Description
Belief affects behavior and rhetoric has the potential to bring about action. This paper is a critical content analysis of the ideology and rhetoric of key Islamist intellectuals and the Islamist organization Hizb ut-Tahrir, as stated on the website http://english.hizbuttahrir.org. The responses of specific Muslim Reformers are also analyzed. The central argument underlying this analysis centers on the notion that such Islamist ideology and its rhetorical delivery could be a significant trigger for the use of violence; interacting with, yet existing independently of, other factors that contribute to violent actions. In this case, a significant aspect of any solution to Islamist rhetoric would require that Muslim Reformers present a compelling counter-narrative to political Islam (Islamism), one that has an imperative to reduce the amount of violence in the region. Rhetoric alone cannot solve the many complicated issues in the region but we must begin somewhere and countering the explicit and implicit calls to violence of political Islamist organizations like Hizb ut-Tahrir seems a constructive step.

Description
A good production schedule in a semiconductor back-end facility is critical for the on time delivery of customer orders. Compared to the front-end process that is dominated by re-entrant product flows, the back-end process is linear and therefore more suitable for scheduling. However, the production scheduling of the back-end process is still very difficult due to the wide product mix, large number of parallel machines, product family related setups, machine-product qualification, and weekly demand consisting of thousands of lots. In this research, a novel mixed-integer-linear-programming (MILP) model is proposed for the batch production scheduling of a semiconductor back-end facility. In the MILP formulation, the manufacturing process is modeled as a flexible flow line with bottleneck stages, unrelated parallel machines, product family related sequence-independent setups, and product-machine qualification considerations. However, this MILP formulation is difficult to solve for real size problem instances. In a semiconductor back-end facility, production scheduling usually needs to be done every day while considering updated demand forecast for a medium term planning horizon. Due to the limitation on the solvable size of the MILP model, a deterministic scheduling system (DSS), consisting of an optimizer and a scheduler, is proposed to provide sub-optimal solutions in a short time for real size problem instances. The optimizer generates a tentative production plan. Then the scheduler sequences each lot on each individual machine according to the tentative production plan and scheduling rules. Customized factory rules and additional resource constraints are included in the DSS, such as preventive maintenance schedule, setup crew availability, and carrier limitations. Small problem instances are randomly generated to compare the performances of the MILP model and the deterministic scheduling system. Then experimental design is applied to understand the behavior of the DSS and identify the best configuration of the DSS under different demand scenarios. Product-machine qualification decisions have long-term and significant impact on production scheduling. A robust product-machine qualification matrix is critical for meeting demand when demand quantity or mix varies. In the second part of this research, a stochastic mixed integer programming model is proposed to balance the tradeoff between current machine qualification costs and future backorder costs with uncertain demand. The L-shaped method and acceleration techniques are proposed to solve the stochastic model. Computational results are provided to compare the performance of different solution methods.

Description
This dissertation considers why several characters on the Early Modern Stage choose to remain silent when speech seems warranted. By examining the circumstances and effects of self-silencing on both the character and his/her community, I argue that silencing is an exercise of power that simultaneously subjectifies the silent one and compels the community (textual or theatrical) to ethical self-examination. This argument engages primarily with social philosophers Pierre Bourdieu, Alain Badiou, and Emmanual Levinas, considering their sometimes contradictory ideas about the ontology and representation of the subject and the construction of community. Set alongside the Early Modern plays of William Shakespeare, Ben Jonson and Thomas Kyd, these theories reveal a rich functionality of self-silencing in the contexts of gender relations, aberrant sociality, and ethical crisis. This multi-faceted functionality creates a singular subject, establishes a space for the simultaneous existence of the subject and his/her community, offers an opportunity for empathetic mirroring and/or insight, and thereby leads to social unification. Silence is, in its effects, creative: it engenders empathy and ethical self- and social-reflection.

Description
The discipline of rhetoric and composition established the Writing Program Administrators Outcomes Statement (WPA OS) to fulfill a general expectation about the skills and knowledge students should be able to demonstrate by the end of first-year composition. Regardless of pedagogy used, academic preparation of the teacher, or preference of particular topics or types of assignments, the WPA OS is versatile. This dissertation employs a problem-solution argument showcasing methods to improve assignments through intentional use of the WPA OS for a fluid conversation throughout first-year composition and a more clear articulation of course goals. This dissertation includes summation, analysis, and synthesis of documents that inform first-year composition curriculum from foundational organizations within the field, including National Council of Teachers of English, Council of Writing Program Administrators, National Writing Project, and Conference on College Composition and Communication. This study uses the WPA OS as a lens to examine and revise writing assignments that aid in students' comprehension of the WPA OS with particular focus on the areas of rhetorical knowledge and critical thinking, reading, and writing. Framing assignment design with theoretically grounded content and the use of common topics throughout first-year composition is one way to operationalize the WPA OS. Using common topics throughout course content presents opportunities for teachers to include detailed scaffolding in assignments that expand students' literate practices and engage students as critical thinkers and writers. This study explores how using the topic of family, a common topic to all students, provides a rich bank of social, historical, and cultural elements for research and writing. The topic of family seamlessly employs multimodal composition, which presents students with opportunities for developing rhetorical knowledge and expanding students' literacies. This dissertation displays evidence of praxis of the WPA OS from assignment development to presentation of student samples. This study recommends the use of common topics and intentional application of the WPA OS to construct assignments that clearly articulate learning goals in first-year composition.

