His, Hers, and Theirs: Domestic Relations and Marital Property Law in Texas to 1850 (open access)

His, Hers, and Theirs: Domestic Relations and Marital Property Law in Texas to 1850

Texas law regarding the legal status of women and their property rights developed from the mingling of Spanish and English laws. Spanish laws regarding the protection of women's rights developed during the centuries-long Reconquest, when the Spanish Christians slowly took back the Iberian Peninsula from the Moorish conquerors. Women were of special importance to the expansion of Spanish civilization. Later, when Spain conquered and colonized the New World, these rights for women came, too. In the New World, women's rights under Spanish law remained the same as in Spain. Again, the Spanish were spreading their civilization across frontiers and women needed protection. When the Spanish moved into Texas, they brought their laws with them yet again. Archival evidence demonstrates that Spanish laws in early Texas remained essentially unchanged with regard to the status of women. Events in the history of England caused its legal system to develop in a different manner from Spain's. In England, the protection of property was the law's most important goal. With the growth of English common law, husbands gained the right to control their wives's lives in that married women lost all legal identity. When the English legal system crossed the Atlantic and took root …

Functions of self-injurious thoughts and behaviors within adolescent inpatients. (open access)

Functions of self-injurious thoughts and behaviors within adolescent inpatients.

The primary interest of this investigation concerned the self-injurious thoughts and behaviors (SITBs) of inpatient adolescents. Previous researchers have provided descriptive information regarding either automatic (or intrinsic) and social components using the Self-Injurious Thoughts and Behaviors Interview (SITBI). However, the presence and trends of these components have not firmly been established, suggesting the need to explore this area further. Eighty-two adolescent inpatients were selected and interviewed using the SITBI to evaluate the predictive ability of self-reported self-injurious behavior with regard to social and automatic, negative and positive functions. Results showed that depending on the type of thought or behavior displayed one could discern the motivation behind their actions. Automatic-Negative was seen to have the strongest relationship across all SITB behaviors while Automatic-Negative was not found to be relatively low compared to other SITB behaviors. Both Social-Positive and Social-Negative were found to be present in moderate relationships compared to Automatic in general.

Analysis of the Accumulation, Toxic Effects, and Risk of Persistent Organic Pollutants in Pinnipeds (open access)

Analysis of the Accumulation, Toxic Effects, and Risk of Persistent Organic Pollutants in Pinnipeds

The present studies determine the accumulation of persistent organic pollutants (POPs) in three pinniped species, evaluate the relationship with relevant biomarkers of exposure, and calculate toxic effect thresholds. Stranded harp and hooded seals were found to be accumulating PBDEs at levels which could pose a based on threshold levels determined in this study. Northern fur seals are accumulating all three classes of POPs (PCBs, PBDEs, and OCPs) with significant relationships being seen with blubber percent lipid. Correlations between contaminant concentrations and expression levels of relevant biomarkers were seen potentially indicating an effect on multiple pathways. Overall risk can be hard to determine due to factors such as sex and age. Broad threshold response values and hazard quotients were calculated for toxic effect endpoints in pinnipeds. Overall these results suggest that certain populations of pinnipeds are at high risk of experiencing toxic effects due to POP exposure, but it is important to understand effects even at lower concentrations. The relationship between exposure, toxic effects, and other stressors, both environmental and physiological, can impact the overall fitness and survival of pinnipeds.

A Comparison of Psychological and Physiological Components of Migraine and Combination Headaches (open access)

A Comparison of Psychological and Physiological Components of Migraine and Combination Headaches

To aid in understanding headache etiology and symptomatology, psychological and physiological variables were examined in patients with migraine and combination headaches (combined migraine and muscle-contraction headaches). One hundred patients being evaluated for treatment of their headaches at The New England Center for Headache participated in this study. They were assigned to the migraine or combination group, based on diagnoses made by three headache specialists—a psychologist, a psychiatrist, and a nuerologist. Personality data from the MMPI and frontalis electromyographic readings reflecting muscle tensions across three stimulus conditions were compared between the two groups. Subjects were also asked to rate the perceived level of stress elicited by the three conditions.

Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems (open access)

Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems

The current study discussed the development and validation of the Checklist for Differential Diagnosis of Attentional Problems (CDDAP), a tool for use with adults seeking diagnosis and treatment of an Attention Deficit Hyperactivity Disorder. Normative data are provided on three subject groups (ADHD adults, controls, and adults with other psychiatric disorders). Convergent validity was established with the SCL-90, and criterion validity established through comparing scaled scores with final diagnoses. Overall, this measure was accurate at differentiating adults with ADHD from controls and adults with other psychiatric disorders. Results indicated that the CDDAP was also able to identify other psychiatric disorders with 71 to 92% accuracy, depending on the disorder.

The Online and the Onsite Holocaust Museum Exhibition as an Informational Resource

Museums today provide learning-rich experiences and quality informational resources through both physical and virtual environments. This study examined a Holocaust Museum traveling exhibition, Life in Shadows: Hidden Children and the Holocaust that was on display at the Art Center of Battle Creek, Michigan in fall 2005. The purpose of this mixed methods study was to assess the informational value of a Holocaust Museum exhibition in its onsite vs. online format by converging quantitative and qualitative data. Participants in the study included six eighth grade language arts classes who viewed various combinations or scenarios of the onsite and online Life in Shadows. Using student responses to questions in an online exhibition survey, an analysis of variance was performed to determine which scenario visit promotes the greatest content learning. Using student responses to additional questions on the same survey, data were analyzed qualitatively to discover the impact on students of each scenario visit. By means of an emotional empathy test, data were analyzed to determine differences among student response according to scenario visit. A principal finding of the study (supporting Falk and Dierking's contextual model of learning) was that the use of the online exhibition provided a source of prior orientation and …

Fire Eater in the Borderlands: The Political Life of Guy Morrison Bryan, 1847-1891

From 1847 to 1891, Guy Morrison Bryan was a prominent Texas politician who influenced many of the policies and events that shaped the state. Raised in his Uncle Stephen F. Austin's shadow, he was a Texas nationalist who felt responsible for promoting the interests of his state, its earliest settlers, and his family. During his nineteen years in the Texas Legislature and two years in the United States House of Representatives, he safeguarded land grants, supported internal improvements and education, and challenged northern hostility towards slavery. Convinced that abolitionists would stop at nothing to destroy the institution and Texas, he led his state's walkout of the National Democratic Convention in 1860 and became a leading proponet of secession. During the Civil War, he served as a staff officer, and his ability to mediate conflicts between local and national leaders propped up the isolated Confederate Trans-Mississippi Department. Finally as Speaker of the House, he helped oust Governor Edmund J. Davis in 1874 and "redeem" the state from Republican rule before convincing President Rutherford B. Hayes to adopt a conciliatory policy towards Texas and the South. Despite the tremendous influence Bryan wielded, scholars have largely ignored his contributions. This dissertation establishes his …

Assessment of Feigned Neurocognitive Impairment in Retired Athletes in a Monetarily Incentivized Forensic Setting

Compromised validity of test data due to exaggeration or fabrication of cognitive deficits inhibits the capacity to establish appropriate conclusions and recommendations in neuropsychological examinations. Detection of feigned neurocognitive impairment presents a formidable challenge, particularly for evaluations involving possibilities of significant secondary gain. Among specific populations examined in this domain, litigating mild traumatic brain injury (mTBI) samples are among the most researched. One subpopulation with potential to contribute significantly to this body of literature is that of retired athletes undergoing fixed-battery neuropsychological evaluations within an assessment program. Given the considerable prevalence of concussions sustained by athletes in this sport and the substantial monetary incentives within this program, a unique opportunity exists to establish rates of feigning within this population to be compared to similar forensic mTBI samples. Further, a fixed battery with multiple validity tests (VT) offers a chance to evaluate the classification accuracy of an aggregated VT failure paradigm, as uncertainty abounds regarding the optimal approach to the recommended use of multiple VTs for effort assessment. The current study seeks to examine rates of feigned neurocognitive impairment in this population, demonstrate prediction accuracy equivalence between models based on aggregated VT failures and logistic regression, and compare classification performance of …

