  1. Should We Take Up the Slack?: Reflections on Non-ideal Theory in Ethics.Satoshi Fukuma - 2022 - Philosophia 50 (4):1825-1844.
    This article asks whether our moral duties are created by others’ non-compliance and whether we should fulfill them or not. For example, do we need to donate more of our income to eradicate world poverty because billionaires do not donate? If so, how much should we donate? In short, should we make up for others’ defaulting on their moral duties – and if so, how and to what extent? Such situations are called non-ideal circumstances in political philosophy. With the increasing (...)

  2. Activity in early visual areas predicts interindividual differences in binocular rivalry dynamics.Hiroyuki Yamashiro, Hiroki Yamamoto, Hiroaki Mano, Masahiro Umeda, Toshihiro Higuchi & Jun Saiki - 2014 - Journal of Neurophysiology 111:1190-1202.
    When dissimilar images are presented to the two eyes, binocular rivalry (BR) occurs, and perception alternates spontaneously between the images. Although neural correlates of the oscillating perception during BR have been found in multiple sites along the visual pathway, the source of BR dynamics is unclear. Psychophysical and modeling studies suggest that both low- and high-level cortical processes underlie BR dynamics. Previous neuroimaging studies have demonstrated the involvement of high-level regions by showing that frontal and parietal cortices responded time locked (...)

  3. Neural Correlates of Color-Selective Metacontrast in Human Early Retinotopic Areas.Kiyohiro Maeda, Hiroki Yamamoto, Masaki Fukunaga, Masahior Umeda, Chuzo Tanaka & Yoshimichi Ejima - 2010 - Journal of Neurophysiology 104:2291-2301.
    Metacontrast is a visual illusion in which the visibility of a target stimulus is virtually lost when immediately followed by a nonoverlapping mask stimulus. For a colored target, metacontrast is color-selective, with target visibility markedly reduced when the mask and target are the same color, but only slightly reduced when the colors differ. This study investigated neural correlates of color-selective metacontrast for cone-opponent red and green stimuli in the human V1, V2, and V3 using functional magnetic resonance imaging. Neural activity (...)

  4. Killing in the Name of Care.Joel Michael Reynolds - 2018 - Levinas Studies 12:141-164.
    On 26 July 2016, Satoshi Uematsu murdered 19 and injured 26 at a caregiving facility in Sagamihara, Japan, making it the country’s worst mass killing since WWII. In this article, I offer an analysis of the Sagamihara 19 massacre. I draw on the work of Julia Kristeva and Emmanuel Levinas to argue that claims about disability experience are insufficient to justify normative projects. In short, disability is normatively ambiguous.

  5. Electronic Coins.Craig Warmke - 2022 - Cryptoeconomic Systems 2 (1).
    In the bitcoin whitepaper, Satoshi Nakamoto (2008: 2) defines an electronic coin as a chain of digital signatures. Many have since defined a bitcoin as a chain of digital signatures. This latter definition continues to appear in reports from central banks, advocacy centers, and governments, as well as in academic papers across the disciplines of law, economics, computer science, cryptography, management, and philosophy. Some have even used it to argue that what we now call bitcoin is not the real (...)
