Forensic Application of Analytical Mechanics in Fatal Fall From a Height

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.     

What do forensic analysts consider relevant to their decision making?

In response to research demonstrating that irrelevant contextual information can bias forensic science analyses, authorities have increasingly urged laboratories to limit analysts' access to irrelevant and potentially biasing information (Dror and Cole (2010) [3]; National Academy of Sciences (2009) [18]; President's Council of Advisors on Science and Technology (2016) [22]; UK Forensic Science Regulator (2015) [26]). However, a great challenge in implementing this reform is determining which information is task-relevant and which is task-irrelevant. In the current study, we surveyed 183 forensic analysts to examine what they consider relevant versus irrelevant in their forensic analyses. Results revealed that analysts generally do not regard information regarding the suspect or victim as essential to their analytic tasks. However, there was significant variability among analysts within and between disciplines. Findings suggest that forensic science disciplines need to agree on what they regard as task-relevant before context management procedures can be properly implemented. The lack of consensus about what is relevant information not only leaves room for biasing information, but also reveals foundational gaps in what analysts consider crucial in forensic decision making.

刑法学课程内容设置探讨——高校不同层次、不同专业刑法学课程教学内容的安排

刑法学体系结构庞大,刑法学课程可根据该体系的重点难点以及培养目标、实际需要等因素确定教学内容的安排。在专科、本科兼招的高等学校,既有必要安排好大专层次各专业的刑法学课程,又应该考虑好本科层次各专业刑法学课程的设置。

论“三队一室”警务模式存在的问题及完善

“三队一室”警务模式是集防范、管理、控制、打击乃至于服务于一体的运作模式,它符合社区警务要求的运作模式,能够大大促进警务效率。作为一种新模式,“三队一室”还存在推广应用、内部规范、外部协调等问题。为此,公安部应对“三队一室”作出明确的统一规定,目前,应在各地的城区派出所和有条件的乡镇派出所先实行,然后逐步推广“三队一室”模式。另外,对“三队一室”的权责应当明确,避免内部职能的冲突和外部权责的混乱。

INTRODUCING PERSPECTIVES IN FAMILY LAW AND SOCIAL SCIENCE RESEARCH

This article provides an editorial introduction to the following three related articles on the growing use and influence of social science research in family law. It first considers why this has become problematic and identifies some common strategies used by advocates, sometimes under the guise of scholarship, to destroy the standing of research findings contrary to their ideological or political position. Then it discusses briefly the remedies proposed to mitigate these kinds of problems within the following three articles.     

统一公法学与刑法及刑法学的关系

刑法与刑法学,刑法学与公法学、统一公法学之间不是一种简单的线性关系。从数学中的集合概念来看,狭义的刑法学是统一公法学的组成部分,它们之间是被包含与包含的关系,即狭义刑法学被统一公法学所包含,狭义刑法学是统一公法学的子集。但若以广义刑法学立论,则广义刑法学与统一公法学之间是一种交叉关系,重合的部分即是狭义刑法学,此乃统一公法学与广义刑法学两个集合的交集。
