Inaka ga Kokoro ni Fureru: The Practices and Parlance of Cultural Exchange in the Japan-America Grassroots Summit

This thesis is an examination of the John Manjiro-Whitfield Commemorative Center for International Exchange (CIE) and its sole undertaking the annual Japan-America Grassroots Summit. The CIE’s goal is to foster greater mutual understanding between Japanese and American citizens through what it terms grassroots exchange. To achieve this, the CIE aids in organizing a weeklong cultural exchange program held alternately in the United States and Japan complete with a three-night homestay. As a participant-observer in the 25th Annual Grassroots Summit held in Japan, I address the underlying influences shaping this cultural exchange program and limits to achieving its goals. I also address how the summit’s structure and use of historical narratives affects the experiences of Americans who attend the summit when it is held in Japan

The arrival of the ACEs movement in Scotland: Policy entrepreneurship and critical activist responses

This paper combines conceptual and documentary analysis to critique the recent introduction of ACEs (Adverse Childhood Experiences) in Scottish social policy, highlighting the role of the ACE-Aware Nation ‘movement’ and its positioning of the ACEs model through its campaigning activities. Consideration is given to the role of a sophisticated network of policy entrepreneurs and the commercial and political interests at play. Reflection is offered on the critical activist responses to this campaign that seek to highlight the socio-economic and political underpinnings of childhood trauma, which are largely absent in the ACEs model. The argument is that these policy developments amount to a recent turn to the ACEs model as a simplistic solution to complex social problems – a solution that is shown to be ultimately flawed in several respects. This analysis reveals the contradictions, conflicts and confusion that have emerged within the ACEs discourse, caused in the main by heuristic thinking and the conceptual inadequacies, misuses and misunderstandings of the ACEs model. The paper concludes that policy makers and practitioners should exercise caution in their appraisal of the ACEs model and the associated movement in Scotland

Challenging the hero narrative: moving towards reparational citizenship education

In his book, No More Heroes: Grassroots Challenges to the Savior Mentality, Jordan Flaherty claims the saviour mentality exists when “you want to help others but are not open to guidance from those you want to help”. According to Flaherty, the adoption of this mentality results in charitable activities at individual and community levels without broader systemic change, leaving unjust power relations unaddressed. He argues that this mentality is underpinned by racism, colonialism and capitalism, as well as an unethical and historically problematic understanding of charity. With reference to the ongoing partnership work between Scotland and Malawi, this article summarises a conceptual investigation into the possibility that Global Citizenship Education perpetuates the hero narrative. Historical, political and educational research is connected to Bhabha’s theory of cultural hybridity to conceptualise a theory of Reparational Citizenship Education, in contrast to the “reciprocal” approach favoured by policy makers and charitable organisations in Scotland. It is argued that this conceptual shift involves taking the hero narrative to task and that this approach has theoretical and practical implications for the future of Global Citizenship Education

Engineering optical nonlinearities in metal nanoparticle arrays

Thesis (Ph.D.)--Boston UniversityMetal nanostructures supporting localized surface plasmon (LSP) resonances are an emerging technology for sensing, optical switching, radiative engineering, and solar energy harvesting, among other applications. The unique property of LSP resonances that enable these technologies is their ability to localize and enhance the optical field near the surface of metal nanoparticles. However, many questions still remain regarding the effects of nanoparticle coupling on the linear and nonlinear optical properties of these structures. In this thesis, I investigate the role of long-range photonic and near-field plasmonic coupling on the linear and nonlinear optical properties of metal nanoparticles in periodic and deterministic aperiodic arrays within a combined experimental and theoretical framework. In particular, I have developed optical characterization techniques to study various properties of planar metal nano-cylinder arrays fabricated by electron beam lithography (EBL). These include the effect of Fano-type coupling between structural grating modes and LSP resonances on linear diffraction and second harmonic generation (SHG), the influence of near-field coupling on the efficiency of plasmon enhanced metal photoluminescence (PL), the dependence of two-photon PL (TPPL) on nanoparticle size, and the multi-polar nature of SHG from planar plasmonic arrays. Experimental results are fully supported by linear scattering theory of the near and far-field properties of particle arrays based on a range of analytical, semi-analytical, and fully numerical techniques. The breadth of computational methods used allows the investigation of a wide range of structures including large aperiodic arrays with hundreds of discrete particles and periodic arrays with realistic particle shapes, substrates, and excitation conditions. The technological potential of engineered plasmonic structures is demonstrated by enhanced vibrational sum frequency generation (VSFG) spectroscopy, a novel nonlinear sensing technique. These studies have revealed design principles for engineering the interplay of photonic and plasmonic coupling for future linear and nonlinear plasmonic devices for sensing, switching, and modulation. The optical characterization techniques developed in this thesis may additionally be used across a wide range of devices in photonics and nano-optics

The biotechnological potential of whey

peer-reviewedWhey is a highly polluting by-product of cheese and casein powder manufacture with worldwide production of whey estimated at around 190 × 106 ton/year and growing. Historically whey was considered a burdensome, environmentally damaging by-product. In the last decades however, much research has gone into finding viable alternatives for whey rather than just disposing of it. Multiple biotechnological avenues have been explored and in some cases exploited to turn this waste product into a valuable commodity. Avenues explored include traditional uses of whey as both an animal and human food to the more advanced uses such as the use of whey protein as health promoters and the potential of whey to be used as a feed stock to manufacture a whole range of useful substances e.g. ethanol.ACCEPTEDpeer-reviewe

Unmasking the Annexin I Interaction from the Structure of Apo-S100A11

AbstractS100A11 is a homodimeric EF-hand calcium binding protein that undergoes a calcium-induced conformational change and interacts with the phospholipid binding protein annexin I to coordinate membrane association. In this work, the solution structure of apo-S100A11 has been determined by NMR spectroscopy to uncover the details of its calcium-induced structural change. Apo-S100A11 forms a tight globular structure having a near antiparallel orientation of helices III and IV in calcium binding site II. Further, helices I and IV, and I and I′, form a more closed arrangement than observed in other apo-S100 proteins. This helix arrangement in apo-S100A11 partially buries residues in helices I (P3, E11, A15), III (V55, R58, M59), and IV (A86, C87, S90) and the linker (A45, F46), which are required for interaction with annexin I in the calcium-bound state. In apo-S100A11, this results in a “masked” binding surface that prevents annexin I binding but is uncovered upon calcium binding

Laboratory Simulation of the Effect of Rocket Thrust on a Precessing Space Vehicle

Ground tests of solid propellant rocket motors have shown that metal-containing propellants produce various amounts of slag (primarily aluminum oxide) which is trapped in the motor case, causing a loss of specific impulse. Although not yet definitely established, the presence of a liquid pool of slag also may contribute to nutational instabilities that have been observed with certain spin-stabilized, upper-stage vehicles. Because of the rocket's axial acceleration, absent in the ground tests, estimates of in-flight slag mass have been very uncertain. Yet such estimates are needed to determine the magnitude of the control authority of the systems required for eliminating the instability. A test rig with an eccentrically mounted hemispherical bowl was designed and built which incorporates a follower force that properly aligns the thrust vector along the axis of spin. A program that computes the motion of a point mass in the spinning and precessing bowl was written. Using various RPMs, friction factors, and initial starting conditions, plots were generated showing the trace of the point mass around the inside of the fuel tank. The apparatus will incorporate future design features such as a variable nutation angle and a film height measuring instrument. Data obtained on the nutational instability characteristics will be used to determine order of magnitude estimates of control authority needed to minimize the sloshing effect
