Closed Time-like Curves and Inertial Frame Dragging: How to Time Travel via Spacetime Rotation

As the number of solutions to the Einstein equations with realistic matter sources that admit closed time-like curves (CTC's) has grown drastically, it has provoked some authors [10] to call for a physical interpretation of these seemingly exotic curves that could possibly allow for causality violations. A first step in drafting a physical interpretation would be to understand how CTC's are created because the recent work of [16] has suggested that, to follow a CTC, observers must counter-rotate with the rotating matter, contrary to the currently accepted explanation that it is due to inertial frame dragging that CTC's are created. The exact link between inertialframe dragging and CTC's is investigated by simulating particle geodesics and the precession of gyroscopes along CTC's and backward in time oriented circular orbits in the van Stockum metric, known to have CTC's that could be traversal, so the van Stockum cylinder could be exploited as a time machine. This study of gyroscopeprecession, in the van Stockum metric, supports the theory that CTC's are produced by inertial frame dragging due to rotating spacetime metrics.

Ogawa Mimei's Children's Stories: A Case Study of the Rise of Childhood in the Context of Westernization and Japanese Modernization

In this thesis, I examine the influences of westernization, the tension between Japanese modernity and tradition, and the stories of Hans Christian Andersen on Ogawa Mimei’s children’s stories. I begin the body of my thesis with a brief historical background of Japan, beginning with the start of the Meiji period in 1868. Within the historical section, I focus on societal and cultural elements and changes that pertain to my thesis. I also include the introduction of Hans Christian Andersen in Japan. I wrap up the historical section by a description of Ogawa’s involvement in the Japanese proletarian literature movement and the rise of the Japanese proletarian children’s literature movement. Then, I launch into an analysis of Ogawa’s works categorized by thematic elements. These elements include westernization, class conflict, nature and civilization, religion and morals, and children and childhood. When relevant, I also compare and contrast Ogawa’s stories with Andersen’s. In the westernization section, I show how some of Ogawa’s stories demonstrate contact between Japan and the West. In the Class Conflict section, I discuss how Ogawa views class through a socialist lens, whereas Andersen does not dispute class distinctions, but encourages his readers to attempt an upward social climb. In the nature and civilization section, I show how Ogawa and Andersen share common opinions on the impact of civilization on nature. In the religion and morals section, I show how Ogawa incorporates religion, including Christianity, into vii his works. Andersen utilizes religion in a more overt manner in order to convey morals to his audience. Both authors address religious topics like the concept of the afterlife. Finally, in children and childhood, I demonstrate how both Ogawa and Andersen treat their child protagonists and use them and their situations to instruct their readers. Through this case study, I show how westernization and the tensions between Japanese modernization and tradition led to the rise of the proletarian children’s literature movement, which is exemplified by Ogawa’s stories. The emergence of the proletarian children’s literature movement is an indication of the establishment of a new concept of childhood in Japan. Writers like Ogawa Mimei attempted to write children’s stories that represented the new Japanese culture that was a result of adapting Western ideals to fit Japanese society. Some of Ogawa’s stories are a direct commentary on his opinion of Japanese interaction with the West. By comparing Ogawa’s and Andersen’s stories, I demonstrate how Ogawa borrows certain Western elements and possibly responds directly to Andersen. Ogawa also addresses some of the same topics as Andersen, yet their reactions are not always the same. What I find in my analysis supports my thesis that Ogawa is able to maintain Japanese tradition while infusing his children’s stories with Western and modern elements. In doing so, he reflects a largely popular social and cultural practice of his time.

