The Kyoto School and Confucianism: a Confucian reading of the philosophy of history and political thought of Masaaki Kosaka

This dissertation examines the philosophy of Masaaki Kōsaka (1900-1969) from the East Asian perspective of Confucianism, which I believe is the most appropriate moral paradigm for comprehending his political speculations. Although largely neglected in post-war scholarship, Kōsaka was a prominent member of the Kyoto School during the 1930s and 40s. This was a group of Japanese thinkers strongly associated with the philosophies of Kitarō Nishida and Hajime Tanabe. Kōsaka is now best known for his participation in the three Chūō Kōron symposia held in 1941 and 1942. These meetings have been routinely denounced by liberal historians due to the participants’ support for the Pacific War and the Co-Prosperity Sphere. However, many of these liberal portrayals have failed to take into account the full extent of the group’s resistance to the military junta of Hideki Tōjō. Adopting the methods and techniques of the empirical disciplines of academic history and Orientalism, I develop an interpretative framework that is more receptive to the political values that mattered to Kōsaka as a Confucian inspired intellectual. This has necessitated the rejection of moral history, which typically prioritises modern liberal values brought a priori to the historical record of wartime Japan, as well as recognition of the different ontological foundations that inform the unique political theories of the East Asian intellectual tradition. Reinforced by the prior research of Michel Dalissier and Graham Parkes, as well as my own reading of the Confucian canon, I adopt David Williams’s thesis of ‘Confucian Revolution’ as my principle schema of interpretation. This, I believe, is better able to reconcile Kōsaka’s support for the war with his strong condemnation of the imperialist practices of the Japanese military. Moreover, acknowledging the importance of Confucianism allows us to fully appreciate Kōsaka’s strong affinity for Kant’s practical metaphysics, Hegel’s political philosophy and Ranke’s historiography.

Evanescent field sensing: optical nanofibres, whispering-gallery-mode microspherical and microbubble resonators

In this thesis, the evanescent field sensing techniques of tapered optical nanofibres and microspherical resonators are investigated. This includes evanescent field spectroscopy of a silica nanofibre in a rubidium vapour; thermo-optical tuning of Er:Yb co-doped phosphate glass microspheres; optomechanical properties of microspherical pendulums; and the fabrication and characterisation of borosilicate microbubble resonators. Doppler-broadened and sub-Doppler absorption spectroscopic techniques are performed around the D2 transition (780.24 nm) of rubidium using the evanescent field produced at the waist of a tapered nanofibre with input probe powers as low as 55 nW. Doppler-broadened Zeeman shifts and a preliminary dichroic atomic vapour laser lock (DAVLL) line shape are also observed via the nanofibre waist with an applied magnetic field of 60 G. This device has the potential for laser frequency stabilisation while also studying the effects of atom-surface interactions. A non-invasive thermo-optical tuning technique of Er:Yb co-doped microspheres to specific arbitrary wavelengths is demonstrated particularly to 1294 nm and the 5S1/2F=3 to 5P3/2Fʹ=4 laser cooling transition of 85Rb. Reversible tuning ranges of up to 474 GHz and on resonance cavity timescales on the order of 100 s are reported. This procedure has prospective applications for sensing a variety of atomic or molecular species in a cavity quantum electrodynamics (QED) experiments. The mechanical characteristics of a silica microsphere pendulum with a relatively low spring constant of 10-4 Nm-1 are explored. A novel method of frequency sweeping the motion of the pendulum to determine its natural resonance frequencies while overriding its sensitivity to environmental noise is proposed. An estimated force of 0.25 N is required to actuate the pendulum by a displacement of (1-2) μm. It is suggested that this is of sufficient magnitude to be experienced between two evanescently coupled microspheres (photonic molecule) and enable spatial trapping of the micropendulum. Finally, single-input borosilicate microbubble resonators with diameters <100 μm are fabricated using a CO2 laser. Optical whispering gallery mode spectra are observed via evanescent coupling with a tapered fibre. A red-shift of (4-22) GHz of the resonance modes is detected when the hollow cavity was filled with nano-filtered water. A polarisation conversion effect, with an efficiency of 10%, is observed when the diameter of the coupling tapered fibre waist is varied. This effect is also achieved by simply varying the polarisation of the input light in the tapered fibre where the efficiency is optimised to 92%. Thus, the microbubble device acts as a reversible band-pass to band-stop optical filter for cavity-QED, integrated solid-state and semiconductor circuit applications.

Exploring an agent as an economic insider threat solution

The insider threat is a security problem that is well-known and has a long history, yet it still remains an invisible enemy. Insiders know the security processes and have accesses that allow them to easily cover their tracks. In recent years the idea of monitoring separately for these threats has come into its own. However, the tools currently in use have disadvantages and one of the most effective techniques of human review is costly. This paper explores the development of an intelligent agent that uses already in-place computing material for inference as an inexpensive monitoring tool for insider threats. Design Science Research (DSR) is a methodology used to explore and develop an IT artifact, such as for this intelligent agent research. This methodology allows for a structure that can guide a deep search method for problems that may not be possible to solve or could add to a phenomenological instantiation.
