ZnS和ZnS:Cu无机紫外荧光材料的制备及其在汗潜手印显现中的应用

目的制备荧光强度高、客体适用性广、显现效果优良且合成方法简单的ZnS及ZnS:Cu无机紫外荧光材料,并将其用于汗潜手印的显现。方法通过一步溶液反应共沉淀法制备ZnS无机紫外荧光材料,并在ZnS材料中加入Cu^2+得到ZnS:Cu以改善荧光性质,将其应用于普通客体(白色捺印纸、载玻片、铁架台、乳白色花纹瓷砖表面、磨砂化学实验台面、不锈钢表面)和复杂客体(拼色花纹瓷砖、农夫山泉塑料标签和杂志封面铜版纸)上汗潜手印的显现,并与传统荧光粉末显现效果进行对比。结果ZnS材料具有荧光性,并且在ZnS材料中掺杂Cu^2+后得到的ZnS:Cu材料荧光强度增强,荧光光谱范围变广,稳定性提升。显现汗潜手印时,适用客体范围更广,并且可通过调节激发光的波长呈现不同的显现效果。结论通过在无机荧光材料ZnS中掺杂Cu^2+可改善材料的荧光范围,从而得到适用于不同客体上汗潜手印显现且效果更好的ZnS:Cu无机紫外荧光材料。     

Race,Partisanship, and Political Trust Following <Emphasis Type="Italic">Bush versus Gore</Emphasis> (2000)

In contrast to what we know about the sources of political trust among whites, recent research suggests that political mistrust among blacks indicates discontent with the political system. The current study adds to research investigating racial differences in political trust by examining racial differences in the influence of the 2000 United States presidential election on political trust. Specifically, I test for whether whites and blacks adjusted their trust in government in response to the Supreme Court’s decision in Bush versus Gore (2000) and whether the influence of the Court’s decision on trust was dependent on partisan identification. The findings indicate that blacks perceived the Court’s decision as illegitimate, reinforcing their mistrust in their political system.

Eyewitness Lineups: Is the Appearance-Change Instruction a Good Idea?

The Department of Justice's Guide for lineups recommends warning eyewitnesses that the culprit's appearance might have changed since the time of the crime. This appearance-change instruction (ACI) has never been empirically tested. A video crime with four culprits was viewed by 289 participants who then attempted to identify the culprits from four 6-person arrays that either included or did not include the culprit. Participants either received the ACI or not and all were warned that the culprit might or might not be in the arrays. The culprits varied in how much their appearance changed from the video to their lineup arrays, but the ACI did not improve identification decisions for any of the lineups. Collapsed over the four culprits, the ACI increased false alarms and filler identifications but did not increase culprit identifications. The ACI reduced confidence and increased response latency. Two processes that could account for these results are discussed, namely a decision criterion shift and a general increase in ecphoric similarity.     

Incremental Validity of the Psychological Inventory of Criminal Thinking Styles and Psychopathy Checklist: Screening Version in Predicting Disciplinary Outcome

A group of 136 male inmates housed in a medium security federal correctional institution were followed for a period of 24 months for evidence of disciplinary infractions (incident reports) after completing the Psychological Inventory of Criminal Thinking Styles (PICTS) and being scored on the Psychopathy Checklist: Screening Version (PCL:SV). Age, prior incident reports, the PICTS General Criminal Thinking (GCT) score, and the PCL:SV total score were included in a series of negative binomial regressions and Receiver Operating Characteristic (ROC) analyses of three increasingly more serious outcomes: total incident reports, major incident reports, and aggressive incident reports. Results indicated that the PICTS GCT score and PCL:SV total score were incrementally valid predictors of all three outcomes, with the strongest effects occurring when more severe incident reports were predicted. On the other hand, only the PICTS GCT score and Proactive Criminal Thinking (P) scale produced more than one significant ROC finding.     

通往宪政国家的路径选择——从欧洲的哲学构建到北美的理性实践

在经历中世纪宗教束缚,以及文艺复兴、宗教改革的观念冲击后,17—18世纪欧洲思想家从哲学上建构了现代国家理论,摆脱了自然理性和宗教理性对国家观念的支配,开启了人类理性占主导地位的现代国家理论的建构。英国经“光荣革命”从传统封建王朝变革为现代立宪国家后,北美大陆通过独立战争向世界宣称“美利坚合众国”正式成立。一群既具长远政治眼光、又有强烈现实主义倾向的政治家,探索出一条建构现代宪政国家的政治道路。     

Re-examining the evidence on the electoral impact of terrorist attacks: The Spanish election of 2004

This paper re-examines the electoral effect of the 11-M terrorist attacks in Madrid. Previous research has focused on post-electoral surveys to construct counterfactuals for the evaluation of the electoral impact of the attack. Bali (Electoral Studies, 2007) claims that the terrorists attacks had an important electoral impact while Lago and Montero (2005) claim the opposite. In this paper I propose to re-examine the evidence using a methodological approach based on actual votes instead of opinions revealed by surveys, and the difference-in-differences estimator. The calculations under the counterfactual of “no terrorist attack” support the forecasts of the polls taken prior to the terrorist attack and the results of Bali (2007). The incumbent (conservative) party would have won the election with between 42% and the 45% of the votes, while the socialist party would have obtained 37% of the votes.

预备贩毒案件中的诱惑侦查行为

诱惑侦查的核心是国家作为诱惑者诱使被诱惑者实施犯罪，此种激励型侦查实践的核心在于，需要刺激犯罪的实际发生。与卧底侦查相比，诱惑侦查并不是一种对付有组织犯罪和职业型犯罪分子的专用武器，而是可以广泛利用于各种犯罪。
