This paper first shows that some versions of the logic R of Relevance do not satisfy the relevance principle introduced by Anderson and Belnap, the principle of which is generally accepted as the principle for relevance. After considering several possible (but defective) improvements of the relevance principle, this paper presents a new relevance principle for (three versions of) R, and explains why this principle is better than the original and others.

This paper proposes a new topic in substructural logic for use in research joining the fields of relevance and fuzzy logics. For this, we consider old and new relevance principles. We first introduce fuzzy systems satisfying an old relevance principle, that is, Dunn’s weak relevance principle. We present ways to obtain relevant companions of the weakening-free uninorm systems introduced by Metcalfe and Montagna and fuzzy companions of the system R of relevant implication and its neighbors. The algebraic structures corresponding to (...) the systems are then defined, and completeness results are provided. We next consider fuzzy systems satisfying new relevance principles introduced by Yang. We show that the weakening-free uninorm systems and some extensions and neighbors of R satisfy the new relevance principles. (shrink)

With the advancement of medical technology, various life-sustaining treatments are available at the end of life. Older adults should be encouraged to establish their end-of-life treatment preferences (ELTP) while they are physically and mentally able to do so. The purpose of this study was to explore ELTP among older adults and to compare those preferences in a subset of individuals who had reported their ELTP in a survey completed the previous year. This was a descriptive study of 191 older adults (...) living in a continuing care retirement community. Approximately half of the participants did not want cardiopulmonary resuscitation, to be put on a respirator, or to receive dialysis. The findings in this study suggest that many older adults do not want aggressive interventions at the end of life, but choose rather those measures that will keep them comfortable. Moreover, treatment choices may change over time. Health care providers should initiate discussions about ELTP at regular intervals (yearly) to assist older adults in dictating their end-of-life care. (shrink)

This article attempts to fill a gap in International Relations literature on East Asian security. ‘East Asia’ appears to be mostly an indeterminate conceptual construct, allowing scholars to look selectively at those aspects and areas that could justify their security thesis, albeit security dynamics in the region are all too difficult to comprehend and predict. This problem has been frequently pointed out in IR literature, but its methodological implications and suggestions have neither been appropriately illuminated nor been systematically offered, and (...) the main solution commonly found in the literature was the tautological one of ‘better defining’ the region. As an alternative, this article suggests that one needs to tighten geographical focus and differentiate the subjects of analysis. When it comes to the study of East Asian security, one needs to aim to develop specific and differentiated generalizations as opposed to generalizations of a broad character. To showcase the fact that research outcomes can be more determinate when the target of analysis is more focused and specified, this article takes Northeast Asian security as an example and challenges the so-called ‘peaceful East Asia’ thesis, one of the mainstream perspectives on East Asian security. This article ultimately argues that while apprehending East Asian security dynamics through delimiting the scope of analysis and circumscribing the subjects of investigation is often deemed to be a modest enterprise―in particular, in terms of generalizability―the merits are substantial: research outcomes will be able not only to give us a truer mapping of the real world, but also bring us closer to building knowledge which satisfies the scientific criterion of ‘falsifiability.’Export citation Request permission.

In contrast to the juxtaposition of representative democracy and Confucian meritocracy that is currently being discussed in international political theory, we start from the hypothesis of a historical, intercultural and logical, simultaneous provenance of democracy and meritocracy in the evolution of the modern constitutional state. To this end, we examine the reception of Confucianism in the republican history of ideas of European Enlightenment using selected examples ranging from Leibniz to the classical constitutional and government theory of Sieyès. The widespread ignorance (...) of the Confucian elements in the classical core of modern republicanism that we have evaluated here is attributed to the needs of political legitimacy and the methodical ahistorism and historical amnesia of academic discourse.

This paper considers standard completeness for fixed-pointed involutive micanorm-based logics. For this, we first discuss fixed-pointed involutive micanorm-based logics together with their algebraic semantics. Next, after introducing some examples of fixed-pointed involutive micanorms, we provide standard completeness results for those logics.

