Proposal of a Haiku Evaluation Method Using Large Language Model and Prompt Engineering

2025-01-20T05:55:02+00:00

In this paper we describe the development of a haiku evaluation system using Large Language Model (LLM). We propose several prompting methods for haiku evaluation and selection, and verify the performance of the proposed methods using an automatically evaluable haiku dataset. We also performed haiku evaluation and selection on a large haiku database containing over 100 million verses using the proposed methods and validated their effectiveness through a questionnaire survey of haiku poets. The main contributions of this paper are as follows. First, we investigated the effectiveness of the procedures for demonstrating the validity of a number of haiku rating systems, including the creation of rating datasets and the results of subjective ratings through questionnaires. Second, we investigated methods for conducting haiku evaluation using LLM and prompt engineering.

The Role of Sustainable Management for Two-sided Platform Competition

2025-05-30T05:04:37+00:00

This study develops a theoretical framework to analyze investment for corporate social responsibility (CSR) activities in competing two-sided platforms. Building on previous research, we model two platfors, a platform with CSR and without CSR, where consumers and providers choose platforms based on utilities that network externalities, valuation for CSR, and regulatory costs. Agent personality is captured by assuming CSR valuations and regulation loss sensitivities follow uniform distributions. We derive closed form equilibrium numbers of consumers and providers and equilibrium prices under quadratic CSR costs and probabilistic violation losses. Numerical analysis with calibrated parameters from prior literature shows that higher CSR investment raises expected profits, participant numbers of consumers, and equilibrium prices for both platforms, platform with CSR consistently outperforming its without CSR counterpart. The results demonstrate that CSR investment as a sustainable management functions both as a strategic tool for customer acquisition leveraging enhanced network externalities and as an effective risk management mechanism by reducing expected violation losses. Moderate CSR investment thus yields competitive advantages, suggesting platform managers should integrate CSR considerations into early design and pricing strategies. The model also highlights trade offs between investment costs and network benefits, providing a basis for optimizing CSR levels under varying market conditions. Future work will empirically calibrate key parameters to validate and refine these theoretical insights.

The Influence of Visual Elements and Color Sensitivity on Product Image Selection

2025-05-25T13:12:04+00:00

This study investigates how visual elements of product images on online flea market platforms influence impression formation and purchasing decisions. As online flea markets grow with diverse user demographics, individual sellers often struggle to effectively present products due to a lack of standardized guidelines. While anonymous transactions and flexible image settings attract users, inconsistent presentation quality impacts sales success. Visual elements like exposure, contrast, saturation, color temperature, and sharpness are crucial in conveying product appeal, yet their effects remain underexplored. Particularly, how these factors influence quick impression formation is not well understood. This study experimentally examines these visual parameters to clarify their impact on purchasing motivation. The findings aim to provide evidence-based guidelines to enhance product presentation, ultimately improving sales outcomes for both new and struggling sellers on online flea market platforms.

Awareness Changes in Participants in Online Symposiums — Observations from Pre- and Post-Questionnaire Survey Results

2025-05-30T19:51:09+00:00

This study aims to clarify the changes in participants’ awareness of an online symposium on MICE held during the COVID-19 pandemic. Authors compared and analyzed the results of a questionnaire survey conducted before and after the symposium targeting practitioners involved in attracting international conferences. The analysis showed that post-symposium evaluations increased in areas such as networking, understanding of infectious disease countermeasures, and interest in local resources, indicating that the symposium contributed to raising participants’ awareness. On the other hand, evaluations of VR and AI technologies settled at a realistic level due to an understanding of their limitations. Concerns about the decrease in international conferences were also somewhat alleviated by the prospect of a future recovery. In addition, discriminant analysis showed that the correct answer rate for the classification of pre- and post-symposium responses was 96.7%, confirming a clear change in participants’ awareness. This study provides suggestions for the form of international conferences and strategic information provision in the post-COVID era.

