How much do you bid? Answers from ChatGPT in first-price and second-price auctions

This research examines the feasibility of using ChatGPT as a subject in an auction experiment. The author will also test the idea of giving ChatGPT a “persona” to participate as a human. Without personas, the author finds overbidding in the FPA and slight underbidding in the SPA; the FPA results are consistent with prior studies, but the SPA results differ. Given the persona as an excellent economics student, ChatGPT bid close to the theoretical prediction in the FPA but significantly underbid in the SPA. These results raise questions about using LLM-based AI subjects in auctions.

Decision making under virtual environment triggers more aggressive tactical solutions

Virtual reality is a promising technology that can be used to assess and train decision-making skills in sports. However, it is not necessarily clear what benefits this technology offers compared to previous technologies. The present study investigated the differences in option generation related to tactical decision-making when the same tactical scene was observed in 2D video and 3D VR. Soccer players (N = 27) were asked to observe tactical scenes and verbally report as many tactical options as possible under 2D video and 3D VR conditions. They were classified into high-, medium-, or low-decision capability groups based on the decision-making test. Irrespective of the capability, the 2D video and 3D VR had the same number of generated options. However, 3D VR generated more aggressive options that led to the goal, even though the exact same scene was observed between the conditions. This result may be because 3D VR can reproduce more realistic information exploration behavior than 2D video. Given that differences were observed regardless of skill level, the results suggest that VR technology has the potential for use as a more accurate decision evaluation method and effective training tool compared to previous methods for a wide variety of learners.

Possibility of regional revitalization by students’ IT

Recently, the number of students who can develop applications that can actually be used has increased. We thought that this power could be used for regional revitalization, we tried to connect the students and the region. As a result, we were able to create some interesting applications, some of which have become widely used in practice. For students, before going out to society, they can work on practical application development and know what kind of ingenuity is necessary to get them to actually use it. Although quality is not necessarily guaranteed in rural areas, the possibility of using the latest AI technology at a short development time and at a low cost was shown.

Changing weight perception using augmented reality

Augmented reality (AR) is a technology that renders computer-generated (CG) images onto the physical world in real time. To establish technology to alter weight perception using CG images in an AR environment, we investigated whether the size of virtual objects superimposed on a physical object would affect perceived heaviness. Participants (n = 22) wore a head-mounted display with a stereo camera and observed an object overlaid with a CG image. They lifted the object vertically and rated its subjective heaviness. We found that the virtually smaller object was perceived to be heavier than the virtually larger object among a large share of participants, indicating that a well-known phenomenon, the size-weight illusion (SWI), occurred. The SWI did not occur when the virtual size became larger or smaller after movement to reach the object was initiated. Our results suggest that presenting virtual objects in an AR environment effectively altered weight perception.

The Effect of Auditory Stimulation on College Sports Team and University Identification of Media Spectators: Focusing on the Presence or Absence of Live Play-by-Play Announcements and Commentary

This study aimed to determine how college sports team identifications and university identifications of college sports media viewers differ depending on the presence or absence of live play-by-play announcements and commentary. The participants in the experiment were 115 students from University A. A screening survey was conducted to confirm that these were essential attributes, resulting in 58 and 57 participants in the groups with commentary and without commentary, respectively. We conducted an Internet survey with these two groups of experimental participants before and after watching videos of the games. The results showed that only the group with commentary demonstrated improvements in the "public evaluation" of the college sports team and university identification (College sports team: F (1, 113) = 5.28, p < .05; University: F (1, 113) = 5.28, p < .05).

