Item Open Access Negotiating Ocean Territory in Bermuda and the Sargasso Sea(2017) Acton, Leslie DianeTo address growing concerns about global oceans health, state and non-state actors have pushed for the establishment of large marine protected areas (LMPAs) in national exclusive economic zones (EEZs) and on the high seas. This push has resulted in a rapid proliferation of LPMAs in recent years, despite limited understanding of their social and political attributes and implications. This dissertation contributes to growing social science scholarship on LMPAs by employing a qualitative, multi-sited case study investigating negotiations over two proposed, overlapping LMPAs in Bermuda’s EEZ and the Sargasso Sea. It engages with human geography theory on territoriality to examine the territorial practices emerging through LMPA proposals and how negotiations over these ‘scaled-up’ management tools are contributing to transformations in global oceans governance. Specifically, it addresses three research questions: (1) What territorial practices do actors use in negotiations over LMPAs? (2) How do these territorial practices produce ocean space? (3) What do these territorial practices reveal about these ocean spaces and human-ocean relations?
To answer these questions, this dissertation traces negotiations over these two proposed LMPAs across space, actors, jurisdictional scale, and time, to study sites including Bermuda, Washington, DC, London, and the 2014 World Parks Congress in Sydney, Australia. Results demonstrate that actors used diverse territorial practices, such as map-making and the promotion of territorial narratives, to negotiate for particular governance outcomes. Some of these territorial practices served to ‘fix’ ocean spaces, belying their continuously emergent material and social realities. Others contributed to altering ocean space despite the absence of any formal regulatory change. Further, analysis revealed that the territorial practices employed during these two distinct, but related LMPA negotiations interacted, producing an unexpected territorial outcome in the Sargasso Sea.
Overall, this dissertation contributes to increasing scholarship in human geography on the emerging territorial processes transforming global oceans governance and, more broadly, human relations with offshore ocean spaces. It presents an empirical study that advances understanding of LMPA negotiations and reveals more diverse interests in and relations to these offshore spaces than traditional conceptualizations suggest. Results from this dissertation could inform ongoing and future LMPA proposals and negotiations through attention to the limits/possibilities produced and revealed by actors’ territorial practices.
Item Open Access Sounds of senescence: Male swamp sparrows respond less aggressively to the songs of older individuals(Behavioral Ecology, 2021-01-01) Zipple, MN; Peters, S; Searcy, WA; Nowicki, SAge-related changes in assessment signals occur in a diverse array of animals, including humans. Age-related decline in vocal quality in humans is known to affect perceived attractiveness by potential mates and voters, but whether such changes have functional implications for nonhuman animals is poorly understood. Most studies of age-related change in animal signals focus on increases in signal quality that occur soon after the age of first breeding (“delayed maturation”), but a few have shown that signal quality declines in older individuals after a mid-life peak (“behavioral senescence”). Whether other individuals are able to detect this senescent decline of assessment signals has not previously been tested. Here we use playback experiments to show that wild male swamp sparrows (Melospiza georgiana) respond more aggressively to songs from 2-year-old males as compared with songs from the same males when they are 10 years old. Senescence in signals that, like birdsong, affect reproductive success through intrasexual competition or mate choice may be of evolutionary significance. Lay Summary: Using playback experiments with wild swamp sparrows (Melospiza georgiana), we demonstrate that listeners both detect and respond to age-related declines in vocal quality. Two previous studies have shown that some song characteristics deteriorate with age later in life in songbirds, but to our knowledge this is the first demonstration outside of humans that such deterioration affects receiver response. Discrimination of songs from males of different ages may have evolutionary implications.Item Open Access States' Pursuit of Sovereignty in a Globalized Security Context: Controlling International Human Mobility(2010) Avdan, NazliThe goal of this dissertation is to inquire into how states balance economic motivations and security concerns when pursuing sovereignty at borders. More precisely, the dissertation examines tradeoffs between interdependence sovereignty -control over transborder flows--and Westphalian sovereignty defined as exclusion of external actors from states' authoritative space. Focusing on control over cross-border human mobility as the issue area, I put forward the securitized interdependence framework as a theory that encompasses economic and security logics of policy-making. Because migration control rests at the nexus of economic/material and geopolitical/military dimensions of state security, it provides an ideal testing ground for observing the interaction of economic and security motives. The theoretical framework draws on the literature on complex interdependence and the logic of the trading state to postulate empirically verifiable propositions on migration control policies.
The central claim of the dissertation is that human mobility is conditionally securitized and that security logics are modulated by material/economic incentives. Facing informational asymmetries vis-à-vis transnational terrorists, states rely on migration and border control strategies to screen and deter non-state threats to security. However, economic interdependence--trade and capital ties--mitigates fears over transnational terrorism by reconfiguring state preferences, bolstering the relative salience of material concerns in policy-making, tempering perceptions of threat, and creating vested interests at the domestic level.
To test the theory I have collected and compiled data on i)visa restrictions for pairs of 207 X 207 directed dyads ii)visa rejection rates for European Union and/or Schengen member countries for the period 2003-2007, and iii)asylum recognition rates for 20 select OECD recipient states for the period 1980-2007. I then use this data to test the implications of the theory by distinguishing between economic/voluntary and political/involuntary migration. Additionally, I tease out the distinct effects of two different types of security concerns over transnational terrorism: a reputational effect that considers origin country citizens' involvement in terrorism incidents worldwide and a targeted/directed impact through which states take into account past experience as targets of terrorism. To illustrate the effect of economic interdependence, I analyze trade and capital flows separately and illustrate that both types of commercial ties facilitate liberalization of controls over human mobility through direct and indirect mechanisms.
I employ a variety of statistical techniques to study the effect of economic and security concerns including several cross-sectional time series techniques, structural break and recursive residual tests for temporal change, and maximum likelihood. Furthermore, I complement my quantitative empirical analysis with an in-depth process tracing approach that traces the evolution of Turkey's migration policies in the context of Turkey's post-1980 economic liberalization. The qualitative analysis makes use of primary and secondary resources obtained from archival field work in Ankara and Istanbul, Turkey.
The dissertation demonstrates that the impact of security concerns over transnational terrorism is contingent on the type of migration policy under consideration. In particular, policies of control over involuntary/political migration are guided by humanitarian and normative motives, limiting the effect of security concerns. Furthermore, the securitization of visa policies is strongest if recipient states are directly targeted by incidents of transnational terrorism perpetrated by origin country nationals. While states take into account incidents of global terrorism ---attacks against other country nationals or territories by origin country citizens-- this channel of impact is more modest. Additionally, empirical results show that economic interdependence effectively undercuts the effect of global terrorism, driving migration control policies towards liberalization. In sum, the dissertation demonstrates that ways in which states assert interdependence sovereignty exhibit temporal and cross-sectional variation as well as functional differentiation across types of border and migration control policies.
