Motherhood, Memory And Aging : Object Recognition Performance, Julia Margaret Friedenberg

Master's Theses

Reproductively experienced female rats have been shown to have attenuated stress responses, improved visual systems, and better memory and learning. This study sought to extend those findings by comparing aged reproductively experienced and aged virgin female rats on an object recognition task, as well as comparing levels of corticosterone and 17p-estradiol and neural activation. Multiparous (MP, 2 reproductive experiences) females performed better on the task and demonstrated quicker habituation to the task than nulliparous (NP, no reproductive experiences) females. No hormonal or neural activation differences were found. The present study contributes to the growing research areas of reproductive experience and …

Automatic Spatial Processing Of Threatening And Positive Information In Participants With High And Low Levels Of Trait Anxiety, Ryan W. Hansen

Master's Theses

The study sought to investigate potential differences in automatic spatial processing of threatening and positive information in anxious and non-anxious individuals. Participants evaluated threatening and positive words and pictures in a memory task in which the stimuli's varying spatial position was incidental to the task. Participants demonstrated increased accuracy with threatening stimuli, and a decreased accuracy when the word location varied between initial presentation and test. The results did not provide evidence that threatening stimuli were associated with an increased degree of spatial processing, or that this relationship would be influenced by trait anxiety.

Intricacies Of Development : The Impact Of Maternal Experience And Isolation On The Social Development Of Juvenile Male Rats, Lillian Maria Christon

Master's Theses

Reproductive experience induces changes in females. Parity-related differences in maternal treatment of offspring can induce enduring changes in offspring. The relationships between maternal experience, early social isolation, and development were explored in rodents in this experiment. Male rats were weaned from multiparous (MP) and primiparous (PP) mothers and placed into isolation or social housing for four weeks. They were then observed in a social-interaction test. Social behavior and neural oxytocin and vasopressin were assessed post-testing, while corticosterone levels were measured across the four weeks. Weaning was extremely stressful for all offspring. PP- and MP-raised pups exhibited differences in social behavior, …

Early Vocabulary Development In English, Mandarin, And Cantonese : A Cross-Linguistic Study Based On Childes, Shuxia Liu

Master's Theses

Early language development is an exciting topic in the field of child language acquisition. Only a limited amount of cross-linguistic studies has attempted to investigate the similarities and differences in child language development across different languages. In this thesis, I present a study based on English, Mandarin and Cantonese corpora extracted from the Child Language Data Exchange System (CHILDES, MacWhinney, 2000). I investigated the lexical compositions of certain lexical categories (nouns, verbs, and adjectives) in children and their caregivers’ vocabularies across eight different children age groups ranging from 13 to 60 months. ANOVA, frequency analysis, and cluster analysis were used …

Universal Disaster Impact Scale, Brian James Evans

Master's Theses

When disasters occur affecting multiple communities differently, can a determination be made as to which community is in need of financial or humanitarian aid the most? This study proposes a universal disaster impact scale that will allow the impacts of a large variety of disasters, including natural and human systems failures, to be measured against one another. The Universal Disaster Impact Scale includes both quantitative and qualitative disaster impact measurements combined with an economic factor for the affected country in an equation which provides a numeric rating for the disaster. The rating is used to measure the level of need …

The Next Generation Of Emergency Management : Proposal For A New Model Of Emergency Operations Center For A Growing Regional Emergency Management System, John D. Eggleston

Master's Theses

The emergency operations center organizational model used by the Charlottesville/Albemarle/University of Virginia (CAUVA) Emergency Management Agency is organized around the various departments that staff the center. The EOC model has been used to coordinate small scale natural disasters and training exercises, but has never been used to coordinate a significant actual event. After-action reports of previous events and exercises have highlighted several functional deficiencies and have led some local and state officials to doubt the model's ability to coordinate a significant event... The research process involved a literature and extant document review which discovered that there were four recognized EOC …

A Study Of The Best Spanish Training Practices For Police Officers, Nicole Marie Otero

Master's Theses

Within the last ten years, the Hispanic population in the United States has grown immensely. This presents a communication problem between the Hispanic communities and the police departments who protect and serve them. This also creates a serious liability issue for police departments. Currently, law enforcement is struggling to adequately train police officers how to speak Spanish. This research examines ways for Chesterfield and Henrico County Police Departments to develop the Spanish-speaking skills of their current police officers. This research further provides details of possible costs to provide adequate Spanish-speaking training to the police officers in both counties. The data …

