Impact of Firearm Availability and Gun Regulation on State Suicide Rates

Past studies on suicide have investigated the association of firearm ownership and suicide risk in the United States. The aim of the present study was to build on previous work by examining the impact of firearm storage practices and the strictness of firearm regulation on suicide rates at the state level. Data were compiled from primarily three sources. Suicide and firearm ownership information was obtained from the Centers for Disease Control and Prevention. Strictness of handgun regulation was derived from figures available at the Law Center to Prevent Violence, and controls were taken from the US Bureau of the Census. Mixed models were fitted to the data. Household firearm ownership was strongly associated with both suicide by all mechanisms, and firearm suicide. Storage practices had especially elevated consequences on suicide rates. Percent with loaded guns and gun readiness increased suicide rates, and strictness of gun regulation reduced suicide rates. Ready access to firearms can make a difference between life and death. Loaded and unlocked firearms within reach become risk factors for fatal outcomes from suicidal behavior. Future research might want to examine ways of obtaining more recent data on individual firearm ownership. This study proposes several policy recommendations for suicide prevention.     

中国颜色体系研究

概述了用颜色立体模型表示物体颜色,并做定量表示的颜色体系研究的理论意义及应用价值。介绍了国际上影响较大的颜色体系理论和编制原则的特点。中国颜色体系研究是在对国际上其它颜色体系的理论分析和对颜色样品测试的基础上,确立其理论依据和编制原则,开展了中国人眼对明度、色调、彩度等间距排列的视觉评价实验,建立了中国颜色体系理论模型。同时研制出《中国颜色体系样册》。该项研究于１９９３年７月通过了国家自然科学基金委员会和中国科学院联合召开的成果鉴定会,并得到良好的评价,又于１９９４年６月通过国家标准审查。该项研究的完成和推广,不仅能为我国国民经济各部门的颜色控制、标定和交流提供科学的颜色定量手段,同时也是对实用色度学的发展和颜色标准化工作做了有益的工作,产生了积极的经济效益和社会效益。     

具身视角下的社会认知

摘 要：由于第一代认知科学存在着身心剥离的缺憾,具身化作为第二代认知科学的主要特征得到研究者的广泛关注,并且得到了来自神经科学领域的支持。随着研究的深入,具身学派提出,社会认知是否也应是具身的。现有研究发现具身性对个体评价、反应速度、言语理解、人际交往等方面都有不小的作用。但上述以身体模拟为主的证据仍不足以证明社会认知是具身的,具身学派还需解决诸如明确具身的定义、实验论证、明显区别于传统认知观等问题。     

工程哲学的兴起及当前发展

在哲学大家族中,工程哲学是一个新诞生的哲学分支. 在20世纪末的哲学地图上,"科学哲学"位于中心区,"技术哲学"位于边缘区,[1]而"工程哲学"则仅勉强地在"技术哲学"的边缘占据了一个不显眼的位置,也就是说,"工程哲学"在哲学地图上位于"边缘的边缘".

全身性感染与Toll样受体2、4相关性研究进展

全身性感染是由感染所致的临床综合征,Toll样受体(TLR)导致的体内信号传导,使炎症反应级联放大,以及诱发机体免疫功能紊乱,致使机体对病原体清除效率降低.因此,阻断TLR传导通路可能会抑制全身性感染发生和发展的进程.