In this paper we investigate some logics with weak Boolean negation , calling wB logics, obtained by dualizing intuitionistic negation . We first provide Routley-Meyer semantics for wB-IC , its neighbors wB-LC, wB-LC* ), and wB-S4, wB-S4c . We give completeness for each of them by using RM semantics. We next provide RM semantics for IC, the Dummett's LC, the wB-S4 with ¬ in place of − , and the pB-S4 with c , and give completeness for each system. Finally, (...) we give a translation of the classical propositional logic PC into wB-IC, and a translation of PC into wB-S4c.1. (shrink)

In empiricism, there are only two answers for a question: black or white. Yet, subjective meanings of human behaviours and responses toward health and illness cannot be simply explained with black and white. Gray zones are needed because they are characterized by complexity and require a contextual understanding. In this paper, we present and suggest fuzzy logic as an example of theoretical bases that help transcend the conflicts between objectivity and subjectivity, respect gray zones between black and white answers for (...) questions, and provide a contextual understanding of complex nursing phenomenon. A historical review of fuzzy logic is followed by a definition of fuzzy logic. Then, fuzzy logic is discussed in terms of its compatibility with nursing epistemological views and philosophical thoughts. Fuzzy logic agrees with three categories of epistemological views of nursing, including correspondence, coherence and pragmatism. Fuzzy logic also agrees with four major philosophical thoughts in nursing, including postempiricism, pragmatism, feminism, and postmodernism. Based on the discussion, we propose that fuzzy logic be further explored, used and developed in research and practice in the nursing areas/situations/phenomena that are characterized by complexity, ambiguousness, and vagueness.

This paper combines two classes of generalized logics, one of which is the class of weakly implicative logics introduced by Cintula and the other of which is the class of gaggle logics introduced by Dunn. For this purpose we introduce implicational tonoid logics. More precisely, we first define implicational tonoid logics in general and examine their relation to weakly implicative logics. We then provide algebraic semantics for implicational tonoid logics. Finally, we consider relational semantics, called Routley–Meyer–style semantics, for finitary those (...) logics. (shrink)

In the 1990s P.H. Hirst criticizes his influential forms of knowledge theory, suggesting a new concept of education. In this paper I explain why Hirst suggests the new concept of ‘education as initiation into practices’. Although the latter Hirst’s position had positive implications on education, it is frequently confused with theutilitarian position. In order to provide a more coherent concept of education, I compare basic features of the rationalist (R), the utilitarian (U), and the practices-based (P) approach. Then I discuss (...) the implications of this concept. The main features of R, U, and P are respectively as this: 1) A person is seen as a rational being, a being of wants and desires, and a rational practitioner who is socially constructed. 2) The nature of reason is conceived as ‘rational’,‘instrumental’, and ‘practical’. 3) The aim of education is education for theoretical rationality, education for maximum satisfaction of desires, and education for identity formation by participating in practices. 4) The contents of education are theoretical knowledge, instrumental knowledge with utility, and practical knowledge for various practices. 5) R pursues absolute transcendental values, U pursues extrinsic instrumental values, and P pursues values internal to a practice. 6) R conceives education as ‘seeing’, U as ‘doing’, and I suggest ‘listening’ model for P. Based on this conception of practices-based position, I hope we can provide better education. (shrink)

Der Konfuzianismus ist auch im Westen keine unbekannte Lehre mehr. Zugleich trifft man ihr gegenüber auf erhebliche Vorurteile. Insbesondere im Zusammenhang mit der Debatte um den Kommunitarismus wird der Konfuzianismus häufig als kulturelle Grundlage autoritärer politischer Herrschaft hingestellt. Das ist nicht vollkommen falsch, beruht aber auf einer einseitigen Wahrnehmung des Konfuzianismus. Tatsächlich blickt dieser auf eine lange Geschichte politischer Instrumentalisierungen zurück. Gleichwohl enthält diese Lehre Konzepte, die dem gemeinschaftlichen Zusammenleben förderlich sein können.

This paper deals with one kind of Kripke-style semantics, which we shall call algebraic Kripke-style semantics, for relevance logics. We first recall the logic R of relevant implication and some closely related systems, their corresponding algebraic structures, and algebraic completeness results. We provide simpler algebraic completeness proofs. We then introduce various types of algebraic Kripke-style semantics for these systems and connect them with algebraic semantics.

Here algebraic Routley-Meyer semantics is addressed for two fuzzy versions of the logic of relevant implication R. To this end, two versions R t and R T of R and their fuzzy extensions FRt and FRT , respectively, are first discussed together with their algebraic semantics. Next algebraic Routley-Meyer semantics for these two fuzzy extensions is introduced. Finally, it is verified that these logics are sound and complete over the semantics.