The Interaction Between Entrepreneurial Characteristics and Ecosystems in Japan

2025-01-10T14:35:42+00:00

The purpose of this paper is to explore the relationship between entrepreneurial behavior characteristics and the entrepreneurial ecosystem (hereafter referred to as EE) in Japan and to develop a new model of entrepreneurial characteristics (hereafter referred to as the EC model). The entrepreneurs activity in Japan remains persistently low, contributing to prolonged economic stagnation and limited innovation. While traditional studies have focused on the internal factors of entrepreneurs, recently the importance of EE, an external factor in entrepreneurship, has been pointed out. In this study, we integrate the internal factor, entrepreneur, and the external factor, EE, and construct the EC model that does not exist in previous models, which takes into account their interaction. Through interviews, we aim to explore the interaction between entrepreneurs' internal and external factors and deepen our understanding of EE's impact in Japan via the EC model. The results of this study are expected to highlight the real needs and challenges of entrepreneurs and contribute to the development of entrepreneurship.

Development of a Value Recognition Method for Working Mothers to Balance Work and Childcare based on Their Sense of Authenticity

2025-05-30T14:23:33+00:00

This study proposes and evaluates a psychological coping method that increases the sense of authenticity of working mothers. The number of working mothers is increasing as women’s participation in the workforce has increased considerably. However, working mothers experience conflicts between balancing work and childcare. They can continue working because they can engage in in psychological self-care and overcome the dilemma of balancing work and childcare through physical resources and support. Therefore, it is important for working mothers to integrate their identities as workers and mothers. Our proposed method helps working mothers feel that they can achieve both career development and childcare that relates to their authentic selves and assuages conflicts arising from creating a balance between them. In the proposed method, working mothers reflect on their past and identify the value of work and childcare. The goal is to determine common values for mothers and help them recognize that both work and childcare can coexist, fulfilling their own personalities. We conducted a control experiment with 23 working mothers, in which the proposed method and an existing method were implemented. The effectiveness and validity were compared and evaluated by analyzing questionnaires before and after the experiment. The findings revealed that the proposed method was highly effective regarding the sense of authenticity and work–family enrichment. In addition, working mothers experienced that they could balance career and childcare, which related to their authentic selves, and were more likely to use the proposed method than the existing method. Our proposed method is a psychological coping method that enables working mothers to recognize the common value of work and childcare, realize their identity, and raise their sense of authenticity.

A Case Study on Strategic Digital Transformation in Traditional Manufacturing

2025-05-25T07:03:17+00:00

The present study conducts a longitudinal single-case analysis guided by Resource-Based Theory (RBT), Dynamic Capabilities, and Organizational Learning Theory to investigate the strategic digital transformation (DT) of a traditional Taiwanese manufacturing firm. The research examines how the phased integration of ERP systems, real-time data platforms, and AI-driven decision support tools has facilitated improvements in operational efficiency, managerial competencies, and environmental sustainability. A multi-source methodology was employed, comprising structured interviews, expert panel evaluations, and organizational performance metrics. This methodology was applied across three stages of transformation: digitization, optimization, and transformation. The findings indicate significant advancements in processing efficiency, profit margins, and the development of managerial aptitude. Additionally, the transition to electronic documentation has nearly eliminated the use of paper. The study further identifies organizational learning cycles and adaptive capabilities as key enablers in overcoming internal resistance and technological inertia. This work makes a notable contribution to the existing DT literature by integrating strategic capability-building frameworks with practical implementation insights. It provides a contextualized model for transformation in resource-constrained traditional industries.

From Strangers to Community Builders

2025-05-30T13:36:13+00:00

This study aims to clarify the impact that volunteer events managed by university students from outside the region have on interactions with local residents and tourism promotion. Using the "Hirose River Utilization Promotion Project" implemented in Maebashi City, Gunma Prefecture in 2025 as a case study, analysis was conducted through interviews with six participants. As a result, the extraordinary spatial experience and active involvement of students were highly evaluated, and it was confirmed that they would increase their motivation to participate in the community in the future. In particular, the planning and management by university students brought new perspectives and vitality to the area and was favorably received by local residents. It was suggested that collaboration between universities and communities has the potential to encourage a reevaluation of local resources and a change in resident awareness.

