The Acute Hormonal Response to the Kettlebell Swing Exercise

Description: The purpose of this investigation was to examine the acute hormonal response to a bout of kettlebell swing exercise. Ten healthy men (19-30 y, 23.6 ± 3.5 y, 174.6 ± 5.7 cm, 78.7 ± 9.9 kg) who were engaged in resistance training at least twice per week but were inexperienced with kettlebell swings participated in this study. Participants were familiarized with the kettlebell swing exercise during an initial visit. During the subsequent experimental protocol visit, participants performed 12 rounds of 30 seconds of 16-kg kettlebell swings alternated with 30 seconds of rest. Heart rate (HR) and rating of perceived exertion (RPE) were measured at the end of every round of swings. Fasted blood samples were collected pre-exercise (PRE), immediately post (IP), 15 minutes post (P15), and 30 minutes post exercise (P30) and analyzed for total testosterone (T), growth hormone (GH), cortisol, and lactate concentrations. Participants completed a total of 227 ± 23 swings (average swings per round: 19 ± 2). HR and RPE increased significantly (P < 0.05) throughout the exercise protocol. Lactate concentrations were significantly increased at all post exercise time points compared to PRE. T was significantly increased at IP compared to PRE. GH was significantly increased at IP, P15, and P30 compared to PRE. Cortisol was significantly increased at IP and P15 compared to PRE. 12 rounds of 30 seconds of kettlebell swing exercise induced an acute increase in T, GH, and cortisol concentrations in resistance trained men. Additionally, this exercise protocol induced a large increase in HR and lactate concentration. Thus, the kettlebell swing exercise might provide an effective method for simultaneous endurance and resistance training.

The Extent of Autism Knowledge of Novice Alternatively Certified Special Education Teachers in Texas

Description: An increase in the prevalence rate of autism is not necessarily matched by a concurrent increase in the rate of highly qualified special education teachers. The low ratio of highly qualified teachers to the number of students with autism has resulted in chronic teacher shortages in this area. Alternative certification is used as a mechanism to alleviate the demand for highly qualified teachers in special education. However, alternative certification routes have often left novice teachers underprepared for teaching students with autism, more specifically in the implementation of evidence-based practices necessary for instructional effectiveness. The purposes of the study were: a) to assess the knowledge of novice alternatively certified (AC) teachers in the area of autism education; and b) to determine the extent to which age, credit hours of instruction, formal hours of instruction, amount of professional development, and number of students with autism predict the variance in knowledge scores. Participants included all novice (i.e., first-and second-year) alternatively certified special education teachers in the state of Texas. Data were collected through an electronic survey instrument disseminated state-wide to approximately 33 individuals. Multiple regression was conducted in order to determine the strongest predictors of autism knowledge scores. In addition, a multi-way ANOVA was performed to identify differences between groups. The largest predictor of knowledge of autism was hours engaged in self-directed learning. Overall, AC programs in Texas need to provide basic and core content in the area of autism to increase the knowledge of novice teachers.

Perceived Parent-child Relationship Quality’s Moderation Effect on the Acculturation-wellbeing Relationship Among Young Adults From Immigrant Families

Description: The current study examined relationships among acculturation, parent-child relationship quality, and selected wellbeing indicators (health-related quality of life, life satisfaction, anxiety, depression, and stress) among a group of young adults from immigrant families of Asian and Hispanic descent. The first goal of the current study was to replicate previous research demonstrating a mixed relationship between acculturation and the wellbeing indicators. The second was to explain this relationship by testing for a moderation effect of parental care on the acculturation-wellbeing relationship. An examination of differences between members of the two ethnic groups on all measured variables served an exploratory purpose. Participants included 204 participants of Asian (N =80) and Hispanic (N = 124) descent who came from an immigrant family, or a family in which at least one parent was born outside of the U.S. Eligible respondents were also current students at the University of the North Texas who fell within the age range of 18-24, and the data for the current study was selected from a larger dataset (N = 1064). Results indicated that higher acculturation levels had a positive effect on each wellbeing indicator. Father Care and Mother Care were found to be significantly positively correlated with most outcome variables but neither parental care variable moderated the acculturation-wellbeing relationship. Asian and Hispanic participants differed on a number of predicting and outcome variables. Implications of the findings, limitations, and future directions are discussed.