The use of smartphones has become commonplace, even among people with disabilities. The purpose of this study was to investigate the effect of smartphone use on the negative emotions of people with visual impairment. This study analyzed data from 30 respondents with visual impairments obtained from the 2016 Internet Overdependence Survey in South Korea. The analysis was based on partial least squares regression with information search, leisure, communication, and online transactions as independent variables, and negative emotions comprising depression, anxiety, and (...) loneliness as the dependent variables. Among people with visual impairment, the use of smartphones as a means of communication decreased negative emotions while their use for leisure or information search was related to an increase in negative emotions such as depression and loneliness. Use for information retrieval was found to be associated with a low level of anxiety, and use for online transactions was associated with low loneliness. The results of this study showed that the use of the Internet can be a means of providing interaction opportunities and reducing negation emotions for people with visual impairment. (shrink)

The study reviewed 20 currently-available structured ethical decision-making models and developed an integrated model consisting of six steps with useful questions and tools that help better performance each step: (1) the identification of an ethical problem; (2) the collection of additional information to identify the problem and develop solutions; (3) the development of alternatives for analysis and comparison; (4) the selection of the best alternatives and justification; (5) the development of diverse, practical ways to implement ethical decisions and actions; and (...) (6) the evaluation of effects and development of strategies to prevent a similar occurrence. From a pilot-test of the model, nursing students reported positive experiences, including being satisfied with having access to a comprehensive review process of the ethical aspects of decision making and becoming more confident in their decisions. There is a need for the model to be further tested and refined in both the educational and practical environments. (shrink)

The zone of proximal development (ZPD) is defined as an overarching concept that integrates the main tenets of Vygotsky’s theory of human development. The conceptualization of the ZPD begins with its social, cultural, and historical context and traces its development as a spatial and temporal metaphor that reflects the sociogenetic root of all human mental functioning. Beyond the explication of sociogenesis, the ZPD is reconceptualized to include the notions of voice and dialogicality. The insights gained from the fields of semiotics (...) and discourse studies allow a broader understanding of the ZPD by bringing to light participant structures and institutional and historical forces that may not have been included in the dominant interpretations of the ZPD.

This study examined influential factors of newspaper corporation social responsibility and evaluated corporate social responsibility using a newspaper corporate social responsibility index. Results of this study, which was conducted by survey, showed that arbitrative, essential, and cultural activities were influential factors comprised of newspaper corporate social responsibility. In addition, the findings indicated that higher corporate social responsibility index was not accompanied by Korean newspaper corporations with larger circulations.

This article investigates Kripke-style semantics for two sorts of logics: pseudo-Boolean and weak-Boolean logics. As examples of the first, we introduce G3 and S53pB.G3 is the three-valued Dummett–Gödel logic; S53pB is the modal logic S5 but with its orthonegation replaced by a pB negation. Examples of wB logic are G3wB and S53wB.G3wB is G3 with a wB negation in place of its pB negation; S53wB is S5 with a wB negation replacing its orthonegation. For each system, we provide a three-valued (...) Kripke-style semantics with and without star operation . We prove soundness and completeness theorems in each case. Note that wB logics may be equivalent to logics with Baaz’s projection Δ. We finally introduce the G3 and the S53pB both with Δ and show that they are equivalent to G3wB and S53wB, respectively.

By probing into how desire is involved in fashion phenomena, this article illuminates Willkür in tandem with desire. It first analyzes how the higher and lower faculties of desire, spelled out by Immanuel Kant, play a role in fashion, unveiling how fashion as a form of social relations exists in concert with the higher faculty of desire, which has a close connection with Willkür. This article maintains that the arbitrary choice manifested in and through fashion is illustrative of Willkür, on (...) the grounds that it results from a self-conscious deliberation, demonstrating the ‘reflective distance’ from our incentives. Christine M. Korsgaard’s elucidation of the relationship between ‘reflective distance’ and self-consciousness helps formulate this argument. However, this article also discusses the foibles of Korsgaard’s reading of Kant, in particular in the area of theory of action. By doing so, this article argues that reason is not the only factor with which we make choices and take actions within the bounds of which freedom is secured, and that fashion allows us to comprehend not only how the power of choice, independent from necessitation by sensible impulses, exercises its freedom, but also how personal autonomy is related to Kant’s negative concept of freedom.
