Effective Theory Approach to the Skyrme model and Application to Pentaquarks

The Skyrme model is reconsidered from an effective theory point of view. From the most general chiral Lagrangian up to including terms of order $p^4$, $N_c$ and $\delta m^2$ ($\delta m\equiv m_s-m$), new interactions, which have never been considered before, appear upon collective coordinate quantization. We obtain the parameter set best fitted to the observed low-lying baryon masses, by performing the second order perturbative calculations with respect to $\delta m$. We calculate the masses and the decay widths of the other members of (mainly) anti-decuplet pentaquark states. The formula for the decay widths is reconsidered and its baryon mass dependence is clarified.Comment: 65 pages, 1 figure.

A Fast Implementation of ηT\eta_T Pairing in Characteristic Three on Intel Core 2 Duo Processor

We present an efficient implementation of $\eta_T$ pairing on Intel Core 2 Duo processor. The processing speed of our implementation achieves 92 $\mu$sec over ${\mathbb F}_3^{97}$ and 553 $\mu$sec over ${\mathbb F}_3^{193}$ on 2.6GHz processor

The Psychological Ownership of Ethnobotanicals through Education

A qualitative research case study was conducted over two summers with caretakers and children. The aim was studying how ethnobotanical content-based environmental education (EE) in English classes can impact psychological ownership (PO) of plants. The objectives were to study reactions to classroom scenarios. Subjects were selected through purposive sampling, and data through notes, observation, and recording. The second summer, a questionnaire was integrated into the lesson. Results showed that caretakers hinder children’s enthusiasm about disliked plants. However, they also change their perspectives with EE. Impact on PO increased from traditional teacher-centered lessons, more with crafts, and the most with ingestion. eISSN: 2398-4287 © 2018.

A computational model based on corticospinal functional MRI revealed asymmetrically organized motor corticospinal networks in humans

新規MRI技術で利き手の神経制御メカニズムを解明 --手指運動中の脳・脊髄機能結合パターンの左右差を世界で初めて計測--. 京都大学プレスリリース. 2022-08-08.Evolution of the direct, monosynaptic connection from the primary motor cortex to the spinal cord parallels acquisition of hand dexterity and lateralization of hand preference. In non-human mammals, the indirect, multi-synaptic connections between the bilateral primary motor cortices and the spinal cord also participates in controlling dexterous hand movement. However, it remains unknown how the direct and indirect corticospinal pathways work in concert to control unilateral hand movement with lateralized preference in humans. Here we demonstrated the asymmetric functional organization of the two corticospinal networks, by combining network modelling and simultaneous functional magnetic resonance imaging techniques of the brain and the spinal cord. Moreover, we also found that the degree of the involvement of the two corticospinal networks paralleled lateralization of hand preference. The present results pointed to the functionally lateralized motor nervous system that underlies the behavioral asymmetry of handedness in humans

Global Education at Australian Universities

In this paper, we examine several practices of global education at Australian universities and, thereby, identify their characteristics and challenges in order to derive implications for higher education in Japan. We visited four universities in Australia, i.e. the University of Wollongong, the University of Melbourne, Monash University, and La Trobe University, and conducted interviews with academic as well as administrative staff in charge of global education or studies abroad. The universities we visited understood that the institutional transformation of educational systems was a necessary prerequisite for globalization of university education. In the implementation of institutional transformations, initiatives undertaken by a university-wide organization, the involvement of faculty members through workshops and group discussions, and careful implementation considering potential tensions between “research” and “education” were confirmed. With regard to the actual contents of global education, the cases we examined strongly emphasized the practical application of learned knowledge or skills, to be acquired through interactions with real society, to global issues. It was clearly recognized that a major role of universities is to help students acquire such competencies for the practical application of knowledge, with an emphasis on the processes through which students recognize that they can – and should – apply learned knowledge to global problems for solutions. We confirmed that the practices of Australian global education, which refer to “inner multicultural situations” and strive to foster global citizenship contributing to solutions of global problems, have many implications for Japanese universities

NEW ANALYSIS OF VISUALIZATION IN EDUINFORMATICS USING A NETWORK WITH PARAMETRIC AND NONPARAMETRIC CORRELATION COEFFICIENTS WITH THRESHOLD

Eduinformatics, a new term coined by us, is a field that combines education and informatics, and novel techniques will need to be developed for this field. Earlier, we developed a new visualization method to visualize the curriculum of Kobe Tokiwa University using multidimensional scaling (MDS) and a scatter plot. In this study, our focus is on methods to analyze the relationships between answers to questions in eduinformatics questionnaires. MDS methods are very useful, but have limitations in that their results are difficult to interpret. To facilitate the interpretation of these results, we develop a new visualization method using a network with both parametric and non-parametric correlation coefficients with a threshold (VNCC). VNCC has nine steps. We apply the VNCC method to research on nursing education, and provide an example of the visualization of the result. VNCC methods will be useful in dealing with qualitative research in eduinformatics
