Tariffs and the Adoption of Clean Technology Under Asymmetric Information

This paper examines the effect of import tariffs on the decision of a foreign monopolist to adopt “clean” technology – technology that reduces the flow of a negative cross-border externality per unit of exports. The clean technology is assumed to increase the marginal cost of production relative to the dirty technology, but only the firm knows the extent of the increase. Under complete information, we show that, despite its protectionist motivation, the importing country’s optimal tariff induces the firm to adopt the clean technology if and only if it is globally efficient to do so. Under incomplete information, this efficiency property is disrupted. If the optimal tariff is decreasing in the marginal cost, then it leads the firm to bias its choice in favor of dirty technology.

Nonlinear Lattices Generated from Harmonic Lattices with Geometric Constraints

Geometrical constraints imposed on higher dimensional harmonic lattices generally lead to nonlinear dynamical lattice models. Helical lattices obtained by such a procedure are shown to be described by sine- plus linear-lattice equations. The interplay between sinusoidal and quadratic potential terms in such models is shown to yield localized nonlinear modes identified as intrinsic resonant modes

Observation of -9 dB quadrature squeezing with improvement of phase stability in homodyne measurement

We observe -9.01$\pm$0.14 dB of squeezing and +15.12$\pm$0.14 dB of antisqueezing with a local oscillator phase locked in homodyne measurement. In reference [1], two main factors are pointed out which degrade the observed squeezing level: phase fluctuation in homodyne measurement and intracavity losses of an optical parametric oscillator for squeezing. We have improved the phase stability of homodyne measurement and have reduced the intracavity losses. We measure pump power dependences of the squeezing and antisqueezing levels, which show good agreement with theoretical calculations taking account of the phase fluctuation.Comment: 4 pages, 4 figure

A Note on Mackinawite (so-called Valleriite) from the Kawayama Mine, Japan

Mackinawite, a new species of copper-free iron sulfide mineral given by EVANS et al. (1964), has been described in connection with its paragenesis with some others. On the basis of its microtextures it is deducible that from the original ore solution four types of solid solutions A (rich in FeS), B (rich in ZnS), C (rich in CuFeS2) and D (including all other sulfide minerals such as FeS2, PbS, etc.) might have been fractionated, and mackinawite is related only to the second type. The thermal effects on the specimens have been scrutinized and the results obtained evidently suggest that the mineral in question is reasonably contained in the system of Cu-Fe-S and gets to be immiscible at certain temperatures (l30°C～200°C) far lower than those shown in the preceding literatures.今村外治教授退官記念特集

Magnetometric and Röntgenometric Studies of Pyrrhotite from the Kawayama Mine, Japan

Pyrrhotites (FeSx), of various compositions, collected chiefly from the Kawayama mine have been subjected to investigation. The value of saturation magnetization (σs) depending on the composition is in the range of 0 ～22 e.m.u./gr. for x=1.066～1. 142. It is deduced from a maximum value of saturation magnetization that Fe3+ ions are present mainly in the B layer and partly in the A layer of the Bertaut type structure. Natural specimens of pyrrhotite are on the basis of the magnetic susceptibility versus temperature (σ-T) relations classified into four types : 1) Type I, with no α- and γ-transformations above the room temperature and very small σ in magnetic susceptibility, 2) Type II, with well defined γ-transformations, 3) Type III, showing γ-transformation superposed on σ-T curve of Weiss type, and 4) Type IV, with σ-T curve of Weiss type. The saturation magnetization and composition range are σs. ≲1 and 1.05 ≲ x ≲ 1. 09 for Type I,1≲σs≲ 6 and 1.09 ≲ x ≲ 1.11 for Type II, 6 ≲σs ≲ 15 and 1.11 ≲ x≲ 1.13 for Type III, and σs≳ 15 and x ≳ 1.13 for Type IV respectively. A simple relation is found between the temperature of γ-transformation and the composition, making possible to determine the composition of natural pyrrhotite belonging to the Type II. It is clear that the central part of the related ore deposit is occupied by pyrrhotite with smaller value of σs corresponding to that of the mineral with less iron deficiency than for that of the outer part