A Study on the Key Factors for the Success in Evaluating Fast Fashion Enterprises’ Brand Value Based on ESG

2025-05-29T03:59:56+00:00

In the rapid development of the fast fashion industry, consumers benefit from low prices, up-to-date fashion trends, and diverse styles. However, this industry model also presents significant challenges in terms of environmental, social, and corporate governance (ESG). Issues such as the depletion of natural resources, water pollution, child labor, low wages, cost pressures, and kickbacks in corporate governance have drawn widespread attention. Therefore, this study employs the Analytic Hierarchy Process (AHP) to explore the key indicators of ESG implementation in fast fashion companies, evaluating them across the three major dimensions of environment, society, and corporate governance. This study highlights that the core of sustainable development for enterprises should focus on carbon emission management, actively promoting reduction measures to minimize environmental impact. This strategy not only complies with global environmental regulations but also enhances the company’s competitiveness, strengthens the brand’s green image, and attracts environmentally-conscious consumers, fostering brand loyalty.

A Regional Digital Transformation System for Enhancing Local Vegetable Supply in School Lunches

2025-05-24T10:06:14+00:00

This paper introduces the development and implementation of a digital transformation (Agri-DX) system aimed at enhancing the use of locally produced vegetables in school lunches in a Japanese regional city. Initiated in 2021 through a university-municipality collaboration, the system facilitates six-month menu-based planning, integrates cultivation and shipment scheduling, and enables real-time data sharing among producers, agricultural cooperatives (JA), and school lunch centers. The system’s cloud-based architecture improves transparency, optimizes supply chains, and enhances food education and sustainability. Results show a significant improvement in local sourcing rates, aiming from 16.3% in FY2022 to 44.6% by FY2029. This study demonstrates how structured information systems can address food security, economic stability, and regional revitalization.

Interorganizational Relationships and Structural Changes in Traditional Craft Production Areas

2025-05-30T08:08:44+00:00

The aim of this study is to analyze the interorganizational relationships that manufacturers in traditional craft production areas, which are in the declining phase of their life cycle but still survive, have established, and to clarify the decisions made by manufacturers in traditional craft production areas to survive. This study examined the Oshima-Tsumugi textile production area in Kagoshima, Japan. The results of the case analysis revealed that the decision-making process for establishing interorganizational relationships among textile manufacturers is implicitly influenced by wholesalers’ intentions. Textile manufacturers seek to survive by developing distribution channels outside wholesalers and by consolidating managerial resources through vertical integration among textile manufacturers. A new finding of this study is that, in the late decline phase, competing textile manufacturers aimed to develop horizontal cooperative relationships.

Differential Peer Influence in Japanese Lotteries

2025-05-26T06:15:37+00:00

All lotteries sold in Japan are national lotteries and the proceeds from these are utilized for socially beneficial projects. However, lotteries constitute a form of gambling and research has demonstrated that the purchase of lottery tickets by acquaintances and family members influences them. This study investigated the influence of others on lottery purchases in Japan. Data were obtained through a questionnaire survey, and statistical analysis revealed that the consumption of lotteries with short intervals between draws, such as scratch-off lottery tickets and internet lotteries, Numbers 3 and Numbers 4, was correlated with social networks. Conversely, there was a limited correlation between social networking and the consumption of lotteries with high first-prize money, such as Jumbo, Lotto 6, and Lotto 7, but long intervals between draws. This research provides implications not only for lottery consumption decision-making, but also for lottery policy implementation.

