Bjorn G. Hansen Mark Blainey 《Review of European Community & International Environmental Law》2006,15(3):270-280
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.

States Senate Committee on the Judiciary in 1969-70 when the Organized Crime Control Act of 1970, Pub. L. No. 91-542, 84 Stat.
922 (1970) was processed, Title IX of which is the Racketeer Influence and Corrupt Organization Act or RICO. For a general
treatment of the statute from a variety of perceptive, see the collection of law review literature in G. Robert Blakey & Kevin

Liability under RICO,” 33 Amer. Crim. L. Rev. 1345, 1348 n. 3(1996). 相似文献

The present study measured the existence of traumatic stress symptomatology as reported by certified law enforcement officers
within the State of Delaware. A questionnaire was devised which documented age, sex, race, education, years of service, marital
status, children, rank, position, and shift work. The questionnaire was divided into parts which assessed the exposure and
the frequency of specific traumatic incidents experienced in the line of duty, and the frequency of experienced traumatic
symptomatology criteria: re-experiencing, numbing, and arousal. 相似文献

This study aimed to expand the scope of previous research by assessing the effectiveness of soot-removal techniques on glass from petrol-bomb debris using methods of 1% and 2% sodium hydroxide (NaOH) solutions, ultrasonic bath and vacuum suction. Of particular interest were the 1% and 2% NaOH solutions applied to the soot-covered surfaces. Petrol bombs containing petrol or a 50:50 mix of petrol and motor oil were exploded and the debris was collected for analysis. Favourable results were found to varying degrees using each of the soot-removal methods with the 1% and 2% NaOH wash solutions, being the most useful. The 2% NaOH solution also proved successful as a soak to loosen and remove heavy contamination of soot and accelerants without damaging the finger mark beneath. This study also found that recovery of finger marks in blood from beneath soot using the 2% NaOH solution was possible. Finger marks were also applied to glass bottles with plastic adhesive labels, and providing the fire damage is not too great marks were also retrievable. Results from this study lead to the conclusion that the NaOH wash solution is ideally suited for soot removal to reveal latent and blood-contaminated marks both within the laboratory and at crime scenes. 相似文献