Teacher/Student Interpersonal Engagement And Customer Service Principles: A Phenomenological Study

The importance of understanding the effects of teacher and student engagement in online learning is especially pertinent to the online teacher and the online student as well as the college as a whole. This qualitative phenomenological study involved discovering if interpersonal online engagement between teacher and student involved those principles used in business customer service. The focus of this phenomenological study is on the lived experience of online students relative to interpersonal engagement – it is about the students’ stories. Accordingly, the questions asked what the participants felt when their teachers were engaged and if the engagement was augmented with customer service principles and, if not, what the participant felt when their instructors did not engage with them using customer service principles. Interpretative Phenomenological Analysis was used to understand and interpret findings. The study involved 10 Associate Degree nurses who were in the RN to Bachelor of Science nursing program. The data was analyzed using NVivo11 by QSR to discover the most emergent themes or patterns in the transcripts. From the collected data, four advantageous themes emerged: personalized professionalism, valued feeling, effective feedback, and good-natured humor. Additionally, there was one disadvantageous theme that emerged: lack of instructor personal approach. The importance of this study lies in the potential for transformation of the online learning environment and community

Metric Structure of the compositions by Miles Okazaki

American jazz guitarist/ composer and a professor the University of Michigan, Miles Okazaki released the revolutionary debut album Mirror in 2006, which he described as “my goal in writing the music for this album was to offer the listener a selection of rhythmic compositions that attempt to imitate the blending of formal order and organic beauty of form found in nature.” All of the music in this album owns a particular rhythmic concept as a structure of work, which is more like math and architecture along with a variety of musical styles such as Brazilian popular music, Indian, Middle-Eastern, African, classical and traditional/ contemporary jazz. In this paper, I will provide the analysis of the first track “Theme I” and the fourth track “Howl” from album Mirror which presents the best of Okazaki’s compositional style. These compositions exhibit how he utilizes rhythmic groupings, which sometimes shows a mirror/ symmetrical form over common meter as a metric structure of the piece to create a unique sound and feel. Since one part always keeps a repetitive rhythmic pattern expressing a common meter, music always produces a polyrhythmic feeling. “Howl” also features a metric modulation from 4/4 to 12/8 to 4/4 time signatures. I will also discuss how he adapts interesting melodic and harmonic structures on top of rhythmic structures, including the usage of a palindrome, pentatonic mode adaption over the augmented chord progression, slash chord, and a twelve-tone row

Thermal Studies on Mackinawite

On mackinawite mistaken for valleriite, the specimens obtained from eleven localities have been investigated especially concerning its thermal behaviors. Those discriminated under the reflection microscope on the basis of their optical characters revealing abrupt change at 130°C～250°C are classifiable into A) Kawayama type (including the specimen from Mackinaw) losing its extraordinary pleochroism and anisotropism at 130°C～160°C, B) Kômori type (including those from Muskox, Tsumo, Akagane and Ohmine) showing the similar variation at intermediate temperature and C) Outokumpu type (including those from Makimine, Besshi and Shimokawa doing so above 200°C, among which the third type only discloses transformation from mackinawite to pyrrhotite. A considerable difference in transformation temperature is commonly observable even in the specimens collected from the same locality. True valleriite, on the other hand, is stable at the temperature lower than about 500°C

On quantization of weakly nonlinear lattices. Envelope solitons

A way of quantizing weakly nonlinear lattices is proposed. It is based on introducing "pseudo-field" operators. In the new formalism quantum envelope solitons together with phonons are regarded as elementary quasi-particles making up boson gas. In the classical limit the excitations corresponding to frequencies above linear cut-off frequency are reduced to conventional envelope solitons. The approach allows one to identify the quantum soliton which is localized in space and understand existence of a narrow soliton frequency band.Comment: 5 pages. Phys. Rev. E (to appear
