我们每个人都会有自私自利的一面及和善大度的一面。当和善大度的一面闪现时,我们展示出来的是自己最好的一面。     

罗素、斯特劳森和唐纳兰的摹状词理论之比较

摹状词理论一直是西方语言哲学研究的热点问题之一,众多学者各抒己见。其中具有较大影响的有罗素、斯特劳森和唐纳兰。文章通过对三人摹状词理论的分析与比较,发现罗素主要是从语义角度谈论摹状词的指称,斯特劳森则是从语用学层面研究语词的,唐纳兰关于限定摹状词的两种用法的观点,实际上是对罗素和斯特劳森观点的发展,特别是对斯特劳森的工作的进一步深化的发展。     

Correspondence of Pubertal Neuroendocrine and Tanner Stage Changes in Boys and Associations With Substance Use

This study examined correspondence between timing (onset) and tempo (rate) of sexual maturation prospectively (average ages 11–16 years) measured by gonadal hormones and secondary sex characteristics (Tanner stage) using dual-process models, and associations of these measures with substance use (SU) involvement in boys at age 16 years (N = 534, 77.5% White/22.5% Non-White). All measures of timing were highly associated. Early Tanner stage timing often predicted slower increases in gonadal steroids, but not the reverse; patterns varied by ethnicity. Hormone and Tanner stage measures were similar earlier in development but diverged later in development. In White boys only, early timing of the pubertal rise in testosterone was associated with increased SU involvement, suggesting a physiological rather than psychosocial mechanism of association.
