Evaluation of Nile Red‐Loaded Mesoporous Silica Nanoparticles for Developing Water‐Soaked Fingerprints on Thermal Paper

Nile red has been an alternative reagent for detecting latent fingerprints on wetted substrates. However, the presence of methanol in nile red solution could make injury to handlers and destroy the traces on surfaces, such as texts on thermal papers. A novel small particle reagent formulation constituting of mesoporous silica nanoparticles (MSNs) based on nile red was prepared to overcome the problem. Compared with the conventional reagents Oil Red O or nile red solution, the nile red‐loaded MSNs are highly selective to lipid residues of fingerprints and showed a greater ability to develop clear, sharp, and detailed fingerprints on thermal papers after these were immersed in water. In addition, it can retain texts on the thermal papers well and use only water as a solvent. These suggested that nile red‐loaded MSNs are a safe, efficient, and convenient method to develop latent fingerprints on wide range of substrates of forensic importance.     

辽宁文化产业未来创新发展的路径选择

2018年9月,习近平总书记在深入推进东北振兴座谈会上发表重要讲话,明确指出了辽宁振兴存在体制机制、经济结构、开放合作、思想观念“四个短板”,并反复强调,先有思想的大解放,才有改革的大突破、制度的大创新、力量的大凝聚。这充分说明,新时代辽宁要实现全面振兴、必须要解放思想。《辽宁省文化产业振兴规划纲要》已经对我省未来文化产业的发展做出详细规划,提出了辽宁省文化产业的定位,以及发展思路、发展目标和发展路径,充分体现了我省具有地域特色的文化产业发展新格局。     

Continuity and Changes in the Developmental Trajectories of Criminal Career: Examining the Roles of Timing of First Arrest and High School Graduation

Early onset of criminal career is one of the most robust predictors of persistence in offending. However, many antisocial children do not become chronic adult offenders. Using longitudinal data of young male offenders in the California Youth Authority, we examined trajectories of criminal behavior from childhood to adulthood. We particularly focused on the main and interaction effects of age at their first arrest and completion of high school education. First, we found that, on average, cumulative crime trajectory was curvilinear, with a subtle increase in childhood followed by a rapid increase in late adolescence and a slow down in adulthood. Second, earlier starters had a steeper cumulative growth in criminal behavior over time. Third, finishing high school served as a potential turning point in offenders’ lives, particularly for later starters. The results highlight that continuity and desistance in crime can be partially understood by timing of significant events and heterogeneity in response to turning points. Misaki N.

人民公社制度的另类分析——新制度经济学的视角

人民公社曾经是社会主义的重要实践,它的解体,给我们留下了很多思考。很多人认为这是公社的土地公有制对农民的激励不足造成的。从劳动力产权这一新的角度来看,人民公社的解体是由于公社对劳动力产权的安排导致了劳动力产权残缺,这直接危害了农民的直接利益,对农民激励不足,并最终导致了人民公社实践的失败。     

Accuracy of facial soft tissue thickness measurements in personal computer-based multiplanar reconstructed computed tomographic images

The purpose of this study was to determine the precision and accuracy of facial soft tissue measurement using personal computer (PC)-based multiplanar reconstructed (MPR) computed tomography (CT) images and to evaluate the effect of the various CT scanning protocols on the facial soft tissue thickness measurement. Thirteen different CT imaging protocols were used to image a cadaver head. MPR reformations and three-dimensional (3D) reconstructions viewed on a laptop PC were used to make measurements at six specific sites on each set of images. These measurements were compared to physical measurements at the same sites. Increasing the slice thickness resulted in decreased image quality. Within the same slice thickness, increasing the pitch ratio in the spiral mode, resulted in decreasing image quality. The image quality of conventional CT scanning was relatively poorer than that of the spiral CT scanning. However, the mean deviation from the physical measurement was within 0.43 mm in every instance. This mean deviation was quite small and clinically acceptable for measuring the soft tissue thickness of the facial area. PC-based MPR CT images of the face using routine scanning CT protocols can be used to accurately measure soft tissue thickness in the facial region. However, for more fine and accurate data collection, scanning protocols with slice thicknesses less than 5mm, and a spiral/helical mode pitch less than 2:1 are recommended.     

死刑限制论的一个切入--以故意杀人罪为线索的展开

在死刑限制论成为我国刑法理论现实选择的情况下,在立法上有必要取消部分罪名的死刑刑种配置,根据故意杀人罪的不同情况,配置其罪刑系列,同时将被害人过错的酌定从轻情节法定化;在司法上适用死刑应该"慎重谦抑";在解释论上有必要通过实质解释为削减死刑做出贡献.     

财产支配权论要

财产支配权是权利主体直接支配标的物以实现权利内容,并可排斥他人干涉的权利。物是财产支配权客体的一般范畴,包含有体物和无体物两种形态。我国民法典中可将“有体物支配权——无体物支配权”与“完全支配权——限制支配权”两种模式加以整合,建立与请求权相对应的财产支配权体系。     

对我国民事程序选择权的反思与建构

现代意义上的法治本质上是人类规制自我生活的一种方式和角度,它的成长离不开以人的价值及利益为核心的人文精神底蕴.因此,法治理念指导下的制度设计,应体现以人为本的价值取向.在民事诉讼中赋予当事人程序选择权,使当事人在法律规定的范围内能自主选择纠纷解决方式,以及在解决纠纷过程中选择相关事项,不仅有利于克服民事诉讼的局限性,实现民事诉讼程序所追求的各项价值,而且由于其体现了对当事人意志的尊重,更是包含着使法治得以成长的契机.

当代资本主义的新变化对社会主义发展的影响

20世纪 70年代以来 ,当代资本主义发展出现了一些令人注目的新变化 ,其中具有代表性和全局性的有经济全球化 ,新科技革命和第三条道路。这三大变化不仅对当代资本主义的历史命运而且对社会主义的发展前途都具有重大而深刻的影响。然而这些变化没有也不可能从根本上克服资本主义的基本矛盾和危机 ,更不会引起资本主义经济和政治制度的根本性变革 ,因而也不会改变资本主义必然灭亡 ,社会主义必然胜利的客观规律。
