While much study has been directed toward the post war consequences of "impartial" militarized intervention considerably less attention has been paid to the consequences of intervention when states are biased for or against a specific actor. In fact, interventions fitting the peace-building or transitional assistance model of intervention represent only a small subset of a much larger class of militarized intervention.

Show moreWhile much study has been directed toward the post war consequences of "impartial" militarized intervention considerably less attention has been paid to the consequences of intervention when states are biased for or against a specific actor. In fact, interventions fitting the peace-building or transitional assistance model of intervention represent only a small subset of a much larger class of militarized intervention. I argue that many of the standard assumptions regarding democratization, post war state capacity, and post war political violence adopted from experiences with the peace building models may not hold for this more generalized case. Building on the concepts of Doyle and Sambanis (2000, 2006) I develop a Strategic Heterogeneity Framework which seeks to explain how differences in an intervener's goals and strategies influence outcomes of post war state capacity, domestic stability (non-violence), and democratization. I conceptualize intervention strategy along two dimensions, bias and intensity. Bias indicates whether the external actor (intervener) has a strong preference for or against a domestic actor or in an unbiased case is "impartial" to the relevant belligerents. Intensity refers to the amplitude of the intervener's commitment and degree of intrusion into the politics and society of their target. High intensity strategies are those where the external intervener becomes the predominant political actor. In low intensity strategies the external actor is more an equal or junior partner. The Strategic Heterogeneity Framework anticipates that the bias and intensity sets up certain structural and agent-specific incentives and/or dis-incentives to democratize, build indigenous political capacity, and mitigate post war violence. This study develops and tests hypotheses derived from Strategic Heterogeneity Framework. As there is already a large qualitative and growing quantitative literature on unbiased peace operations, I chose to focus my empirical effort on the understudied biased dimension of militarized intervention. I identify two categories of biased intervention strategy: intervention partnerships and intervention patronage. Partnerships represent the low intensity variant where external actors facilitate but allow or require their targeted partner to remain the dominant political actor. In a patronistic intervention the external actor is predominant and the supported target is essentially a proxy or client to the external patron. Empirically, I find that patronistic strategies are generally "winning" strategies. External actors who provide the preponderance of military and political capacity tend to achieve their near term political aims; however, winning isn't everything. These same strategies set up perverse incentive structures which tend to create more authoritarian, less capable, and more violent post-war states. Partnership strategies, however, are no more likely to win a war than cases of non-intervention, but conditional on winning, democratization tends to be consistent with the degree of democratization that standard economic and social indicators would predict. The same holds for building state capacity. Partnerships also appear to reduce post war violence relative to cases of non-intervention and patronistic interventions alike.

Show moreDistributed microwave wireless systems have the potential to dramatically reshape wireless technologies due to their ability to provide improvements in robustness, transmit power, antenna gain, spatial and temporal resolutions, size, scalability, secrecy, flexibility, and cost compared to single-platform wireless systems. Traditional wireless systems use a platform-centric model, where improving capabilities generally necessitates hardware retrofitting, which in many cases can result in a bulky, expensive, and inefficient system. Nevertheless, distributed microwave wireless systems require precise coordination to enable cooperative operation. The most highly synchronized systems coordinate at the wavelength level, supporting coherent distributed operations like beamforming. The electric states that need to be synchronized in coherent distributed arrays are mainly the phase, frequency, and time; the synchronization can be accomplished using multiple architectures. All coordination architectures can be grouped under two categories: open loop and closed loop. While closed-loop systems use feedback from the destination, open-loop coherent distributed arrays must synchronize their electrical states by only relying on synchronization signals stemming from within the array rather than depending on feedback signals from the target. Although harder to implement, open-loop coherent arrays enable sensing and other delicate communications applications, where feedback from the target is not possible.In this thesis, I focus on phase alignment and frequency synchronization for open-loop coherent distributed antenna arrays. Once the phase and frequency of all the nodes in the array are synchronized, it is possible to coherently beamform continuous wave signals. When information is modulated on the transmitted continuous waves, time alignment between the nodes is needed. However, time alignment is generally less stringent to implement since its requirements are dependent on the information rate rather than the beamforming frequency, such as for phase and frequency synchronization. Beamforming at 1.5 GHz is demonstrated in this thesis using a two-node open-loop distributed array. For the presented architecture, the phases of the transmitting nodes are aligned using synchronization signals incoming from within the array, without any feedback from the destination. A centralized phase alignment approach is demonstrated, where the secondary node(s) minimize their relative phase offsets to that of the primary node by locating the primary node and estimating the phase shift imparted by the relative motion of the nodes. A high accuracy two-tone waveform is used to track the primary node using a cooperative approach. This waveform is tested with an adaptive architecture to overcome the performance degradation due to weather conditions and to allow high ranging accuracy with minimal spectral footprint. Wireless frequency synchronization is implemented using a centralized approach that allows phase tracking, such that the frequencies of the secondary nodes are locked to that of the primary node. Once the phase and frequency of all the nodes are synchronized, it is possible to coherently beamform in the far field as long as the synchronization is achieved with the desired accuracy. I evaluate the required localization accuracies and frequency synchronization intervals. More importantly, I demonstrate experimentally the first two-node open-loop distributed beamforming at 1.5 GHz with multiple scenarios where the nodes are in relative motion, showing the ability to coherently beamform in a dynamic array where no feedback from the destination is needed.