Josephus’ Jewish War and the Causes of the Jewish Revolt: Re-examining Inevitability

Description: The Jewish revolt against the Romans in 66 CE can be seen as the culmination of years of oppression at the hands of their Roman overlords. The first-century historian Josephus narrates the developments of the war and the events prior. A member of the priestly class and a general in the war, Josephus provides us a detailed account that has long troubled historians. This book was an attempt by Josephus to explain the nature of the war to his primary audience of predominantly angry and grieving Jews. The causes of the war are explained in different terms, ranging from Roman provincial administration, Jewish apocalypticism, and Jewish internal struggles. The Jews eventually reached a tipping point and engaged the Romans in open revolt. Josephus was adamant that the origin of the revolt remained with a few, youthful individuals who were able to persuade the country to rebel. This thesis emphasizes the causes of the war as Josephus saw them and how they are reflected both within The Jewish War and the later work Jewish Antiquities. By observing the Roman provincial administration spanning 6-66 CE, I argue that Judaea had low moments sprinkled throughout the time but in 66 there was something particularly different, according to Josephus. Josephus presents the governors and other important characters in the war in a very distinct way through rhetoric, narrative, and other methodology. The idea of a beginning to this revolt, no matter how obscure or hidden by Josephus, is the reason I want to examine the works of Josephus the historian.

Adolescent Behavior Problems and Interparental Conflict: the Moderating Role of Parent-child Attachment

Description: The current study examined the role that parent-child attachment plays in the relationship between marital conflict and the development of behavior problems in adolescents. To evaluate the hypothesis that attachment moderates this relationship, 57 families were recruited via e-mail invitation sent to families that participated in local church youth groups, school organizations, and a treatment program designed for adolescents with behavior problems. One custodial parent and his/her adolescent child completed an online or paper version of a survey consisting of the Achenbach’s Behavior Checklists, the Inventory of Parent and Peer Attachment, and the Children’s Perception of Interparental Conflict Scale. Hypotheses were evaluated using Baron and Kenny’s (1986) procedures to test moderating effects with multiple regression analyses. Mother attachment demonstrated a significant moderation effect between the intensity of interparental conflict and the parent’s report of externalizing behavior problems. Specifically, at low conflict intensity levels, relative to low attachment security, high attachment security was associated with fewer externalizing behavior problems, whereas at high intensities of interparental conflict high attachment security was associated with more externalizing behavior problems.

The Effect of Stock Splits on Small, Medium, and Large-sized Firms Before and After Decimalization

Description: This study examines the impact of reducing tick size and, in particular decimalization on stock splits. Based on previous studies, this study examines hypotheses in the following three areas: first, market reaction around stock split announcement and ex-dates, second, the effect of tick size on liquidity after stock split ex-dates, and third, the effect of tick size on return volatility after stock split ex-dates. The impact of tick size on market reaction around split announcement and ex-dates is measured by abnormal returns and buy and hold abnormal returns (BHARs). Also, this study investigates the long term impact of decimalization on market reaction for small, medium, and large firms for the three different tick size periods. The effect of tick size on liquidity after stock split ex-dates is measured by turnover, relative bid ask spread, and market maker count. The effect of tick size on return volatility around stock split announcement and ex-dates is measured by return standard deviation. Also, this study investigates the long term impact of decimalization on volatility after split ex-dates for small, medium, and large firms for three different tick size periods.

Analyzing Delinquency Among Kurdish Adolescents: a Test of Hirschi’s Social Bonding Theory

Description: This study examines the mediating effect of social bonding on delinquent behavior among Kurdish teens. Major influences to the study of self concept and delinquency based on Hirschi’s social bonding theory are reviewed. The data was collected from a sample of 100 Kurdish teens attending a Gülen affiliated school (Private Çaglayan Murat Anatolian Science High School in Şanlıurfa, Turkey) and 100 Kurdish teens attending a public (non- Gülen) school (The Public High School in Diyarbakır, Turkey). There are two dependent variables for this research project: Involvement in major delinquency and involvement in minor delinquency. The components of social bonding attachment, involvement, commitment, and belief were used as independent variables. Participants’ age ranged between 16 to 18 years. I hypothesize that the relation between the social bonding elements and delinquency should be stronger in the case of Kurdish adolescents who are more attached to conventional Turkish society. Results from binary logistic regression analyses indicate that in the absence of bonding, Kurdish teenagers tend to engage in major and minor delinquent activities. For further exploration and results, the Gülen Movement was examined as an independent variable. Findings suggest a strong relationship between the Gülen Movement and Kurdish adolescents’ probability of involvement in either major or minor delinquent activities. Finally, several directions for future research on Hirschi’s social bonding theory are recommended and some implications are drawn for deterring Kurdish adolescents from becoming involved in delinquent actions.