The survey focuses on preventive and intervention programs and their effectiveness, sociological and economical factors leading to imprisonment, and statistics supporting incarceration growth. The research goal is to validate program contents and components factoring into imprisonment. The study of others and information generated through this study are used to determine program needs and current effectiveness. This study explores reasons offenders frequent the …

Generational Competence And Retention : A Study Of Different Generations In Law Enforcement And How These Differences Impact Retention In The Chesterfield County Police Department, Gary Scott Edwards

Master's Theses

There are currently four distinct generations in today's workforce (Veterans, Baby Boomers, Generation X, and Millennials). This presents unique challenges for employers since each of these generations is affected and shaped by different events in their lives, which define the values they bring to work. These differences can be increasingly difficult to manage and may lead to conflicts. Significant research has been conducted in this area, but little has focused on public sector employees, specifically sworn law enforcement officers. This research examines whether generational differences observed in society as a whole are the same as those differences found in law …

Shrines And Prayers: Two Missing Elements Of Comprehensive Mass Fatality, Rhonda Keyes Pleasants

Master's Theses

As a Licensed Funeral Service Provider, I am aware of the special issues which surround mass fatalities. A study of numerous mass fatality plans yielded identification of two missing elements from most plans which are critical to mass fatality management. The first missing element is ritual used in the respectful treatment of the dead. The second missing element is religious precepts regarding caring for and final disposition of the dead based upon the particular belief system of the deceased, their family, surrounding community, and culture. Specific qualitative methods of research used were a review of the professional literature, identification of …

A Role For Vasopressin And Oxytocin In Parental Behavior Of The Male Sprague-Dawley Rat, Ekaterina V. Karelina

Master's Theses

Paternal behavior, though infrequent in many mammalian species, can be induced under laboratory conditions through manipulation of either hormonal or environmental states. Rodent studies of parental behavior have implicated similarities for males and females in not only the actual behavioral repertoire, but also the brain mechanisms governing the set of behaviors in both sexes. The current project investigated changes in oxytocin and vasopressin in the hypothalamus of paternal male rats. We found that paternal behavior, which was readily induced through sensitization (chronic pup exposure), was significantly correlated with increasing oxytocin and vasopressin immunoreactivity within the paraventricular nucleus. Further, corticosterone levels …

Learned Fear And Reaction To Novel Stimuli: Behavioral And Hormonal Stress Responses In The Maternal Rat, Brandi Nicole Rima

Master's Theses

The present thesis examines the relationship between reproductive experience and the behavioral, neural, and hormonal processes of learned fear in the female rat. Multiple research models indicate that reproductive experience functions to decrease the female's stress response in potentially harmful environments, thus providing her with numerous survival benefits, including decreased fearfulness, increased aggression, and refined hunting skills. Based on existing understandings of maternal experience and unconditioned fear, this study was designed to determine how nulliparous (no reproductive experience, NP), primiparous (one reproductive experience, PP) and multiparous (more than one reproductive experience, MP) rats comparatively respond to a Pavlovian paradigm of …

Conditional Love : A Study Of Situational Differences In Rooting For An Underdog, Sheila Margaret Hindle

Master's Theses

While people tend to root unabashedly for underdogs in the domain of athletics, underdogs do not generally receive the same tremendous support in matters of business. This may occur for a variety of reasons, but of particular interest is the fact that an individual's perception of a situation as both self-relevant and of high consequences may prove detrimental to his or her willingness to support an underdog. Two studies were conducted to explore these hypotheses. Study 1 (N=48) required participants to read a brief scenario depicting a situation of varied self-relevance and consequences, and then select a company to complete …

Predictors Of Breast And Cervical Cancer Screening Among Vietnamese Immigrant Women, Anh B. Nguyen

Master's Theses

Predictors of breast and cervical cancer screening among Vietnamese immigrant women. Anh B. Nguyen, Master of Arts in Psychology, University of Richmond, 2006. Thesis director: Barbara K. Sholley, Ph.D Although practicing preventative healthcare is an important part of a healthy lifestyle, some high-risk populations do not engage in preventative screenings for cancer. Vietnamese American women constitute a high-risk group in gynecological cancers, and it was hypothesized that tenure, acculturation, health insurance, a regular source of care, education, employment status, and marital status would affect rates of cancer screening. It was also hypothesized that the Vietnamese population would have different trends …

From The Pixels Up : Processes And Procedures In The Construction Of A Neural-Site Geographic Information System, Christopher John Mason

Master's Theses

This study examines the question, is it possible to develop a neutral-site Geographic Information System (GIS) that addresses information needs useful for the training of emergency management personnel? To answer this question a subordinate question requiring an answer is what specific steps are required to accomplish this goal? As a base for the data provided here, the history of cities as an initial root of civilization and the concept of emergency management are discussed. Direct intersections, where the specific applications of emergency management technology provide real benefits to local governmental organizations, such as those at the city level are also …

Eliciting Facial Expressions In Children With And Without Down Syndrome, Orietta Coz

Master's Theses

This study investigated facial expressions of children between the ages of 10 and 15 years with Down Syndrome (experimental group) and compared them to typically developing children (control group). Elicitation of facial expressions was carried out through showings of video clips. Trained observers were used to code expressions of happiness, anger, and disgust from video recordings that were made of the children’s reactions while they watched the video clips.

