With this thesis I will focus on my Chicano artistic influences as well as on my life experiences as a third-generation Chicano growing up in the barrios of Browntown, “Tejas” (Brownsville, Texas) I will also examine in my paintings the Chicano identity; its culture, traditions, beliefs, and lifestyle. In this thesis like my artwork I will depict the myth of “Atzlan” via eras of the Chicano movement. I will start my writings with the mid-nineteen forties, the “Zoot Suit” era, which I believe is the original beginning of the Chicano movement, and advance to the nineteen sixties and seventies where …

Quest For Spirituality, Teodoro Estrada

Theses and Dissertations - UTB/UTPA

Quest for Spirituality is a body of work that confronted and validated suppressed spiritual experiences. I credit Our Lady Virgin of Guadalupe for my resurrection from ignoring my creative gift and bringing me home.

Desire for limelight, stability, and fulfilling the gallery-going public’s desire overshadowed numerous invitations and opportunities to explore spirituality. A fruitful lifestyle suppressed the nuance of spirituality never expressed until the silence vanished. My mother’s passing, a spiritual epiphany unraveled memories giving expression to these experiences. The vicious cycle of gallery going public’s desire for my art crumbled the day I returned to my homeland. Time has …

Open For Learning: The Cms And The Open Learning Network, Jon Mott, David Wiley

Faculty Publications

The course management system (CMS) reinforces the status quo and hinders substantial teaching and learning innovation in higher education. It does so by imposing artificial time limits on learner access to course content and other learners, privileging the role of the instructor at the expense of the learner, and limiting the power of the network effect in the learning process. The open learning network (OLN)—a hybrid of the CMS and the personal learning environment (PLE)—is proposed as an alternative learning technology environment with the potential to leverage the affordances of the Web to dramatically improve learning.

Vhf-Uhf Passive Filter Synthesis Based On Acoustic Resonator Structures, Melissa Sefton Dempsey

Theses

This thesis presents a novel design method for approximating standard bandpass filter transfer functions using surface acoustic wave (SAW) technology. This method is based on standard circuit simulation and optimization tools to generate physical specifications for the fabrication of a SAW impedance element filter (IEF) network. The IEF topology is verified in the design of a narrowband bandpass filter composed of commercial quartz SAW resonators. The utility of the design method is further demonstrated for a wider bandwidth filter based on custom resonators fabricated on a lithium niobate substrate. An optimum fit was obtained between the standard filter target response …

Design, Simulation, And Fabrication Of A Flow Sensor For An Implantable Micropump, Matthew J. Waldron

Theses

The design, simulation, and fabrication of a flow sensor to be integrated into an implantable micropump is presented. The flow sensor operates by the method of thermal anemometry, in which heat is dissipated from a resistive element held in the flow of the fluid. The rate at which heat is carried away is dependent on the flow rate and is directly related to the thermal conductance. A control circuit utilizing the constant-temperature anemometry mode of operation is used to generate a change in voltage in response to change in thermal conductance, and subsequently, flow rate. A mathematical expression describing the …

The Cartography Of National Humiliation And The Emergence Of China’S Geobody, William A. Callahan

Research Collection School of Social Sciences

Maps are an important site of the production and consumption of the national image. This essay examines modern Chinese maps to show how the very material borders between foreign and domestic space are the outgrowth of the symbolic workings of historical geography and the conventions of Chinese cartography. These maps do much more than celebrate the extent of Chinese sovereignty; they also mourn the loss of national territories through a cartography of national humiliation. The goal of this essay is to shift our attention from the diplomatic issues of international borders to examine what Chinese maps of China can tell …

A Performance Project With An Historical And Analytical Perspective On The Concerto For Alto Saxophone And Orchestra, Op. 31 By Peter Jona Korn, Brian Sanford Ransom

Dissertations

Peter Jona Korn (1922-1998) is not a name immediately recognized in American music circles, yet during the 1940s and '50s he led a successful career as an American composer. His Saxophone Concerto - composed in 1956 for the virtuoso Sigurd Rascher, and revised by Korn in 1982 - is an important contribution to the saxophone repertoire.

Many composers, including Glazounov, Ibert, and Larsson, wrote concertos for Sigurd Rascher. These works, once considered highly virtuosic, are now studied and performed by college level saxophonists. The original version of Korn's Concerto, among the most technically demanding works, has remained in obscurity for …

Subsidiary Perspective Of Coordination Mechanisms On Localization Decisions, Working Environment, Marketing Engagement And New Product Performance, Firmanzah Firmanzah

Makara Human Behavior Studies in Asia

New product launching (NPL) to the local market by subsidiary managers is a strategic activity, which requires organizational supports from MNC global network. The NPL activity is marked by high level of uncertainty, risk, and market failure. Thus, a headquarter needs to integrate the subsidiary NPL into the global strategy. At the same time, subsidiary managers need to have a certain level of autonomy to ensure that the launching program is adapted to the local specificities. These two pressures have forced the subsidiary managers to take up the roles of ‘boundary spanners’. Good working environment between subsidiaries’ managers and headquarter …

Health Impacts Of Traffic Related Air Pollution, Amit U. Raysoni, Wen-Wahi Li

School of Earth, Environmental, & Marine Sciences Faculty Publications

Ambient air pollution can be a serious cause of concern for any community. Anthropogenic ambient air pollutants can emanate from industries, traffic, geological sources and domestic heating and cooking. However, studies have shown that traffic related air pollution can have far more detrimental health effects than non-combustion sources. These adverse health effects are most profound in sensitive populations like the elderly and young children. The World Health Organization (WHO) attributes more than 300 million deaths every year to ambient air pollution. The WHO’s Air Quality Guidelines (AQG) and the United States Environment Protection Agency’s (USEPA) National Ambient Air Quality Standards …

A Study Of Current Practice Of Corporate Social Responsibility (Csr) And An Examination Of The Relationship Between Csr And Financial Performance Using Structural Equation Modelling (Sem), Lorraine Sweeney

Doctoral

There has been a significant increase in interest in CSR in recent years (Gulyas, 2009; McGehee et al, 2009) and it is regarded as an important topic for research (Burton and Goldsby, 2009). Not only has this topic received academic attention but it is becoming a mainstream issue for many organisations (Renneboog et al, 2008; Nijof and Brujin, 2008). However, it has been noted that research on CSR in SMEs is quite scant (Burton and Goldsby, 2008; Cilberti et al, 2008). A second area of literature that remains unresolved is the relationship between CSR and financial performance (Park and Lee, …

Findings show no indication that the Internet has affected leisure reading rates, that the …

Electro-Osmotic Actuation For Micropump Applications, Sean O'Brien

Theses

An electro-osmotic actuation mechanism is explored for micropump applications where self contained, low power, miniaturized pumps are necessary. The principle of electro-osmosis through a cation selective membrane is used to develop a differential pressure which is used to deflect a pump membrane. In an electro-osmotic cell, there are electrolyte filled chambers on either side of an ion specific membrane. Hydrated cations migrate in an applied electric field, effectively pulling water molecules to the cathodic chamber. In such a setup, the polarity of the current can be periodically reversed causing the chambers to alternately fill and discharge. Since the chemical reactions …
