The self-help clearinghouse concept: An evaluation of one program and its implications for policy and practice

Many clearinghouses have been organized within the last decade to promote mutual aid and to provide referral information about self-help groups to potential members. Few of the assumptions that underpin the operation of these programs have been evaluated, however. This paper presents an evaluation of the Self-Help Information Service, a clearinghouse integrated with a generic information and referral service. The results were generally positive with respect to operator and consumer satisfaction, community responsiveness, and the system's capacity to undertake numerous service and research functions. They also pointed up several changes that might be made to improve the system's impact. It is concluded that a new practice specialty might be developed within a clearinghouse context, and that the clearinghouse concept might serve as one cornerstone of a funding policy that supports the self-help approach.     

血管壁切应力的优与非优

在生理水平的血管壁切应力属于优性因子,能促进血管重建,抑制内皮细胞凋亡,调节内皮细胞分泌功能,使内皮细胞形态产生适应性变化;而显著升高或降低的血管壁切应力则属于非优因子,导致高血压恶性循环发生、促进动脉粥样硬化及动脉血栓形成。实现切应力非优向优转化的重要途径是降低高血压和选择性阻断切应力对基因表达的调节     

The power of transformation

Conclusion The answer to the question, how is man empowered to change? can be given in this form: We are empowered to change when we experience trust and acceptance coming to us from another person or group. Change occurs when our power of being is affirmed by other centers of power. This affirmation of our power of being overcomes the anxiety of nonbeing implied in every change. It supplies us with the courage to accept our acceptance and to exist in spite of threats to our existence. The content of trust in our experiencing that has taken the place of the prior anxiety in our experiencing reduces the disturbances that distorted our perception of reality. This enables us to receive reality more accurately and to symbolize it more exactly. Change then is an internal metamorphosis that is the result of a courage educed in us by external forces. The transformation of our internal experiencing is the prior condition and ground for the transformation of our symbolizations.He is a Fellow of the American Association of Pastoral Counselors and a member of the Academy.
