically significant …

Choice Between Reinforcers With And Without Delayed Shock, Aaron D. Dumas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Some problematic human behaviors can be conceptualized as choice of a large immediate reinforcer followed by a delayed aversive event, in lieu of a small immediate reinforcer and no delayed aversive event. For example, a night of binge drinking may result in ample social reinforcers and other fun in the short-term, but it is followed the next day by an intense hangover. Alternatively, opting for moderate alcohol consumption might not produce as intensely pleasing of an evening, but it avoids the aversive hangover. The aim of the present experiment was to develop an animal laboratory model for studying such choice …

An Investigation Of The Effects Of Hysteresis On The Rotation Percept, Maximilian James Shumake

Honors Theses

Although much research has been done on the role of hysteresis in apparent motion displays, no research has investigated the effects of hysteresis for rotary motion. The present experiment sought to determine and quantify the effects of hysteresis on the rotation percept. Participants viewed two types of apparent motion stimuli, which consisted of tokens appearing to move in a clockwise, counterclockwise, or chaotic fashion. One of the displays slowly changed from favoring a percept of rotation to a percept of non-rotation and vice versa. We fit the data using a logistic function and compared the point at which the direction …

The Effect Of Sumatriptan On Clinically Relevant Behavioral Endpoints In A Recurrent Nitroglycerin Migraine Model In Rats, Morgan Elizabeth Davis

Honors Theses

The present research sought to determine the effects of sumatriptan on clinically relevant behavioral endpoints in migraine produced by repeated nitroglycerin (NTG) administrations in rats. Rats were given 5 NTG administrations each of which was followed by either saline, 0.3 mg/kg sumatriptan, or 1.0 mg/kg sumatriptan over a 2-week period. During their 5th NTG migraine episode, behavioral endpoints were the Rat Grimace Scale, photophobia, and movement. Sumatriptan dose dependently attenuated a) loss in weight, b) elevated Rat Grimace Scale pain scores, and c) decreased movement in the modified light-dark box. In addition, rats with the highest dose of sumatriptan tended …

Down Creek A Screenplay, Elizabeth Britt Mcclure

Honors Theses

Growing up, the story was told to me this way: one day, a little boy’s foot washed up on a beach in Charleston. An investigation found that the foot belonged to a patient of Dr. Reed, an orthopedic surgeon who had removed the boy’s foot some three years prior. The doctor had stored the boy’s foot in his freezer at home. When one day the freezer broke down. Dr. Reed disposed of the body part by substituting it for raw chicken in his crab trap. Somehow the foot escaped the bait compartmentmuch to the leathery beachgoers’ horror. Even as a …

Inhibition Of Arterial Kdr Channels By Dpo-1 And Activation Of Cloned Human Bk Channels By Bpa-Ms, Ibra S. Fancher Iv

Graduate Theses, Dissertations, and Problem Reports (ETD)

The following documents our attempt at answering a fundamental question in vascular smooth muscle: Which K+ channels control membrane potential, and thus, vascular tone? A number of groups have approached this question and great strides have been made; however, uncertainty remains as to which specific K+ channel(s) underlies this physiologically important current. Previous studies using nonselective pharmacological inhibitors of voltage-dependent K+ (KV) channels, particularly delayed rectifier K+ (KDR) channels, indicate membrane depolarization, Ca2+ influx, and vasoconstriction. Importantly, however, there are more than 40 genes known to encode KV channel subunits. We hypothesize that KDR channels composed of KV 1 subunits …

A Strategy To Share The Gospel With The Hindu Community In The South Kenya Conference, Willys M. Oruta

Doctor of Ministry Projects

Problem

The Adventist Church in the South Kenya Conference has not developed a strategy to share the Gospel with the Hindu community. The Hindu community is generally looked at as an idol worshipping group. However, this community conducts most of the business in many towns in Kenya. For this reason, they should not be neglected because God wants them to be part of His kingdom. Jesus died for the salvation of the whole world; therefore, a strategy to share the Gospel with the Hindu community is a divine command. In the South Kenya Conference, particularly in Kisii, the Hindu community …

Using A Small Group Approach To Increase Church Growth In The Gikondo Seventh-Day Adventist Church, Schadrack Nsengimana

Doctor of Ministry Projects

Problem.

