    The article of record as published may be found at https://doi.org/10.5129/001041518822704926This article argues that despite the chaos and uncertainty of the post-Soviet period, Russian political outlooks were highly coherent because they were driven by a near consensual desire to achieve greater stability. Based on over-time and cross-section dimensional analyses of a unique dataset of 418 surveys, covering the 1993–2011 period, I show that the popular obsession with restoring order facilitated the consolidation of authoritarianism in Russia. In particular, stability-centric outlooks structured political competition in ways that favored strong-armed incumbent behavior and fostered divisions and extremism among the opposition. These dynamics allowed Russia's increasingly authoritarian regime to rule with minimal use of coercion and largely through the ballot box

    The article of record as published may be found at https://www.washingtonpost.com/politics/2022/01/16/why-would-putin-invade-ukraine/The looming threat of a full-scale Russian attack on Ukraine kept the world on edge for much of 2021, and for good reason — an attack of this magnitude would arguably be the most significant invasion of a European country by a more powerful neighbor since Adolf Hitler’s assault on Poland in 1939. But what purpose would this move serve? As Russia’s preparations and threatening rhetoric have mounted, analysts have pointed out that another invasion of Ukraine would make little sense from a foreign and security policy standpoint

    Extending quality and covariate analyses for gait biometrics

    Recognising humans by the way they walk has attracted a significant interest in recent years due to its potential use in a number of applications such as automated visual surveillance. Technologies utilising gait biometrics have the potential to provide safer society and improve quality of life. However, automated gait recognition is a very challenging research problem and some fundamental issues remain unsolved.At the moment, gait recognition performs well only when samples acquired in similar conditions are matched. An operational automated gait recognition system does not yet exist. The primary aim of the research presented in this thesis is to understand the main challenges associated with deployment of gait recognition and to propose novel solutions to some of the most fundamental issues. There has been lack of understanding of the effect of some subject dependent covariates on gait recognition performance. We have proposed a novel dataset that allows analyses of various covariates in a principled manner. The results of the database evaluation revealed that elapsed time does not affect recognition in the short to medium term, contrary to what other studies have concluded. The analyses show how other factors related to the subject affect recognition performance.Only few gait recognition approaches have been validated in real world conditions. We have collected a new dataset at two realistic locations. Using the database we have shown that there are many environment related factors that can affect performance. The quality of silhouettes has been identified as one of the most important issues for translating gait recognition research to the ‘real-world’. The existing quality algorithms proved insufficient and therefore we extended quality metrics and proposed new ways of improving signature quality and therefore performance. A new fully working automated system has been implemented.Experiments using the system in ‘real-world’ conditions have revealed additional challenges not present when analysing datasets of fixed size. In conclusion, the research has investigated many of the factors that affect current gait recognition algorithms and has presented novel approaches of dealing with some of the most important issues related to translating gait recognition to real-world environments

    The effect of time on gait recognition performance

    Many studies have shown that it is possible to recognize people by the way they walk. However, there are a number of covariate factors that affect recognition performance. The time between capturing the gallery and the probe has been reported to affect recognition the most. To date, no study has shown the isolated effect of time, irrespective of other covariates. Here we present the first principled study that examines the effect of elapsed time on gait recognition. Using empirical evidence we show for the first time that elapsed time does not affect recognition significantly in the short to medium term. By controlling the clothing worn by the subjects and the environment, a Correct Classification Rate (CCR) of 95% has been achieved over 9 months, on a dataset of 2280 gait samples. Our results show that gait can be used as a reliable biometric over time and at a distance. We have created a new multimodal temporal database to enable the research community to investigate various gait and face covariates. We have also investigated the effect of different type of clothes, variations in speed and footwear on the recognition performance. We have demonstrated that clothing drastically affects performance regardless of elapsed time and significantly more than any of the other covariates that we have considered here. The research then suggests a move towards developing appearance invariant recognition algorithms. Thi

    On including quality in applied automatic gait recognition

    Many gait recognition approaches use silhouette data. Imperfections in silhouette extraction have a negative effect on the performance of a gait recognition system. In this paper we extend quality metrics for gait recognition and evaluate new ways of using quality to improve a recognition system. We demonstrate use of quality to improve silhouette data and select gait cycles of best quality. The potential of the new approaches has been demonstrated experimentally on a challenging dataset, showing how recognition capability can be dramatically improved. Our practical study also shows that acquiring samples of adequate quality in arbitrary environments is difficult and that including quality analysis can improve performance markedly

    Prepared for: OPNAV/N514. This research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). NRP Project ID: NPS-23-N068-AThis research examines the evolving strategic partnership between Russia and China as near-peer, nuclear-armed adversaries for the U.S. in the wake of the war in Ukraine. It focuses on Russia’s new security situation after the conflict in Ukraine, particularly how it might attempt to compensate for its depleted strategic capabilities and resources by partnering with China. The research is organized along two parallel tracks. The first track, contained in this part of the technical report, analyzes how Russia’s nuclear posture has evolved as result of the War in Ukraine, and assesses the impact of the Sino-Russian cooperation on Russia’s space program. The second track of this research, contained in Part 2 of the technical report, examines the cooperation between Russia and China in the nuclear realm, as well as its implications. This research was conducted through a combined team effort of subject-matter experts on Russian strategic doctrines, capabilities, and behavior. The researchers performed a rigorous analysis of the debates in the Russian literature, complementing and contextualizing this information through discussions with subject-matter experts in Washington, the U.S. Strategic Command, and the U.S. Space Command.Approved for public release; distribution is unlimited.Naval Postgraduate School, Naval Research Program (PE 0605853N/2098)Naval Postgraduate School, Naval Research Program OPNAV/N51

    NPS NRP Project PosterThis research will examine the implications of the rise of two near-peer, nuclear-armed adversaries for the United States, with an emphasis on the Russian role as a pivotal player in this rising configuration. The focus on Russia will account for the fact that while China's rise makes it potentially the most significant long-term threat, the current scale of Russia's arsenal and its strategic posture make it the most immediate existential threat to the United States and its allies, as well as a key potential spoiler in the U.S. strategic pivot to the Indo-Pacific. The research will proceed along three parallel tracks. The first track will analyze how the different motivations and capabilities of Russia and China to challenge the United States structures their incentives for strategic cooperation, and will review the key debates among Russian elites on these topics. The second part will analyze Russian elite perceptions of the opportunities and limits of cooperation with China in boosting each other's strategic capabilities and their employment strategies. The third track of the research will examine the role of arms control and confidence-building measures in the emerging trilateral context, with the United States facing two near-peer adversaries. This research will be conducted through a combined team effort of subject-matter experts on Russian, U.S., NATO, and Chinese strategic doctrines, capabilities, and behavior. The researchers will perform a rigorous analysis of the debates in the Russian literature, complementing and contextualizing this information through discussions with subject matter experts in Washington, USSTRATCOM, NATO Headquarters, SHAPE Headquarters, and in key European allies. The final report will provide a combined analytical assessment on the topic, and discuss the implications for the USN, DoD, and U.S. national security more broadly.N3/N5 - Plans & StrategyThis research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.
