Experience in Early Infancy Is Indispensable for Color Perception

AbstractEarly visual experience is indispensable to shape the maturation of cortical circuits during development [1]. Monocular deprivation in infancy, for instance, leads to an irreversible reduction of visually driven activity in the visual cortex through the deprived eye and a loss of binocular depth perception [2–4]. It was tested whether or not early experience is also necessary for color perception. Infant monkeys were reared for nearly a year in a separate room where the illumination came from only monochromatic lights. After extensive training, they were able to perform color matching. But, their judgment of color similarity was quite different from that of normal animals. Furthermore, they had severe deficits in color constancy; their color vision was very much wavelength dominated, so they could not compensate for the changes in wavelength composition. These results indicate that early visual experience is also indispensable for normal color perception

Commercial Policy and Foreign Ownership

To serve the domestic market, foreign multinationals often not only export there but also control local firms through FDI. This paper examines the effects of trade and industrial policies on prices, outputs, profits, and welfare when exports and FDI coexist. Specifically, we focus on the case in which a foreign firm has full control of a local firm through partial ownership. Cross-border ownership on the basis of both financial interests and corporate control leads to horizontal market-linkages through which tariffs and production subsidies may harm a locally-owned firm but benefit a foreign firm. Foreign ownership regulation benefits a locally-owned firm.foreign direct investment, corporate control, tariffs, production subsidies, ownership regulation

Matching, Quality, Upgrading, and Trade between Heterogeneous Firms

This paper analyzes trade between firms that are heterogeneous in product quality in a simple general equilibrium model. The multi-sided heterogeneity of exporters and importers creates a new source of gains from trade. The opening of trade raises the quality of final goods by improving matching of .rms. The quality upgrading is decomposed as the short run effect of a reduction in the quality gap among parts and components and the long run effect of intensified competition among suppliers. Under the existence of fixed trade costs, firms’ trade pattern is consistent with a variety of stylized facts that have not been explained in the conventional love of variety model. Firms selectively trade with those with similar sizes at similar quality levels. Both exporting and importing are concentrated into large and high quality firms, though not all large and high quality firms engage in trade. Trade in intermediate goods improves the quality of even firms that do not import intermediate goods.matching, heterogeneous …firms, quality, vertical differentiation, trade in intermediate goods, offshoring.

Assortative matching of exporters and importers

This paper uses the opening of the US textile/apparel market for China at the end of the Multifibre Arrangement in 2005 as a natural experiment to provide evidence for positive assortative matching of Mexican exporting firms and US importing firms by their capability. We identify three findings for liberalized products by comparing them to other textile/apparel products: (1) US importers switched their Mexican partners to those making greater preshock exports, whereas Mexican exporters switched their US partners to those making fewer preshock imports; (2) for firms who switched partners, trade volume of the old partners and the new partners are positively correlated; (3) small Mexican exporters stop exporting. We develop a model combining Becker-type matching of final producers and suppliers with the standard Melitz-type model to show that these findings are consistent with positive assortative matching but not with negative assortative matching or purely random matching. The model indicates that the findings are evidence for a new mechanism of gain from trade

Social experiment for security camera which protects privacy embedded in vending machine

AbstractWith the cooperation of Gunma Prefecture Police Department and Mikuni Coca-Cola Group, e-JIKEI Network started Experiment of Security Camera Embedded in Vending Machine on 19th June 2007. In this experiment, the system of e-JIKEI Network is embedded in a vending machine to develop a new experiment environment. In this new development, our watch over system will not be restricted to residential area, but can also be used widely even in suburb area. Up until now, the camera has been working perfectly and the experiment progressed as expected. The authors are hoping that this system work perfectly without problems for 1-year cycle

Alternation of Sound Location Induces Visual Motion Perception of a Static Object

Background: Audition provides important cues with regard to stimulus motion although vision may provide the most salient information. It has been reported that a sound of fixed intensity tends to be judged as decreasing in intensity after adaptation to looming visual stimuli or as increasing in intensity after adaptation to receding visual stimuli. This audiovisual interaction in motion aftereffects indicates that there are multimodal contributions to motion perception at early levels of sensory processing. However, there has been no report that sounds can induce the perception of visual motion. Methodology/Principal Findings: A visual stimulus blinking at a fixed location was perceived to be moving laterally when the flash onset was synchronized to an alternating left-right sound source. This illusory visual motion was strengthened with an increasing retinal eccentricity (2.5 deg to 20 deg) and occurred more frequently when the onsets of the audio and visual stimuli were synchronized. Conclusions/Significance: We clearly demonstrated that the alternation of sound location induces illusory visual motion when vision cannot provide accurate spatial information. The present findings strongly suggest that the neural representations of auditory and visual motion processing can bias each other, which yields the best estimates of externa
