Quasi-Elastic d(p⃗,n⃗)2pd(\vec{p},\vec{n})2p Reaction and Spin Response Functions of the Deuteron

We calculated response functions of the deuteron for charge exchange processes, including the final state interaction between two protons. Using them we evaluated the double differential cross section and polarization observables of $d(\vec{p},\vec{n})2p$ by means of plane wave impulse approximation with an optimal factorization. Calculation well reproduced the shape of the energy spectra of the cross section, though somewhat overestimated the magnitude. It also reproduced the spin observables well.Comment: 19 pages of LaTeX (4 figures not included, hard copy available upon request), UT-Komaba 93-2

Engineering Problem Solving And Sustained Learning: A Mixed Methods Study To Explore The Dynamics Of Engineering Knowledge Creation

This dissertation research explores processes by which engineering problem solving (EPS) results in sustained organizational learning. Approaching from a constructionist perspective, the study empirically examines the knowledge creation dynamics instigated by product-related problems using a mixed methods research approach. The research has identified the Japanese concept of ba, defined in this study as shared experiential space, as a key construct that explains the phenomena of interest. A new framework that the study has developed, which interprets EPS as an epistemic journey to attain system-wide improvements, is highly complementary to the traditional structured routine based approaches to engineering operations and management. Operational sustainability is an important issue for every enterprise\u27s survival, to which engineering contributes by managing product and customer requirements. Effective product management is made possible by seamless feedback of lessons learned, which are generated by problem solving. While the literature offers ample evidence of the relationship between problem solving and organizational improvements, however, how this linkage is actually facilitated is not well understood. Studies in industrial engineering and operations research have traditionally emphasized measurable outcomes and the rational aspects of technical problem solving but have yet to saturate the research landscape with more qualitative exploration of the actual processes that leverage engineering knowledge embedded in local contexts. Motivated by the gaps in research, a two-stage empirical study was conducted to probe deeply into the black box of engineering knowledge creation. The study used the exploratory sequential mixed methods research approach to uncover potentially relevant factors for EPS efforts to attain sustained learning, which was defined and subsequently operationalized as positive system changes. In the first phase, a qualitative investigation using grounded theory helped to develop a conceptual model of EPS dynamics. In the second and last phase, this model was tested quantitatively using partial least squares analysis to assess the extent to which the theorized concept can be generalized across a larger engineering sample. The study findings show that contextual factors alone are not sufficient for EPS efforts to result in sustained learning. While these factors have direct effects on operational efficiency and partially affect the effectiveness of problem correction, the EPS processes do not accomplish system changes without first carrying out knowledge creation routines. These routines are a form of sensemaking posited as necessary for cognitive convergence and achievement of a unified interpretation. To the best of our knowledge, this study is first to quantitatively model the concept of ba as a deliberately created environment that promotes such routines, as well as to apply it in a U.S. engineering context. A set of recommendations for engineering knowledge management are provided for practice. For theory, the outcomes of this research illuminate the little addressed link that connects EPS to organizational learning and by so doing contribute to a more complete epistemology of engineering practices

Die individuelle Selbsterschaffung der geschichtlichen Welt und der Staat: “Staat” und “Volk” in der Philosophie Nishida Kitarōs

Originally published as「歴史的世界の個性的な自己創造と国家：西田哲学における〈国家〉と〈民族〉」, in「西田哲学会年報第七号」[ Jahrbuch der Nishida-Gesellschaft] 7 : 55–76. Übersetzt von Leon Krings. In diesem Aufsatz wird der Frage nachgegangen, in welcher Weise der „Staat“ im späten Denken des Philosophen Nishida Kitarō thematisiert wird. Dies geschieht anhand der Staatstheorie Nishidas, wie sie sich in seinen Aufsätzen Das Problem der Staatsraison und Das Problem der japanischen Kultur sowie im Anhang zur Philosophischen Aufsatzsammlung iv darstellt. Zusätzlich werden Nishidas Schriften, die nach den Grundproblemen der Philosophie geschrieben wurden und den theoretischen Hintergrund seiner Staatstheorie bilden, miteinbezogen. In diesen Schriften fragt Nishida – ausgehend von der genetischen Struktur der historischen Wirklichkeit – nach der Daseinsberechtigung sowie der Bedeutung des Staates, d. h. danach, was ein Staat ist und welche Art von Gemeinschaft es verdient, als „Staat“ bezeichnet zu werden. Mithilfe des im Folgenden dargestellten Leitfadens werde ich versuchen, Nishidas Gedankengang genauer nachzuverfolgen. Dabei wird sich zeigen, dass er den „Staat“ als eine im höchsten Maße paradoxe Form der Gemeinschaft interpretiert