Although many people are baptized at the Gikondo Seventh-day Adventist Church each year, about 70% leave the church shortly after baptism.

Method.

The biblical principles of church growth were studied and theological reflection focused on four biblical themes. First, the call to integrate the Great Commission into the daily life and relationships of the individual believer in Christ was examined. Second, church growth as faithfulness to God was explored as a biblical teaching. Third, the view that a healthy church embraces multiplication of disciples as its core responsibility was studied from a biblical perspective. Fourth, the role of the …

A Strategy To Increase Giving In The South Kenya Conference, Julius M. Bichang'a

Doctor of Ministry Projects

Problem

The South Kenya Conference (SKC) was the first to gain conference status in Kenya in 1981. Unfortunately it continues to struggle financially to the point of receiving subsidies from other conferences for its day-to-day operations. The annual stewardship statistical reports for the last 10 years show that the tithe is slightly higher than the offerings. While 14 % of the members return their tithes; only 8 % of them give offerings. This was one of the challenges I was faced with when I was elected as the conference Stewardship Director. This indicates that there is a weak commitment to …

New Member Retention Strategy For The Makoko Church, Yoseph Nyambega Otieno

Doctor of Ministry Projects

Problem

The effort made by the Makoko Seventh-day Adventist Church to fulfill the great commission (Matt 28:19-20; Mark 16:15-16) through public evangelism is challenged by the constant exodus of newly baptized converts out of the church. The emigration of new members out of the church has a compound effect on the church; it denies the church the opportunity to disciple new converts and discourages church members from continuing to fund public evangelisms as they are considered a waste of resources. When people accept Jesus they also receive eternal life, but when they leave the church they risk forfeiting the gift …

A Biblical Hiv/Aids Mitigation Strategy In The Oyugis Central Adventist Church, Kenya, Tom Eli Arunga Ogal

Doctor of Ministry Projects

Problem

HIV/AIDS is an epidemic that has and continues to adversely impact the quality of life of not only the members of the Oyugis Central Seventh-day Adventist Church, but of the community in general. Its negative impact touches the social, economic, political, and demographic fabric of society. It is robbing the Adventist Church and society in general of requisite human resource through death and sickness, and is adversely challenging the church’s competencies to effectively engage in its mission.

Method

The Logical Framework Approach (LFA) was used to present the strategy. A Gantt chart was also be used to detail the …

Resisting The Influence Of The Imeyomwana Heresy In The Nyangweta District, Lenard B. Aencha

Doctor of Ministry Projects

Problem

Imeyomwana (a heresy involving the concept of what it means to be in Christ), a group of former Adventists, is causing problems in the Seventh-day Adventist Church in the Nyangweta district of the South Kenya Conference. Many of their teachings contradict those of the Seventh-day Adventists Church and many members are apostatizing to this group.

Method

To deal with the heresy I employed a two-pronged strategy. On one hand I sought to enter a dialogue with those involved in Imeyomwana, while on the other hand I confronted the false teaching with biblical truth. This strategy employed two powerful planning …

Health And Social Ministries: A Holistic Approach To Ministering In Contemporary Society, Ezekiel Adeyemi Oyinloye

Doctor of Ministry Projects

Problem

It has been observed for thirty years that Adventists conventional way of doing outreach ministries especially in the cities, fail to have expected response that fulfills goals. Attitudes of people are apathetic and reserved they stand aloof and are removed from sharing in what has been offered. They cannot be bothered. The inner city of Ibadan especially displays this type of attitude. Thus, inner city Ibadan has remained unentered by the Adventists since the inception of the Church in Ibadan a century ago. There is no single church of the Seventh-day Adventists in inner city Ibadan.

Method

A strategy …