Validating the Factor Structure of Acceptance in Practical Decision-Making

2025-05-31T08:26:49+00:00

This study aims to validate a three-factor model of psychological acceptance in practical decision-making using confirmatory factor analysis (CFA). In complex real-world contexts, individuals’ sense of acceptance—characterized by cognitive clarity, emotional reassurance, and volitional commitment—plays a critical role in decision quality and implementation. Existing tools like the GDMS and DCS scales fail to fully capture this multidimensional construct. Based on previous exploratory factor analysis (EFA), the authors developed a 30-item scale measuring three latent factors: Deeper Understanding, Emotional Acceptance, and Subjective Recognition. CFA was conducted with 611 working adults, and the model showed good fit indices (CFI = 0.928, RMSEA = 0.061, etc.), with strong factor loadings and reliability. The findings confirm that psychological acceptance can be measured as a structured construct that complements traditional decision-making frameworks. This model offers practical implications for designing decision support systems and evaluating participatory decision-making. It also extends prior research in healthcare to broader organizational settings.

Value Design Method for Digital Innovation

2025-01-20T21:59:02+00:00

With the evolution of digital technologies such as IoT (Internet of Things) and AI (Artificial Intelligence), opportunities for digital innovation are expanding for all companies, including small and medium-sized enterprises and non-IT companies. However, while many companies can engage in “defensive digital transformation (DX)” by using digital technologies to improve their daily operations, achieving “offensive DX” to create new value in products and services through digital technologies is not easy. We have been developing the “Digital Innovation Design Method” to support offensive DX. This paper presents a new method to further concretize the “value design” of Digital Innovation Design Method. Specifically, while the original value design used the Value Proposition Canvas, the Value Proposition Canvas is generic and difficult for companies unfamiliar with digital technologies to utilize for offensive DX. The method proposed in this paper supports value design considering the characteristics of digital innovation utilizing “Value Graph” and “Digital Value Patterns” in addition to “Value Proposition Canvas” and evaluates its effectiveness through a descriptive experiment with 32 participants.

Unlocking Entrepreneurial Potential: Connection to Creation through a Visualizing Method for Enhancing Women’s Business Networks in Tourism

2025-05-30T07:06:37+00:00

This study proposes a novel descriptive method, “Entrepreneurial Networks – Stakeholder Value Creation Mapping” (EN-SVCM) to support women entrepreneurs in the tourism sector of developing countries. Although business networks are widely acknowledged as critical to entrepreneurial success, many women face persistent social and structural challenges in accessing and leveraging such networks. The EN-SVCM method delineated in this paper integrates existing frameworks and tools to visualize current business networks, identify value exchanges, and strategically expand stakeholder connections. A pilot workshop in Uzbekistan was conducted with six women entrepreneurs to validate the method. Participants visualized their networks, conceptualized new experiential tourism services, and refined ideas through peer learning. Findings support the method’s effectiveness and potential to strengthen entrepreneurial capabilities, enhance network awareness and expansion, uncovering growth opportunities, and enhancing network-based ideation. The EN-SVCM method offers a practical, adaptable tool for empowering women entrepreneurs by improving networks, stakeholder engagement and fostering inclusive, sustainable entrepreneurship in tourism.

A Study on the Key Factors Influencing Consumers' Adoption of NFT Application Services from the Perspective of PPM Framework

2025-05-25T13:39:06+00:00

As blockchain and digital assets evolve, NFT services are gaining prominence. This study applies the Push–Pull–Mooring (PPM) framework to examine factors influencing consumer adoption of NFT applications. Based on 574 responses from Taiwanese users, results show that push and pull factors boost adoption intent, especially pull factors, while switching costs hinder it. The findings validate PPM’s relevance in digital services and offer practical strategies to enhance NFT adoption by improving usability, reducing barriers, and fostering community value. The study confirms the relevance of the PPM model in digital service adoption and addresses a research gap in the Asian NFT context. Practical suggestions include improving platform usability, strengthening community value, and reducing adoption barriers to drive NFT growth.

