建构主义视域中的风险及其动态治理——以面粉增白剂的存废为例

风险是未来损失的可能性,具有社会建构的特征,"面粉增白剂"之争验证了建构主义风险理论。在建构主义视域中,风险治理不仅要使风险最小化,还要实现其他的政治和道德目标,并对影响风险的诸多因素进行反思。风险的动态治理,是实现制度动态效率的必然选择。它的有效性以结果为导向,合理性以未来为导向,进而需要不断学习,吸收新思想新观念,并逐步形成一种新的治理文化。     

简论晚明“西洋哲学”之输入

《记法》专门探讨"记忆"问题,是一部介绍西洋"认识论"或"知识论"的专著。《童幼教育》是教育学及伦理学专著,属哲学之一支,既是介绍"西洋法学"、"西洋医学"入中国之最早文献之一,亦是引介"西洋神学"及"西洋大学"之最早文献之一,可说"太西总学之大略"已赖此书输入中国。《西学凡》介绍了哲学学科四年之课程(第一年逻辑学,第二年物理学,第三年形而上学,第四年数学与伦理学),已经把当时"西洋哲学"之全部内容包含完了。《灵言蠡勺》分四篇,一论灵魂之体,二论灵魂之能,三论灵魂之尊,四论灵魂所向美好之情,是晚明一部专门介绍西洋"灵魂"学说之哲学典籍。这些书在中国之刻印,正值"西洋近代哲学"之发源期,它们没有把"西洋近代哲学"介绍到中国来,但却把"西洋近代哲学"之前的"西洋哲学"介绍到中国来了。近代以前"西洋哲学"之完整框架,已经在弗.培根活动的那时节,出现在晚明中国学术界。

Assessing Kaliningrad's Geostrategic Role: The Russian Periphery and A Baltic Concern

Recent developments in post-communist Europe and Latvia in particular have raised questions about political stability in new democracies there. This article argues for taking a long-term perspective on this problem in place of short-term judgments. In doing so, it makes special reference to the EU's political conditionality and its impacts on Latvia and then applies comparative lessons on democratic consolidation based on the concept of ‘partial regimes’. It becomes clear in this analysis that the consolidation process in Latvia has advanced over the past decade and more and, in this respect, the EU did have an important, though limited and rather specific, impact. Yet this process is still incomplete, with historical legacies being a major factor. The ethnic divide has also remained largely unresolved, party development problems have persisted and the public is still unconvinced by the actual democracy they see before them and is alienated by political elite behavior in particular. Hence, Latvia does not have a defective democracy as such, but further change is necessary before democratic consolidation may be achieved there.     

Gang Membership,Drug Selling,and Violence in Neighborhood Context

A prominent perspective in the gang literature suggests that gang member involvement in drug selling does not necessarily increase violent behavior. In addition it is unclear from previous research whether neighborhood disadvantage strengthens that relationship. We address these issues by testing hypotheses regarding the confluence of neighborhood disadvantage, gang membership, drug selling, and violent behavior. A three‐level hierarchical model is estimated from the first five waves of the 1997 National Longitudinal Survey of Youth, matched with block‐group characteristics from the 2000 U.S. Census. Results indicate that (1) gang members who sell drugs are significantly more violent than gang members that don’t sell drugs and drug sellers that don’t belong to gangs; (2) drug sellers that don’t belong to gangs and gang members who don’t sell drugs engage in comparable levels of violence; and (3) an increase in neighborhood disadvantaged intensifies the effect of gang membership on violence, especially among gang members that sell drugs.

高校突发事件的特征及其应对策略

高校突发事件具有区别于其他突发事件的特征,如参与对象的特殊性、诱发因素的多样性、事件的迅速扩散性和后果的严重危害性等。当突发事件发生后,高校应当采取以人为本、预防为主、实事求是、统一领导、团结协作、快速平息危机、总结经验教训等应对策略,以切实维护学校和广大师生的利益。     

Comparison of feature selection and data fusion of Fourier transform infrared and Raman spectroscopy for identifying watercolor ink

The identification of different kinds of watercolor inks is an important work in the field of forensic science. Four different kinds of watercolor ink Spectroscopy data fusion strategies (Fourier Transform Infrared spectroscopy and Raman spectroscopy) combined with a non-linear classification model (Extreme Learning Machine) were used to identify the brand of watercolor inks. The study chose Competitive Adaptive Reweighted Sampling (CARS), Random Frog (RF), Variable Combination Population Analysis-Genetic Algorithm (VCPA-GA), and Variable Combination Population Analysis-Iteratively Retains Informative Variables (VCPA-IRIV) to extract characteristic variables for mid-level data fusion. The Cuckoo Search (CS) algorithm is used to optimize the extreme learning machine classification model. The results showed that the classification capacity of the mid-level fusion spectra model was more satisfactory than that of single Infrared spectroscopy or Raman spectroscopy. The CS-ELM models based on infrared spectroscopy used to recognize the watercolor ink according to brands (ZHENCAI, DELI, CHENGUANG, and STAEDTLER) obtained an accuracy of 66.67% in the test set using all spectral datasets. The accuracy of CS-ELM models based on Raman spectroscopy was 67.39%. The characteristic wavelength selection algorithms effectively improved the accuracy of the CS-ELM models. The classification accuracy of the mid-level spectroscopy fusion model combined with the VCPA-IRIV algorithm was 100%. The data fusion method increased effectively spectral information. The method could satisfactorily identify different brands of watercolor inks and support the preservation of artifacts, paintings, and forensic document examination.
