Chicano y Chicana: income differences among the largest U. S. Hispanic population
This study focuses on the wage gap between Mexican American men and Mexican American women, and factors contributing to this disparity. People of Mexican descent make up 67% of the U.S. Hispanic population. Previous research tends to lump Hispanics together, masking differences between groups. Even more, studies considering Hispanic subgroups rarely examine gender differences on income. Using secondary data analysis of the March 2005 Current Population Survey Annual Social and Economic Supplemen
Application of stochastic control and robust stability of singularly perturbed unified systems
The unified approach and singular perturbation theories are two of the most highly recognized and rapidly developed areas in the control field recently. In this thesis, a stochastic optimal controller design using state feedback is examined for singularly perturbed unified systems with Gaussian noise. The difference between the costs of full order systems and those of reduced order systems is just on the order of epsilon. The robust of a singularly perturbed unified stochastic system is investig

The effects of phonotactic and orthotactic probabilities on orthographic fast-mapping in kindergarte
The purpose of this study was to investigate how the linguistic components of phonotactic and orthotactic probability affected children’s ability to fast-map orthographic information and whether orthographic processing explained unique variance on children’s literacy skills above and beyond that of phonological processing. Moreover, the current study examined whether kindergarten children with and without typical language abilities were differentially affected by linguistic processes on read
Where the two kingdoms merge: the struggle for balance between national and religious identity among
When the German Reich was created in 1871, it was an artificial construct born of Hohenzollern power projection and not of nationalism. Otto von Bismarck’s Realpolitik used the power of nationalism to unite Germans behind the Kaiser, but also divisively to keep liberals and potential opponents of the Kaiser firmly divided. The Kulturkampf was one such set of policies that attempted to suppress Catholic political authority while dividing Germany’s religious groups against one another. The Kul
Novel inhibitors of human leukocyte proteinase 3
Chronic obstructive pulmonary disease (COPD) is a multifactorial disorder that is associated with an influx of macrophages, neutrophils and T-lymphocytes to the lungs and the extracellular release of several proteases, including serine (proteinase 3, elastase, cathepsin G), cysteine (cathepsin S) and metallo- (macrophage metalloelastase, MMP-12) proteases, leading to a protease/antiprotease imbalance. The pathogenesis of COPD arises from an imbalance between the levels of proteases and their end
The end and the beginning:a model for analyzing visual/verbal news broadcasts of protest coverage
This project brings together two areas of prior research: framing and visual rhetoric. Framing as it relates to news coverage of protests constitutes the core theoretical foundation. In using prior research by McLeod, Gitlin, and Lee, we see how news coverage can potentially bias an audience against protestors. However, this research focuses extensively on newspapers or transcripts of televised news. Consequently, by combining visual theories like semiotics, gestalt, and film theory into a visua
Will you be my friend? An analysis of friendster.com
Friendster.com was launched in California in 2002 with 20 users. Today, it has more than 27 million members and it is especially popular among Southeast Asian women. It differs from other online dating sites in that users must be approved before they can become part of a user’s personal network. This study explores what may have made the site so attractive, as well as how its users represent themselves in their personal profiles. Drawing on social constructionist and feminist theories, this th
The first year impact of a professional learning community on low achieving 7th and 8th grade studen
The purpose of this study was to measure the impact on low achieving learners within the first year implementation of a professional learning community in a large suburban middle school located in the Midwest. Interventions through collaborative efforts were devised for low achieving learners and implemented. Grade trends for students earning below average and failing grades in all subject areas in the 7th and 8th grade were examined from each quarter of the previous four years and compared to g
Literature circles in the high school setting: an inquiry from comprehension to synthesis
The purpose of this study is to determine the efficacy of literature circles in a high school English classroom setting. Specifically, the purpose of this is to determine if literature circles improve reading comprehension and student involvement in reading and class discussions. As a sub-inquiry of this study, it is the purpose of this researcher to determine if the prescribed roles often used as guidelines for literature circles create perfunctory responses in small group discussions, and if i
The effects of higher-level questioning in a high school mathematics classroom
The purpose of this study was to address questioning and higher-level thinking in a low level high school mathematics class. Students in this study included twenty-two high school freshmen (experimental group) and twenty-three high school freshmen (control group) who were enrolled in Algebra 1. This study included a pretest that both groups took to determine their cognitive level or thinking prior to new information and modifications in teaching. The experimental group received modifications tha
Building a testbed for mini quadrotor unmanned aerial vehicle with protective shroud
Potential applications of small rotorcraft unmanned aerial vehicles (UAVs) range from military missions to exploration of the planet Mars (Patrick C. O’Brien, 2003). Tasks such as exploration of unknown territories, formation flying, intelligence gathering etc, require UAV to be capable of flying very close to other flying or steady objects. Exposed rotary wings limit rotorcraft vehicle’s capability to fly in proximity of other objects. In some applications, such as rescue operation, urban w
The effects of explicit teaching of morphemic analysis on vocabulary learning and comprehension and
This study investigated the effects of explicit teaching of morphemic analysis on vocabulary learning and comprehension and its transfer effects to novel words with sixth grade students. Because research states that vocabulary and the ability to decode unfamiliar words is vital for comprehension, an increase in vocabulary learning and comprehension was predicted. A sixth-grade reading class with low reading assessment results was specifically taught twelve affixes and roots chosen from a bank of
Analysis of honeycomb core properties under different parametric conditions for the head injury crit
There has been enormous boom in the air travel in recent times. There is increasing demand for the technological advancement nowadays towards the safety of the onboard passengers. Certification of aircrafts requires engineers to demonstrate that a head contact with any aircraft interior complies with the Head injury criteria (HIC) threshold of 1000 units specified in 14CFR 23.562, 25.562, 27.562. Analyzing injuries to the head of the occupant when it comes to contact with any aircraft cabin inte
Finite element modeling of energy absorption characteristic of hybrid structure - composite wrapped
The study of axial crush behavior of metal and composite tube has become a basis for the design of crashworthy structure in automotive and aircraft applications. Unlike metals, polymer composite material displays little or no plastic deformation characteristics. Research has showed that the hybrid tube usually made of inner aluminum tube over-wrapped with Eglass fiber reinforced epoxy have significantly higher energy absorption than either aluminum tube or composite tube. It is therefore importa
Are women still experiencing gender discrimination in income and employment positions?
The purpose of this research is to examine the gender pay-gap and the potential factors that contribute to income inequality. Since passing the Equal Pay Act the median weekly earnings of women is still just $0.72 for every dollar men earn. To put this in context the pay-gap in 1970 was $0.62 and in 1992 it was $0.75 (Institute for Women’s Policy Research, 1993). Secondary data analysis of the 2003 American Time Use Survey purports the potential reasons why the pay-gap still continues. This re
Protective bollard design for high speed impact energy absorption
As is passenger safety of paramount importance to the manufacturer of passenger vehicles, so is the security of the nation to its government. Recent developments in the usage of heavy vehicles by militant outfits to carry out attack has become the main concern of many governments around the world, hence the existence of some kind of barrier to stop heavy vehicles from entering restricted areas was thought of. This barrier must be able to provide both visibility and security without being much ex
Parametric study of low velocity impact analysis on composite tubes
As explicit finite element codes improve and advanced material models become available, such tools find more widespread application in many industries. This thesis reports the research study of the low velocity impact simulation on carbon reinforced polymer epoxy composite tube using nonlinear explicit finite element software LS-Dyna. Validation of the experimental results is done with the proposed finite element model in LS-Dyna. A finite element model is implemented on quadratic stress based g
