The purpose of this study is to investigate the relationship between a firm’s strategy and consumers’ decisions in the presence of the paradox of choice and sharing personal information. The paradox of choice implies that having too many choices does not necessarily ensure happiness and sometimes having less is more. A new model is constructed introducing a factor of information sharing into the model of a previous study that embedded the paradox of choice only (Kinjo and Ebina in AI Soc (...) 30(2):291–297, 2015). A key feature of the model is its disutility function. It is demonstrated that if the sign of the cross derivative of the function is positive (negative) at the optimum, there is a positive (negative) correlation between the degree of sharing personal information chosen by the consumers and the number of products offered by the firm in its recommendation systems. It is also numerically indicated that the profit function of the firm becomes convex or concave depending on the shape of the disutility function. These results suggest that firms should carefully investigate the shape of the disutility function, under the paradox of choice and sharing personal information. (shrink)

The purpose of our study is to investigate the effects of the number of products, product attributes, and prices on consumer confusion, conduct a numerical analysis to check the robustness of the results, and present an example of the cell phone market in Japan. Following an ideal point model and embedding the number of products and product attributes, we clarify how these factors affect consumer confusion and purchase probability. We show that as the number of product attributes increases, the choice (...) probability of each product becomes equal, implying that consumer confusion occurs. This result is robust to the introduction of prices as strategic variables. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 21.1 (2001) 13-30 [Access article in PDF] Peace and Nonviolence from a Mahayana Buddhist Perspective: Nikkyo Niwano's Thought Michio T. Shinozaki Rissho Kosei-kai Nikkyo Niwano, the founder of Rissho Kosei-kai, taught a perspective on peace and nonviolence that I would like to explore from a Mahayana Buddhist point of view. Niwano's understanding of peace and violence and his "road" to peace are discussed. The first section (...) explores his understanding of peace as harmony at four different levels. The second section deals with the issue of the causes of violence on different levels and the precept of not-killing. The third section focuses on nonviolent action and the Bodhisattva Never Disrespectful as a model of nonviolent action. Also, the vision for overcoming hatred and violence is discussed within the context of the pacifist argument. The fourth section focuses on problems of harmony in terms of diversity and universal altruism, on the value of open forums in decision-making processes, and on Niwano's theological grounding for interreligious cooperation as a road to peace.Rissho Kosei-kai (RKK) is a Japanese Buddhist organization founded in Tokyo in 1938 by Nikkyo Niwano (1906-1999) and the late Mrs. Myoko Naganuma (1899-1957). The name "Rissho Kosei-kai" means society for establishing the true Dharma and the perfecting of selves through mutual exchange. RKK is a nonmonastic Buddhist group that draws much of its inspiration from the Lotus Sutra and claims to have six million members, largely in Japan.Nikkyo Niwano was born on November 15, 1906, in a small, poor village near Tokamachi in Nigata prefecture, which has heavy snow in winter. He was raised in a large family under one roof with another family. His harmonious and peaceful personality was the product of such circumstances. 1 He went to Tokyo to work at seventeen and took various jobs--at a rice shop, a charcoal dealer, a Japanese pickle dealer, and a milk delivery shop. In 1926, he was discharged after completing three years of naval service. He says of this experience, "One of the greatest harvests from my military experience was the reinforcement of my philosophy of nonviolence." 2 He was confident that the philosophy of nonviolence was applicable in the situation of the everyday event of military corporal punishment. [End Page 13]Upon coming to Tokyo, a new spiritual journey began with becoming acquainted with various folk religions, and he joined Reiyö-kai, practicing reverence to one's ancestors. After the founding ofRKK, Niwano received orders to report for military duty twice, in 1941 and 1945, but he was disqualified from serving in the army, so he had no battlefield experience. 3 Niwano and Naganuma were imprisoned in 1943, because the police regarded her inspirational guidance as a false and wicked religion. This was the time of the Peace Preservation Law under which religions and religious ideas were suppressed. 4Niwano preferred "not quarreling and harmony" to strife.When the faith and activities of RKK were criticized regularly for almost a month in 1956 by the nationwide newspaper TheYomiuri Shimbun,and when Soka Gakkai attacked RKK as a wicked religion and tried to start a campaign to abolish it, Niwano called them the "Yomiuri bodhisattva" and "Gakkai bodhisattva," as they could lead members to improvement and reflection on their motives and behavior. 5From inside RKK, Niwano was severely criticized and experienced being ostracized by Myoko Naganuma's ardent followers, who tried until 1957 to have her become president of RKK or establish a separate organization. He regarded this as a time for him to be tolerant and forbearing through reflecting on himself and not blaming others, and he later warmheartedly accepted his former opponents.Robert Kisala refers to Rissho Kosei-kai as follows: "After the Second World War, Rev. Nikkyo Niwano, whose activities centered around a big metropolitan urban city, advocated strengthening the solidarity of the family and local community in modern society and devoted himself to religious cooperation in order to solve social issues at an international level." 6An...