Maximum Likelihood Estimation of Logistic Sinusoidal Regression Models

Description: We consider the problem of maximum likelihood estimation of logistic sinusoidal regression models and develop some asymptotic theory including the consistency and joint rates of convergence for the maximum likelihood estimators. The key techniques build upon a synthesis of the results of Walker and Song and Li for the widely studied sinusoidal regression model and on making a connection to a result of Radchenko. Monte Carlo simulations are also presented to demonstrate the finite-sample performance of the estimators

A New Era of Educational Assessment: the Use of Stratified Random Sampling in High Stakes Testing

Description: Although sampling techniques have been used effectively in education research and practice it is not clear how stratified random sampling techniques apply to high-stakes testing in the current educational environment. The present study focused on representative sampling as a possible means for reducing the quantity of state-administered tests in Texas public education. The purpose of this study was two-fold: (1) to determine if stratified random sampling is a viable option for reducing the number of students participating in Texas state assessments, and (2) to determine which sampling rate provides consistent estimates of the actual test results among the population of students. The study examined students’ scaled scores, percent of students passing, and student growth over a three-year period on state-mandated assessments in reading, mathematics, science, and social studies. Four sampling rates were considered (10%, 15%, 20%, & 25%) when analyzing student performance across demographic variables, including population estimates by socioeconomic status, limited English proficiency, and placement in special education classes. The data set for this study included five school districts and 68,641 students. Factorial ANOVAs were used initially to examine the effects of sampling rate on bias in reading and mathematics scores and bias in percentage of students passing these tests. Also 95% confidence intervals (CIs) and effect sizes for each model were examined to aid in the interpretation of the results. The results showed main effects for sampling rate and campus as well as a two-way interaction between these variables. The results indicated that a 20% sampling rate would closely approximate the parameter values regarding the mean TAKS reading and mathematics scale scores and the percentage of students passing these assessments. However, as population size decreases, sampling rate may have to be increased. For example, in populations with 30 or fewer students in a subgroup it is recommended that ...

The Political, Economic, and Military Decline of Venice Leading Up to 1797

Description: This thesis discusses the decline of the Venetian nobility, the collapse of the Venetian economy, and the political results of the surrender of the Venetian Republic to Napoleon Bonaparte in 1797. Topics include the formation of Venice, Venetian domination of trade, the class system in Venice prior to 1797, the collapse of the aristocracy, feudalism in Venice, Venice’s presence in the Adriatic and Aegean seas, and the rise of the middle class within the provisional democratic government. Very few historians have attempted to research the provisional democracy of Venice and how the political and class structure of Venice changed as a result of the collapse of the Republic in 1797. Using primary sources, including government documents and contemporary histories, one can see how the once dominant noble class slowly fell victim to economic ruin and finally lost their role in the political leadership of Venice all together. During this same period, the middle class went from only holding secretarial jobs within the government, to leaders of a modern democratic movement. On top of primary research, several secondary sources helped in explaining the exclusivity of the noble class and their journey from economic dominance to economic ruin and the administrative consequences of this decline for the people of the Republic. This thesis aims to fill gaps in recent research concerning Venetian political history and specifically the period between the surrender of Venice on 12 May 1797, and the signing of the Treaty of Campo Formio, in which France awarded Venice to Austria, on 18 October 1797.

