Distribution of the product of a pair of independent two-sided power variates

ABSTRACT

The distributions of algebraic functions of random variables are important in theory of probability and statistics and other areas such as engineering, reliability, and actuarial applications, and many results based on various distributions are available in the literature. The two-sided power distribution is defined on a bounded range, and it is a generalization of the uniform, triangular, and power-function probability distributions. This paper gives the exact distribution of the product of two independent two-sided power-distributed random variables in a computable representation. The percentiles of the product are then computed, and a real data application is given.

Behavioral regulations and dispositional flow in exercise among American college students relative to stages of change and gender

Objective: The purpose of this study was to examine behavioral regulations and dispositional flow in exercise among university students in terms of gender and stage of change. Participants: Data were collected from American college students (N = 257; M_age ± SD = 23.02 ± 4.05) in Spring 2013. Methods: Behavioral regulations and dispositional flow in exercise were assessed, along with stage of change. Results: Exercisers in the maintenance stage of change displayed significantly more self-determined motivation to exercise and a greater tendency to experience flow than those in preparation and action stages. Significant correlations were observed among behavioral regulations and flow state. Nonsignificant differences were observed for gender on behavioral regulations and dispositional flow in exercise. Conclusions: The results suggest that promotion of self-determined motivation and dispositional flow in exercisers may improve the quality of their experiences, as well as to foster their exercise behavior.     

Telling about something that you do not really know: blind people are talking about vision!

In Turkey, the laws which define disability have become increasingly harsh, and require disabled people to be assessed in order to determine ‘how disabled’ they are. For blind people, as for other disabled people, these assessments have real consequences. This article aims to discuss an appealing piece that arose during a project, which has bearing on how disabled people tend to answer these questions. The participants are legally blind adults. We, as sighted researchers, asked totally blind individuals to describe their vision. Interestingly, they all answered this question without hesitation. The paradoxical nature of this question was only realized during the analysis. We requested the participants to talk about something they do not really know. This might be a reflection of our over-visualized world and might be due to our subtle prejudices. This type of questioning not only has implications for research, but also for assessments of disability in Turkey.

论《太一生水》的宇宙生成论是对老子道、物二元论的解释

老子的宇宙生成论是道物二元论,<太一生水>是对老子宇宙生成论的阐释与发挥.太一与老子的道是同一个概念,道就是规律.由于老子"物形之"之"物"没有明言,庄子把"物"理解为气,而<太一生水>把物分别解释为水、气、阴阳二气.水作为万物本原的思想,以及天地未生以前只有水这一传统观念,及老子哲学重水的特点,导致了<太一生水>作者对"物"的选择.这种选择也影响了后来的道家学派时老子的解读.
