对杜威“教育无目的论”的思考及启示

杜威的"教育无目的论"强调的是教育过程中的目的,教育目的就是存在于过程中。他的教育无目的论在字面意义上通常被人理解为教育是没有目的的。那么,他的"教育无目的论"是否真的是无目的的,还是他另有所指?它的合理性又在哪?他的这一理论又对我们现代的教育又有什么启示?通过对其《民主主义与教育》的阅读,可以对他的"教育无目的论"进行进一步的理解。     

美国警察执法信息系统及其应用

美国警察执法信息网站是统一在互联网平台上建设与维护的.美国警察信息应用是依据其国家体制,联邦、各州、地方各级警察独立执法,对本级政府负责,相互之间无隶属关系.美国警察的执法信息系统包括应用软件、硬件和移动数据通信三个主要组成部分,其中应用软件是警察执法信息系统的一个关键组成部分.地理信息系统和犯罪地图绘制正在迅速成为美国警察机构内的执法信息系统的重要应用程序.美国警察执法信息系统及其广泛的应用,给我国公安信息化的建设与发展带来一些启示.     

近年来国内网络群体性事件对策研究述评

近年来,学术界围绕网络群体性事件的治理方略开展了多视角、宽领域的研究,主要成果可以概括为转变思路、变革制度和多样举措等三个方面策略,但受研究基础、视域的影响,中国特色的网络群体性事件研究话语体系尚未形成。     

无意思联络数人侵权的责任。承担——基于对《侵权责任法》第11、12条的分析

虽然《侵权责任法》第11、12条对无意思联络数人侵权作了规定,但仍未明确其责任的承担问题。《侵权责任法》第11、12条对无意思联络数人侵权行为的划分是以因果关系为标准的,任何一种侵权行为都是同一损害后果的必要条件而非充分条件,单独有其中任何一方的侵权都不会导致损害结果的发生,当且仅当两者结合时损害结果才会产生,反过来,损害结果的发生必须是两个人以上侵权行为的共同结合。在无意思联络数人侵权中,不论每个行为人的行为是否足以造成全部损害,只要在损害结果与每一个侵权行为都不可分的情况下,就应认定为连带责任,在损害结果可分的情况下,应认定为按份责任。     

On Developing an Inter-Agency Trust Scale for Assessing Governance Networks in the Public Sector

ABSTRACT

This article presents the development and validation of a psychometric scale for assessing public sector inter-agency trust. The instrument is grounded in contemporary trust theory and methodologically adapted from a measure developed for private sector alliances. Tested using four discrete studies of governance networks, each addressing transboundary environmental issues such as climate change and fisheries, the scale exhibits reasonably valid psychometric properties while also enabling visualized analysis of networked trust distributions. Based on this work, we outline further research needs with a view to stimulating greater trust research in governance networks and facilitating more collaborative and innovative policy outcomes in the public sector.

鸭疫里氏杆菌外膜微孔蛋白基因的克隆和序列分析及PCR检测方法的建立

根据GenBank中的鸭疫里氏杆菌(RA)外膜磷酸盐选择性微孔蛋白(Porin)基因序列设计特异性引物,以血清1、2、6、10、11、13、14和17型RA菌株的基因组DNA为模板均扩增出大小为1 212bp的目的片段,序列比对显示该基因在8种血清型菌株间同源性均大于99.6%。针对保守性最高的357bp片段设计特异性引物,建立了PCR检测方法,对鸭致病性大肠杆菌、鼠伤寒沙门菌、鸭巴氏杆菌及鸭肝炎病毒均未扩增出目的条带,表明该方法具有较高的特异性;敏感性试验显示最小检出量为73.96pg的基因组。应用建立的PCR方法对分离自吉林、河北及北京的8个菌株进行扩增,均在357bp处扩增出清晰的目的条带,与细菌分离鉴定的符合率达100%。本研究为RA的鉴定提供了新方法,为RA外膜微孔蛋白的后续研究提供了理论依据。     

流动注射—化学方光法检测人体血清内枸橼酸芬太尼

目的建立灵敏测定生物样品中皮克级枸橼酸芬太尼的方法。方法使用流动注射-化学发光法、鲁米诺-溶解氧体系检测芬太尼,蠕动泵流速2.0mL/min,鲁米诺与NaOH混合后被六通阀定量注入系统直至形成稳定基线,同时将样品推进送入混合管。碱性混合液被送入化学发光流通池产生化学发光,光电倍增管和光度计即检测到发光信号强度。结果在1.0～700pg/mL线性范围内,化学发光强度与芬太尼浓度呈线性关系,且发光强度随浓度增大呈增敏趋势,检出限低至0.3pg/mL。相对标准偏差在3.0%以内。分析过程可在30s内完成,采样频率120次/h。回收率98.9%～103.1%。结论该方法已经成功应用于检测人体血清中的枸橼酸芬太尼。     

Development of a Mobile Toolmark Characterization/Comparison System

Since the development of the striagraph, various attempts have been made to enhance forensic investigation through the use of measuring and imaging equipment. This study describes the development of a prototype system employing an easy‐to‐use software interface designed to provide forensic examiners with the ability to measure topography of a toolmarked surface and then conduct various comparisons using a statistical algorithm. Acquisition of the data is carried out using a portable 3D optical profilometer, and comparison of the resulting data files is made using software named “MANTIS” (Mark and Tool Inspection Suite). The system has been tested on laboratory‐produced markings that include fully striated marks (e.g., screwdriver markings), quasistriated markings produced by shear‐cut pliers, impression marks left by chisels, rifling marks on bullets, and cut marks produced by knives. Using the system, an examiner has the potential to (i) visually compare two toolmarked surfaces in a manner similar to a comparison microscope and (ii) use the quantitative information embedded within the acquired data to obtain an objective statistical comparison of the data files. This study shows that, based on the results from laboratory samples, the system has great potential for aiding examiners in conducting comparisons of toolmarks.
