Precautionary Principle, its Interpretation and Application by the Indian Judiciary: ‘When I use a word it means just what I choose it to mean-neither more nor less’ Humpty Dumpty

The precautionary principle is accepted in India as a fundamental tool to promote sustainable development and is employed within Indian environmental governance to promote better health and environmental decisions. Scientific uncertainty is at the core of the precautionary principle. The application of the precautionary principle is an open-ended issue. This article seeks to add to the limited empirical studies on the understanding, appreciation and application of the precautionary principle by key environmental actors, as differing legal responses and decisions may be irreversible before conclusive scientific knowledge and evidence become available. Building on researcher’s unique Indian data, and drawing on the theoretical insights developed by Charles Weiss, an explanatory environmental framework addresses the uncertainty of science by assembling a scale of legal standards arranged in a hierarchy of levels of increasing certainty familiar to lawyers and the judiciary. Reported Indian cases from the Supreme Court and the National Green Tribunal are selected to illustrate levels of scientific certainty or uncertainty and corresponding legal standards of proof constituting acceptable bases for legal decisions in practical context especially the precautionary principle. The article suggests India should develop a framework of guidelines that would provide an effective roadmap for decision-makers applying the precautionary principle

Information quality assessment in Korean manufacturing organization

Information quality is a complex problem. Issues relating to information quality are strongly embedded in the context of the operations of information systems. Information quality issues, therefore, have qualitative as well as quantitative underpinnings, which affect on the various dimensions of information quality. In order to improve information quality, it is essential to assess its various dimensions. This assessment provides the gaps that work as the building blocks for improving quality of information. However, assessing information quality dimensions is extremely intricate because each dimension depends upon other dimensions, which makes it difficult to objectively assess these dimensions. This research utilizes a product perspective of information and applies Six-Sigma methodology to assess information quality. It describes a case study of a Korean manufacturing organization where analytical hierarchy process and quality function deployment was utilized to determine the mutual relationships of information quality dimensions and critical to information quality factors.<br /

Quality management and contractual incompleteness: grape procurement for high-end wines in Argentina

International audienceSourcing grapes from independent growers for use in top quality wines sold on the international market is a major organisational challenge for corporate wineries. Our paper adds to the small existing literature addressing these coordination issues in the New World wine sector, by going deeper into the specifics of the contracts, as well as the "transaction cost economising" argument. Based on a case-study carried out in the Argentine province of Mendoza, this article presents an in-depth analysis of the technical process, in order to identify the contractual hazards posed by asset specificity, measurement costs, and non-contractible actions. Drawing on contract completion and dual sourcing literature, it analyses the contractual and non contractual mechanisms (price incentives, grower monitoring, allocation of decision rights to the winery, role of backward integration into production) used to govern such grape transactions. Through our analysis, we were able to arrive at four main conclusions. Firstly, most agreements are still verbal, with the exception of occasional written contracts, limited to a few legal provisions. It became clear to us that this approach to forging agreements is not always adequate in managing the inherently complex interactions between grape varieties, soil, farming practices and wine-making processes in high-end wine production. Secondly, extensive decision rights are allocated to wineries, to deal with incompleteness. These are key decisions to be taken during the cropping and harvesting process. Thirdly, pricing is generally kept flexible, with grape prices negotiated ex-post. This means that trade imbalances tend to be resolved in the long term. Winegrowers also benefit from financial rewards to compensate for allocations. Finally, any potential opportunistic behaviour by wineries with regards to asset specificity (in particular yield limitation) and allocation of rights is kept at bay by mechanisms such as winery reputations and credit third-party guaranty. This type of behaviour by growers is similarly deterred through monitoring and vineyard ownership on the part of the wineries