Description
Services outsourcing is a prevalent yet problematic phenomenon. On the one hand, more and more firms are outsourcing services function. On the other hand, we are faced with many services outsourcing failures. This research attempts to uncover some of the omitted causes of services outsourcing failure. It extends a conceptual paper that used social network theory to examine the shifting of the triadic relationship structures among the service buyer, service supplier and the buyer's customers at different stages of the services outsourcing arrangements and its performance implications. This study empirically examines these performance implications. Specifically, this research defines the concept of bridge transfer, which denotes the weakening and dissolution of operational ties between the service buyer firms' and their end customers and the appearing and strengthening of operational ties between the service supplier firms and the end customers. It also empirically derives a measurement scale for this new construct. Further, the effects of bridge transfer on supplier's appropriation behavior, buyer's cost of quality and end customers' quality perception are examined in the context of customer facing services and are contrasted with those entail little or no customer interactions. In addition, the moderating roles of buyer-supplier relationship on the effects of bridge transfer are also examined. An Internet-based survey was administered to firms affiliated with CAPS Research and the Institute of Supply Management as the primary data source (n=137). Principal Component Analyses were used to derive a composite score for each of the model construct. Then linear regressions were used to detect the effects of bridge transfer on services outsourcing outcomes and to detect the moderating role of buyer-supplier relationships on these effects. The results show that bridge transfer is positively correlated to suppliers' appropriate behavior and negatively correlated to end customer's quality perception in the context of customer facing services. The effects of bridge transfer are not found for services that entail little or no interactions with the end customers. Instead, buyer-supplier relationship is found to be a key influencing factor to services outsourcing outcomes in this context. This study helps to pinpoint some of the omitted causes of services outsourcing failures and shed light on how to manage services outsourcing for success.

Description
The original mediums were not texts or technologies; they were ritual actors performing acts of mediumship. Mediating between determined norms (the status quo) and emergent trends (change), they invoked divine authority to conjure meanings that proved adaptive, nonadaptive and/or maladaptive. With the advent of the written word, ritual became formalized and codified. The medium became a communication device, something abstract and external to the human condition. It then became possible to speak of "media effects" imposing influence in a logical deterministic manner. Yet with the advent of new media, we are witnessing a return to modes of cultural discourse that are spontaneous, interactive, communal and unscripted, all hallmarks of ritual action. This "ritual return" centers on the emergence of the "prosumer" (producer/consumer), a figure actively engaged in mediating practices. While resembling the original archaic "medium" in some respects, the prosumer is a "literate ritualist" allied with a multiplicity of cultural tribes. Thus the "new media" has given rise to "the new medium." The pages that follow focus on acts of contemporary mediumship, examining related concepts such as "ecology," "niche," "role," "affordance," and "trope." Each section considers how specific mediating practices afford and constrain modes of ritualized behavior. I call this practice-oriented approach to media studies "praxism."

Description
California's Proposition 8 revoked the right to marriage for that state's gay and lesbian population. Proposition 8 was a devastating defeat for gay marriage movements across the nation. The primary rhetorical strategy of the No on 8 campaign was a reliance on a Civil Rights analogy that constructed the gay and lesbian movement for marriage as a civil right akin to those fought for by African Americans in the 1950s and 1960s. Analogizing the gay and lesbian struggle for gay marriage with the racial struggles of the Civil Rights Movement exposed a complicated relationship between communities of color and gay and lesbian communities. This project reads critical rhetoric and intersectionality together to craft a critical intersectional rhetoric to better understand the potentialities and pitfalls of analogizing the gay rights with Civil Rights. I analyze television ads, communiques of No on 8 leadership, as well as state level and national court decisions related to gay marriage to argue alternative frameworks that move away from analogizing and move towards coalition building.

