Validation studies of the ParaDNA® Intelligence System with artificial evidence items

Short tandem repeat (STR) profiling is one of the mostly used systems for forensic applications. In certain circumstances, STR profiling is time-consuming and costly, which potentially leads to delays in criminal investigations. LGC (Laboratory of the Government Chemist, UK) Forensics has developed a robust STR profiling platform called the ParaDNA^® Intelligence Test System which can provide early tactical intelligence and aid investigators in making informed decisions on sample prioritization for detection. Here, we validated the ParaDNA intelligence test for its application in forensic cases using a range of mock evidence items following guidelines set by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Specifically, we tested the sensitivity and accuracy of the ParaDNA intelligence test, as well as the success rates for detecting mock samples and for use in case scenarios. Our findings demonstrate that the ParaDNA intelligence test generates useful DNA profiles, especially for samples such as blood, saliva, and semen that contain ample DNA, indicating the benefits of including ParaDNA as a prior step in forensic STR profiling pipelines.     

新生代农民工精神文化需求问题探析

新生代农民工作为一个新兴的群体,是实现构建和谐社会伟大战略的重要推动者。随着社会的不断发展,新生代农民工对精神文化的需求将呈现一个不断上升的趋势,但是,在多元文化、经济收入、社会制度、自身条件等因素的影响下,新生代农民工在思想文化、娱乐文化、科技服务、社会交往等方面的精神文化需求却难以得到满足。解决这些问题需要政府、社会、企业以及新生代农民工主体等多方面共同努力。

Integration of the Family Therapy Specialist into Public School Pupil Personnel Services

SUMMARY

The integration of a full-time family counseling specialist into the Pupil Personnel Service (PPS) Team of the modern public school is described. The roles of the present specialists are delineated as well as the problems inherent within the present Pupil Personnel Services Team. Inclusion of a family counseling specialist on the PPS Team would help schools avoid the antagonist position they find themselves in when a family opposes their suggestions and interventions. In such cases, the PPS Team attempts to wrest control of the case from the parents which subjugates the family, limiting the family's inherent resilience and strength. The family comes to resent the PPS Team, seeing them as blameful and controlling. Conversely, the PPS Team comes to resent the family, claiming it is “dysfunctional” in some way and using diagnostic labels to satisfy themselves that their “expert” actions are justified. This antagonist position in the schools arises more out of fear of litigation than good case management. We propose a new integration of family system and school system. Creation of a family counseling specialist who is highly trained in systems, narrative and structural/strategic family therapy could ameliorate this antagonist problem. Numerous functions for such a new specialty are listed as well as suggestions for including this member into PPS Team work.     

3D Finite Element Model of Human Knee Injuries in the Traffic Accident

Objective To explore the injury mechanism of the human knee in a traffic accident by estab lishing a 3D finite element （FE） model. Methods The FE model, composed of femur, tibia, fibula, patel la, meniscus, knee ligaments and surrounding soft tissues, was reconstructed by CT scanning data from a male volunteer. Validation was performed by the lateral impact simulation, and the stress and strain re sults were obtained to be compared with those previously reported for injury prediction. Results The re suits derived from the FE model were found to be similar with those previously reported, most of the ligaments and meniscus wounded at 40 m/s collision, which was readily observed. Conclusion The simu lation results generated by FE model can be effectively used for the injury mechanism analysis of initial contact.

中国经济发展态势和调整转型——2013年第1季度宏观经济分析

今年1季度中国GDP增长7.7%,工业增加值增长9.5%,CPI上涨2.4%,与希望回升的预期相反,均比上年同期和上季度要低,但增长回落正是经济调整转型之机。M2余额超过百万亿元,不能仅从货币政策操作考察是否存在货币超发,而要深入一步,看看政府投资创造货币的特殊机制。房地产调控中的博弈,一方面说明政策设计存在缺陷;另一方面也与特殊的货币创造机制有关。撤销铁道部,组建铁路总公司,实现了组织机构上的政企分离,但经济上仍合在一起。以债务处理为契机,明晰产权安排和经营责任,进一步推进铁路改革。     

Age-Period-Cohort analysis: A design-based approach

This paper develops a design-based approach to identifying cohort effects in APC analyses. Cohort effects arise when one cohort is treated by a unique set of formative socialization experiences, which causes it to differ from other cohorts in relevant outcomes. APC analyses typically compare treated and untreated cohorts from a single population. Our approach introduces a second group—a control group, in which no unit is treated but that is otherwise similar to the first—and adapts difference-in-differences estimation to the APC framework. The approach yields two identification strategies, each based on transparent and testable assumptions. We illustrate how the method works and what is to be gained through three examples.     

关于行政传唤适用情况的调查分析——以河南省公安行政执法为例

通过对行政传唤适用情况的调研，发现行政传唤在适用中存在一些问题，主要是对行政传唤的适用期限理解错误、行政传唤适用对象混乱、强制传唤的适用随意性较大以及行政传唤缺乏救济途径，这既有立法的原因，也有执法理念的原因。为了防止出现上述问题，需要从立法上明确行政传唤的强制措施的属性，明确行政传唤的适用对象，明确传唤的启动条件和实施条件。
