    How explicit are the barriers to failure in safety arguments?

    Safety cases embody arguments that demonstrate how safety properties of a system are upheld. Such cases implicitly document the barriers that must exist between hazards and vulnerable components of a system. For safety certification, it is the analysis of these barriers that provide confidence in the safety of the system. The explicit representation of hazard barriers can provide additional insight for the design and evaluation of system safety. They can be identified in a hazard analysis to allow analysts to reflect on particular design choices. Barrier existence in a live system can be mapped to abstract barrier representations to provide both verification of barrier existence and a basis for quantitative measures between the predicted barrier behaviour and performance of the actual barrier. This paper explores the first stage of this process, the binding between explicit mitigation arguments in hazard analysis and the barrier concept. Examples from the domains of computer-assisted detection in mammography and free route airspace feasibility are examined and the implications for system certification are considered

    The New Politics of Linkage: India\u27s Opposition to the Worker\u27s Rights Clause

    Get PDF
    This article examines why India has opposed a World Trade Organization (WTO) workers\u27 rights clause, and calls for a new way of thinking about international institutions and the link between trade and labor rights. Many labor rights supporters argue that labor rights principles should be integrated into the WTO, either via the addition of a workers\u27 rights clause or through a \u27judicial reading of labor rights values into the existing WTO framework. But India has led a large block of developing countries in opposing any link between labor rights and the WTO. This opposition has been based primarily on economic arguments that suggest linkage is motivated by protectionism, concerns about political sovereignty and neocolonialism, and structural arguments about the proper institutional roles of the ILO and WTO. These arguments, it is suggested, must be understood in both a contemporary and historical context. In light of this opposition by developing countries, the article proposes a transition from a WTO-centered view of trade and labor linkage o a paradigm based on bilateral and regional market-based agreements that utilize the ILO\u27s model that would engage more dynamically with the concerns presented by India and other stakeholders in the developing world.

    Measuring Multijet Structure of Hadronic Energy Flow Or What IS A Jet?

    Get PDF
    Ambiguities of jet algorithms are reinterpreted as instability wrt small variations of input. Optimal stability occurs for observables possessing property of calorimetric continuity (C-continuity) predetermined by kinematical structure of calorimetric detectors. The so-called C-correlators form a basic class of such observables and fit naturally into QFT framework, allowing systematic theoretical studies. A few rules generate other C-continuous observables. The resulting C-algebra correctly quantifies any feature of multijet structure such as the "number of jets" and mass spectra of "multijet substates". The new observables are physically equivalent to traditional ones but can be computed from final states bypassing jet algorithms which reemerge as a tool of approximate computation of C-observables from data with all ambiguities under analytical control and an optimal recombination criterion minimizing approximation errors.Comment: PostScript, 94 pp (US Letter), 18 PS files, [email protected]

    Towards a clearer delimitation of internal European Community competences.

    Get PDF
    This thesis is a study of the distribution of competences between the main actors in European integration: namely the European Community and the Member States. It aims to evaluate the place of the competence provisions in the current Treaty structure as well as within the Treaty Establishing a Constitution for Europe. This task first involves a legal-technical exercise based on a textual interpretation of different categories of competences within the above-mentioned sources. Second, it involves a review of the relevant Court of Justice case law with regard to those competences. The study of both has led the author to consider how the evolution of Community competence has given rise to the phenomenon of 'competence' creep'. It is argued that Member States contend that the Community assumes more powers than those it possesses. Thus, the thesis provides an insight into concerns about 'creeping competence'. Certain types of situations are identified under the title of 'creeping competence'. These include, the adoption of unjustified or undesired EC legislation under qualified majority voting the expansion of the Community's competence under Article 308 EC and finally the adoption of EC legislation that goes beyond the scope of Article 5 EC (principle of attribution of powers). The thesis will provide certain examples to underline the problem. It will take account of the use of the flexibility provisions of Article 95 EC and 308 EC with regard to the regulation of health and the Community's accession to the European Convention of Human Rights (ECHR), which are treated as case studies in the thesis. In the context of a problematic system of competences, the author will consider the assumptions made in the Nice and Laeken IGCs as well as the European Convention for a clearer distribution of competence and assess the role of the principle of subsidiarity as a tool against the expansion of Community competence into new policy areas. It is argued that the reform of subsidiarity will enhance EU legitimacy and enlarge the role of national legislatures in the Union. The reconstruction of subsidiarity procedures may remedy the tensions in the current system of competence and provide limits to the degree of EU intervention. Besides tidying up competences between the EU and Member States, European Constitutionalisation hides a question of political finality and further integration. How can the EU establish an effective and democratically legitimate governance beyond the Nation State Via a European Constitution or through alternative methods This question is particularly important in the current context following the French and Dutch rejection of the EU Constitutional Treaty. The chances of the EU Constitution being revived in the near future are slim, since it is unlikely that either France or Holland will soon hold another referendum. Thus, either a period of reflection shall be allowed to Member States or alternative routes to integration shall be considered. The thesis concludes with the hypothesis that as the EU Constitutional Treaty does not provide the answers to most of the questions posed by the Nice and the Laeken European Councils, enhanced cooperation may be utilised as a future method of governance and Fischer's 'Core Europe' as a tool capable of a redistribution of competences inside the Union. But then again the European Union needs to avoid a new iron curtain descending between those Member States that represent the 'core' and those that constitute the 'periphery'

    Designing Arguments for Academic, Public, and Professional Audiences

    Get PDF
    This college-level textbook guides students through five different types of arguments: evaluations, responses, persuasive rhetorical arguments, proposals, and practical professional development arguments. Students are introduced to rhetorical concepts and strategies to enable them to more effectively appeal to different types of audiences. Students will gain practice in audience-based reasoning, basing their reasons and evidence on the assumptions, beliefs, and values of their readers.https://newprairiepress.org/ebooks/1040/thumbnail.jp
