The media coverage and public awareness of environmental issues in Japan

Gazette (Leiden Netherlands) (1995)

Shunji Mikami Toshio Takeshita M. Nakada Miki Kawabata

This paper examines how mass media in Japan influenced upon the public awareness of the global environmental issues during and prior to the Earth Summit (UNCED) in 1992. Our survey revealed substantial public concern about environmental issues in Japan. Content analysis of television news during the UNCED, however, found relatively weak relationship between the salient environmental issues of the audience and the portrayal of environmental issues in television news during the UNCED. An agenda-setting study of the newspapers during and before the UNCED showed a gradual and cumulative nature of the effects rather than the immediate effects. The amount of television viewing and the attitudes toward environmental tax showed positive association, after controlling for demographic variables, which suggested cultivation effects of the media.

Ultrawide range dielectric spectroscopy of BaTiO3-based perovskite dielectrics

Applied Physics Letters (2007)

Takaaki Tsurumi Jingze Li Takuya Hoshina Hirofumi Kakemoto M. Nakada

Ultrawide range dielectric spectra from the kilohertz to terahertz range of BaTiO3 (BT), Ba(Zr0.25Ti0.75)O3 (BZT), (Ba0.6Sr0.4)TiO3 (BST), and SrTiO3 ceramics were presented by analyzing dielectric permittivity and IR reflectivity data. It was found that the permittivity of the ST was determined only by the ionic polarization while that of the BT was determined by the ionic polarization as well as the dipole polarization due to the domain contribution. The high permittivity of the BZT ceramics was attributed to the dipole polarization of polar nanoregions in the relaxors. The dipole and ionic polarizations overlapped in the BST.

The Public / Private Debate

IGI Global eBooks (2009)

M. Nakada Rafael Capurro

In this article we give an overview of the range and characteristics of intercultural information ethics (IIE) focusing on the public/private debate in the so-called information age. IIE is a relatively newly emerging field which addresses a variety of issues such as similarities and differences of views on the public/private spheres in different cultural and social traditions, the comparative analysis of moral norms of communication in global information network(s) or the Seken-Shakai-Ikai trichotomy as a specific typology of structures underlying today’s Japanese information society. We examine these problems, in particular the public/private debate, from a perspective in which cultural differences arise from the underlying dimension of sharing with others a common world and with special reference to the differences between Japanese and Western culture(s).

A Silicon Photonics Approach for the Nanotechnology Era

Keishi Ohashi Kenichi Nishi Takanori Shimizu M. Nakada Junichi Fujikata

With the further scaling of feature size in the nanotechnology era, on-chip optical interconnection will be essential for meeting high-capacity data transmission needs. This paper describes a silicon photonics approach to achieving cost-effective and low-power-consumption on-chip optical interconnects, which includes the use of a small ceramic electro-optical modulator and a Si nano-photodiode coupled with a SiON/SiO ₂ waveguide, and discusses it in comparison with other approaches.

High density Land/Groove recording

IEEE Transactions on Magnetics (1995)

Toshiaki Iwanaga M. Nakada Ryuichi Katayama

In order to achieve higher area-density magneto-optical recording, the land and groove area recording (Land/Groove recording) technique has been developed. Land/Groove recording, in combination with a crosstalk canceller technique and the PRML (Partial Response Maximum Likelihood) technique, has the potential for achieving over 10/spl times/ MO recording. Moreover, it is also possible to accomplish 16/spl times/ MO recording, using a blue-green laser head combined system.

Low temperature crystal growth of MnBi films

IEEE Transactions on Magnetics (1994)

M. Nakada Mitsuya Okada

The relation between deposition conditions of Bi and Mn layers and crystal growth of MnBi were investigated to reduce the MnBi annealing temperature for its application to a magneto-optical disk. We found that higher c-axis orientation of the hexagonal Bi layer and lower Mn oxide concentration in the Mn layer reduces the annealing temperature. Growth of MnBi below 150/spl deg/C, which is much lower than the decomposition temperature of photo-polymer (about 200/spl deg/C), was achieved by optimizing deposition conditions of Bi and Mn layers.< >
