Explaining China\u27s Contradictory Grand Strategy: Why Legitimacy Matters

This dissertation analyzed the internal incoherence of China’s grand strategy. To do so, it used the cultural driver of honor to explain the contradictory behavior of China, which ranges from peaceful, responsible international actor to assertive, revisionist rising power with hegemonic ambitions. The central research question asked why China often diverges from Peaceful Development, thus leading to major contradictions as well as possible misperceptions on the part of other nations. Honor was the standard of reference that was utilized and examined in order to establish congruence and coherence between deed and praxis. Accordingly, the first hypothesis of this study posited that if policy diverges from or is incongruent with China’s standard of national honor, then the grand strategy is internally incoherent. Second, two further hypotheses posited that China will tend to use peaceful means if its goal is to enhance external legitimacy, whereas it will tend to use assertive means if its goal is to enhance internal legitimacy. This dissertation began by broadly tracing the cultural driver of honor and the link between honor and legitimacy in Chinese history. The second part of the dissertation looked at the six most salient events within a six-year timeframe (2009-2015) by way of the focused, comparative single-case-study method. For each grand strategy policy input (military strategy, economic policy, and diplomatic policy), the two most salient events were carefully chosen. A fourth grand strategy input, legitimacy (both internal and external), was evaluated for each of these events as well. Methodologically speaking, this study used process tracing in these within-case studies of the single case of China’s grand strategy. Results showed that China’s grand strategy manifestations are by and large legitimacy-driven and that, therefore, peaceful or assertive actions may be differentiated in terms of relation to external or internal legitimacy. In sum, this dissertation advanced an innovative means of inquiry into the grand strategy of a non-Western country, contributed valuable information for the policy community, and offered results that enable a re-evaluation of the debate on the peaceful or violent rise of China

Broadband spin-controlled focusing via logarithmic-spiral nanoslits of varying width

This work presents analytical, numerical and experimental demonstrations of light diffracted through a logarithmic spiral (LS) nanoslit, which forms a type of switchable and focus-tunable structure. Owing to a strong dependence on the incident photon spin, the proposed LS-nanoslit converges incoming light of opposite handedness (to that of the LS-nanoslit) into a confined subwavelength spot, while it shapes light with similar chirality into a donut-like intensity profile. Benefitting from the varying width of the LS-nanoslit, different incident wavelengths interfere constructively at different positions, i.e., the focal length shifts from 7.5 μm (at λ = 632.8 nm) to 10 μm (at λ = 488 nm), which opens up new opportunities for tuning and spatially separating broadband light at the micrometer scale

Spin-density-wave transition of (TMTSF)2_2PF6_6 at high magnetic fields

The transverse magnetoresistance of the Bechgaard salt (TMTSF)$_2$PF$_6$ has been measured for various pressures, with the field up to 24 T parallel to the lowest conductivity direction c$^{\ast}$. A quadratic behavior is observed in the magnetic field dependence of the spin-density-wave (SDW) transition temperature $T_{\rm {SDW}}$. With increasing pressure, $T_{\rm {SDW}}$ decreases and the coefficient of the quadratic term increases. These results are consistent with the prediction of the mean-field theory based on the nesting of the quasi one-dimensional Fermi surface. Using a mean field theory, $T_{\rm {SDW}}$ for the perfect nesting case is estimated as about 16 K. This means that even at ambient pressure where $T_{\rm {SDW}}$ is 12 K, the SDW phase of (TMTSF)$_2$PF$_6$ is substantially suppressed by the two-dimensionality of the system.Comment: 11pages,6figures(EPS), accepted for publication in PR

Justifications for the Probation Sanction Among Residents of Virginia--Cool or Un-Cool?

