    Liberating classical negation from falsity conditions

    No full text
    In one of their papers, Michael De and Hitoshi Omori observed that the notion of classical negation is not uniquely determined in the context of so-called Belnap-Dunn logic, and in fact there are 16 unary operations that qualify to be called classical negation. These varieties are due to different falsity conditions one may assume for classical negation. The aim of this paper is to observe that there is an interesting way to make sense of classical negation independent of falsity conditions. We discuss two equivalent semantics, and offer a Hilbert-style system that is sound and complete with respect to the semantics

    A Note on Goddard and Routley's Significance Logic

    No full text
    The present note revisits the joint work of Leonard Goddard and Richard Routley on significance logics with the aim of shedding new light on their understanding by studying them under the lens of recent semantic developments, such as the plurivalent semantics developed by Graham Priest. These semantics allow sentences to receive one, more than one, or no truth-value at all from a given carrier set. Since nonsignificant sentences are taken to be neither true nor false, i.e. truth-value gaps, in this essay we show that with the aid of plurivalent semantics it is possible to straightforwardly instantiate Goddard and Routley's understanding of how the connectives should work within significance logics.Fil: Szmuc, Damián Enrique.

    Town Planning for the East Gate Area of Omori Station: A Study

    No full text
    The author surveyed the East Gate area of Omori Station which is in Ota-ward, Tokyo, for the purpose of collecting data useful in future town planning. First, the history and physical environment of Omori since the Edo Period, including its location, changes in the townscape of houses and buildings, and demographics are explained.   According to surveys by the ward, the population of the residents has been increasing, but the numbers of households has been decreasing for the past 27 years, and many of the ward residents hope to live in the area long term.   The author distributed a questionnaire asking about how residents of the area live. 51 parents of local elementary children and 76 local council members involved in town planning, members of neighborhood associations, and shopkeepers responded; more than half of the parents had lived in the district for less than 20 years while most of the latter respondents had lived in the district for more than 40 years. The neighborhood association members who lived near the shopping streets responded that they buy things at shops on those streets daily while many younger parents tended to respond that they are not regular customers of the shops in the shopping streets. An additional survey of traffic routes showed that many people travel on the shopping streets to the station and many people visit the shopping streets by bicycle.   The author suggests that the importance of communal gathering places in the district must also be taken into account by those hoping to invigorate it.departmental bulletin pape

    Transforming Selves: Identity, History, and Autonomy among Roman Catholics in Tokyo

    No full text
    Title: Transforming Selves: Identity, History, and Autonomy among Roman Catholics in Tokyo, Author: Hisako Omori, Location: MillsThis dissertation on Roman Catholic communities in contemporary Tokyo examines ways in which individuals (re)construct and (re)negotiate their social, cultural and religious identities using Roman Catholicism. In particular, this study documents the transformative processes associated with becoming Catholic in contemporary Tokyo. Past scholarship has established that the Japanese sense of self can be characterized as "relational" when compared with American and/or Western notions of the self. I argue that this "relational" sense of self has been shaped through discursive processes in Japanese history which have emphasized a Neo-Confucian based system of ethics. I further argue that when converts deepen their understanding of the Catholic world view, they experience a new power structure in which human authority is significantly diminished. This re-structuring of authority results in a sense of liberation and elation for these Japanese Catholics, whose sense of self has previously been shaped by social obligations and by the Japanese emphasis on the social order and the authority of human beings. The culturally sanctioned relational sense of self is often transformed to a less relational one which privileges the notion of integrity, thereby creating an autonomous self that is analogous to the Western notion of the individual. By situating social actors within particular historical trajectories that the nation has taken, this study illuminates the ways in which history and power inform the sense of self in Japan.ThesisDoctor of Philosophy (PhD

Plasma xanthine oxidoreductase activity in Japanese patients with type 2 diabetes across hospitalized treatment. J Diabetes Investig. 2020.Aims/Introduction: Xanthine oxidoreductase (XOR) is an enzyme that catalyzes hypoxanthine and xanthine to xanthine and uric acid, respectively. Plasma XOR activity has recently been measured in humans. However, limited information is known about plasma XOR activity in patients with type 2 diabetes mellitus, and its changes after short-term glycemic control treatment. Materials and Methods: We enrolled 28 Japanese patients (10 men/18 women) with type 2 diabetes mellitus who were hospitalized to undergo medical treatment for diabetes. Plasma XOR activity, quantified using triple quadrupole mass spectrometry and liquid chromatography, and other clinical parameters were examined at admission and 2 weeks after treatment during hospitalization. Changes in plasma XOR activity after treatment during hospitalization and associated clinical parameters were assessed. Results: At the time of admission, the median plasma XOR activity was 83.1 pmol/h/mL, with a wide range of 14.4–1150 pmol/h/mL. Multiple regression analysis identified serum aspartate transaminase and alanine transaminase levels as significant and independent factors correlating with the baseline plasma XOR. Two weeks of treatment during hospitalization was associated with a significant decrease in plasma XOR activity. Changes in serum aspartate transaminase were also the only significant and independent factor correlating with changes in plasma XOR activity. Conclusions: A close relationship was observed between plasma XOR activity and liver transaminases in patients with type 2 diabetes mellitus, cross-sectionally, and also across treatment during hospitalization

    Is S5 Paraconsistent?

    The aim of this note is to examine the claim of B´eziau that S5 is paraconsistent. In particular, I wish to clarify what exactly is implicitly assumed behind his claim, and how we might be able to assess the claim “S5 is paraconsistent”