Investigation of the Pharmacokinetics of Diazepam in Juvenile Channel Catfish (Ictalurus Punctatus)

Description: The presence of pharmaceuticals in the environment is becoming an increasing regulatory and scientific concern. Thus, the metabolic profile and bioconcentration potential of diazepam, a model benzodiazepine, were examined, as well as effects on the endocrine system in channel catfish. Through the use of specific and non-specific cytochrome P450 (CYP450) inhibitors, it was determined that CYP3A-like enzymes may play a role in the biotransformation of diazepam into temazepam; however, the isoform(s) required for the formation of other metabolites is still unknown. Overall, only around 7-8% of diazepam is biotransformed into two known metabolites. Due to the lack of inherent metabolism of diazepam in channel catfish, further analysis was conducted to determine the tissue-specific bioconcentration potential of diazepam in catfish. Various tissues were analyzed for the presence of diazepam as well as metabolites and bioconcentration factors (BCF) were calculated, which were all well below regulatory threshold values (> 2000). Additionally, modulation of the endocrine system by diazepam was examined by measuring steroid hormone concentrations and analyzing mRNA expression of selected steroidogenic enzymes and receptors. Two steroidogenic enzymes were modulated following diazepam exposure, indicating potential endocrine disrupting properties of diazepam. Together, these data suggest that diazepam exhibits low metabolic transformation rates in channel catfish, which may lead to accumulation of benzodiazepine compounds that may negatively affect the endocrine system. However, further studies should be aimed at identifying other steroidogenic enzymes and/or receptors that may be modulated following diazepam exposure.

Molecular and Functional Characterization of Medicago Truncatula Npf17 Gene

Description: Legumes are unique among plants for their ability to fix atmospheric nitrogen with the help of soil bacteria rhizobia. Medicago truncatula is used as a model legume to study different aspects of symbiotic nitrogen fixation. M. truncatula, in association with its symbiotic partner Sinorhizobium meliloti, fix atmospheric nitrogen into ammonia, which the plant uses for amino acid biosynthesis and the bacteria get reduced photosynthate in return. M. truncatula NPF1.7 previously called MtNIP/LATD is required for symbiotic nitrogen fixing root nodule development and for normal root architecture. Mutations in MtNPF1.7 have defects in these processes. MtNPF1.7 encodes a member of the NPF family of transporters. Experimental results showing that MtNPF1.7 functioning as a high-affinity nitrate transporter are its expression restoring chlorate susceptibility to the Arabidopsis chl1-5 mutant and high nitrate transport in Xenopus laevis oocyte system. However, the weakest Mtnip-3 mutant allele also displays high-affinity nitrate transport in X. laevis oocytes and chlorate susceptibility to the Atchl1-5 mutant, suggesting that MtNPF1.7 might have another biochemical function. Experimental evidence shows that MtNPF1.7 also functions in hormone signaling. Constitutive expression of MtNPF1.7 in several species including M. truncatula results in plants with a robust growth phenotype. Using a synthetic auxin reporter, the presence of higher auxin in both the Mtnip-1 mutant and in M. truncatula plants constitutively expressing MtNPF1.7 was observed. Previous experiments showed MtNPF1.7 expression is hormone regulated and the MtNPF1.7 promoter is active in root and nodule meristems and in the vasculature. Two potential binding sites for an auxin response factors (ARFs) were found in the MtNPF1.7 promoter. Chromatin immunoprecipitation-qRT-PCR confirmed MtARF1 binding these sites. Mutating the MtARF1 binding sites increases MtNPF1.7 expression, suggesting a mechanism for auxin repression of MtNPF1.7. Consistent with these results, constitutive expression of an ARF in wild-type plants partially phenocopies Mtnip-1 mutants’ phenotypes.

Pocky Wenches Versus La Pauvre Femme: Medical Perceptions of Venereal Disease in Seventeenth-century England and France

Description: In early modern Europe, syphilis tormented individuals regardless of social standing. The various stages of infection rendered individuals with visible chancres or “pocky” marks throughout their body. The tertiary stage signaled the spreading of the disease from the infected parts into the brain and cardiovascular system, eventually leading to dementia and a painful death. Beginning with the initial medical responses to venereal disease in the sixteenth century and throughout the early modern period, medical practitioners attempted to identify the cause of syphilis. During the seventeenth century, English practitioners maintained that women were primarily responsible for both the creation and transmission of syphilis. In England, venereal disease became the physical manifestation of illicit sexual behavior and therefore women with syphilis demonstrated their sexual immorality. Contrastingly, French medical practitioners refrained from placing blame on women for venereal infection. The historiography of early modern discourse on venereal disease fails to account for this discrepancy between English and French perceptions of syphilis in the seventeenth century. This thesis seeks to fill the gap in this historiography and suggest why French practitioners abstained from singling out women as the primary source of venereal infection by suggesting the importance that cultural influences and religious practices had toward shaping medical perceptions. The cultural impact of the querelle des femmes and Catholic practices in France plausibly influenced the better portrayal of women within the medical treatises of seventeenth-century France when compared to Protestant England.

