Architecture for Provenance Systems

This document covers the logical and process architectures of provenance systems. The logical architecture identifies key roles and their interactions, whereas the process architecture discusses distribution and security. A fundamental aspect of our presentation is its technology-independent nature, which makes it reusable: the principles that are exposed in this document may be applied to different technologies

Users' trust in information resources in the Web environment: a status report

This study has three aims; to provide an overview of the ways in which trust is either assessed or asserted in relation to the use and provision of resources in the Web environment for research and learning; to assess what solutions might be worth further investigation and whether establishing ways to assert trust in academic information resources could assist the development of information literacy; to help increase understanding of how perceptions of trust influence the behaviour of information users

Requirements for Provenance on the Web

From where did this tweet originate? Was this quote from the New York Times modified? Daily, we rely on data from the Web but often it is difficult or impossible to determine where it came from or how it was produced. This lack of provenance is particularly evident when people and systems deal with Web information or with any environment where information comes from sources of varying quality. Provenance is not captured pervasively in information systems. There are major technical, social, and economic impediments that stand in the way of using provenance effectively. This paper synthesizes requirements for provenance on the Web for a number of dimensions focusing on three key aspects of provenance: the content of provenance, the management of provenance records, and the uses of provenance information. To illustrate these requirements, we use three synthesized scenarios that encompass provenance problems faced by Web users toda

Consumers' perception of food traceability in Europe

Food traceability has become mandatory since 1st January 2005 in the European Union. Traceability of products and activities in the supply chain has become a new factor of competitiveness in agribusiness and is deemed to be an important criterion of perception of food product quality and safety for consumers. This paper has three objectives: i) to get a deeper understanding of the role of the "ability-to- trace" in consumer decision- making process with respect to food, ii) to measure consumers' acceptability for food traceability, iii) to check the differences of these matters across twelve European countries in order to highlight any specificity. The purpose is based on the analysis of the verbatim recorded within twenty four focus groups discussions carried- out in autumn 2005.Food Traceability, Consumer Attitudes, Focus Groups, European Countries, Food Consumption/Nutrition/Food Safety,

Range and Limit of Geographical Indication Scheme: The Case of Basmati Rice from Punjab, Pakistan

Basmati is well renowned as the most aromatic rice over the world. Populated urban markets are prone to accept a premium to Basmati, whom price is the highest for rice on trade and domestic markets. Punjab province represents 90% of overall Basmati rice production in Pakistan since immemorial times. This area forms the genuine alluvial lands appropriate for Basmati cultivation. Due to its price premium, some opportunist behaviors appear such as cropping blending of polished long grain from other varieties. The need of protection is clearly documented, but the registration of a Geographical Indication, will probably increase Basmati market shortages.Basmati rice, Marketing, Commodity chain, Geographical Indication, Pakistan, Marketing, Q10, Q13, Q15,

Guidelines for the use of cell lines in biomedical research

Cell-line misidentification and contamination with microorganisms, such as mycoplasma, together with instability, both genetic and phenotypic, are among the problems that continue to affect cell culture. Many of these problems are avoidable with the necessary foresight, and these Guidelines have been prepared to provide those new to the field and others engaged in teaching and instruction with the information necessary to increase their awareness of the problems and to enable them to deal with them effectively. The Guidelines cover areas such as development, acquisition, authentication, cryopreservation, transfer of cell lines between laboratories, microbial contamination, characterisation, instability and misidentification. Advice is also given on complying with current legal and ethical requirements when deriving cell lines from human and animal tissues, the selection and maintenance of equipment and how to deal with problems that may arise