I hypothesized that Down Syndrome children will not differ from typically developing children in the frequency of elicited happy expressions. However, I expected them to differ in the frequency of elicited …

Self-Esteem And The Underdog : Why Stability Of Self-Esteem Matters In Social Situations, Kelly Dyjak

Master's Theses

Differences related to self-esteem and their possible influences on perceptions of underdogs were investigated. Global self-esteem and stability of self-esteem were evaluated using The Rosenberg Self-Esteem Scale. Participants' self-esteem was threatened by using the false feedback technique. Finally, perceptions of a competition between an underdog and a top dog were evaluated. The results demonstrated that although participants with stable and unstable self-esteem favor the underdog, participants with unstable self-esteem favor the underdog even more than the participants with stable self-esteem. The findings reinforce the robustness of the underdog effect and highlight a consequence of having unstable self-esteem.

A Cognitive Intervention To Increase The Salience Of Intrinsic Thoughts Associated With Exercise, Katie S. Moran

Master's Theses

A four-week cognitive intervention was created to increase the salience of intrinsic thoughts associated with exercise in moderately extrinsic exercisers. Participants were assigned to either an intervention or control condition. Those in the intervention condition were asked to respond to questions concerning the pleasure, enjoyment and/or satisfaction experienced during or after their exercise regimen each week. Results showed a marginally significant two-way interaction (p = .059) between the control and intervention condition over time. Those in the intervention condition showed a greater increase in intrinsic motivation than those in the control condition. These results. while only marginally significant, were in …

Sentence Recognition In Native And Foreign Languages : Comprehension Of Form And Meaning, Sara Elizabeth Sepanski

Master's Theses

The goal of language comprehension is to retrieve and retain the meaning of speech or text. Research with monolinguals has shown that participants' ability to detect structural changes in sentences decreases with time, while their ability to detect meaning changes remains accurate (Sachs, I967). In this study I examined whether this monolingual pattern holds for bilingual speakers in a second language. English-Spanish bilinguals at three different proficiency levels participated in a reading task in which native (LI) and non-native (L2) language sentences were presented. Participants read both LI and L2 sentences and were then tested for their recognition of the …

Affective Benefits Of Capitalizing On Personal Positive Events, Daniel B. Goldman

Master's Theses

The present study examined how disclosing personal positive events influenced ensuing positive affect (PA). Forty undergraduate students reported personal positive events either privately or to a friend. All participants made written and vocal disclosures, counterbalanced to control for order effects. We hypothesized that participants who vocally reported positive experiences to a friend would have the highest PA scores subsequent to disclosure. Results from a two-way mixed ANOV A failed to support the hypothesis. Trait optimism was significantly related to positive affect, but its inclusion as a covariate in the ANOV A did not influence the pattern of results. These results …

The Life-Long Diminution Of Anxiety Response As A Consequence Of Reproductive Experience, Ilan M. Mcnamara

Master's Theses

Reproductive experience (RE), associated with hormonal fluctuations and enriching environmental stimuli, enhances spatial memory and blunts responses to stress/anxiety. Whereas stress reductions occur during lactation, the persistence of the RE-anxiolytic effects is unclear; and little research has focused on the HP A axis, amygdala, and other anxietyrelated areas. Using an elevated plus maze (EPM), we examined anxiety in nulliparous (NP), primiparous (PP), and multiparous (MP) females (zero, one, or two litters, respectively) at 6, 10, 14, 18, and 22 months of age. Brains were subsequently analyzed for neurodegeneration in dorsal raphe nucleus (DRN). RE significantly dampened anxiety (defined by time …

The Relationship Between Age And Depression : A Self-Efficacy Model, Brandyn M. Street