Evaluating the Cultural Plan of Austin, Texas

Description: This is a concurrent, mixed methods study of the impacts of Austin, Texas’s cultural plan, CreateAustin. In the study, trend analysis and a t-test were used to examine variables before and after the cultural plan was in place. At the same time, interviews with cultural planners were used to uncover other effects. My research addresses a gap in the literature between understanding the desired and actual outcomes of a cultural plan. Cultural plans are being developed by many communities in an effort to attract creative workers but they are rarely evaluated. Evaluation using a mixed methods approach is necessary to capture all the outcomes of a cultural plan, rather than the limited scope of impacts that are captured by qualitative or quantitative analyses alone. My analysis of the quantitative variables showed some significant differences between when the plan was in place and the years prior to its creation. Interviews with key stakeholders revealed the formation of new networks as a powerful outcome of the planning process. The results allowed me to gauge the overall impact of CreateAustin and make some observations about the cultural planning process in general, as well as uncover new directions for future research.

Grace After Fire: an Analysis of Table Talk: Color Me Camo-realities of Female Veterans

Description: Beginning May of 2013 and ending in September, I worked with Grace After Fire (Grace), a virtual nonprofit organization that focuses on issues related to female veterans. Grace’s mission is to provide female veterans with the means to gain knowledge, insight and self-renewal. Grace’s mission is accomplished through peer support and resource referral. The aim of my thesis project was to conduct an analysis of Grace’s peer support system, Table Talk: Color Me Camo (Table Talk). Because Table Talk is a fairly new program for Grace, just over a year old, the outreach coordinators were eager to learn: 1) if they were indeed meeting their mission of empowering female veterans, and 2) the point-of-view of the peer facilitators who conduct Table Talk. To help Grace gain perspective, I interviewed women who had previously attended Table Talk, as well as peer facilitators responsible for coordinating the peer support system-all of whom are female veterans. The following is their story.

Funds of Knowledge in a Hispanic Household: a Case Study of Family Experiences, Values, and Connections to Education

Description: Traditionally, the field of education has often adopted a negative perspective in their views of minority families’ contributions to the educational progress of their children. However, research embodying the theoretical framework of ‘funds of knowledge’ attempts to counter that model through its assertion that all families possess extensive bodies of knowledge that have developed through social, historical, and cultural contexts. Teachers carry out studies of familial funds of knowledge in order to understand how family experiences shape the knowledge that a child brings to the classroom. There is then, the potential to use that body of knowledge to create meaningful learning experiences that connect prior understanding and experiences to classroom practice. This research served as a case study of the funds of knowledge existing in the home of a Hispanic family and the connections that existed between that knowledge and literacy. The results indicated that the family possessed extensive funds of knowledge that developed through their historical, cultural, and social experiences. They often used family networks, as well as formal and informal literacy experiences to share this knowledge with their children. A key component of the literacy value system that they communicated resulted from a desire to maintain aspects of their culture and heritage through maintaining and improving their children’s reading and linguistic abilities in Spanish. Furthermore, along with their emphasis on Spanish literacy, they held aspirations for their children related to familial and educational values that often stemmed from their expressed desire for their children to lead lives with greater opportunities and positive examples than they had experienced.

A Comprehensive Modeling Framework for Airborne Mobility

Description: Mobility models serve as the foundation for evaluating and designing airborne networks. Due to the significant impact of mobility models on the network performance, mobility models for airborne networks (ANs) must realistically capture the attributes of ANs. In this paper, I develop a comprehensive modeling framework for ANs. The work I have done is concluded as the following three parts. First, I perform a comprehensive and comparative analysis of AN mobility models and evaluate the models based on several metrics: 1) networking performance, 2) ability to capture the mobility attributes of ANs, 3) randomness levels and 4) associated applications. Second, I develop two 3D mobility models and realistic boundary models. The mobility models follow physical laws behind aircraft maneuvering and therefore capture the characteristics of aircraft trajectories. Third, I suggest an estimation procedure to extract parameters in one of the models that I developed from real flight test data. The good match between the estimated trajectories and real flight trajectories also validate the suitability of the model. The mobility models and the estimation procedure lead to the creation of “realistic” simulation and evaluation environment for airborne networks.