In this paper, we generalize a result of Brown and Simpson [1] to prove that RCA0+Π0∞-BCT is conservative over RCA0 with respect to the set of formulae in the form ∃!Xφ, where φ is arithmetical. We also consider the conservation of Π00∞-BCT over Σb1-NIA+∇b1-CA.

According to alethic pluralism, sentences belonging to different domains of discourse can be true by having different alethic (i.e., truth-constituting) properties. Against this pluralistic view, Jamin Asay has recently argued that pluralists' appeal to multiple alethic properties is ill-motivated because the main advantages of pluralism can already be obtained within the framework of standard truthmaker theory. In response to this objection, this paper argues that Asay's claim does not hold with respect to one of the central advantages of pluralism, namely, (...) the ability to offer a proper understanding of the realism/anti-realism debate. This is because, first, when simply construed, truthmaker theory can only provide an inadequate understanding of the debate, and second, when construed in certain ways that allow it to avoid inadequacy, it becomes committed to multiple alethic properties.

In this translation of his 1936 essay, Tosaka Jun critically examines Tanabe Hajime’s “logic of species,” paying particular attention to its basis, i.e. the logic of “absolute mediation” that Tanabe had devised earlier. In 1936, the logic of species had only been developed within a few texts, including “The Logic of Social Being” (1934–5) and “The Logic of Species and the World Schema” (1935). Interestingly enough, Tosaka agrees to a certain extent with Tanabe’s criticism of the “logic of nothingness” lying (...) at the bottom of Nishida Kitaro’s philosophy, according to which criticism the place of nothingness represents a mystical immediacy. Tosaka, however, also criticizes Tanabe’s own position, claiming that his idea of absolute mediation, in which all immediacies are mediated, leads to a logical absolutism neglecting the materiality of nature. Tosaka claims that the temporal relationship between the mediator and the mediated should be addressed in terms of a “chronology” in which nature exists prior to the subject. Not only Tosaka’s immanent criticism of Tanabe contributed to the development of the “Kyoto School” (an expression Tosaka invented himself in 1932), but the question of “chronology,” with regard to mediation, has a modern theoretical significance as a point of contention in the contemporary debate between realism and constructivism.

One most common problem in reinforcement learning systems (e.g. Q-learning) is to reduce the number of trials to converge to an optimal policy. As one of the solution to the problem, k-certainty exploration method was proposed. Miyazaki reported that this method could determine an optimal policy faster than Q-learning in Markov decision processes (MDPs). This method is very efficient learning method. But, we propose an improvement plan that makes this method more efficient. In k-certainty exploration method, in case there is (...) no k-uncertainty rule (rules which aren’t selected more than k times) in current state, an agent sometimes walks randomly until it finds a state where it can select a k-uncertainty rule. We think that this behavior is not efficient. To reduce this useless behavior, we propose combining k-certainty exploration method with Dynamic programming (DP). Miyazaki’s system uses DP after all rules are executed at least k times. But, our method uses k-certainty exploration method along with DP during learning. Our method, takes two pattern actions. In case an agent can select k-uncertainty rules, one of these rules is selected at random as k-certainty exploration method. In another case there is no k-uncertainty rule, behavior of agent is different from the behavior of k-certainty exploration method. In that case, our method uses DP to compute an optimal policy for moving from a current state to a state in which some k-uncertainty rules remain. The model for DP is constructed by using only known states. The outline will be described below. First, an agent makes a map constructed by using only known states. In the map, goals are states in which there are k-uncertainty rules and arbitrary state values are set in these states. Point to which attention should be paid is that the map is not given from outside. It is made from only experience. Next, each state values of states in which there are only k-certainty rules in the map are computed by DP (we used Policy Iteration). Finally, an agent continues to select greedy action until it arrives at a state in which it can select a k-uncertainty rule. By this improvement, we expect it can determine an optimal policy faster than k-certainty exploration method. And we have verified that our exploration method can determine an optimal policy faster than k-certainty exploration method by computer simulation. (shrink)

