四言诗的发展历程和衰落原因

本文通过对四言诗发展脉络的梳理，探讨了四言诗由盛到衰的三方面原因：相对于五、七言诗，它的音节节奏和拍节节奏单一，典重板滞而变化不足；创作过程中，“伤渊雅之致”，失去了四言诗的本色；古代诗体演变和进化的规律的结果。     

Intrinsic Versus Extrinsic Motivation: An Approach/Avoidance Reformulation

The main purpose of this article is to advance an alternative perspective on the relationship between intrinsic and extrinsic motivation, and in particular to examine critically the assertion that these processes are antagonistic such that the will to learn for its own sake is inhibited by the presence of extrinsic, tangible rewards and incentives such as school grades. The presumption of an antagonistic relationship largely depends on the theoretical perspective adopted. An alternative interpretation based on need achievement theory leads to distinctly different conclusions. Exploring this new perspective allows one to identify both the conditions under which intrinsic motives may coexist with extrinsic motives as well as to consider some of the means by which intrinsic motives and caring about learning can be stimulated in their own right in school settings.

在空灵的意境中滋养的诗性--探析曹晓宏教授的著作《砚池诗笺》

诗以有意境而自成高格，能写真景物、真感情者谓之有境界；诗是心灵之声，有意境则自有诗美诗，高度凝练才有韵律之美，诗品源于人品；诗道唯在妙悟。     

论自由概念(下)

自由与实行自我意志的障碍之消除,并不完全相同:自由仅仅是实行自我意志的自身之外的外在障碍之消除;实行自我意志的自身内在障碍之消除,并不是自由,而是利用自由的能力或条件。柏林与格林都误将利用自由的能力当作积极自由,而将自由本身当作消极自由。只不过,格林是直接将利用自由的能力叫作积极自由;而伯林虽然反对将利用自由的能力与自由本身等同起来,但是,由于他误将理智支配感情当作自由,因而也就间接地将利用自由的能力———亦即实行自己意志的自身内在的感情障碍之消除———叫作积极自由罢了。

论书法家的深刻孤独

深刻孤独是中国古代书法史上一个亘古常新的母题 ,无论是削发为僧、遁于山林的隐士 ;还是长歌当哭、戏笑人生的狂怪者 ;或是在人生舞台自由自在、安逸逍遥的社会宠儿 ;抑或是煞费苦心、日理万机为救国家人民出水深火热的人民公仆 ,他们都有一颗孤独的心。深刻孤独是书法大师生成的必备条件 ,正是因为深刻孤独的匮乏才使当代中国书法走向了衰落和危机     

Transforming engagement: a case study of building intrinsic motivation in a child with autism

This longitudinal case study of a 10‐year‐old girl with autism and severe communication impairment measures the impact of the MORE (Means, Opportunities, Reasons and Expectations) approach to enhancing engagement and communication. Through detailed observation of video data over a period of 28 months, engagement behaviours including interaction with adults and following adult directions increased, while resistant behaviours such as kicking, hitting and pushing adults away decreased. Fluctuation between different ‘states’ demonstrated that the frequency and duration of engagement was influenced by the MORE approach and an emphasis on developing intrinsic motivation. In order to enable further efficacy research, core features of the intervention and the changes in engagement over time are described.
