This article provides a systematic analysis of social choice theory without the Pareto principle, by revisiting the method of Murakami Yasusuke. This article consists of two parts. The first part investigates the relationship between rationality of social preference and the axioms that make a collective choice rule either Paretian or anti-Paretian. In the second part, the results in the first part are applied to obtain impossibility results under various rationality requirements of social preference, such as S-consistency, quasi-transitivity, semi-transitivity, (...) the interval-order property, and acyclicity.

頽廃に至っても、いまだ発現する偶然への希望はある。しかし、頽廃、すなわち消尽に至るならば、無と慨嘆の現実しかありえない。希望の存立自体、五分の可能性に生きる偶然なのである。.

Persons with visual impairments (hereafter PVI) detect and discover obstacles and road conditions by touching with a white cane when walking on the streets. In one training session, an Orientation and Mobility specialist (hereafter SPT) guided a PVI by grasping and moving the cane that the PVI was holding. We conducted a multimodal analysis of two instruction sequences, one a "proving and achieving" demonstration (Sacks in Lectures on conversation, Blackwell, 1992) and the other a "learnable" (Zemel and Koschmann, in Discourse (...) Stud 16:163–183, 2014) demonstration. The achieving demonstration proved the assessment of the PVI's performance. In the "learnable" demonstration, the PVI was able to receive and perform the most critical part of the "learnable" of the long contact touch without the aid of talk. Sharing a single cane touch is an efficient way for both the guiding SPT and the guided PVI to jointly experience and understand the environmental features. The SPT did not need to verbally confirm that the guided touch was accountable to the PVI and seemed confident that intersubjectivity with the PVI had been established. A unique form of being with others and achieving intersubjectivity in society was identified. In traditional learning instruction, it has been assumed that the learnable is presented and communicated visually and audibly. However, through guided touch learnable is presented and conveyed effectively in the cases of this paper. It seems that the sense of touch has been considered to be just for the occasion, but this is an example of something that is not just for the occasion but is consequential, that is, usable for further occasions. The data is in Japanese. (shrink)

Product recommendation system is realized by applying business rules acquired by data maining techniques. Business rules such as demographical patterns of purchase, are able to cover the groups of users that have a tendency to purchase products, but it is difficult to recommend products adaptive to various personal preferences only by utilizing them. In addition to that, it is very costly to gather the large volume of high quality survey data, which is necessary for good recommendation based on personal preference (...) model. A method collecting kansei information automatically without questionnaire survey is required. The constructing personal preference model from less favor data is also necessary, since it is costly for the user to input favor data. In this paper, we propose product recommendation system based on kansei information extracted by text mining and user's preference model constructed by Category-guided Adaptive Modeling, CAM for short. CAM is a feature construction method that can generate new features constructing the space where same labeled examples are close and different labeled examples are far away from some labeled examples. It is possible to construct personal preference model by CAM despite less information of likes and dislikes categories. In the system, retrieval agent gathers the products' specification and user agent manages preference model, user's likes and dislikes. Kansei information of the products is gained by applying text mining technique to the reputation documents about the products on the web site. We carry out some experimental studies to make sure that prefrence model obtained by our method performs effectively. (shrink)

Let M be a model of first order Peano arithmetic and I an initial segment of M that is closed under multiplication. LetM0 be the {0, 1,+}-reduct ofM. We show that there is another model N of PA that is also an expansion of M0 such that a · Ma = a · Na if and only if a ∈ I for all a ∈ M.

Future practitioners of sustainable agriculture and agroecology must have the capacity to address the wicked problems in the food system to make progress toward sustainability. Undergraduate sustainable agriculture students from a variety of backgrounds may struggle with the question, is the challenging and complex work of addressing wicked problems of agroecology for me? Our case study investigated sociocultural tensions associated with identity encountered when wicked problems teaching units were integrated into the Advanced Practices of Sustainable Agriculture course at a large, (...) Midwestern Land Grant University. The research and course employed a four-part framework that focused on attending to individual needs and identities, facilitating practice-based and community-based learning, engaging in problems situated in regional contexts, and supporting awareness of local and global political and ecological issues. Researchers used a community of practice theoretical lens, and focused on the sociocultural tensions that may have impacted individual and community identity formation. Two wicked problems teaching units are described by drawing upon documentation and audio recordings from planning meetings, course sessions, student and instructor interviews, and course artifacts. Vignettes were constructed to situate four interrelated types of sociocultural tensions encountered by instructors and students. These tensions reflected forces at the individual, community, local, and global levels which interact to influence learners’ capacity to become full participants in sustainable agriculture. The study fills a gap related to affective dimensions of learning like identity in agroecology education. Dilemmas and implications related to identity, pedagogy, and epistemology are discussed.