Theoretical models of the role of visualisation in learning formal reasoning

Although there is empirical evidence that visualisation tools can help students to learn formal subjects such as logic, and although particular strategies and conceptual difficulties have been identified, it has so far proved difficult to provide a general model of learning in this context that accounts for these findings in a systematic way. In this paper, four attempts at explaining the relative difficulty of formal concepts and the role of visualisation in this learning process are presented. These explanations draw on several existing theories, including Vygotsky's Zone of Proximal Development, Green's Cognitive Dimensions, the Popper-Campbell model of conjectural learning, and cognitive complexity. The paper concludes with a comparison of the utility and applicability of the different models. It is also accompanied by a reflexive commentary[0] (linked to this paper as a hypertext) that examines the ways in which theory has been used within these arguments, and which attempts to relate these uses to the wider context of learning technology research

Legislative Decision Making on Education Issues: A Qualitative Study

The purpose of this descriptive, single case study was to provide knowledge and insight about state education policy-making, specifically, the process by which education-related bills pass through a legislature. This study was also designed to identify factors of influence shaping legislative decision-making as perceived by lawmakers and observers of the legislative process. Sources of evidence included interviews, direct observation, archival records, public records documentation, and tape recordings of committee meetings and Senate floor sessions. Results show that a bill\u27s fate is subject to many planned and unplanned sequential steps, and to a collection of diverse personalities that drive the legislative process. Trust forms the foundation upon which other factors depend including bill sponsors, party leadership, lobbyists, fellow legislators, and constituents

Studying the NAIRU and its Implications

The current paper is a means of demonstrating our knowledge about macroeconomic theories, and its key variables, phenomena, and history. Given the key role that the Non-Accelerating Inflation Rate of Unemployment (NAIRU) has in the macroeconomic theory as well as its role in determining employment theories, it is raised the need for a thorough evaluation of its origins and a brief explanation of some of the claims surrounding it. In these grounds, this study aims at integrating and generalizing findings and presenting the changes within the macroeconomic field over the years by investigating theories, identifying methodological strengths and the weaknesses in the body of the macroeconomic research about the concept of NAIRU. In order to help the reader to avoid misunderstandings we define the best descriptors and identify the best sources to use in the review literature related to our topic, we rely on primary sources in reviewing the literature, we examine critically all aspects of the research design and analysis, and we consider contrary findings and alternative interpretations in synthesizing quantitative literature.NAIRU, macroeconomic policies

Rough Set Approach to Incomplete Multiscale Information System

Multiscale information system is a new knowledge representation system for expressing the knowledge with different levels of granulations. In this paper, by considering the unknown values, which can be seen everywhere in real world applications, the incomplete multiscale information system is firstly investigated. The descriptor technique is employed to construct rough sets at different scales for analyzing the hierarchically structured data. The problem of unravelling decision rules at different scales is also addressed. Finally, the reduct descriptors are formulated to simplify decision rules, which can be derived from different scales. Some numerical examples are employed to substantiate the conceptual arguments

Characterizing Strategic Cascades on Networks

Transmission of disease, spread of information and rumors, adoption of new products, and many other network phenomena can be fruitfully modeled as cascading processes, where actions chosen by nodes influence the subsequent behavior of neighbors in the network graph. Current literature on cascades tends to assume nodes choose myopically based on the state of choices already taken by other nodes. We examine the possibility of strategic choice, where agents representing nodes anticipate the choices of others who have not yet decided, and take into account their own influence on such choices. Our study employs the framework of Chierichetti et al. [2012], who (under assumption of myopic node behavior) investigate the scheduling of node decisions to promote cascades of product adoptions preferred by the scheduler. We show that when nodes behave strategically, outcomes can be extremely different. We exhibit cases where in the strategic setting 100% of agents adopt, but in the myopic setting only an arbitrarily small epsilon % do. Conversely, we present cases where in the strategic setting 0% of agents adopt, but in the myopic setting (100-epsilon)% do, for any constant epsilon > 0. Additionally, we prove some properties of cascade processes with strategic agents, both in general and for particular classes of graphs.Comment: To appear in EC 201