According to the subset view of realization, a property realizes another if the causal powers of the latter are a subset of those of the former. Against this view, some authors (in particular, Kevin Morris and Paul Audi) have argued that it has an untenable consequence that realizing properties are less fundamental than the properties they realize, because the subset view characterizes realized properties as parts (subsets) of their realizers whereas it is generally true that a part is prior to (...) its whole. This paper defends the subset view from this “part-whole” objection, by arguing that if we compare individual powers of realizer and realizee with particular attention to their manifestation conditions, it turns out that each power of a realizee is grounded in some power of its realizer. This grounding relation between powers, I shall argue, allows subset theorists to explain why a realizer is more fundamental than its realizee, even while having the latter as a part. (shrink)

The strong immanent realism (i.e., the view that there exist universals as entities capable of being wholly present wherever their instances are located) has been traditionally criticized for having certain absurd consequences. Although Gilmore (2003) replied to these criticisms by taking spatial relations involving universals as relativized to their locations, his reply has been rebutted by Keskinen et al. (2015). This paper aims to defend the strong immanent realism by proposing a new version of the relativization strategy, according to which (...) a spatial relation is to be relativized just to the extent that it contains universals or concrete particulars among its terms. This version, it will be argued, can satisfactorily address the objections hitherto posed to the strong immanent realism. (shrink)

The Manifestation Requirement, advanced by Dummett in his critique of semantic realism, has been criticized for being behavioristic, and the responses have been made that the critics are mistaken. However, the dispute has failed to exhibit the point of the Requirement. In this paper, I shall argue (1) that, in the light of Anscombe's theory of practical knowledge, knowledge of linguistic meaning is to be seen as the knowledge-how that forms the basis of the practical knowledge that an agent has (...) of his own intentional actions, (2) that such knowledge of linguistic meaning is to be based on mutual agreements in a community, and (3) that the Manifestation Requirement is a condition for the possibility of such mutual agreements. As a result, the Manifestation Requirement finds its basis on the idea that language and linguistic acts are tools that we use while continually improving them. (shrink)

If a book title were comparable to the name of a restaurant, the table of contents would be their menu. Jason Wirth's Nietzsche and Other Buddhas initially reminded me of a fusion restaurant with a strong "Asian" flavor, an ambiguous genre that we would see anywhere in continental Europe. As one could easily imagine, this is not necessarily a compliment to the chef. By integrating various ingredients and different techniques from diverse culinary traditions, a fusion restaurant might claim to create (...) a new dish or a unique course that transcends the conventional categories of our dietary practice. Like what Kant says about the uniqueness of nonsense, however, their end product could fail to be... (shrink)

This article provides the first English translation of Tanabe’s early essay, “The Limit of Logicism in Epistemology: A Critique of the Marburg and Freiburg Schools”. The key notion that the young Tanabe seeks to define in relation to his detailed analyses of contemporary Neo-Kantian epistemology is the notion of “pure experience” presented in Nishida’s philosophy. The general theory of epistemology shared among the thinkers from these two prominent schools of philosophy in early 20 th century Germany aimed to eliminate the (...) empirical residues in Kant’s theory of knowledge while opposing naïve empiricism and the uncritical methodology of positive science. Their “logicistic” approach, according to Tanabe, seems to contradict Nishida’s notion of pure experience, for it cannot allow any vestige of empiricism in its systematic framework, which is specifically designed to ground scientific knowledge. Yet given that the Neo-Kantian configuration of epistemology does not create the object of knowledge, it must face sensation or representational content as its limiting instance. Thus, to ground a Neo-Kantian theory of knowledge while taking account of this limit of logicism involves explaining their understanding of the unity of subject and object in human knowing. For this, Tanabe argues, recourse to Nishida’s notion of pure experience is indispensable. (shrink)
