Cooperative security in Northeast Asia: ramifications of change in the U.S. and ROK maritime strategies

Since the end of World War II, stability in Northeast Asia has been a key goal of the United States. Maintaining a balance of power in this maritime theater has proven important for regional stability and global economic growth. The modernization of the South Korean Navy and its changing maritime strategy will have ramifications for the U.S.-Republic of Korea (ROK) relationship in the future. In the current world situation, changing regional threats will require new approaches to maintaining future stability. The United States and South Korea must work together toward achieving stronger bilateral and multilateral relationships with other principal actors in the region to achieve this goal. The purpose of this thesis is to review the changing strategies of the United States and South Korean Navies in Northeast Asia and to examine the ramifications should a more cooperative maritime alliance structure be utilized in the future. It is relevant because the United States has played a vital role in the security of the Korean peninsula since the end of World War II, and because decisions made by South Korea regarding security matters affect the United States and its interests in the region.http://archive.org/details/cooperativesecur109454868Lieutenant, United States NavyApproved for public release; distribution is unlimited

Modeling Complex Electrokinetic Nanofluidic Systems

The electrical double layer (EDL) nano-structure at the interface between electrolytes and charged surfaces dominates the performance of a myriad of electrokinetic and electrochemical processes. A complete understanding of the EDL nano-structure allows for a predictive tool for various systems such as supercapacitors, desalination, and nano-particle manipulation. My work involves developing theoretical models to elucidate the nano-structure of the EDL and the consequent effects on fluid flow and species transport in such systems. These include models explaining dispersion of ions in channels with thick EDLs, surface-charge-based ion conductivity changes, nanofluidic-based DNA hybridization, nanofluidic isotachophoresis, charge inversion due to large ions, and nanofluidic systems with heterogeneous surface charges. Collectively, these studies have enriched our understanding of complex electrokinetic nanochannel transport.First, I describe a model for the EDL in nanofluidic channels, showing experimentally validated theoretical regimes where dispersion and/or significant EDL size might affect experimental results, as well as methods to account for these effects. Understanding these effects is essential to accurately interpret experiments as well as design of future experiments and subsequent applications. This model can further explain other micro- and nanoscale electrokinetic transport physics. For example, 1) this theory can explain nanochannel conductivity changes due to changes in surface charge, 2) accounting for reaction terms, it can accurately model non-equilibrium DNA hybridization as well as the effect of nano-confinement on such hybridization in electrokinetic capillary electrophoresis-based systems, 3) it can predict an isotachophoretic-like standing front in nanochannels with surface-charge-inverting complex ionic species that induce fluid flow reversal, and 4) it can describe behavior with heterogeneous surface charge. To explain the behavior of nanofluidic systems with heterogeneous surface charge and complex ionic species, I refined the model by accounting for hard-sphere ion size and more complex near-field screening effects using classical Density Functional Theory. I conducted a theoretical study to explore heterogeneous surface charge in nanochannels with embedded, addressable electrodes that allow us to fully probe EDL structure. I developed a more complete EDL model and performed a systematic theoretical study of EDL nano-structure by varying ion diameter, valence, and concentration, as well as surface charge in order to elucidate EDL nano-structure, fluid flow, and species transport in nanochannels. Thus far we have preliminary model validation using custom-fabricated nanochannels with complex ions, and further experiments will both interpret nanochannel physics through theory as well as improve the model via experimental feedback, overall enabling a more complete predictive theory for future experimental and application design

Listen up! Listening skills in accounting education : gaps and proposed new research and teaching agendas

Utilising a systematic literature review, this paper synthesises alternative theoretical perspectives on listening and studies of accounting students’ listening skills. It identifies gaps in the conceptualisation of listening within accounting education research. Research and teaching agendas are then developed which provide a framework for more effectively fostering the development of listening skills in accounting education. We identify the need for research and teaching around: why listening matters; the elements of effective listening; and developing listening skills. Greater focus on the interpersonal, social, and reflexive aspects of listening is needed, going beyond an existing focus on comprehension and information acquisition. There is also a need to explicitly address the role and benefits of listening in facilitating an ethical organisational culture, recognising the ethical dimensions of professional responsibility and active listening as part of empathetic leadership

A deleterious RNF43 germline mutation in a severely affected serrated polyposis kindred

We report a germline nonsense mutation within the extracellular domain of the RING finger ubiquitin ligase RNF43, segregating with a severe form of serrated polyposis within a kindred. The finding provides evidence that inherited RNF43 mutations define a familial cancer syndrome.This work was supported by the The Canberra Hospital Private Practice Trust Fund (DT, MC), National Health and Medical Research Council Program Grant 1016953 (CCG and MCC) and NHMRC Australia Fellowship 585490 (CCG, TDA, MF).
