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. 相似文献

ABSTRACTIncreasingly, a diverse set of policy communities, including those with defence, development and environmental mandates, frame climate change as a security threat. Most often this discursive formation labels climate change as a ‘threat multiplier’. This framing, however, is vague, linear and leaves many questions unanswered regarding how institutions can develop and implement policy that addresses the joint challenges of climate change, conflict and security. Utilising a mixed-methods approach, and grounding data collection in US policy communities, this article examines how policy actors and institutions integrate climate-security discourses into policy processes. The objective of this research is to provide direct insight into how the discourses and technical understandings of climate-security transition into policy priorities and implementation realities. This research identified three common approaches to climate-security: (1) A challenge of adaptation and resilience; (2) A potent political argument; and (3) An issue of limited importance and feasibility. These approaches, however, are inconsistent across sectors and within organisations, suggesting a lack of cohesion and considerable challenges in identifying and responding to climate change as a ‘threat multiplier’. 相似文献

Die von Deutschland nach Art. 59 Abs. 2 GG ratifizierten europ?ischen und internationalen übereinkommen zum Denkmal- und Kulturgüterschutz
müssen in nationales Recht transformiert werden. W?hrend die L?nder im Rahmen ihrer Kompetenz (Art. 30, 70, 83 GG) Denkmalschutzgesetze
erlassen haben, hat der Bund in einschl?gigen Gesetzen wie dem Bundeswaldgesetz den Denkmalschutz bisher nicht berücksichtigt.
Dabei ist bei einem Waldanteil von 30% der Wald mit seinen historischen Kulturlandschaften und seinem Waldboden als Archiv
der Natur- und Kulturgeschichte von besonderer Bedeutung. Da Deutschland 60 Jahre nach Kriegsende endlich auch ausdrücklich
ein Kulturstaat werden soll, ist es an der Zeit, dass die Belange des Denkmalschutzes auch im Bundeswaldgesetz (z.B. §§ 1,
2, 9 oder 11 BWaldG) berücksichtigt werden. Einige Verpflichtungen zum Denkmal- und Kulturgüterschutz sind heute ohnehin bereits
V?lkergewohnheitsrecht (Art. 25 GG). 相似文献

The EU has regulated chemicals since the late 1960s using both general and sectoral legislation, and exposure-based, hazard-based and risk-based decisions. A new proposal from the European Commission – on the Registration, Evaluation and Authorization of Chemicals (REACH) – will build on the experiences of the existing legislation and introduce some new concepts in the management of chemicals. This article is aimed at assessing the current chemical control mechanisms in the EU and those put forward in REACH to demonstrate how REACH is a new paradigm in chemicals management. REACH will carry forward today's experience and approach to the management of chemicals in the EU and introduces some novel aspects, such as utilizing market-based mechanisms and putting into operation the 'substitution principle'. 相似文献

In 1970, the Congress enacted the Organized Crime Control Act. Title IX of the 1970 Act is the Racketeer Influence and Corrupt
Organization Act or RICO. This Act had its origins in legislation going back as far as 1934, but coming forward to 1961. The
1970 Act borrowed ideas from this earlier legislation, principally “enterprise,” but also the use predicate statutes to define
“racketeering activity.” The ideas are not new, but their combination affects how prosecutors and law enforcement agents investigate,
try, and sanction violations of the Act. RICO’s drafting also reflects organizational theory and economic analysis. The investigation
and prosecution of a single crime committed by an individual on a single day and in a single place maybe done using one set
of procedural and evidentiary rules. Nevertheless, the investigation and prosecution of patterns of diverse offenses committed
by, through, and against licit and illicit enterprises require sophisticated procedures, evidentiary rules, and criminal sanctions.
In addition, antisocial conduct is more than a challenge to the administration of criminal justice; it also requires the full
panoply of civil sanctions, including public injunctions as well private enforcement of injunctive relief and treble damages.
RICO has had a profound effect on the prosecution of organized crime, white-collar crime, and other forms of similar criminal
behavior.
