In the wake of the 2001 anthrax attacks in the US, States Parties to the Biological and Toxin Weapons Convention started to discuss the potential malign application of biological research and technology. This thesis examines how this issue of dual-use has been developed, discussed, and how solutions have been proposed. In order to do so, the thesis follows a neopragmatist approach. As a neopragmatist methodology is largely underdeveloped, the thesis explores some of the key aspects of neopragmatism, specifically its openness to various methods and theories, by directly applying it to the topic. As a result of this approach, the thesis starts with exploratory empirical research, which follows Bruno Latour’s Actor Network Theory. This research reviews how the problem of dual-use has been discussed in three communities: politics and security, ethics, and science. One of the results is that dual-use has primarily been discussed in the security community while the other two were only marginally involved. The proposed solution to the problem by the security community is to place the burden of responsibility on the scientific community. The second part of the thesis then uses theory, Niklas Luhmann’s social systems theory and Martin Heidegger’s work on questioning technology, to critically challenge this solution developed in the security community. The thesis concludes by identifying approaches to help deal with the dual-use issue. It also examines how the adoption of a neopragmatist methodology has influenced and guided the thesis.

Space technologies are becoming increasingly indispensible for modern societies and militaries around the globe, through a heightened dependency on satellite based services. At the same time, anti-satellite weapons are being developed and tested with the capacity to attack and destroy a satellite with precision. In the light of this development, the legal uncertainty on what rules apply to belligerent use of force in the realm of outer space is problematic. Since dual-use satellites do not enjoy explicit special protection in international law, it is relevant to clarify what legal protection they do hold, being objects enabling indispensable societal services. Would state practice and hostile space conduct prevail clarification, a fatal international custom might develop, and the difficulty of reaching agreements regulating attacks on satellites, along with other hostile behavior, enhanced. The purpose of this thesis is to investigate what the current frameworks of space law and international humanitarian law provide in terms of restraints to states’ legal possibilities to attack dual-use satellites in times of armed conflict. It is concluded that both frameworks do hold restrictions respectively. Though, the need for regulation is still evident in order to achieve a clear and foreseeable legal reality along with a sustainable future of space exploration where international peace and security can be maintained.

Dual method use, or the concurrent use of one contraceptive method to prevent pregnancy and another to reduce the risk of sexually transmitted infections (STIs), is an ideal practice for young women but is underutilized. In a recent National Survey of Family Growth (NSFG) study, 7.4% of women of reproductive age reported dual method use at last intercourse. In the same NSFG study, dual method use at last intercourse among women 15-20 years old was somewhat higher at 22.8%; still, this estimate indicates low utilization when compared to recent trends in the prevalence of single-contraceptive method use by young women. Apart from the NSFG and some smaller scale studies, there have been minimal efforts to explore dual method use in high-risk populations of young women such as college students. This is surprising, given that college students typically have more opportunities to be sexually active than other groups and often engage in serial monogamy or have multiple sexual partners during their college years. This study aimed to add to previous research on women’s health and contraception by assessing college women’s contraceptive use, including dual method use, and examining factors that influence contraceptive decision-making. Female students at ETSU were surveyed through the Department of Psychology research participation system from Oct 2017-Dec 2017. Students received class credit for survey completion. Data were analyzed using descriptive statistics in SPSS (Version 24.0). To be consistent with previous studies on health behaviors of college-aged women, the final dataset included only female college students between ages 18 and 25 (n=379). About one-fifth (21.1%) of women reported current dual method use. Of particular interest, only 30.5% of women who indicated sexual activity in the past six months also reported dual method use. Nevertheless, most women reported positive feelings about dual method use and indicated they would not find it hard to achieve dual method use; 69.1% reported feeling great or good about dual method use, and 74.5% indicated that it would not be hard to use condoms plus another form of birth control together correctly. Future efforts to study dual method use in college women should include close examination of subgroups who have yet to commit to dual method use but have positive attitudes and intentions regarding dual method use. Results of this study also indicate a need to implement educational and promotional strategies in college environments to better inform college-aged women about dual method use and its benefits.

The thesis considered the feasibility of space warfare with an emphasis on the malicious potential of dual-use technology. I have described the orbital principles and set the presumptions of space warfare and the principles for space warfare strategy, introduced dual- use technology and its connections to space weapons, elaborated on existing counterspace capabilities and its impact, described the challenges for space warfare and evaluated the utilization of dual-use technology as space weapons. I have reached the conclusion that current space technology does not allow to lead extensive space warfare. However, counterspace technology is mature enough for the conduct of destructive space operations and states are encouraged to proliferate advanced offensive counterspace capabilities that are not sufficiently addressed and bounded to international law. Though, despite it seems space warfare is unlikely, the growing tensions of state space actors and rapid development of new technology that is currently mostly driven by the commercial actors may soon change the situation. Potentially destructive dual-use technology may then increase the risk and probability of space warfare. The thesis proposed several options of potentially destructive dual-technology technology that could be turned into space weapons.

