Asperger's Syndrome And Learning Strategies: Are Difficulties Due To A Production Deficit Or To A Utilization Deficit?, Miranda Lee Morris Apr 2011

Asperger's Syndrome And Learning Strategies: Are Difficulties Due To A Production Deficit Or To A Utilization Deficit?, Miranda Lee Morris

Theses and Dissertations

This study investigated whether knowledge about memory strategies was impaired in a group of young adults with Asperger’s Syndrome (AS) as compared to a group of young adults without AS. Both groups participated in two tasks, one designed to examine the categorization strategy and one to examine the interactive imagery strategy. Participants with AS showed a production deficit because they were unable to spontaneously produce either strategy to benefit their memory performance. However, the group with AS did not show evidence of a utilization deficit; when they were trained on strategies, they were able to use them effectively both immediately …

Moving In A Hierarchized Landscape; Changing Border Regimes In Central Kalimantan, Dave Lumenta Apr 2011

Moving In A Hierarchized Landscape; Changing Border Regimes In Central Kalimantan, Dave Lumenta

Wacana, Journal of the Humanities of Indonesia

Transnational mobility is a common feature among borderland communities. Central Borneo has been a relatively fluid and open riverine-based socio-cultural and economic space since the arrival of colonial states, without much interference from the establishment of international boundaries on local cross-border mobility practices. This applies to the Kenyah, a cluster of related ethnic groups occupying the Apokayan plateau in East Kalimantan (Indonesia), who are historically an integral part of the socio-cultural and economic fabric throughout the major riverine systems of Sarawak (Malaysia). Despite the relative absence of states, Central Borneo has not escaped the onslaught of social differentiation embedded in …

Crossing The Border; Historical And Linguistic Divides Among The Bunaq In Central Timor, Antoinette Schapper Apr 2011

Crossing The Border; Historical And Linguistic Divides Among The Bunaq In Central Timor, Antoinette Schapper

Wacana, Journal of the Humanities of Indonesia

The Bunaq are a Papuan language-speaking people straddling the border of Indonesian West Timor and independent East Timor. This paper looks at the history of the Bunaq as a "border" people in Timor. "Border" is interpreted here in two ways, as referring to: (i) a political division, the boundary line separating one country from another, and (ii) a linguistic division, the distinguishing line between Papuan and Austronesian languages. I examine the effect that the Bunaq position at the political and linguistic borders of Timor has had on the people and their language.

Oxidative Stress Induces Dna Strand Breaks May Lead To Genomic Instability In Ovarian Tumorigenesis, Harold-Humberto Moreno-Ortiz Apr 2011

Oxidative Stress Induces Dna Strand Breaks May Lead To Genomic Instability In Ovarian Tumorigenesis, Harold-Humberto Moreno-Ortiz

Theses and Dissertations

Oxidative stress (OS) occurs when DNA repair mechanisms are overcome by the amount of single and double strand DNA breaks caused by an accumulation of reactive oxygen species (ROS). Genomic instability (GI) by microsatellite instability (MSI) accumulation is characterized by changes in DNA single tandem repeats (STR) as a direct result of ROS. Deregulation of DNA repair and tumor suppressor pathways have been described as causes of tumor progression and metastasis. Studies in mammals have focused on GI and the implications of increased mutation frequency due to accumulation of MSI leading to development of diseases, including infertility and cancer. Ovarian …

Functional Complementation Analysis Of Fungal Rtg2 Homologs In Saccharomyces Cerevisiae, Ercan Selcuk Unlu Apr 2011

Functional Complementation Analysis Of Fungal Rtg2 Homologs In Saccharomyces Cerevisiae, Ercan Selcuk Unlu

Theses and Dissertations

Changes in gene expression in response to mitochondrial dysfunction are mediated by components of the retrograde signaling pathway. The mitochondrial signal is recognized and transferred to the nucleus by dynamic interactions between regulatory proteins Rtg2p, Mks1p and Bmh1p. Retrograde signaling genes have been well characterized in the budding yeast Saccharomyces cerevisiae but very little is known about the retrograde response of other fungi. To identify retrograde signaling proteins in other fungi, the protein sequence encoded by the S. cerevisiae RTG2 gene was used to search for fungal homologs using NCBI BlastP and the T-Coffee Multiple Sequence Alignment program. We selected …

Deoxygenation Catalysis On Titania For Renewable Fuel Applications, Prashant Reuben Daggolu Apr 2011

Deoxygenation Catalysis On Titania For Renewable Fuel Applications, Prashant Reuben Daggolu

Theses and Dissertations

This research studies the use of class=SpellE>titania (titanium dioxide, TiO2) as a catalyst for deoxygenation of class=SpellE>syngas derived oxygenates. These oxygenates are formed as byproducts when biomass derived syngas (CO & H2) is converted to ethanol on Rhodium or Molybdenum based catalysts. Conversion of these oxygenates to hydrocarbon would enhance the viability of class=SpellE>syngas to gasoline technology. This study revealed that class=SpellE>titania can indeed be used to convert syngas derived oxygenates to hydrocarbon at high temperature and pressure. Acetone condensation to mesitylene was studied very closely. The study revealed that the acid-base dual nature of class=SpellE …

Consequences Of Gis Classification Errors On Bias And Variance Of Forest Inventory Estimates, Michael Keith Crosby Apr 2011

Consequences Of Gis Classification Errors On Bias And Variance Of Forest Inventory Estimates, Michael Keith Crosby

Theses and Dissertations

The use of remotely sensed imagery (e.g. Landsat TM) for developing forest inventory strata has become increasingly more common in recent years as data have become more readily available. Errors are inherent with the use of this technology, either from user mis-classification of conditions represented in the imagery or due to flaws in the technology. Knowledge of these errors is important, as they can inflate the variance of inventory estimates. Forest inventory estimates from the Mississippi Institute for Forest Inventory (MIFI) were applied to determine the extent that classification errors affect volume and area estimates. Forest strata (e.g. hardwood, mixed, …
