The Experience of Micro and Macro Events: A Life-Span Analysis

This study investigated how individuals retrospectively construe their lives in terms of major life events. Ninety-nine participants sorted a set of personal and historical events in terms of perceived importance for their lives. Analyses of variance with repeated measures and rank comparisons were computed. Overall findings revealed no cohort differences with regard to the perception of life events. However, within-cohort differences were found, indicating that more life events were recalled from the young adult years. Those experiences were also perceived as having been more important in the participants' lives than events from other age segments. With regard to historical events, war-related experiences were among the highest ranked. Analyses of variance revealed intracohort differences but not intercohort differences, indicating higher scores for the time between 1930 and 1948 relative to other historical periods.

Barriers to front propagation in ordered and disordered vortex flows

We present experiments on reactive front propagation in a two-dimensional (2D) vortex chain flow (both time-independent and time-periodic) and a 2D spatially disordered (time-independent) vortex-dominated flow. The flows are generated using magnetohydrodynamic forcing techniques, and the fronts are produced using the excitable, ferroin-catalyzed Belousov-Zhabotinsky chemical reaction. In both of these flows, front propagation is dominated by the presence of burning invariant manifolds (BIMs) that act as barriers, similar to invariant manifolds that dominate the transport of passive impurities. Convergence of the fronts onto these BIMs is shown experimentally for all of the flows studied. The BIMs are also shown to collapse onto the invariant manifolds for passive transport in the limit of large flow velocities. For the disordered flow, the measured BIMs are compared to those predicted using a measured velocity field and a three-dimensional set of ordinary differential equations that describe the dynamics of front propagation in advection-reaction-diffusion systems.

The Body of Margaret Atwood: Sex Work and Prostitution within Margaret Atwood's The Handmaid's Tale, Oryx and Crake, and The Year of the Flood

In this paper, I will argue that Canadian author Margaret Atwood uses fiscal and socially conservative dystopias to show how sex work and prostitution are choices that women would never have to make in a world with true gender equality. In these radically different worlds, women have no agency beyond their sexuality and no ability to express themselves as equals within either society. And while the structures of both societies, the society of The Handmaid’s Tale and that of both Oryx and Crake and The Year of the Flood, are inherently different, they both stem from modern conservative philosophies: for example, the country of Gilead in The Handmaid’s Tale holds Christian conservative beliefs on the role of religion in the state and the culturally designated roles of women. I define social conservatism as the idea that government organizations are used to pursue an agenda promoting traditional religious values such as “public morality” and opposing “immoralities” such as abortion, prostitution, and homosexuality. I define fiscal conservatism as an agenda promoting privatization of the market, deregulation and lower taxes. In this paper I argue that because these philosophies are incompatible with gender equality, they drive women to occupations such as sex work. Women find that they have no choices and sex work provides something to “trade.” For Offred, this “trading” is more limited, because she is a sex slave. For Oryx, this trading allows her to travel to the West, yet not before her childhood is marked by prostitution and pornography. Sex work allows for Ren to reclaim some agency over her life, yet she only chooses sex work because she is presented with few other options. All of these issues stem from the philosophies that define these dystopias.

Hoisting C Structures Into Clay In Device Drivers

This project addresses the unreliability of operating system code, in particular in device drivers. Device driver software is the interface between the operating system and the device's hardware. Device drivers are written in low level code, making them difficult to understand. Almost all device drivers are written in the programming language C which allows for direct manipulation of memory. Due to the complexity of manual movement of data, most mistakes in operating systems occur in device driver code. The programming language Clay can be used to check device driver code at compile-time. Clay does most of its error checking statically to minimize the overhead of run-time checks in order to stay competitive with C's performance time. The Clay compiler can detect a lot more types of errors than the C compiler like buffer overflows, kernel stack overflows, NULL pointer uses, freed memory uses, and aliasing errors. Clay code that successfully compiles is guaranteed to run without failing on errors that Clay can detect. Even though C is unsafe, currently most device drivers are written in it. Not only are device drivers the part of the operating system most likely to fail, they also are the largest part of the operating system. As rewriting every existing device driver in Clay by hand would be impractical, this thesis is part of a project to automate translation of existing drivers from C to Clay. Although C and Clay both allow low level manipulation of data and fill the same niche for developing low level code, they have different syntax, type systems, and paradigms. This paper explores how C can be translated into Clay. It identifies what part of C device drivers cannot be translated into Clay and what information drivers in Clay will require that C cannot provide. It also explains how these translations will occur by explaining how each C structure is represented in the compiler and how these structures are changed to represent a Clay structure.

Continuous, Passive Liquid-Liquid Extraction and Emulsion Separation Within Microfluidic and Millifluidic Devices

Liquid-liquid extraction (LLE) is a method used to separate compounds based on their relative activity in two immiscible phases. By significantly reducing the scale of liquid-liquid extraction to the micro- and milli-fluidic levels, this separation process can bemade suitable for low volume, high value materials.

Aporias of Trauma in Joyce's Ulysses and Faulkner's Light in August

In this thesis, I explore the relationships between trauma, memory, and narrative, particularly the ways in which trauma simultaneously disrupts and engenders narrative structures. I consider various trauma theories by authors such as Cathy Caruth, Judith Herman, Ruth Leys, and Dominick LaCapra. I also consider how psychoanalytic theory and criticism, specifically the writings of Sigmund Freud, inform the study of traumatic experience from both literary and personal perspectives. Furthermore, I consider theories regarding the relationship between trauma and narrative by authors such as Peter Brooks and John Pilkington. James Joyce¿s Ulysses and William Faulkner¿s Light in August serve, for my purposes, as trauma-texts and reflect the ways in which trauma might complicate the simultaneous destruction and creation of narrative strategies. Reading Ulysses and Light in August as trauma-texts that are both in mourning and melancholic gives us complementary, and contradictory, reasons for why we enjoy them. Mourning constructs a relationship between victim and witness, in which we can hear the voice of trauma and engage it in discourse. Conversely, melancholia creates a relationship between performer and spectator, in which we experience, and are fascinated by, the spectacle of another¿s trauma. Laughter, perversity, sorrow, and respite engage the reader in both texts, and raise questions about how one `remembers-to-forget¿ traumatic experiences. The narratives of each text¿s characters offer unique performances of mourning and melancholia. Thus, while this thesis engenders more questions than answers, I hope to argue that Ulysses and Light in August are significant literary works because each engages the reader in traumatic discourse, entertains the reader with the traumatic spectacle, and enlightens the reader on the complex relationship between trauma and narrative.