Master's Theses

From an applied perspective, it is useful for clinicians and researchers to know what variables are more likely to be related to depressive symptoms for some groups than for others. From the social-cognitive perspective, symptoms of depression are linked to people's beliefs that they are unable to regulate or control their own functioning. The purpose of the present study was to test social cognitive theory and its claims about self efficacy by examining whether age and sex differences in depression are a function of emotion regulation, emotional self-efficacy and response styles to depression. The results indicated that females had a …

"Paper Sack Brown" : Effects Of Age, Skin Tone, And Stereotype Threat On Cognitive Performance And Self-Efficacy Among African Americans, Breonte Stephan Guy

Master's Theses

Divergent African American skin tones have led to negative stereotypes and outcomes regarding darker-skinned African Americans in many domains, including educational and occupational (Hill, 2002). This study assessed the effects of skin tone and stereotype threat (Steele and Aronson, 1995; Steele, 1997) on cognition in younger and older African Americans. A 2(Skin Tone: light, dark) X 2(Age: young, old) X 2(Stereotype Threat: Threat, Non-Threat) between subjects design was used. Seventy-four African American adults ranging in age from 18 to 86 years completed a battery of cognitive measures. Darker-skinned adults performed more poorly on three tests of intelligence, a paired-associates memory …

The Presence Of Pups After Birth : Effects On Spatial Memory And The Pre-Synaptic Protein Synaptophysin, Abbe Hoffman Macbeth

Master's Theses

A newly maternal rat goes through many changes when she gives birth, mostly due to prolonged elevation of hormones, particularly estrogen. Estrogen has been shown to increase memory capabilities by increasing synaptic activity in the CA1 hippocampus, but exactly how is still unknown. The current project uses reproductive experience to determine whether high hormone levels experienced during pregnancy and lactation affect spatial memory and synaptophysin, a pre-synaptic protein that controls vesicle exocytosis and thus may be responsible for enhanced synaptic connectivity. We found that reproduction itself does not affect memory of a spatial task, but the presence of pups has …

Brain-Derived Neurotrophic Factor And Maternal Behavior : Neuronal Alterations In The Medial Preoptic Area And Suppression Of Pup Attacks, Lillian Flores Stevens

Master's Theses

Brain-derived neurotrophic factor (BDNF), by virtue of its relationship to various neurotransmitter systems, hormones, and to estrogen in particular, may play a role in maternal behavior. To explore this possible role, female virgin Sprague Dawley rats received continuous intracerebroventricular infusions ofBDNF sense oligonucleotide and were exposed to pups for maternal behavior testing. Behaviorally, BDNF sense had no effect on maternal behavior but did significantly suppress pup attacks during the first 24 hours of exposure. BDNF had a significant effect on neuronal morphology in the medial preoptic area (mPOA) as well, such that neurons in this region exposed to BDNF had …

Adviser Awareness Of The Kansas Student Publication Act (1992), Latisha D. Haag

Master's Theses

This thesis was a descriptive study examining adviser awareness of the Kansas Student Publication Act (1992) as reported by advisers who were members of the Kansas Scholastic Press Association during the academic year 2002-2003. Because there were no studies prior to the passing of the Act, there was no base line study to determine whether the Act has had an impact since its passing. For this study, 216 advisors, the complete membership of the Kansas Scholastic Press Association, were either given a cover letter explaining the questionnaire and questionnaire at one of the fall conferences, or mailed a cover letter …

Reproductive Experience And Aging : Possible Neuroprotective Effects Of Motherhood, Jessica Dawn Gatewood

Master's Theses

Hormonal fluctuations associated with pregnancy and post partum periods create significant changes in the brain and behavior in female rats. Animals were tested in a land version of the Morris Water maze for three days at 6, 12, 18 and 24 months. At the ages of 12, 18, and 24 months animals were also tested in the same maze using a reversal task. At the conclusion of the study brains were analyzed for Amyloid Precursor Protein (APP) to determine the amount of neurodegeneration among the groups. Multiparous animals showed significantly superior performance , followed by primiparous animals, and nulliparous animals …

The Effects Of Childhood Social Competence On Young Adults Interpersonal Competence In Dyadic And Family Relations: An Exploratory Analysis, Gwen Renae Pursell

Master's Theses

The majority of peer relations research focuses on the short and long term effects of childhood peer rejection and aggression for development. The importance of social competence and more specifically, its long term effects on development have not been as thoroughly examined within the peer research. In this 20 year follow-up investigation, preadolescent social competence, peer rejection, and aggression scores were used to predict adult measures of dyadic adjustment, family environment, and family expressiveness. In addition, both preadolescent peer relation scores and concurrent adult dyadic and family scores were used to predict offspring emotion regulation abilities, internalizing and externalizing symptomatology, …
