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

Demonstration of a gastric bioptic specimen mix-up by laser capture microdissection (LCM) and DNA fingerprinting 总被引:1,自引:0,他引:1

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

Abstract An issue now facing the federal government is whether and, if so, how to intervene to prevent mortgage prepayments and defaults on federally assisted low‐income rental units. This paper presents the preliminary estimates of the potential scope of the problem in terms of the possible incidence and timing of these actions, and the costs of preventing them. The estimates are based on modified versions of the model developed for the National Low Income Housing Preservation Commission's study, Preventing the Disappearance of Low Income Housing. An intermediate version of the modified model predicts 45 percent fewer defaults, 154,000 versus 280,000 units, and 45 percent lower total costs for preventing defaults, $4.6 billion versus $8.4 billion. On the other hand, 16 percent more prepayments are predicted, 283,000 versus 243,000 units. Estimated total costs for preventing prepayments are 17 percent lower, however — $8.5 billion versus $10.3 billion. 相似文献

Information sharing research has largely focused on capturing operational practices related to the exchange of information. A noticeable shortcoming of this developing literature is the lack of scholarly attention focused specifically on analytic personnel. The present study employs semi-structured interviews with 23 personnel that comprise the analytic unit within a regional fusion center located in a large metropolitan area in the United States. Findings indicate that there is significant ambiguity surrounding the organizational and geographic audiences to which intelligence products should be tailored. Moreover, it appears information sharing is sparse and reliant upon personal relationships between analysts and external organizations. Lastly, analysts do not receive feedback pertaining to the content and effectiveness of intelligence products created. These findings may be generalized to other analytical organizations whose primary goal is to gather, analyze and disseminate intelligence. Action steps for policymakers are provided. 相似文献

Abstract For many customers and consumers, the brand ‘is the product’. Managers and marketing specialists therefore consider branding as a key strategic tool used to create awareness, reputation and build the organisation's image. The brand image results from contacts that stem from both the marketing and communications domains. To develop a synergistic brand identity all levels of consumer interaction or contact with the brand must be addressed and not only those delivered through planned marketing communications efforts. The purpose of this article is to provide an overview of the theory underlying the perceived nature and role of alternative brand communication contacts, within the context of the outside-in integrated brand contact approach in the South African marketing and communications industry. Certain propositions will be formulated to serve as stimuli that can be used to critically assess the inclusion of alternative brand communications techniques as an extra function of Integrated Marketing Communications (IMC). Suggestions for future research will be offered. Vir baie verbruikers en kliënte is die handelsmerk die ‘produk’. Bestuurders en spesialiste in bemarking beskou die handelsmerk dus as 'n kern strategiese wapen wat aangewend word om bewuswording en reputasie te bou en die organisasie se beeld te vestig. Die handelsmerkbeeld het sy oorsprong in kontak wat uit beide die bemarkings- en kommunikasiedomeine voortvloei. Die ontwikkeling van die handelsmerkidentiteit op 'n sinergistiese wyse vereis dat alle vlakke van kontak en interaksie met die handelsmerk aangespreek word. Die doel van hierdie artikel is om 'n oorsig te gee van die teorie wat die aard en rol van alternatiewe handelsmerk kommunikasie-kontakte, in die konteks van die uitwaartse-in, geïntegreerde handelsmerk kommunikasie in die Suid Afrikaanse bemarkings- en kommunikasie-industrie, onderlê. 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