INTRODUCTION: E-cigarettes have emerged as the most commonly used tobacco or nicotine products among youth in the United States (US), and usage with other products (dual use) is not well understood. This study assessed dual use and identified associated factors of usage in school-going youth in the high tobacco burdened region of rural Appalachian Tennessee. METHODS: Two waves of data for the same cohort of students were collected in 2014 (Wave 1) and 2016 (Wave 2). Dual use of e-cigarettes with any other tobacco product was the dependent variable. The independent variables consisted of exposure to tobacco use at home, home smoking rules, smoking inside the vehicle, attitudes toward smoking, exposure to tobacco industry marketing/promotion, and peer/family pressure. Descriptive statistics and multivariate logistic regression analyses were conducted to determine the prevalence of dual use and delineate factors associated with usage. RESULTS: Dual use increased from 13.3% in Wave 1 to 18.6% in Wave 2. Results of logistic regression show that exposure to tobacco industry marketing/promotion was significantly associated with dual use in the two waves, odds ratio (OR) = 4.18 (confidence interval [CI] = 1.69-10.38) and OR = 4.43 (CI = 2.03-9.67), respectively. While allowing smoking inside the vehicles, sometimes, significantly increased dual use in Wave 1 (OR = 3.18 [CI = 1.19-8.48]), exposure to tobacco use at home (OR = 2.94 [1.24-6.97]), and peer/family pressure (OR = 2.92 [1.87-7.19]) increased usage in Wave 2. CONCLUSION: The increasing trend in dual use of e-cigarettes and other tobacco products among youth in Appalachia Tennessee suggests a critical need for comprehensive tobacco control programs to avert exacerbating disparities in tobacco use and tobacco-related diseases in the US.

BACKGROUND: E-cigarette use has grown in popularity, especially as the devices have been touted as smoking cessation tools. In an exploratory study, we sought to compare dual users (i.e., users of both combustible tobacco and e-cigarettes) to e-cigarette only users. METHODS: The Electronic Cigarette Opinion Survey (ECOS) was employed to assess users' (n=78) perceptions and consumption of e-cigarettes and combustible cigarettes. Quantity of e-juice and nicotine used and time of initial nicotine exposure were assessed. Multivariable logistic regression was used to evaluate the association between e-cigarette use behaviors and being an e-cigarette only user compared to a dual user. RESULTS: Compared to dual users, e-cigarette only users consumed higher levels of nicotine in e-juice (p=0.0009) and more nicotine per month (p=0.03). For dual users, the time of first nicotine exposure after waking was significantly earlier than for e-cigarette only users (mean= 9.6 minutes (SD= 8.0) and mean= 26.6 minutes (SD= 22.0), respectively; p=0.0056). Results from the regression models suggest the amount of e-juice consumed and time of first nicotine exposure after waking are significantly associated with being an e-cigarette only user. CONCLUSIONS: These findings shed light on the perceptions and use patterns of e-cigarette only users compared to dual users. As regulation of e-cigarettes is considered, understanding the impact of e-cigarettes and dual use is imperative. Despite frequent marketing claims that e-cigarettes are completely safe, health campaigns need to convey emerging and mixed findings on safety as well as current scientific uncertainty to the public.

Current agroecosystem management practices have a negative effect on natural enemies and their ability to control insect pests. Conservation biological control through the addition of flowering resources can manage food resources for natural enemies. These floral resources can also provide multiple ecosystem services. Study goals were to determine if perennial Thymus vulgaris L. was attractive to natural enemies and if so, could it be a dual use resource encouraging pest management and providing harvestable product. In 2018 plots in three locations were used to examine the effect of habitat throughout the growing season on the attractiveness of T. vulgaris. Large numbers of Thysanoptera and Hemiptera were collected in all locations, represented by phytophagous Aphididae and Thripidae, and predatory Anthocoridae. Location influenced other families to varying degrees. Seasonal specimen counts were influenced by vegetation density, floral phenology, and predator/prey relationships. In 2019 replicated plots of three treatments were used to examine if harvesting plant material affected the attractiveness of T. vulgaris to natural enemies. Total specimens in 2019 were not significantly different among treatments, indicating removal of blooms did not significantly affect the attractiveness of T. vulgaris. Significant numbers of Thysanoptera and Hemiptera were again collected in all treatments, represented by phytophagous Aphididae and Thripidae. Greater numbers of Diptera and Hymenoptera were also collected. Significant numbers of Thripidae, Aphididae, Mymaridae, and Platygastridae were found in the Family level analyses. Results from both years indicate T. vulgaris was attractive to natural enemy and phytophagous Families. Data from 2018 suggest natural enemy families were attracted to alternative prey and hosts utilizing the foliage rather than flowers but the use of nectar and pollen cannot be ruled out. Data from 2019 suggest the presence of flowers played an important role in the attractiveness of T. vulgaris to micro-hymenopteran parasitoids, Syrphidae, and native Apidae. In conclusion, Thymus vulgaris has the potential to be a dual use floral resource that benefits growers through supporting native enemy populations and pollination services, as well as provide income from the harvest of foliage. It could also be used as a beneficial, harvestable floral resource in urban gardens to encourage pollinator conservation and natural pest control.