Exploring Pre-Senior Decision-Making Styles Using the Qualitative Synthesis Method

2025-05-31T03:57:16+00:00

Japan's population is ageing rapidly, with increasing opportunities for older people to make decisions in all aspects of society, including healthcare, long-term care and the working environment, and there is a need to clarify what factors influence decision-making by older people. Research on decision-making styles in adolescents has revealed the coexistence of rational and maladaptive styles, and the tendency for decision-making styles to differ across developmental stages. Previous studies of older people have mainly focused on those aged 65 and over, with little attention paid to the decision-making processes of the previous generation, from the ages of 50 to 65. Therefore, with the aim of clarifying the decision-making characteristics of the ‘reserve group’ in the intermediate area between old age and adolescence, this study analyses interviews with the reserve group using a qualitative synthesis method.

The Influence of Body Usage on Creative Drawing: A Comparison of Calisthenics and Meditation in Junior High School Students

2025-01-14T16:13:50+00:00

This study investigates the influence of body usage on creativity drawing. We examined the effects of physical exercise and meditation on creativity in second-year junior high school students (N=97) through a within-subjects experiment. Participants performed three-minute sessions of calisthenics and meditation before drawing, and their artworks were analyzed for differences in area, color usage, and the presence of warm/cold colors. The results showed that 1) drawings after meditation tended to have larger areas, while those after calisthenics showed an increased use of warm colors; 2) In the questionnaire, the students who felt that calisthenics activated their creative drawing often commented on body image, while other students who felt that meditation activated them commented on thinking and feeling.

Proposal of a One-on-One Meeting Program to Enhance the Sense of Self-Usefulness Among Residential Care Workers at a Children's Home

2025-05-30T00:46:12+00:00

This study focuses on enhancing the subjective well-being of residential care workers at a children’s home by enhancing their sense of self-usefulness and self-acceptance. A prototype of a one-on-one meeting program was developed and its effectiveness was examined. The program consists of two components: an introductory interview that encourages reflection on work experiences and a one-on-one session using photographs of children to enhance self-usefulness and self-acceptance. The program was implemented with eight residential care workers at a children’s home, and both quantitative assessments using psychological scales and qualitative evaluations through semi-structured interviews were conducted. The findings suggest that the program demonstrated preliminary effectiveness in enhancing sense of self-usefulness, self-acceptance, self-efficacy, and psychological well-being.

A Study on a New Framework for the Influence of Time Constraints on Decision Making

2025-05-25T13:07:48+00:00

This study examines a new analytical framework for the concept of time as it affects decision making. Here, we consider what generates time pressure to be time constraints and problem difficulty, and propose a framework for analyzing pressure situations based on a combination of these two factors. A preliminary small-scale experiment was conducted to test the validity of this framework.

Toward a Quantitative Validation of Entrepreneurial Characteristics and Ecosystem in Japan

2025-05-30T13:58:35+00:00

This study aims to quantitatively validate the Entrepreneurial Characteristics (EC) Model, which conceptualizes the interaction between internal factors (mindset and skillset) and external factors (entrepreneurial support systems and cultural context) in the decision-making of Japanese entrepreneurs. Based on prior qualitative research, we developed a scale reflecting these dimensions and conducted a pilot survey with 106 participants. Using exploratory factor analysis (EFA) with maximum likelihood estimation and promax rotation, we identified a three-factor structure: (1) Environmental Readiness, (2) Entrepreneurial Drive, and (3) Sense of Purpose. These factors reflect key dimensions of the EC model and demonstrate theoretical coherence and practical relevance. The findings offer a foundational framework for subsequent confirmatory factor analysis (CFA) and structural equation modeling (SEM), contributing to both academic theory and entrepreneurial support policy. This study serves as a bridge between qualitative insights and empirical validation, offering new directions for entrepreneurship research in Japan.

