    • "Justified on a scientific basis": Fetal protection policies, sex discrimination, and the selective use of evidence in labor law

      Philips, Susan U.; Feallock, Lynn O'Neill, 1964- (The University of Arizona., 1992)
      As women have increasingly entered what have been traditionally male-dominated industries, there has been a corresponding increase in "fetal protection policies" implemented by those same industries, based on the premise that toxins in the workplace can be harmful to the "potential fetus." The assumption is that these toxins are transported to the fetus exclusively through the mother and that only by removing the mother from the hazardous environment can the fetus be protected. Some of these companies have been taken to court as women have challenged these policies as infringements of their constitutional rights. This paper analyzes court cases in which this issue has been argued and demonstrates how the courts maintain the patriarchal ideologies of both law and industry through the use of legal precedent and unsubstantiated "science," to uphold policies that prohibit women from working in high-paying "male" industries and maintain women's subordinate position in capitalist society.
    • The juvenile court system in Arizona with reference to Pima County

      Hornstra, Theodore Ludwig, 1929- (The University of Arizona., 1957)
    • Juvenile delinquency on the Navajo reservation

      Deloria, Vine, Jr.; Fehr, Angela Birgit, 1964- (The University of Arizona., 1989)
      Three major theories on juvenile delinquency were examined with respect to their applicability to Navajo juvenile crime. The theories selected were social disorganization-social control theory, status frustration-structural strain theory, and normative conflict-differential association theory. An overview of Navajo social organization was given with a focus on traditional methods of deviance control in Navajo society. Additionally, surveys were administered to 111 students at all levels of Chinle High School on the Navajo reservation. Cross-tabulations were used to determine gender differences with respect to the commission of delinquent acts, as well as possible correlations between alcohol abuse in the students' home and liquor offenses committed by students. Religious affiliation, religiosity, as well as selected aspects of acculturation were examined in their relation to Navajo juvenile delinquency.
    • Kaamos Studies

      Alshaibi, Sama R.; Paatos, Karoliina; Shenal, Martina M.; Cerese, Vaden (The University of Arizona., 2018)
      Kaamos Studies is a multi-media thesis project that examines the experience of the darkness that falls with the polar night (kaamos in Finnish) when the sun does not rise and the adaptation to it. In the darkness, there is still an array of different kinds of lights. My focal point is the Kevo Subarctic Research Station at the northernmost tip of Finland where my parents were working as weather attendants from 1976 until 1982. They observed and measured the earth and space weather by multiple devices every three hours, every day and night. I was born there. To create the exhibition installation of Kaamos Studies I have used some of the same devices my parent did, collected material from different kinds of archives and collaborated with weather researchers and institutes in Finland. The exhibition installation consists of four light sculptures of various scale, three videos, one sunshine recorder and The Pocket Book, a handmade artist’s book. This is the written documentation of my thesis exhibition Kaamos Studies for the University of Arizona, School of Art’s Master of Fine Art’s degree.

    • Kangaroo Rat Foraging In Proximity to a Colony of Reintroduced Black-Tailed Prairie Dogs

      Koprowski, John L.; Fulgham, Kirsten Marie; Archer, Steven R.; Elfring, Lisa K. (The University of Arizona., 2015)
      A majority of the arid grasslands in the western U.S. have been dramatically altered by anthropogenic influences resulting in degradation and desertification. Within the arid grasslands of North America a guild of burrowing herbivorous rodents that includes kangaroo rats (Dipodomys spp.) and prairie dogs (Cynomys spp.) is often considered integral to arid grassland maintenance. As part of the larger guild of burrowing herbivorous rodents, kangaroo rats are considered to be an important keystone guild whose role as ecosystem engineers and habitat modifiers complements that of prairie dogs. Together these species organize and structure arid grassland ecosystems and the biodiversity therein, by providing a mosaic of microhabitat patches, thus increasing overall heterogeneity. In an area where black-tailed prairie dogs (C. ludovicianus) were reintroduced, I used Giving-up Density (GUD) to assess the indirect effects black-tailed prairie dogs might have on the foraging patterns of resident kangaroo rats (D. spectabilis and D. merriamii). My objective was to compare and contrast kangaroo rat foraging GUD within and along the boundary of a on a recently established black-tailed prairie dog colony with that in the surrounding unmodified native habitat. This enabled assessment of whether black-tailed prairie dogs had an influence on the perceived quality of the habitat by kangaroo rats. Kangaroo rats visited off-colony feeding trays more frequently, and collected a greater mean mass of seed per tray as well. This indicates that the kangaroo rats perceived the area off the prairie dog colony as having a lower foraging cost than on the colony or along the colony edge. I conclude that from the perspective of the seed-eating kangaroo rat, the colony is not viewed as high quality habitat. What impact the reintroduction and management of one keystone species might have on another keystone species deserves additional consideration as we attempt to restore arid grassland ecosystems.

