Positive relationships of character strengths with fitness and physical activity in primary school children.

Objective: This study is the first to examine the relationship between character strengths, objective physical fitness, and physical activity in primary school children.

Design: This cross-sectional study was conducted in 2016 and 2017 at a school in Japan. Main Outcome Measures: We obtained informed consent from 236 fourth-grade students; 122 fifth-grade students; and 142 sixth-grade students.

Facile Surface Modification of MgMnO Positive-Electrode Material for Improving Cycle Performance of Magnesium Rechargeable Batteries.

MgMnO with a tetragonal spinel structure shows promise as a positive-electrode material in magnesium rechargeable batteries (MRBs), which have drawn considerable attention as post lithium-ion batteries. However, the material currently suffers from poor cycle performance. In this study, we attempt to improve the cycle performance of MgMnO via the Zr modification of its particle surface.

In Japan, individuals of higher social class engage in other-oriented humor.

Previous research on individual social class (SC) and humor has found support for the hypothesis that those with higher SC will engage in more dominant humor (aggressive humor) that derogates or degrades others. One rationale for introducing this hypothesis is the well-known theory that people with higher SC are more self-oriented; however, it has recently been shown that there may be cultural differences in this theory. In this study, using a Japanese sample objective measures (income and educational attainment) and subjective measures (perceived social status) and examined in relation to humor.

Students' Perception of Teachers' Humor Predicts Their Mental Health.

The aim of the present study was to determine whether two types of teacher humor (Aggressive Humor and Affinity Humor) are predictors of students' mental health. A self-report scale was administered to 500 elementary and junior high school students in grades 4 to 9 (mean age 12.04, SD = 1.

Preliminary Verification of Instructional Humor Processing Theory: Mediators Between Instructor Humor and Student Learning.

Instructional humor processing theory has been proposed to explain how the type of humor used by the course instructor can affect student learning. In this study, a cross-sectional design was used to test whether the relation between the instructor's type of humor (related, unrelated, self-disparaging, offensive, and disparaging humor), and learning is mediated by variables assumed by the instructional humor processing theory (emotion, motivation, and information-processing ability). A total of 360 university and junior college students with a mean age of 19.

[Construction of the Time Management Scale and examination of the influence of time management on psychological stress response].

We developed a scale to measure time management and assessed its reliability and validity. We then used this scale to examine the impact of time management on psychological stress response. In Study 1-1, we developed the scale and assessed its internal consistency and criterion-related validity.

[Character strengths and well-being in Japanese children and youth: creating good habits].

Character education in the US aims to establish good habits corresponding to good character. The purpose of this study was to determine the structure of character strengths and the relations among these strengths and wellbeing in Japanese children and youth. Peterson and Seligman (2004) developed a classification of character strengths called VIA-IS.
