    • Tactical Light Device

      Ellis, Jonathan D.; Esham, Nathan Dean; Koshel, John; Schwiegerling, Jim (The University of Arizona., 2019)
      Less-than-lethal tools are an important selection of equipment for law enforcement officers as it reduces the risk of physical intervention for both the user and the target. While these tools are labeled as less-than-lethal, this classification does not mean that the equipment lacks the ability to cause injury. One such piece of equipment in this category is known as a flashbang. This equipment is explosive-based and as such, comes with the risks that are associated with handling and using explosives. The aim of this thesis is to produce a product that could serve as an alternative to flashbang devices that is based on LEDs rather than explosives. Two prototype devices were manufactured for this thesis for this purpose. The first prototype served as a proof of concept that high-power LEDs could be used to fulfil the requirements set. As a proof of concept, the design of the device was intended to be simple, so the shape of a cube was utilized. Several ideas for the shell of the device were tested with this iteration of the prototype. While the individual parts of the design were simple, assembly of the device proved to be overly difficult and reduced usable interior space. For the second prototype, a greater emphasis was placed on the device of the frame to maximize the manufacturability and functionality. These changes led to a design that was sturdier and easier to assembly than the first prototype. The number of LEDs was greatly increased as well to maximize the visual effect of the device. The second prototype achieved all goals set for the this and serves as a nearly ready example for further testing to before being production ready.

    • Taft and Mexico: neutrality, intervention and recognition, 1910-1913

    • Tailings pond seepage and sulfate equilibrium in the Pima mining district, Pima County, Arizona

      Bassett, R. L.; Artiola, J. F.; Scovill, Georgia Lynn, 1962- (The University of Arizona., 1988)
      Mining activity is suspected of contributing sulfate and total dissolved solids (TDS) to ground water downgradient of the Pima mining district. High ionic concentrations in tailing impoundments suggest that tailings-pond recharge may be a source of the contamination. Experiments indicated that sulfate is not significantly produced by inorganic sulfide oxidation in the tailings ponds. Tailings pond water chemistries were compared with historical water quality analyses in the Pima district. The U.S.G.S. computer program PHREEQE modeled saturation indices for anhydrite, calcite, fluorite, and gypsum in water chemistries throughout the study area. Well water downgradient of the mines had lower saturation indices than tailings pond water which discredits the claim that tailings-pond recharge is acquiring salts as it percolates to the aquifer. Evidence supports the opinion that tailings pond seepage is contributing to the sulfate and TDS content in ground water downgradient of the ponds.
    • Taisho Modan and the Cultural Space of the Taisho Period

      Harrison, Elizabeth G.; Inoue, Kota (The University of Arizona., 1995)
    • Taiwan and the Bush administration's Mainland China policy, January 1989-December 1992

      Schaller, Michael; Wang, Xueliang, 1956- (The University of Arizona., 1993)
      This thesis divides Taiwan's impact on the Bush administration's Mainland China policy into three stages. The first period was from January 1989, when George Bush entered the White House, to June 3, when the Tiananmen Massacre took place in Beijing. The second period was from June 1989 to July 1991. The third period was from July 1991 to the end of 1992. Through examining the Bush administration's Mainland China policy, this thesis argues that Taiwan's impact on the administration's China policy evolved a tract from unimportant to important in the years between 1989 and 1992. It further argues that Taiwan has become an independent factor, whose China policy was not under the control of the United States. Sometimes it undermined American Mainland China policy.
    • Taiwan's economic miracle: Presentations of culture and ideology

      Weaver, Thomas; Harris, Courtney Ann, 1965- (The University of Arizona., 1992)
      Native commentators on Taiwan's recent industrialization consider culture a key factor of the nation's modernization drive. Indigenous writers present Chinese culture as not only economically fit, but also morally superior. Such presentations, I argue, have unspoken ideological goals. Legitimation of the government, paternalistic claims on citizens and workers by the state and employers, and the rhetorical war against communism are some of the tacit agendas I discuss.
    • Taiwanese nurses' knowledge and attitudes toward persons with AIDS

      Longman, Alice J.; Chen, Mei-Yuh, 1963- (The University of Arizona., 1993)
      The purpose of this descriptive study was to describe Taiwanese nurses' knowledge about and attitudes toward persons with AIDS (PWAs). One hundred and two subjects were recruited from three large medical centers in Taiwan during December, 1992 and January, 1993. A backtranslated Chinese version AIDS Vulnerability Survey (AVS) was used to measure Taiwanese nurses' knowledge of AIDS and attitudes toward persons with AIDS. Findings of this study indicated that Taiwanese nurses lack knowledge of AIDS, have negative attitudes toward PWAs, and perceived themselves highly vulnerable to AIDS. A positive relationship was found between attitudes toward PWAs and length of work experience (r = -.28, p ≤ .05). Significant differences were found between marital status and attitudes toward PWAs (t = -2.58, p ≤ .05), indicating that married nurses had more positive attitudes toward PWAs than single nurses.
    • Talker Discrimination in Preschool Children with and without Specific Language Impairment

      Plante, Elena; Dailey, Natalie S.; Alt, Mary; Beeson, Pelagie (The University of Arizona., 2013)
      Variability inherently present between multiple talkers can prove beneficial in the context of learning. However, the performance during learning paradigms by children with specific language impairment (SLI) remains below typically developing peers, even when multiple talkers are used. Preschool children with typically developing language (n = 17) and SLI (n = 17) participated in a talker discrimination task. Five different pairings of talkers (same male, different males, same female, different females, male + female) were used to present 50 spoken words. Children with SLI were significantly poorer in discriminating same and different male speakers compared to their typical peers. The present findings demonstrate that preschool children with SLI can experience difficulty distinguishing between talkers. Poor sensitivity to variation in talkers may contribute to poor learning in SLI for contexts where multiple talker input should benefit the learner.
    • Talking about women and AIDS: Normative discourses on sexuality

      Inhorn, Marcia; Sacks, Valarie Lynne, 1966- (The University of Arizona., 1994)
      A close reading of popular discourses on women and the AIDS epidemic reveals patterns that could be described as attempts to produce and reiterate notions of normative and deviant sexuality. Prostitutes, one frequently depicted "kind" of woman, are presented as indiscriminate, polluting to men, and categorically different from "normal" women. Other women depicted in AIDS discourses are almost always HIV-positive mothers or pregnant women; these women are usually only of concern insofar as they may infect their babies. The themes of self-control, self-discipline, and personal responsibility may also be used to stigmatize women. Such discourses suggest that those who have AIDS are responsible for their own illness. They also deflect attention away from the socioeconomic contexts which may make it more difficult for some to avoid infection, away from the connections between poverty, illness, and disempowerment, and away from the systematic inequalities that characterize U.S. society.
    • The talking circle

      Zapeda, Ofelia; Duffié, Mary Katharine (The University of Arizona., 1989)
      The text and accompanying video tape describe the "talking circle" ritual as it is being used spiritually by a Native American group in Southern Arizona. The text analyzes the evolution of the ritual and applies widely accepted models of group therapy to its uses in the following capacities: Spiritually, (and in) Substance Abuse, Education and the Psychological Treatment of Troubled Teen-agers. The video tape features interviews with local practitioners and is narrated by a traditional Chippewa Indian.