    • Kenneth Burke's approach to language and theory construction

      Ewbank, Henry L.; Archias, Susan Dana, 1953- (The University of Arizona., 1988)
      This thesis explains the "systematic" refinement of Kenneth Burke's theoretical process through his development of a theological paradigm for the dramatistic vocabulary. It describes the merging metaphysical and dialectical issues in Burke's critical thought and locates a theoretical shift in A Grammar of Motives, where Burke posits the prototype for his key term, "act." The study then interprets the formal treatment of the prototype in The Rhetoric of Religion: Studies in Logology, and demonstrates how the derived paradigm maintains and advances the convergence of metaphysics and dialectics, and how it reestablishes the interaction between language structure and usage in two types of definition or explanation (temporal-logical, narrative-tautological). This thesis also describes the purpose and functional range of Logology.

      Coretz, Irving, 1921- (The University of Arizona., 1949)
    • Kidneys, Chemicals, and Clinics: A Political Ecology of Health in Rural Central America

      Del Casino, Vincent; Lawlor, Emma J.; Del Casino, Vincent; Banister, Jeffrey; Oglesby, Elizabeth; Pieper Mooney, Jadwiga (The University of Arizona., 2015)
      In 2008, El Salvador registered the world's highest mortality rate from kidney failure, with more than 2500 deaths annually in Central America's smallest country. El Salvador is the ground zero of a new form of Chronic Kidney Disease (CKD) that has become an epidemic among otherwise healthy agricultural workers and rural residents in lowland Central America in the past three decades. While the epidemic is believed to stem from some combination of agro- chemical exposure and/or dehydration, research on the disease remains embroiled in controversy, policy changes few, and medical support for affected individuals challenging. Foucaultian theorizations of 'discursive materiality' provide insights into the ways in which–even as the science remains inconclusive–understandings, discussions, and research on CKD in El Salvador are having material effects on individuals' bodies and health statuses. Based on fieldwork in El Salvador in summer 2014, this thesis uses the lens of Salvadorian CKD to explore the workings of biopower in settings of industrial agricultural production. Focusing on the Bajo Lempa region of El Salvador, in particular, the thesis examines the discourses, materialities, and practices through which CKD has "come to matter" as a medical and political phenomenon in relation to the agriculture through which affected Salvadorians make their living. Thinking through the discursive materialities of CKD alongside the production of spaces of health and agriculture, this thesis provides insights for the growing field of the political ecology of health by investigating the wider socio-political and environmental processes that make CKD management such a challenge in a Central America.
    • Kinematic Analysis and Inverse Dynamics-based Control of Nondeterministic Multibody Systems

      Poursina, Mohammad; Sabet, Sahand; Nikravesh, Parviz E.; Gaylor, David (The University of Arizona., 2016)
      Multibody dynamics plays the key role in the modeling, simulation, design, and control of many engineering problems. In practice, such problems may be encountered with the existence of uncertainty in the system's parameters and/or excitations. As the complexity of these problems in terms of the number of the bodies and kinematic loops (chains) increases, the effect of uncertainty in the system becomes even more significant due to the accumulation of inaccuracies. Therefore, considering uncertainty is inarguably a crucial aspect of performance analysis of a multibody problem. In fact, uncertainty needs to be propagated to the system kinematics and dynamics for the better understanding of the system behavior. This will significantly affect the design and control process of such systems. For this reason, this research presents a detailed investigation on the use of the Polynomial Chaos Expansion (PCE) method for both control and kinematic analysis of nondeterministic multibody systems.
