Social action to help the poor should have the following characteristics:the poor should see themselves as the source of the action;the action should effect in major ways the preconceptions of institutions and persons who define the poor;the action should demand much in effect or skill;the action should be successful and the successful self-originated important action should increase the feeling of potential worth and individual power of individuals who are poor.

How is collective action brought about? This perennial question has been approached from different angles. Structuralists insist that structure is the source of collective action, that structure gives rise to ideology which in turn determines collective action. Utilitarians maintain that only the community with shared benefits can engender collective action, and rational individuals may throw collective action into predicament. Constructionists are of the opinion that people act on the basis of the meanings derived from social construction, and that social mobilization is needed for such collective action.

结构主义者认为结构才是集体行动的本源，结构决定了意识形态从而也决定了集体行动；功利主义认为有着共同利益的群体成员才有集体行动的可能，但个人理性会令集体行动陷入困境；而建构主义则认为人们是依据意义的社会建构来采取行动的，但集体行动所需的共同意识、资源、成员都需要组织者积极动员，除了群体的意义建构在影响集体行动，行动者的理性也仍然在考察不断变化的周围世界的基础上参与行动抉择。

The approximate structure of nonlinear action of climatic atmosphere and ocean is: the nonlinear action decreases usually with increasing latitude, which is related to the role of the Coriolis force in fluid motion; the nonlinear action changes with the anomalous cyclonic or anticyclonic circulation shear, for instance, when the strength of anomalous eastward zonal circulation is comparable to that of anomalous meridional circulation, the nonlinear action is the strongest; wind stress plus gradient forces enhance the nonlinear action, etc..

气候海洋与大气非线性作用的大致结构是：通常与科里奥利力对流体运动的规范作用有关，非线性作用随纬度增加而减弱。距平流场的切变结构及其沿经向与纬向上强度的比较直接改变气候大气和海洋的非线性作用(比如，向东的距平环流强度与经向环流强度相当时，非线性作用最强)，较强的外部驱动使非线性作用加大等等。