Currently no drug therapy or vaccine is available for dengue fever, leaving vector control as the major way to protect human populations.

Show moreTransmitted by the bite of mosquitoes, dengue virus (DENV) is the most important arboviral pathogen in humans. Currently no drug therapy or vaccine is available for dengue fever, leaving vector control as the major way to protect human populations. The endosymbiotic bacterium Wolbachia has been proposed as a potential agent for vector control, because it can not only spread within mosquito populations via manipulation of mosquito reproduction but also inhibit transmission of DENV in mosquitoes. In order to develop Wolbachia-based control strategies to prevent DENV infection, we have to better understand the interactions between DENV and Wolbachia in mosquitoes. Aedes albopictus naturally carries Wolbachia infection, however, Wolbachia-mediated viral resistance was not observed in Ae. albopictus. In this study, we demonstrated that the native Wolbachia induce a resistance to DENV in Wolbachia density-dependent manner in Ae. albopictus. A decrease in Wolbachia density within the host cells results in increased dengue infection. We provide evidence that a very low Wolbachia density in mosquito tissues where DENV resides and travels could contribute to the absence of Wolbachia-mediated resistance to DENV in Ae. albopictus. We also investigated the impact of Wolbachia infection on DENV life cycle. We report here that Wolbachia is able to inhibit the intracellular accumulation of DENV in Aedes. aegypti mosquito cells. We showed that Wolbachia infection inhibits DENV binding to mosquito Aag2 cells. We then compared the DENV negative strand RNA levels in Wolbachia infected and uninfected mosquito cells. Wolbachia infection also inhibits DENV replication in mosquito Aag2 cells.To further investigate Wolbachia-DENV interactions in mosquito, we carried out microarray and real-time PCR analyses to define host cell transcriptional responses that are induced by Wolbachia infection. Our data indicates that sixteen previously identified DENV host factors were up-regulated in mosquito cells infected with Wolbachia. An RNA interference (RNAi) screen revealed eleven host factors that are associated with Wolbachia-mediated viral resistance. Our data provides several potential targets for interrupting dengue virus infection in mosquitoes.

Life sentences have increasingly translated into prison stays until the end of natural life. Incarcerated women serving life sentences comprise a small, but growing, sub-population of the prison population. Women with life sentences enter prison with high rates of physical and mental health concerns, and these concerns are often chronic and recurring needs for women’s duration in prison.

Show moreLife sentences have increasingly translated into prison stays until the end of natural life. Incarcerated women serving life sentences comprise a small, but growing, sub-population of the prison population. Women with life sentences enter prison with high rates of physical and mental health concerns, and these concerns are often chronic and recurring needs for women’s duration in prison. Pressing concerns include persistent depression and suicide risk factors. However, there is a lack of research focused on improving this population’s mental health, and specifically, no existing intervention for this population of women. Thus, this dissertation seeks to enhance and broaden the knowledge base about factors that influence the mental health of women with life sentence in order to provide clarity and guide advocacy for prison-based mental health services. Also, this dissertation includes a sub-study that examines the mental health outcomes for a new intervention with this population of women. Two key theories serve as the foundation for this dissertation: importation theory and deprivation theory. Three sub-studies comprise three core chapters of this dissertation. Across these studies, the results highlight implications for social work practice, policy, and research.
