Easing Foreign Language Anxiety and Creating a Safe Space.
Get PDFForeign Language Anxiety (FLA) is an area of linguistics study that has been studied for a long time. However, relatively little is known about the process of how foreign language learners overcome the negative effects of FLA. To fill this gap, this mixed methods study examined language learners’ changes in FLA and what factors contributed to creating a safe space and helped the students to reduce their FLA over the spring semester of the 2022 academic year. A total of 75 university students participated in this study. Four survey instruments were used: a consent form, Foreign Language Classroom Anxiety Scale (FLCAS) translated into Japanese, a semi-structured interview, and an instructor questionnaire”. A dependent samples t-test revealed that there was no significant difference in students’ FLA between the beginning and end of the mandatory English course. However, a qualitative data analysis suggests that instructors, pair and group work, and dialogue with peers might have played a significant role in helping students to reduce their FLA and create a safe space.departmental bulletin pape
Vision transformers with Inductive Bias introduced through self-attention regularization
Get PDF創価大学博士（工学）In recent years, the Transformer achieved remarkable results in computer vision related tasks, matching, or even surpassing those of convolutional neural networks (CNN). However, unlike CNNs, those vision transformers lack strong inductive biases and, to achieve state-of-the-art results, rely on large architectures and extensive pre-training on tens of millions of images. Introducing the appropriate inductive biases to vision transformers can lead to better convergence and generalization on settings with fewer training data. This work presents a novel way to introduce inductive biases to vision transformers: self-attention regularization. Two different methods of self-attention regularization were devised. Furthermore, this work proposes ARViT, a novel vision transformer architecture, where both self-attention regularization methods are deployed. The experimental results demonstrated that self-attention regularization leads to better convergence and generalization, especially on models pre-trained on mid-size datasets.doctoral thesi

Optimal nutritional modes combination of Chromochloris zofingiensis in multiple cultivation process for biomass and astaxanthin productivity
Get PDF創価大学博士（工学）Chromochloris zofingiensis is an emerging alternative for the commercial production of astaxanthin, to Haematococcus pluvialis, due to its high productivity and ability to grow in multiple nutritional modes namely, autotrophic, mixotrophic and heterotrophic. The cultivation of microalgae in multiple culture steps (stock, preculture, and biomass production phase) in different nutritional modes can contribute to the enhancement of cell biomass and has hardly been performed. Moreover, it’s effect on cell growth and biomass productivity is still unknown. Therefore, in this study, we firstly observed the cell growth in different nutritional modes in preculture phase (Chapter II, Study 1). Later, the effect of preculture on the biomass production via combination of nutritional modes for determining the optimum conditions (stock, preculture and biomass production phase) was evaluated (Chapter III, Study 2). As a result, heterotrophically precultured cells showed higher biomass productivities than with auto- and mixotrophically precultured cells in autotrophic and mixotrophic in biomass production phase. The increase in productivity was due to the stored cellular materials such as lipids, starch and nuclei in heterotrophically precultured cells (Study 2). In the three-phase culture, a highest biomass productivity was obtained in mixotrophic condition (Chapter IV). This study suggested that the optimum combinations of nutritional modes for higher biomass and astaxanthin productivity are autotrophic for stock (to maintain the following heterotrophic growth), heterotrophic for preculture (to store growth-promoting factors), mixotrophic for biomass production phase (to achieve high productivity), and autotrophic (for astaxanthin induction), respectively.doctoral thesi
感謝の意識と表現をめぐる中日の対照研究
Get PDF日本語には、感謝の意識を言葉にする習慣があり、これに関連して「先日はどうもありがとう」と言うような「後日の再感謝」という習慣がある。それに対して、中国ではこれは一般的な習慣にはなっていない。従って、日本人に失礼だと誤解されてしまうという例がしばしばあるようである。そこで、本研究では、日本人、中国人日本語学習者と中国人を対象とし、アンケート調査を行った結果、中日での感謝の意識と表現の相違点が明らかになった。すなわち１.他人に依頼する時、中国人は事前の感謝表現を多く使用するが、日本人は事前の謝罪、依頼の表現を使用する。２.受益の場での感謝について、中国人は感謝の表現より感情の表現を多用するが、日本人は感謝の表現や謝罪の表現を多用する。３.中国人は後日の感情の表現や物に対する評価の表現を多く使用するが、日本人は後日の再感謝をする習慣がある。departmental bulletin pape
道徳科における「心情共感的な学習」と「問題解決的な学習」とを組み合わせることによる効果検証
Get PDF本研究の目的は、道徳科における「心情共感的な学習」と「問題解決的な学習」とを組み合わせることによる効果検証である。そのために、1 つの教材を使って「心情共感的な学習」と「問題解決的な学習」の2 つの授業展開を3 学級で授業実践した。授業実践の前後に道徳的心情と道徳的判断力を問う児童アンケートを行った。次に、3 学級の授業実践やアンケート結果を比較・分析し、共通的特徴と個別的特徴を整理した。そして、「心情共感的な学習」と「問題解決的な学習」とを組み合わせることにより、児童の道徳的価値の理解や思考の変容、自分事としての価値観の形成について特徴を見いだすことができた。departmental bulletin pape