Perhaps as evidence of a growing cultural gap between our students and ourselves, one of the authors was recently amused when a student asked whether probation was a cool sanction. In this study, we begin an investigation into how cool the probation sanction is in the eyes of residents of the Commonwealth of Virginia. Specifically, we use data from a telephone survey of 840 registered voters to explore three questions. First, how often would they recommend the probation sanction in comparison to other sanctions? Second, how do they justify the sanction relative to justifications for other sanctions? Finally, are their justifications and sentencing recommendations consistent across crimes? We address these questions in this study to see whether the sanction is cool or uncool. In the review of literature, we discuss punishment justifications in general and probation as a punitive experience

SDW and FISDW transition of (TMTSF)2_2ClO4_4 at high magnetic fields

The magnetic field dependence of the SDW transition in (TMTSF)$_2$ClO$_4$ for various anion cooling rates has been measured, with the field up to 27T parallel to the lowest conductivity direction $c^{\ast}$. For quenched (TMTSF)$_2$ClO$_4$, the SDW transition temperature $T_{\rm {SDW}}$ increases from 4.5K in zero field up to 8.4K at 27T. A quadratic behavior is observed below 18T, followed by a saturation behavior. These results are consistent with the prediction of the mean-field theory. From these behaviors, $T_{\rm {SDW}}$ is estimated as $T_{\rm {SDW_0}}$=13.5K for the perfect nesting case. This indicates that the SDW phase in quenched (TMTSF)$_2$ClO$_4$, where $T_{\rm {SDW}}$ is less than 6K, is strongly suppressed by the two-dimensionality of the system. In the intermediate cooled state in which the SDW phase does not appear in zero field, the transition temperature for the field-induced SDW shows a quadratic behavior above 12T and there is no saturation behavior even at 27T, in contrast to the FISDW phase in the relaxed state. This behavior can probably be attributed to the difference of the dimerized gap due to anion ordering.Comment: 4pages,5figures(EPS), accepted for publication in PR

Field-induced confinement in (TMTSF)2ClO4 under accurately aligned magnetic fields

We present transport measurements along the least conducting c direction of the organic superconductor (TMTSF)2ClO4, performed under an accurately aligned magnetic field in the low temperature regime. The experimental results reveal a two-dimensional confinement of the carriers in the (a,b) planes which is governed by the magnetic field component along the b' direction. This 2-D confinement is accompanied by a metal-insulator transition for the c axis resistivity. These data are supported by a quantum mechanical calculation of the transverse transport taking into account in self consistent treatment the effect of the field on the interplane Green function and on the intraplane scattering time

Response of Temperate, Subtropical and Tropical Soybean Genotypes to Type-B Overflow Tidal Swamp of Indonesia

Twenty-nine soybean genotypes originating from various countries were evaluated on the tidal swamp of Indonesia to obtain information of agronomic character diversity as the soybean response to the environment and to obtain adaptive genotypes that can be used to develop soybean genotypes for the land. This study was conducted in a complete randomized block design with 3 replications. Diverse genetic backgrounds, countries and climatic regions of the 29 soybean genotypes were responsible for the difference in agronomic responses among the genotypes. All temperate and sub-tropical genotypes were able to produce seeds in the tropical type-B overflow tidal swamp. Adaptability based on seed yield resulted in 1 highly adaptive, 17 adaptive, 5 moderately adaptive and 6 non-adaptive genotypes. Adaptive and highly adaptive genotypes produced 1.56 - 2.58 tons ha-1 of seeds. Karasumame (Naihou), a subtropical genotype, produced the highest seed yield which was 65% higher than Indonesia average soybean productivity and 225% higher than soybean productivity with non-saturated soil culture technology on the tidal swamp. This study concluded that temperate and subtropical genotypes could be used as germplasm sources for soybean development in the tropical type-B overflow tidal swamp in Indonesia

Periodic orbit resonances in layered metals in tilted magnetic fields

The frequency dependence of the interlayer conductivity of a layered Fermi liquid in a magnetic field which is tilted away from the normal to the layers is considered. For both quasi-one- and quasi-two-dimensional systems resonances occur when the frequency is a harmonic of the frequency at which the magnetic field causes the electrons to oscillate on the Fermi surface within the layers. The intensity of the different harmonic resonances varies significantly with the direction of the field. The resonances occur for both coherent and weakly incoherent interlayer transport and so their observation does not imply the existence of a three-dimensional Fermi surface.Comment: 4 pages, RevTeX + epsf, 2 figures.
