To clarify factors associated with the effectiveness of motor learning, we examined the association between model-observational skill acquisition and the Autism-Spectrum Quotient (AQ), which is reportedly associated with motor learning via visual information. Twenty healthy adults performed the Kendama task. The participants practiced under three conditions: using their own methods (self), following observation of model actions (model-observation), and following observation of their own actions (self-observation). Measurement trials were performed 20 times prior to self-practice sessions and after each practice session. Success ratios were calculated for each measurement trial. All participants completed the AQ. The difference in success ratios for measurement sessions following practices between the self and model-observation conditions was significantly negatively correlated with AQ scores. Individuals with low AQ values can more easily acquire skills via model-observational motor learning than those with relatively higher AQ values.展开更多

Adversity quotient is the adaptation ability to overcome problems and obstacles with a positive attitude. Early adolescence, as a critical stage of life, needs to cultivate adversity quotient. However, adversity quotient and its influencing factors in adolescents have not been fully understood. Methods: A total of 129 students from 3 junior high schools (grade 7-9) in Chon Buri province, Thailand, were randomly recruited to participate in this correlational research study. They completed 5 questionnaires including the demographic form, adversity quotient assessment, authoritative parenting style, optimism, and rumination. Descriptive statistics and Pearson’s correlation coefficient were used for data analysis. Results: Adversity quotient was at a moderate level with a mean of 138.78 (standard deviation [SD] = 21.25). Adversity quotient was significantly, positively correlated with authoritative parenting at the highest level (r = 0.60), followed by optimism at a moderate level (r = 0.38), and rumination at a low level (r = 0.25, P < 0.01). Conclusions: All parties responsible for early adolescents’ development should enhance the adversity quotient to a higher level through campaigns promoting authoritative parenting and optimism. An unexpected positive correlation between adversity quotient and rumination warrants cautious interpretation and more studies.展开更多

As an application we prove the Liouville theorem depending on Pogorelov type estimates. On the other hand, we obtain the existence and uniqueness of the k-admissible solution for these general equations with the Neumann boundary condition, based on some growth conditions for the right hand function.展开更多