Business Professionals' Acceptance of Ikebana

2024-12-20T11:58:21+00:00

Mindfulness, a type of mental training, is gaining attention among business professionals. This study explored the potential of ikebana as a form of mindfulness practice. Further, it sought to elucidate how ikebana is integrated into personal and business settings. To achieve this, semi-structured interviews were conducted with business professionals experienced in ikebana, guided by two research questions. Consequently, we confirmed that participants’ words regarding their personal lives, business, and self-perception are relatied to the ikebana. Additionally, participants noted that ikebana can be a mood-changer in everyday life and promote self-awareness and awareness of others in business contexts.

The Attribute Framing Effects That Influence DecisionMaking Are Altered by Gestures

2025-05-29T08:13:07+00:00

People make satisfying decisions based on biased choices. The attribute framing effect is a type of cognitive bias in which logically equivalent but different verbal expressions influence decision making. Most studies of the attribute framing effect to date have clarified which verbal expres-sions cause framing bias in decision making. However, it has not been determined whether the attribute framing effects occur even when a gesture is presented with verbal expressions or only when only verbal expressions are presented. We conducted experiments to investigate how ges-tural stimuli affect the attribute framing effect. As a result, we found that the attribute framing effect occurs, but is reduced, when a gesture expressing quantitative information is presented with a verbal expression compared to when only a verbal expression is presented. Our findings make a practical contribution to the research on the attribute framing effects by providing insight into the extent to which the attribute framing effects occur when people view nonverbal infor-mation alongside verbal expressions.

Digital Transformation in Japan’s Accommodation Sector

2025-05-25T00:48:08+00:00

This study examines the potential of digital transformation (DX) in Japan’s accommodation industry through a case study of TAP Hospitality Lab Okinawa (THL), an experimental facility established in 2023. THL exemplifies a modular and stakeholder-integrated approach, combining advanced technologies with multi-sector collaboration. Drawing on insights from an on-site investigation and SWOT analysis, the findings indicate that THL’s innovations—including smart interfaces, contactless services, and robotic systems—significantly enhance operational efficiency and guest satisfaction. Beyond business innovation, THL advances a comprehensive model of tourism DX by contributing to regional revitalization in Okinawa, tourism development, and the cultivation of domestic and local IT talent. Despite certain constraints, the study positions THL as a viable and scalable testbed for accelerating DX adoption across Japan’s hospitality sector.

Industrial Specific Evaluation for Corporate Social Responsibility

2025-05-30T09:07:48+00:00

This study analyzed the differences in effective Corporate Social Responsibility(CSR) activities across industries among Japanese companies. Using Toyo Keizai CSR data and conducting statistical analysis with a multilevel model, the results revealed that internal CSR activities have a significant impact on CSR evaluations in the chemical industry, while external CSR activities are highly valued in the electrical equipment industry. These findings suggest that the key areas of CSR activities differ depending on industry specific risks and social demands, indicating that companies should develop CSR strategies tailored to the structure of their respective industries.

A Study on Organizational Decision-making from the Perspective of Uncertainty and Ambiguity

2025-05-28T01:37:17+00:00

This study examines the effects of ambiguity and uncertainty on organizational decision-making using an agent-based simulation framework. The model integrates hyperbolic discounting to capture shifts in decision-makers’ preferences from long- to short-term orientations over time. Ambiguity is defined as unclear organizational goals and decision criteria, whereas uncertainty refers to unpredictable environmental changes. The simulation showed that uncertainty strongly reduces decision efficiency, whereas ambiguity degrades decision quality. The results highlight how excessive ambiguity and uncertainty can lead to organizational resource inefficiencies. Specifically, I found that situations with high ambiguity and low uncertainty produced the least resource-efficient outcomes than situations with both high ambiguity and uncertainty. This study emphasizes the need to design decision processes that consider environmental complexity and recommends further empirical validation.