Muscle Tension and Locus Of Pain in Subjects With and Without Chronic Backpain (open access)

Muscle Tension and Locus Of Pain in Subjects With and Without Chronic Backpain

The purpose of the study is to examine the relationship between the location of the initial onset of back pain as revealed by the subject's pain drawing and the site of maximum muscle tension at rest, while jaw-clenching and during a cold stressor, in men and women. Subjects were 30 males and 30 females divided into three groups of 10 males and 10 females each and designated according to back pain history as no back pain (NBP), upper back pain onset (UBP) and lower back pain onset (LBP). Six bipolar, bilateral electromyographic (EMG) recording sites were instrumented on each subject. EMG levels were recorded from the forehead, forearm, upper back, lower back, thighs and ankles under conditions of rest, jaw-clenching and a cold stressor. Seven hypotheses predicted that EMG levels would distinguish groups and gender of the subjects and that interactions would exist between site of pain onset and EMG elevations.

Schools and Schoolmen: Chapters in Texas Education, 1870-1900 (open access)

Schools and Schoolmen: Chapters in Texas Education, 1870-1900

This study examines neglected aspects of the educational history of Texas. Although much emphasis has been placed on the western, frontier aspects of the state in the years after Appomattox, this study assumes that Texas remained primarily a southern state until 1900, and its economic, political, social, and educational development followed the patterns of the other ex-Confederate states as outlined by C. Vann Woodward in his Origins of the New South. This study of the educational history of Texas should aid in understanding such developments for the South as a whole. For the purposes of this study, "education" is defined in terms of institutions specifically created for the formal education of the young. Additionally, the terms "public education" and "private education" are used extensively. It is a contention of this study that the obvious differences between public and private schools in the last half of the twentieth century were not so obvious in the last half of the nineteenth, at least in Texas. Finally, an attempt has been made to confine the study to those areas of formal schooling which are today commonly called primary and secondary, although this was difficult because of the lack of definition used in naming …

A.P. Giannini, Marriner Stoddard Eccles, and the Changing Landscape of American Banking

The Great Depression elucidated the shortcomings of the banking system and its control by Wall Street. The creation of the Federal Reserve System in 1913 was insufficient to correct flaws in the banking system until the Banking Acts of 1933 and 1935. A.P. Giannini, the American-Italian founder of the Bank of America and Mormon Marriner S. Eccles, chairman of Federal Reserve Board (1935-1949), from California and Utah respectively, successfully worked to restrain the power of the eastern banking establishment. The Banking Act of 1935 was the capstone of their cooperation, a bill that placed open market operations in the hands of the Federal Reserve, thus diminishing the power of the New York Reserve. The creation of the Federal Housing Act, as orchestrated by Eccles, became a source of enormous revenue for Giannini. Giannini's wide use of branch banking and mass advertising was his contribution to American banking. Eccles's promotion of compensatory spending and eventual placement of monetary control in the hands of the Federal Reserve Board with Banking Act of 1935 and the Accord of 1951 and Giannini's branch banking diminished the likelihood of another sustained depression. As the Bank of America grew, and as Eccles became more aggressive in …

The Way of Change and Surprise: A Strategic Cultural Analysis of China's South China Sea Policies from the 1930s to 2010s

This dissertation aims to discover the hidden pattern and rationales behind China's South China Sea policies over the last one hundred years from the perspective of Chinese strategic culture. A historical-cultural approach is a powerful tool in uncovering deeper understandings of the Chinese way of policy making and strategy on issues such as the South China Sea. The key research questions include: first, is there any historical legitimacy in China's sovereignty claim over the South China Sea islands? Second, do Beijing's South China Sea policies in various periods have any regularity or pattern, and how did they serve China's grand strategies at the time? By utilizing extensive Chinese and English primary sources and other sources, this study conducts a comprehensive and in-depth analysis of the South China Sea issue from the framework of Chinese strategic culture.

