Food cooperatives have played a vanguard role in consumer protection through (a) information and education, (b) selective merchandising and boycotts, and (c) political lobbying. While education and selective merchandising benefit primarily their own membership, the political efforts have benefited all consumers.  相似文献

Accident investigation is frequently cited as the cornerstone of an effective occupational health and safety program. We suggest that the literature on accident investigation is based on a model of witnesses as neutral and accurate recording devices. The literature on eyewitness testimony and criminal investigation offers strikingly different conclusions. We review these findings and point to their implication for research on accident investigation in occupational health and safety contexts.  相似文献

We demonstrate here the successful use of laser capture microdissection (LCM) and DNA fingerprinting in the identification of a case of gastric bioptic specimen mix-up. A 70-year-old man, suffering from chronic atrophic gastritis, underwent to a gastric biopsy and received a diagnosis of gastric cancer. In the absence of any clinical evidence of gastric cancer, a specimen mix-up was suspected. LCM was used to retrieve gastric cells from the histologic slide, classified as gastric carcinoma, and suspected to be mislabelled. DNA was extracted from microdissected cells, and a total of 16 different genetic loci were analyzed, using an identity test. Comparison of the results with those obtained using DNA extracted from a control slide, and from patient's saliva, demonstrated a distinct DNA fingerprint pattern in all genetic markers examined, clearly indicating the occurrence of a specimen mix-up. The combined use of LCM and DNA fingerprinting represents the most accurate and sophisticated method available for the identification of specimen mix-up, especially when only the tissue on the suspected slide is available.  相似文献

Allele frequencies for 16 short tandem repeats (STR) loci were determined with a sample of 230-300 unrelated individuals from the population of Rio de Janeiro, Brazil. The loci are the most commonly used in forensic and paternity testing, being analysed by the Identifiler (Applied Biosystems) and PowerPlex 2.1 (Promega) commercial kits. It was proved that Penta E and D18S51 are the most polymorphic loci.  相似文献

This article explores the role that ground troops play in aerial campaigns. Specifically, it intends to explain how ground troops affect the duration of aerial bombing campaigns. It distinguishes between the effect of ground troops on the duration of aerial campaigns that are selective and on those that are more general and less discriminate (using newly coded data on aerial strategies). The effect of ground troops may vary depending on how air power is being used. Ground troops may increase the duration of aerial campaigns in cases in which selective strategies are used during the aerial bombing campaign. In these cases, states lose the possibility of quick, “clean” victories once ground troops are introduced. In the cases of the less-discriminate bombing campaigns, the effect of ground troops is the opposite: They shorten the duration of the bombing campaign, possibly through the increased effectiveness of a combined arms approach.  相似文献

Although the prosecution of large-scale crimes at the internationallevel shares some similarities to the prosecution of organizedcrime at the national level, there are a number of importantdifferences that make the two areas hardly comparable. Two distinctivetraits of international criminal proceedings stand out in thisregard: (i) the lack of any enforcement agency that would allowprosecuting authorities to carry out investigations on the territoryof an interested state without its assistance and the absenceof a general power to carry out such arrests, which render statecooperation of prime importance and (ii) the fact that the proceduralmodel of international criminal tribunals is mixed containingelements of accusatorial (common law) as well as inquisitorial(civil law) systems. As far as prosecutions are concerned, usefulconcepts and procedures adopted from both legal traditions canbe found in the Statute, the Rules of Procedure and Evidenceas well as in the approach of prosecutors, defence counsel andjudges to the introduction of evidence and, more generally,to the manner in which proceedings are conducted. One of themain examples of this is the acceptance of proof of facts bymeans other than oral evidence as a result of the influenceof the civil law tradition, which has progressively made itsway in the procedural system of the International Criminal Tribunalfor the former Yugoslavia (ICTY). Yet, on the other hand, somemethods normally resorted to in national criminal prosecutionmay turn out to be useful at the international level, such asresorting to insider witnesses. Although known to domestic systems,such practice may have a particular significance in the contextof the prosecution of international crimes. So have additionalforms of criminal participation (such as the notion of jointcriminal enterprise). Only a mixing of traditional and innovativeinvestigative tools and the proper balance of the differentlegal cultures can ensure effective prosecution of internationalcrimes.  相似文献

Fifty shopping bags, commonly encountered in the packaging of drug doses, were characterized by thickness measurements, infrared spectroscopy and differential scanning calorimetry. By these very straightforward and inexpensive techniques, without sample preparation, nearly all the considered samples could be discriminated. Ninety-seven percent of the possible pairs of white, apparently similar dull polymer films were differentiated. The rather large degree of variability existing in grocery bags, even though they are mass produced, was shown, confirming that these items can be useful in tracing the source of illicit drug doses.  相似文献