Description
Overcrowding of Emergency Departments (EDs) put the safety of patients at risk. Decision makers implement Ambulance Diversion (AD) as a way to relieve congestion and ensure timely treatment delivery. However, ineffective design of AD policies reduces the accessibility to emergency care and adverse events may arise. The objective of this dissertation is to propose methods to design and analyze effective AD policies that consider performance measures that are related to patient safety. First, a simulation-based methodology is proposed to evaluate the mean performance and variability of single-factor AD policies in a single hospital environment considering the trade-off between average waiting time and percentage of time spent on diversion. Regression equations are proposed to obtain parameters of AD policies that yield desired performance level. The results suggest that policies based on the total number of patients waiting are more consistent and provide a high precision in predicting policy performance. Then, a Markov Decision Process model is proposed to obtain the optimal AD policy assuming that information to start treatment in a neighboring hospital is available. The model is designed to minimize the average tardiness per patient in the long run. Tardiness is defined as the time that patients have to wait beyond a safety time threshold to start receiving treatment. Theoretical and computational analyses show that there exists an optimal policy that is of threshold type, and diversion can be a good alternative to decrease tardiness when ambulance patients cause excessive congestion in the ED. Furthermore, implementation of AD policies in a simulation model that accounts for several relaxations of the assumptions suggests that the model provides consistent policies under multiple scenarios. Finally, a genetic algorithm is combined with simulation to design effective policies for multiple hospitals simultaneously. The model has the objective of minimizing the time that patients spend in non-value added activities, including transportation, waiting and boarding in the ED. Moreover, the AD policies are combined with simple ambulance destination policies to create ambulance flow control mechanisms. Results show that effective ambulance management can significantly reduce the time that patients have to wait to receive appropriate level of care.

Description
A low temperature amorphous oxide thin film transistor (TFT) backplane technology for flexible organic light emitting diode (OLED) displays has been developed to create 4.1-in. diagonal backplanes. The critical steps in the evolution of the backplane process include the qualification and optimization of the low temperature (200 °C) metal oxide process, the stability of the devices under forward and reverse bias stress, the transfer of the process to flexible plastic substrates, and the fabrication of white organic light emitting diode (OLED) displays. Mixed oxide semiconductor thin film transistors (TFTs) on flexible plastic substrates typically suffer from performance and stability issues related to the maximum processing temperature limitation of the polymer. A novel device architecture based upon a dual active layer enables significant improvements in both the performance and stability. Devices are directly fabricated below 200 ºC on a polyethylene naphthalate (PEN) substrate using mixed metal oxides of either zinc indium oxide (ZIO) or indium gallium zinc oxide (IGZO) as the active semiconductor. The dual active layer architecture allows for adjustment in the saturation mobility and threshold voltage stability without the requirement of high temperature annealing, which is not compatible with flexible colorless plastic substrates like PEN. The device performance and stability is strongly dependent upon the composition of the mixed metal oxide; this dependency provides a simple route to improving the threshold voltage stability and drive performance. By switching from a single to a dual active layer, the saturation mobility increases from 1.2 cm2/V-s to 18.0 cm2/V-s, while the rate of the threshold voltage shift decreases by an order of magnitude. This approach could assist in enabling the production of devices on flexible substrates using amorphous oxide semiconductors.

Description
The topos of home is fraught with ideological baggage. This piece works alongside others that labor to rework home as a space for rhetorical topos. I spend the majority of my text analyzing three books from which I explicate the topos of "home." These books are Mike Rose's 1989 work Lives on the Boundary: A Moving Account of the Struggles and Achievements of American's Educational Underclass, Victor Villanueva's 1993 Bootstraps: From and American Academic of Color, and Ellen Cushman's 1998 The Struggle and the Tools: Oral and Literate Strategies in an Inner City Community. I've chosen these books for two interrelated reasons. First, these texts aided in establishing working-class rhetoric as a field of study within the paradigm of rhetoric and composition. And second, in their individual ways, each of these books is anchored in a profound sense of "home." Each of the texts also experiments and resists scholarly conventions to include some autobiographical passages. Central to these passages is the topos of home, a theme that both enriches the author's autobiographical account and informs his or her theory forwarded in that work. These features add fruitful theory building to both the authors' individual texts and the paradigm as a whole. I ground my work in working-class theory, analyzing the work of Steve Parks, Nick Pollard and Nancy Welch, alongside scholarship that analyzes those labeled as "other" in higher-level academia. The stories that Parks, Pollard and Welch quote, the works of Rose, Villanueva, Cushman and even myself, all work toward discussing and creating not only a "home" for working-class academics but also room for more working-class research and theory-building. As I argue in this project, through these very acts of rhetorical/scholarly experimentation, Rose, Villanueva, and Cushman defied conventional standards for what counts as "good scholarship" in order to initiate a scholarly trajectory for working-class rhetoric in the academy. These authors' discussions of the "home" -specifically personal and political references to working-class homes--were instrumental tools in creating a public homeplace and space for further working-class theory building for rhetoricians in our field.