Between Comancheros and Comanchería: a History of Fort Bascom, New Mexico (open access)

Between Comancheros and Comanchería: a History of Fort Bascom, New Mexico

In 1863, Fort Bascom was built along the Canadian River in the Eroded Plains of Territorial New Mexico. Its unique location placed it between the Comanches of Texas and the Comancheros of the Sangre de Cristo Mountains. This post was situated within Comanchería during the height of the United States Army's war against the Southern Plains Indians, yet it has garnered little attention. This study broadens the scholarly understanding of how the United States Army gained control of the Southwest by examining the role Fort Bascom played in this mission. This includes an exploration of the Canadian River Valley environment, an examination of the economic relationship that existed between the Southern Plains Indians and the mountain people of New Mexico, and an account of the daily life of soldiers posted to Fort Bascom. This dissertation thus provides an environmental and cultural history of the Canadian River Valley in New Mexico, a social history of the men stationed at Fort Bascom, and proof that the post played a key role in the Army's efforts to gain control of the Southern Plains Indians. This study argues that Fort Bascom should be recognized as Texas' northern-most frontier fort. Its men were closer to …

Depression and Heart Rate Variability in Patients with Coronary Artery Disease (open access)

Depression and Heart Rate Variability in Patients with Coronary Artery Disease

Depression is an independent risk factor for morbidity and mortality in patients with coronary artery disease (CAD). Altered autonomic nervous system (ANS) activity, a common feature of depression, is also a risk factor for cardiac events in patients with CAD. Heart rate variability (HRV) reflects ANS activity, and reduced HRV predicts morbidity in cardiac populations. The purpose of this study was to determine whether differences in HRV exist between depressed and nondepressed patients with CAD. Twenty-one depressed inpatients, with angiographically documented CAD were retrospectively matched to 21 nondepressed CAD patients by sex, age, and smoking status. Demographic, medical, psychological interview data, and 24-hour ECG recordings were obtained. Depressed subjects had significantly lower HRV, or trends toward lower HRV, than nondepressed subjects, even after controlling for severity of CAD. Subject groups did not differ on left ventricular ejection fraction, history of myocardial infarction, or any other relevant medical variable assessed. These results suggest that depression is associated with decreased HRV in patients with CAD, and may help to explain the increased rates of cardiac events observed in CAD patients with depression.

Effects of Cautioning and Education in the Detection of Malingered Mild Traumatic Brain Injury

This study examined the effectiveness of cautioning and education on simulating a mild traumatic brain injury on several neuropsychological measures. The measures used included the Word Memory Test (WMT), Wechsler Adult Intelligence Scales® - Third Edition (WAIS®-III), Wechsler Memory Scales®-3rd Edition instrument (WMS®-III), 16-item version of the Rey Memory Test, and a self-report symptom checklist. Five experimental groups were used including clinical and non-clinical controls, as well as three simulation groups. The design and implementation of this study also attempted to correct several methodological short comings of prior research by increasing the incentives for participants, expanding the generalizability of findings and examining research compliance and participant self-perception through debriefing. Discriminant analysis was utilized to determine if specific functions existed that would correctly classify and distinguish each experimental group. Several discriminant functions had at least moderate canonical correlations and good classification accuracy. Results also include utility estimates given projected varying base rates of malingering.

