保护生命健康事关人民幸福——就控烟公约专访中国疾控中心副主任、控烟办主任杨功焕

5年前的1月9日,《烟草控制框架公约》经全国人大常委会批准后,在我国正式生效。 作为由世界卫生组织主持达成的国际公共卫生条约,公约要求各缔约国通过参与打击烟草流行的斗争,保护本国人民健康。     

The Strategic Use of Gain- and Loss-Framed Messages to Promote Healthy Behavior: How Theory Can Inform Practice

Message framing provides a theoretically grounded approach to the development of effective health messages. In this study, we review the state of research and theory on message framing ( Rothman & Salovey, 1997 ), and how it can inform efforts to enhance health practices throughout the cancer care continuum. Gain-framed appeals are more effective when targeting behaviors that prevent the onset of disease, whereas loss-framed appeals are more effective when targeting behaviors that detect the presence of a disease. In light of these findings, we consider how message frames may affect other types of health behaviors and identify the need to understand better the processes that shape how people construe health behaviors.

十年变革清洗业旧貌换绿颜

工业清洗的应用范围甚广,涵盖了为数众多的制造业领域,从原始的金属加工到高科技的印刷线路板制造都不可或缺。近年来,迫于地方政府、国家乃至世界范围强烈要求减轻对环境的破坏这一呼声,清洗业发生了巨大的变化。同时,清洗业的发展也带来了一系列挑战,归根结底,这些挑战可以汇总为一句话:如何在不降低各个行业的清洗标准的情况下,将清洗操作所带来的负面影响降低到环境可以承受的程度。     

A Decade of Kasabov's Evolving Connectionist Systems: A Review

Evolving connectionist systems (ECoSs) are a family of constructive artificial neural network algorithms that were first proposed by Kasabov in 1998, where ldquoevolvingrdquo in this context means ldquochanging over time,rdquo rather than evolving through simulated evolution. A decade on the number of ECoS algorithms and the problems to which they have been applied have multiplied. This paper reviews the current state of the art in the field of ECoS networks via a substantial literature review. It reviews: (1) the motivations for ECoS; (2) the major ECoS algorithms in use; (3) previously existing constructive algorithms that are similar to ECoS; (4) empirical evaluations of ECoS networks over benchmark datasets; and (5) applications of ECoS to real-world problems. The paper ends with some suggestions of future directions of research into ECoS networks.