Correlation between Learning Motivation and Realization among Working Students, and the Factors

2025-06-01T15:11:36+00:00

This study examined the relationship between the learning motivation of working students and the achievement of learning outcomes through hypothesis-testing correlation analysis. While previous studies by Ikemizu et al. (2025) were limited to identifying average trends, this study focused on the relationship between individual motivation and outcomes. Using data from an Intage survey, hypotheses were set and tested regarding knowledge acquisition, qualification attainment, and the formation of human networks. The results showed that broad knowledge acquisition was achieved as expected, while time constraints had an impact on degree and qualification attainment. These findings provide insights into strategies for supporting continuous learning in adult education.

A Novel Balanced Reporting Innovation with Data Governance Evolution (BRIDGE) Method

2025-01-26T09:36:41+00:00

The era of Society 5.0 demands both creativity and systematic knowledge implementation in organizational settings. However, there exists a significant gap between understanding new knowledge and its practical application. This paper proposes the Balanced Reporting Innovation with Data Governance Evolution (BRIDGE) method as a novel approach to facilitate the transition from intellectual understanding to unconscious competence in implementing new knowledge. Through the lens of Eduinformatics, we demonstrate how the BRIDGE method effectively integrates abductive reasoning for innovation while ensuring organizational acceptance. Using a case study from institutional research practices, we show how the method provides a structured transition period where traditional and innovative approaches coexist, enabling organizations to maintain operational continuity while implementing new methodologies. The BRIDGE method addresses the fundamental challenge of knowledge acceptance by acknowledging that while creativity and abduction are essential for generating new knowledge, successful implementation requires careful consideration of organizational dynamics. Our findings suggest that this method can be adapted for various organizational contexts where new knowledge needs to be effectively implemented and accepted, providing a practical framework for bridging the gap between innovation and adoption.

Mining Online Reviews with Fake Review Detection to Improve Logistics Service Quality

2025-05-30T09:12:08+00:00

This study proposes an analytical framework to identify important information in online reviews and uses the service quality models and relevant literature on logistics service quality to help construct and analyze the logistics service quality topics. First, this study establishes a fake review detection model based on the convolution neural network (CNN) model to remove potential fake reviews. Then, the SERVQUAL and E-S-QUAL models are used to assist in constructing a Latent Dirichlet Allocation (LDA) topic model to identify relevant topics mentioned in the online reviews about logistics service quality. In further data analysis, this study segments the comments, calculates the sentiment scores of the sentences that mention the logistics service quality in the online reviews, and uses the number of helpfulness votes of each online review to calculate the weight of the sentiment score.

Predicting Success Factors of Regional Revitalization Crowdfunding Projects Using Logistic Regression Analysis

2025-05-26T04:34:20+00:00

This study quantitatively identifies desirable words linked to successful purchase-based crowdfunding for regional revitalization. Using 8,544 projects from five Japanese platforms — CAMPFIRE, Booster, ReadyFor, Makuake, and kibidango — we analyzed frequently used words and compared them with non-regional projects to explore differences in success factors. The findings offer insights for developing practical fundraising guidelines.

Proposal of a Method of Learning Strategic Silence to Improve the Effectiveness of Employee Voice

2025-05-31T04:00:06+00:00

Organizations increasingly recognize the importance of utilizing employees’ proactive suggestions to promote innovation. However, in practice, statements that challenge the status quo often carry the risk of negative evaluation from managers, discouraging employees from speaking up. This study focuses on the potential of "strategic silence"—a deliberate choice to withhold voice depending on contextual relevance—as a means of enhancing managerial evaluation. We developed a learning method based on an experiential learning model, incorporating two key functions: the ability to recognize appropriate timing and the ability to self-regulate to avoid excessive silence. A field intervention was conducted to evaluate its effectiveness. Results demonstrated that the method supported the execution of strategic silence and significantly improved employees’ self-efficacy. Whereas the short-term effect on employee voice outcomes was not statistically significant, participants reported an increased belief that strategic silence could enhance the impact of their voice. Notably, those who perceived improvements in the effectiveness of their voice did not experience a reduction in voice behavior, suggesting that strategic silence can be a constructive and empowering strategy, rather than one that suppresses employees from speaking up.
