R.S. Peters' Comprehensive Theory of Moral Education
No full textThis article presents R.S. Peters’ theory of moral education embedded in his broad conception of morality. The author examines Peters’ views against the background of Kohlberg’s stage theory of moral development; hence, the positions of both thinkers are interwoven throughout the discussion. It addresses some central issues relevant to moral education such as, for example: cognitive and affective aspects of morality, and the acquisition of virtues. In the article the author argues that Peters’ account of moral development and moral education provides supplementation for the somewhat narrow theory developed by Kohlberg, thus establishing a broader framework relevant to moral education.status: Publishe

No full textThe development of Integrated Circuits for the Automotive sector imposes on complex challenges. ISO26262 Functional Safety requirements entail extensive Fault Injection campaigns and complex analysis for the evaluation of deployed Software Tools. This paper proposes a methodology to improve Fault Analysis Tools Confidence Level (TCL) by detecting errors in the classification of faults. By combining the strengths of Automatic Test Pattern Generators (ATPG), Formal Methods and Fault Injection Simulators we are able to automatically generate a Test Environment that enables the validation of the tools and provides supplementary information about the design behavior. Our results showed fault detection rates above 99% including information to improve ISO26262 metrics calculationAccepted author manuscriptComputer EngineeringQuantum & Computer Engineerin
Transition and wavy walls: an experimental study: An experimental study
No full textA wide body of research exists which explores the effects of surface roughness or patterned wall shapes on instability growth and transition. Building on those works as well as recent experiments demonstrating passive laminar flow control using arrays of discrete roughness [3, 8], a set of spanwise-wavy walls is designed with the goal of suppressing instability growth in two-dimensional boundary layers. In a numerical investigation of Tollmien-Schlichting (TS) wave growth in the presence of streamwise boundary-layer streaks, Cossu and Brandt [1] found that stabilization of TS waves results from spanwise shear in the mean flow, which forms a negative contribution to production in the perturbation kinetic energy equation. Whereas previous efforts have employed streamwise vorticity developing in roughness wakes to provide the requisite mean-flow deformation, in this work stabilization is achieved through modulation of the no-slip surface. Miniature vortex generators (MVGs) have proven an effective means of producing streamwise streaks for transition delay [8], though relatively large streak amplitudes are necessary to counter their eventual decay through viscous dissipation. The notion motivating this work is that spanwise-wavy walls extended in the streamwise direction can produce a similar effect while avoiding bypass transition resulting from large-amplitude streamwise streaks. Toward that end, six wavy walls are used in a modular test model. When TS waves are excited upstream of the wavy walls, substantial delays in the onset of transition are observed for certain spanwise wavelengths compared with the flat-plate reference case
Milczące życie liter. O związku języka i przyrody w poezji R.S. Thomasa
Full text linkJoanna SoćkoSilent Life of Letters. On Interconnections between Language and Nature in the Poetry of R.S. Thomas.The essay sets out to explore R.S. Thomas’ (1913–2000) vision of the problematic relations between the man, the nature and their Creator. In the context of contemporary critique as well as the 20th century, post-husserlian philosophy, the author analyses Thomas’ cosmological poems and represents, on the one hand, the place that both man and God take in the creation and, on the other, the sacramental relationship between the human and the nature. What is important from this perspective is the material existence of both man and nature, which enables mutual infiltration that leads to discovery of imperceptible dimension of materiality, which, in turn, influences both human consciousness and language. This is why the author asks about the role of science in Thomas’ poetry and about the influence that “the machine” has on language and consciousness.Joanna SoćkoSilent Life of Letters.