The History, Modern Development, and Future of the Lutheran Theological Seminary (Hong Kong)

This study is an historical and institutional analysis of The Lutheran Theological Seminary (LTS) in Hong Kong. The study first traces the seminary's theological and missiological roots and its history from 1913 to 1948, from its founding in Hubei Province, China to its move to Hong Kong because of civil war. Next, it describes major events of the early years in Hong Kong and the factors which contributed to an institutional crisis in the late 1960's. The study then analyzes the modern development of the institution, specifically the years 1971 to 1993. During this period several regional church groups joined together to create a collaborative educational effort through LTS, the school gained regional accreditation, expanded the ranks of its Chinese faculty, developed Asian financial support, and constructed a new campus. The modern development of the institution cannot be understood apart from a comprehension of the twenty-two year administration of Andrew Hsiao, the first Chinese president of the school. A chapter is therefore included on Andrew Hsiao's personal and academic background, the distinctives of his administration, and the strengths and weaknesses of his presidency. A current profile of the school is provided including its purposes, theology, organizational structure, faculty, student body, …

Life Stress and Adjustment: Effects of Cognitive Content and Cognitive Organization

Individual differences of cognitive organization and content were investigated as they relate to adaptation to remote, recent, and immediate life stress. Outside the field of stress, prior researchers have implicated cognitive organization with adjustment and cognitive content with specific psychopathology. As for behavioral adaptation to life stress, cognitive organization was viewed as a major factor in emotional vulnerability and adjustment, and cognitive content as a major factor in the mood disturbance of depression. Behavioral adaptation was defined in terms of current emotional vulnerability, adjustment and negative changes in the immediate (last six months), recent (over six months), and remote (over one year) past.

NEPSY profiles in children diagnosed with different ADHD subtypes.

The purpose of this study was to determine if attention-deficit/hyperactivity disorder (ADHD) subtypes (predominantly hyperactive/impulsive, ADHD-HI; predominantly inattentive, ADHD-IA; combined, ADHD-C) exhibit distinct neuropsychological profiles, using the Attention and Executive Function subtests of the Developmental Neuropsychological Assessment, (NEPSY) and the omission and commission scores obtained on the Conners' Continuous Performance Test-II (CPT-II), a test that assesses attention processes. The sample was selected using archival data collected in a neurodevelopmental clinic over the past decade and consisted of 138 children between the ages of 6 and 12 years old. Using the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) criteria, the children were placed in either the ADHD-HI (n = 40), ADHD-IA (n = 35), or ADHD-C (n = 36) group, or a symptom free comparison group (n = 27). It was hypothesized that children with elevations on the impulsivity/ hyperactivity (ADHD-HI and ADHD-C) scale would be impaired on measures of inhibition and those with elevations on the inattention scale (ADHD-IA and ADHD-C) would be impaired on tests of attention, vigilance, and other executive functions.

Feigning Cognitive Deficits on Neuropsychological Evaluations: Multiple Detection Strategies (open access)

Feigning Cognitive Deficits on Neuropsychological Evaluations: Multiple Detection Strategies

Individuals undergoing forensic neuropsychological evaluation frequently stand to gain in some manner if neurocognitive dysfunction is diagnosed. As a result, neuropsychologists are customarily asked to test for neurocognitive feigning during the assessment. The current study employed an analogue design with a clinical comparison group to examine the utility of the TOCA (Rogers, 1996) as a measure of feigned neurocognitive impairment. Two groups of simulators (one cautioned about the presence of detection strategies and one not cautioned) were compared to clinical and normal control groups. Fourteen scales were developed based on five detection strategies: symptom validity testing, performance curve, magnitude of error, response time, and floor effect. Each was employed during both verbal and nonverbal tasks. Significant differences were revealed among groups when subjected to ANOVA. Classification rates from subsequent utility estimates and discriminant function analyses on the scales ranged from 58.8% to 100%. Combining strategies yielded a classification rate of 95.7%. The effect of cautioning simulators was modest; however, a trend was noted on some scales for cautioned simulators to appear less obviously impaired than noncautioned. Although the results require crossvalidation, preliminary data suggest that the TOCA is a sensitive and specific measure of feigned neurocognitive performance. Strengths and weaknesses …
