This article explains the 400 °C and 600 °C rules for forecasting cherry blossom opening using effective accumulated temperature, presents the underlying mathematical model, validates it with a 1997‑2022 Japanese dataset, and discusses how adjusting the critical temperature improves prediction accuracy.
This article examines why couples who frequently display affection on social media may be more prone to break‑ups, presenting a straightforward mathematical model that incorporates social support, psychological expectations, and information diffusion to explain the optimal frequency of public romance.
This article explores how communication theory and the Shannon‑Weaver model can be used to build a quantitative mathematical framework that captures value‑based, interest‑based, and noise‑induced conflicts in interpersonal relationships, offering practical analysis and negotiation guidance.
Using a mathematical model that splits daily output into regular work, overtime, and associated costs, this article shows that while modest overtime can marginally increase productivity, excessive overtime leads to rapidly declining efficiency and rising health, turnover, and creativity costs, ultimately reducing total output.
This article explains the MBTI personality framework, illustrates typical type strengths and weaknesses, and presents practical strategies—including role alignment, communication tuning, customized training, and a basic mathematical model—to enhance overall team performance.
Logical models provide a visual framework linking inputs, activities, outputs, outcomes, and impacts, while mathematical models use equations to quantify relationships; together they enable systematic planning, evaluation, and prediction of complex projects such as school nutrition interventions, enhancing decision‑making across public health and education.