Where Stories Collide : Montage and the Short Story Cycle

This thesis uses Sergei Eisenstein’s filmic theories of montage to examine the modernist American short story cycle, a genre of independent short stories that work together to create a larger and interrelated whole. Similar to the shot-by-shot editing process of montage, the story cycle builds its intertextual meaning story-by-story from an aggregate of abrupt narrative transitions and juxtapositions. Eisenstein famously felt that montage, the editing together of film fragments, was not a process of linkage, but of collision –each radically different shot in a film should crash into the next shot, until audience members were intellectually provoked into synthesizing these collisions through dialectical processes. I offer montage as an interpretive strategy for negotiating the narrative collisions in story cycles such as Sherwood Anderson’s Winesburg, Ohio, William Faulkner’s Go Down, Moses, and Eudora Welty’s The Golden Apples. For Go Down, Moses, I argue that Eisenstein’s politically rendered “montage of attractions” provides a template for investigating the shock tactics behind Faulkner’s chronologically and racially entangled stories of whites and African Americans. For The Golden Apples, I consider the opposites and doubles in Welty’s fiction with Eisenstein’s similar belief in the “opposing passions” of the world. Not only, then, do I suggest that the modernist story cycle bears a cinematic influence, but I also offer Eisenstein’s theories of montage and collision as a heuristic for formal, thematic, and even political patterns in a genre infamous for its resistance to definition and classification.

Travel medicine of parasitic diseases in the dog

Companion animals are increasingly brought along by their owners to foreign countries. Thus, small animal travel medicine is becoming more important. The field includes both prophylaxis and metaphylaxis against various infectious diseases, as well as their diagnosis and treatment. Dogs returning from Southern Europe, but also from more tropical regions, may be infected with exotic pathogens. In addition, imported pedigree or working dogs, and especially stray dogs imported through welfare organisations, are at high risk.The present overview summarises the clinical and practical aspects of exotic parasitic diseases that may affect such dogs, and the risk of such diseases becoming autochthonously transmitted in Switzerland. Furthermore, the zoonotic potential of these infections will be considered.

Writing center handbooks and travel guidebooks : redesigning instructional texts for multicultural, multilingual, and multinational contexts

In an increasingly interconnected world characterized by the accelerating interplay of cultural, linguistic, and national difference, the ability to negotiate that difference in an equitable and ethical manner is a crucial skill for both individuals and larger social groups. This dissertation, Writing Center Handbooks and Travel Guidebooks: Redesigning Instructional Texts for Multicultural, Multilingual, and Multinational Contexts, considers how instructional texts that ostensibly support the negotiation of difference (i.e., accepting and learning from difference) actually promote the management of difference (i.e., rejecting, assimilating, and erasing difference). As a corrective to this focus on managing difference, chapter two constructs a theoretical framework that facilitates the redesign of handbooks, guidebooks, and similar instructional texts. This framework centers on reflexive design practices and is informed by literacy theory (Gee; New London Group; Street), social learning theory (Wenger), globalization theory (Nederveen Pieterse), and composition theory (Canagarajah; Horner and Trimbur; Lu; Matsuda; Pratt). By implementing reflexive design practices in the redesign of instructional texts, this dissertation argues that instructional texts can promote the negotiation of difference and a multicultural/multilingual sensibility that accounts for twenty-first century linguistic and cultural realities. Informed by the theoretical framework of chapter two, chapters three and four conduct a rhetorical analysis of two forms of instructional text that are representative of the larger genre: writing center coach handbooks and travel guidebooks to Hong Kong. This rhetorical analysis reveals how both forms of text employ rhetorical strategies that uphold dominant monolingual and monocultural assumptions. Alternative rhetorical strategies are then proposed that can be used to redesign these two forms of instructional texts in a manner that aligns with multicultural and multilingual assumptions. These chapters draw on the work of scholars in Writing Center Studies (Boquet and Lerner; Carino; DiPardo; Grimm; North; Severino) and Technical Communication (Barton and Barton; Dilger; Johnson; Kimball; Slack), respectively. Chapter five explores how the redesign of coach handbooks and travel guidebooks proposed in this dissertation can be conceptualized as a political act. Ultimately, this dissertation argues that instructional texts are powerful heuristic tools that can enact social change if they are redesigned to foster the negotiation of difference and to promote multicultural/multilingual world views.