Nature Versus Artifact Body II:Sollen, Central Dualism, and Chameleon Criteria

Contrary to Wiener’s work, the subject of Sein and Sollen in “nature versus artifact bodies” was logically re-examined using a white-box (pair-matrix) approach and formalized on pair-map (microcosm) under closed-earth versus smart-world conditions. This body science and Sollen of 3M&I variety (pair-map) would be probably developed at the type of ternary SW, which resembles the Eastern danshari concept, and is likely due to the motion–energy dualism under Newton’s laws (analog type), or equivalently, the amount–value dualism under Matsui’s law and dualism (discrete type). For this body’s central dualism, a pair map (rotational phase) was characterized in 1983 based on the microcosm of cross-ellipse images in a matrix of input–output pairs. At the paper, this field theory is physically formulated, solving the pair matrix, ternary SW and its central dynamism in a body of input-output. The observed underlying condensed structure (time model), and the internalized (embedded) dynamism (fractal and wave motion equations), are numerically clarified based on the expansion of the corporate-producing entity pair maps in Matsui’s theory. Furthermore, it is demonstrated that the center of the pair-map hyperplane corresponds to a black hole (manifesting in the form of a conical dip that warps spacetime), collapsing the artifact bodies. Finally, interesting issues and findings are reported regarding the central dualism, progressive physics and chameleon criteria (medium), and are related to pair-map.

Creating a scale for measuring non-cognitive abilities developed through sports for elementary school students

The purpose of this study was to create a scale to measure non-cognitive skills that can be developed through sport. To begin, a draft of a non-cognitive ability measurement scale was developed based on previous research. A preliminary survey of 346 elementary school students (318 males and 28 females, mean age 8.90 ± 1.76 years) was conducted, and a preliminary scale was created using exploratory factor analysis. A subsequent main survey was conducted with 1171 elementary school students (1025 males and 146 females, mean age 8.77 ± 1.73). In the present study, confirmatory factor analysis, reliability testing using cronbach's alpha, and structural validity of the entire scale were examined using structural analysis of covariance. Furthermore, theoretical interpretations were also taken into account, and finally, a non-cognitive ability measurement scale that can be developed through sports for elementary school students was created, consisting of 50 items with 5 factors: "self-management," "problem-solving," "cooperativeness," "leadership," and "greetings/polite".

A statistical examination into the structure of plays and its relationship to wins/losses in basketball games played by excellent players from the standpoint of STATS

We reviewed and summarized the findings from some kinds of perspectives. This allowed us to realize that no consistent findings can be obtained in terms of what plays/factors contribute most to wins/losses and the sequence of plays leading to scoring, that discriminant analysis is commonly used in the studies, and that for structural analysis, no rotational technique was used. Based on these findings, we devised the following new proposals: 1) Researchers need to exert more effort to analyze various kinds of games in the future, 2) We can recommend logistic regression analysis, but not only discrimination analysis. 3) For structural analysis, to make the research findings useful, the rotation of axes or principal components should be actively utilized.

Development of Japanese women professional soccer athletes’ second career training

The purpose of this study was to describe, explain, and recommend how women’s professional soccer players and clubs could prepare for second career transitions in a way that minimizes psychosocial crises upon retirement. The Japan Women’s Empowerment Professional Football League (called the WE league) was founded with a mission to contribute towards building a sustainable society through promoting female social participation and enhancing diversity and choice. This study suggested training strategies that could foster second career development in the WE league. These strategies are (a) including theoretical frameworks in second career pathways, (b) the necessity of dual education pathways for Japanese women’s professional athletes, (c) promoting virtual internship experiences for Japanese women’s professional athletes, and (d) recommendations of second career training workshops for professional athletes in the WE League. The WE League and teams should allow professional athletes to improve meaningful skills and knowledge development, multiple experiential learning opportunities, and applicable training on second career development. Due to the paucity of research in this area, it is essential for scholars to further explore potential education and internships opportunities to ease transitions to second careers upon retirement.

Proposal of Rubric for Information Security Education Materials

This study proposes a generic rubric that can be used as an assessment axis for information security educational materials regarding existing computer science education evaluation standards to assess the learning effectiveness of information security educational materials aimed at young people. The proposed rubric includes items such as “understanding of cyber security” and “understanding why passwords are necessary,” and five-level learning objectives are defined for these items. Furthermore, the proposed rubric was used to assess the existing information security educational material “Hajimete no Joho Security (Learning First Information Security in a Different World)” using Minecraft. The proposed rubric was mapped to the learning contents of the teaching material as an assessment method, and the learning effectiveness of the teaching material was measured using Minecraft with the cooperation of a community center project in Sayama City in Japan. Therefore, we were able to evaluate the learning effects using the proposed rubric.
