Harm: The counterfactual comparative account, the omission and pre-emption problems, and well-being

The concept of “harm” is ubiquitous in moral theorising, and yet remains poorly defined. Bradley suggests that the counterfactual comparative account of harm is the most plausible account currently available, but also argues that it is fatally flawed, since it falters on the omission and pre-emption problems. Hanna attempts to defend the counterfactual comparative account of harm against both problems. In this paper, I argue that Hanna’s defence fails. I also show how his defence highlights the fact that both the omission and the pre-emption problems have the same root cause – the inability of the counterfactual comparative account of harm to allow for our implicit considerations regarding well-being when assessing harm. While its purported neutrality with regard to substantive theories of well-being is one of the reasons that this account is considered to be the most plausible on offer, I will argue that this neutrality is illusory

The Nature of Context-Sensitive Solutions, Stakeholder Involvement and Critical Issues in the Urban Context

Over the last several decades many transportation and planning agencies have experienced conflicting demands emerging from the need to develop projects in an expeditious manner while at the same time involving stakeholders in the decision-making process, which sometimes is perceived as slowing project delivery and/or increasing costs. Given this tension between apparently conflicting demands, it is important to understand how the stakeholder involvement is being carried out and what best practices may be recommended. This study examines the issue in the context of a relatively new policy framework – Context Sensitive Solutions (CSS) – which supports the early integration of stakeholders into the planning process. The report pays particular attention to stakeholders’ involvement in projects within urban centers, where there is likely to be more complexity, both in terms of the number of stakeholders and end users affected. CSS is a relatively new process and not consistently interpreted or applied across states and/or agencies. The literature suggests that an underlying assumption when applying CSS principles to community involvement processes is that stakeholders are empowered through clear policies and procedures directed towards their participation. In our research, we found that the extent to which public agencies apply the CSS framework and involve and respond to stakeholders depends on each agency\u27s interest to engage the public in the deliberation process to find the best-fit project for a community. It is likely that the increased integration of stakeholders into the planning and project development process will not become a state of practice until the benefits flowing from community involvement are clearly understood by the agency staff. The CSS literature describes many benefits associated with comprehensive stakeholder engagement, including gaining constituents\u27 buy-in and support for project financing. A movement toward standardizing CSS policies and directives across the country will facilitate a public discussion about the benefits of engaging communities into the project design phase and away from solely expert-based designs. In addition, there are a number of stakeholder involvement practices that, if adopted, could expedite the integration of communities\u27 views and values in the decision-making process, while at the same time minimizing the chances of protracted consultation processes, time delays and additional costs

Compositional Morphology for Word Representations and Language Modelling

This paper presents a scalable method for integrating compositional morphological representations into a vector-based probabilistic language model. Our approach is evaluated in the context of log-bilinear language models, rendered suitably efficient for implementation inside a machine translation decoder by factoring the vocabulary. We perform both intrinsic and extrinsic evaluations, presenting results on a range of languages which demonstrate that our model learns morphological representations that both perform well on word similarity tasks and lead to substantial reductions in perplexity. When used for translation into morphologically rich languages with large vocabularies, our models obtain improvements of up to 1.2 BLEU points relative to a baseline system using back-off n-gram models.Comment: Proceedings of the 31st International Conference on Machine Learning (ICML

Extreme ultraviolet emission lines of Ni xii in laboratory and solar spectra

A linear force-free field solution is presented in cylindrical coordinates, formulated in terms of trigonometric and Bessel functions. A numerical exploration has revealed that this solution describes magnetic field lines that meander in Cartesian space, as well as field lines that lie on toroidal flux surfaces. These tori are in (or close to) the plane perpendicular to the cylindrical axis. Nested tori, as well as tori with shells that have finite thickness, were found. The parameter space of the solution shows that the tori exist within a bounded range of values

A new family of solutions of the force-free field equation

A new family of solutions has been found for force-free magnetic fields and Beltrami flows, which admits a complete classification in terms of the eigenvalues of the problem. In the absence of boundary values to determine them uniquely, the eigenvalues correspond to the entire set of real numbers, except for zero. The eigenvalues are degenerate in that each eigenvalue has many eigensolutions associated with it. For each eigensolution we have been able to identify sets of equilibrium or null points and lines. The linear mappings of these null points and lines are all unstable. Finally, we derive the first integral of energy associated with this family of solutions

The Level of Information Systems Integration in Romania

Integration is an activity that unites people, equipments, programs but also managerial practices and helps a company to put its knowledge into good use. In Romania, more and more private companies choose to have integrated systems to help them grow. Public owned companies and institutions, for example The National House of Pensions and Other Social Insurance Right, invested large amounts of founds in the development of new information systems to help them gather, process and disseminate data from the population.integration, information systems, standards, data integration, application integration

Nonaxisymmetric instabilities of convection around magnetic flux tubes

On the surface of the Sun, magnetic flux elements collect in regions of converging flow, grow in field strength and become pores, which have been observed to exhibit nonaxisymmetric structure over a range of scales. Around a fully developed sunspot, as well as the fine scale of the penumbra, the moat sometimes shows clearly observable spoke-like structure at low azimuthal wavenumbers. We investigate the formation of azimuthal structure by computing the linear stability properties of fully nonlinear axisymmetric magnetoconvection, which takes the form of a central flux tube surrounded by a convecting field-free region. We find steady and oscillatory instabilities with a preferred azimuthal wavenumber. The unstable modes are concentrated in the convecting region close to the outer edge of the flux tube. The instability is driven by convection, and is not a magnetic fluting instability
