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)

This paper introduces Simone Weil’s notion of reading and some of its implications to education. Weil’s philosophy, in particular her notion of attention has caught interest of some education scholars; however, the existing studies are still underdeveloped. Introducing Weil’s notion of reading, which has not been studied almost at all by educationists but its significance is well-recognized by Weil scholars, I intend to set forth a more nuanced understanding of Weil’s attention that is necessary to further discuss Weil’s potential contribution (...) to education research. Attention to other people, hence love of others, is reframed as “reading better.” We read better not simply by purifying our reading through detachment and self-negation, which is how the notion of attention is often understood and thus found problematic, but by incorporating multiple perspectives and finding balance among them. Learning to read better, then, is not merely inward effort of detachment done through introspection, but it also necessarily involves outward effort of working with other people and the world. It is through interacting with others, we may learn our own readings, recognize others’ readings, and seeking for just balance among them. This latter element which has been greatly dismissed is indispensable for any serious discussions of Weil’s philosophy in education. (shrink)

According to the “truthmaker maximalism”, every true contingent proposition is made true by something in the world, called its truthmaker. Although at first sight the maximalism seems to be a natural position, it has serious difficulties, especially concerning negative truths. In view of this, many truthmaker theorists adopt some non-maximalist position. It is not clear, however, whether these non-maximalists are justified, since existing reasons to justify the non-maximalism are not good enough. In this paper, then, I shall propose a new (...) reason for the non-maximalism, which consists in the observation that the maximalism cannot acknowledge the widely accepted view that certain inferences involving logical constants are valid in the properly logical sense.

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)

Cet article analyse quelques extraits de messages de santé traduits du français vers le mooré, l'une des principales langues du Burkina Faso. Partant du fait que langue et culture sont étroitement liées, et que la langue exprime une vision du monde qui lui est propre, nous nous interrogeons sur les valeurs que véhicule la traduction en tant qu'acte de communication. L'analyse montre qu'au-delà de leur fonction informative, les messages traduits véhiculent des valeurs qui appartiennent soit à la culture des textes (...) sources soit à celle des textes cibles. Il est cependant clair qu'au lieu d'une approche basée sur l'équivalence, la traduction des messages de santé dans les langues africaines doit viser plutôt la fonctionnalité, approche qui met le public cible et sa culture au centre de ses préoccupations.This article analyzes some excerpts health messages translated from French to Moore, one of the main languages ​​of Burkina Faso. Given the fact that language and culture are closely related, and that the language expresses a worldview of its own, we wonder about the values ​​that the vehicle translation as an act of communication. The analysis shows that beyond their informative function, the translated messages convey values ​​that belong to either culture or source texts in the target texts. It is clear, however, that instead of an approach based on equivalence, translation of health messages in African languages ​​should aim rather functionality, an approach that puts the target audience and its culture at the center of its concerns.

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.

Presentism is usually understood as the thesis that only the present exists whereas the rival theory of eternalism is usually understood as the thesis that past, present, and future things are all equally real. The significance of this debate has been threatened by the so-called triviality objection, which allegedly shows that the presentist thesis is either trivially true or obviously false: Presentism is trivially true if it is read as saying that everything that exists now is present, and it is (...) obviously false if read as saying that everything that has existed, exits or will exist is present. If eternalism is taken as the negation of presentism, it is also either trivially false or obviously true. In this paper, I try to respond to the triviality objection on behalf of presentism. In second section, I will examine how the argument proceeds. In third section, I will reflect on three possible ways to respond but will argue that none of them succeeds in giving a satisfactory solution. I will then try to clarify the core idea of presentism and to suggest that if we characterise presentism accurately, the problem will disappear. In fourth section, I will offer a plausible definition of presentism and will show how it can avoid the triviality objection and demonstrate why it is advantageous to accept the version of presentism I offer.

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)

This is a review essay on Daisuke Kachi’s recent book, Agents: Contemporary Substance Ontology (sic. Shunjusha, 2018). The book develops and partially defends an ontology that takes the category of substance as the most fundamental one. The author provides in it a new perspective on substance, which consists in characterizing substances as bearers of what he calls “substance modalities” (of which there are four kinds, that stem from the factors of essence, power, past persistence, and future persistence respectively). The first (...) part of this review essay gives an extended overview of Kachi’s book while the second discusses some problems it may face. (shrink)

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)

Le Burkina Faso comporte, en plus du français, « langue officielle », environ une soixantaine de langues locales dites « langues nationales ». Malgré des lois favorables à l’égalité des langues, on constate dans la pratique une hiérarchisation linguistique qui consacre la domination du français sur les autres langues. Dans ce contexte plurilingue, on pouvait s’attendre à ce que la traduction puisse contribuer à la préservation de la diversité linguistique et culturelle du pays, voire à l’enrichissement des langues nationales. Mais (...) l’analyse de la traduction littéraire et audio-visuelle révèle une direction qui reflète cette hiérarchisation des langues. En effet, la traduction entre langues européennes est de loin la plus importante, en particulier entre le français et l’anglais. La traduction entre les langues nationales n’existe pas. Dans le domaine audio-visuel, en particulier le cinéma, le sous-titrage se fait toujours des langues nationales vers les langues européennes. En l’absence d’une politique linguistique et d’une politique de traduction, la traduction ne peut pas jouer son rôle de promotion des langues et de préservation de la diversité culturelle.As well as French, its “official language”, Burkina Faso has about 60 local languages that are referred to as “national languages”. Despite legislation in favour of language equality, there is, in practice, a distinct hierarchy that has enshrined the domination of French over other languages. In this multilingual context, it might have been expected that translation would help to preserve the country’s linguistic and cultural diversity, and even to enrich its national languages. However, our analysis of literary and audio-visual translations shows that the translating directions reflect the existing hierarchy between languages. Translations between European languages are by far the most common, especially between French and English. There is no translation at all between the national languages. In the audiovisual field, especially in films, sub-titles are always translated from national languages into European languages. Without language or translation policies, translation cannot play its part in promoting languages and preserving cultural diversity. (shrink)