A bounded ultrasheaf is a nonstandard universe constructed from a superstructure in a Boolean valued model of set theory. We consider the bounded elementary embeddings between bounded ultrasheaves. Then the standardization principle is true if and only if the ultrafilters are comparable by the Rudin-Frolik order. The base concept is that the bounded elementary embeddings correspond to the complete Boolean homomorphisms. We represent this by the Rudin-Keisler order of ultrafilters of Boolean algebras.

Parties are back, and many are cheering. Party polarization has voters seeing stark differences between Democrats and Republicans and demonstrating more ideological constraint than previous generations. But these signs of a more “responsible” electorate are an illusion, because the public is no more knowledgeable than ever about the type of “information” it needs if it is to exercise effective control over the public‐policy outcomes it cares the most about. Indeed, polarization has produced a political environment where both voters and policy (...) makers may be less likely to learn about the potential consequences of their governing choices. The result is that holding elected politicians to account for policies treated as divisive ends in themselves has become easier—but that holding them accountable for policies intended as means to the achievement of consensual ends has become harder.

A few findings from our laboratory are provided as evidence favoring “isomrphism” in filling-in. One is the responsivity of macaque-cortical area V1 cells to a stimulus designed for surface filling-in at the blind spot. Another is a phenomenological observation of motion aftereffect confined within a filled-in surface at the blind spot. Our recent study on the monkey's perception of surface filling-in at a scotoma is also mentioned.

Futabatei Shimei (1864-1909) was an early modern Japanese novelist, translator, and critic. He wrote what is now generally conceived of as the first Japanese ‘modern’ novel, Drifting Clouds (1887-89). He translated works by Turgenev, Leo Tolstoy, Garshin, Gorky, and others. He also published a number of critical essays, treatises on literary theory, political papers, and so forth. His early translation of Turgenev’s short stories: Aibiki (Rendevous, 1888) and Meguriai (Three Trysts, 1889) were extremely influential on the contemporary literati, who were (...) amazed at the fresh, poetic prose used in stark contrast to the traditional Japanese fiction in the pre-Reformation period. These translations, seen in the light of the present-day readers, were unique in what we might term today ‘foreignizing translation’. Lawrence Venuti in Invisibility of the Translator argues that the ideal of (English) translation has been to conceal itself as a translation, i.e. to present itself as an original text (chap I and passim). In that sense, Futabatei’s translations, scandalously presenting itself as a translation, that is to say, as an alien text, is extremely ‘foreignizing’. (shrink)

The present article is based on a interview with a Japanese experienced caregiver who specializes in patients with amyotrophic lateral sclerosis, which generally leads to the locked-in syndrome. Professional caregivers for ALS patients with ventilator experience two particular temporalities in their practice. First, they must monitor the patient continuously during a seven-hour stay. Because a single problem in the ventilator can have fatal consequences, the care of an ALS patient with a ventilator requires long periods of sustained concentration. Second, trying (...) to understand the signs of a patient with a ventilator sometimes requires three hours to go through ten alphabets. In addition to the huge effort that such communication requires, caregivers must complete the meaning of the signs with their imagination: the ten alphabets are not sufficient to understand what the patient really wants to say. This imaginative capacity, however, is based on a long relationship, which started when the patient was still able to speak and move. That is why, as this article will show, even when a patient has entered total LIS, the caregiver can continue to realize his or her wishes. (shrink)

Do people tend to disagree over political issues because of conflicting values? Or do they disagree about which policies will most effectively promote shared values? In a previous article, I argued that the issues most people think are most important tend to fall into the latter category. On the issues of greatest importance to the mass public, most citizens agree about the ends that are desirable, but disagree about which policy means would best effectuate those ends. Consequently, disputes about facts—disputes (...) about the actual effects of proposed public policies—lie at the heart of the most important divisions in contemporary American public opinion. However, people do not necessarily interpret their political disagreements this way. If they fail to recognize that facts that they see as self-evident are disputed by their opponents, they may see their opponents as having different values, since there could be few other explanations for their opponents' disagreement with them. However, evidence that disagreements about facts are really driving public opinion can be found by using conditional surveys, which ask respondents if they would support a given policy if they believed that it would cause specific negative consequences.
