Some forty years on from the great events of the Second Vatican Council, there is still much debate about the interpretation of the Council and its documents. In recent years there has been what might be termed a hermeneutical project: to develop an understanding of the complex processes involved in the genesis of the texts and to explore the interactions of the various individuals and groups that helped to shape the Council. What has emerged is a view of the Council (...) as something organic and dynamic. This article seeks to outline the questions that this hermeneutical project has raised; such as the various sources that can be used to interpret the Council, the impact of various theological strands of tradition present at the Council, the authorship of the texts and the methodologies adopted by the Council. It also provides a review of the work that has taken place with this project, especially in the last ten years or so. (shrink)
Associative learning is an essential feature of human cognition, accounting for the influence of priming and interference effects on memory recall. Here, we extend our account of associative learning that learns asymmetric item-to-item associations over time via experience by including link maturation to balance associations between longer-term stability while still accounting for short-term variability. This account, combined with an existing account of activation strengthening and decay, predicts both human response times and error rates for the fan effect for both target (...) and foil stimuli.

We present a spatial system called Specialized Egocentrically Coordinated Spaces embedded in an embodied cognitive architecture (ACT-R Embodied). We show how the spatial system works by modeling two different developmental findings: gaze-following and Level 1 perspective taking. The gaze-following model is based on an experiment by Corkum and Moore (1998), whereas the Level 1 visual perspective-taking model is based on an experiment by Moll and Tomasello (2006). The models run on an embodied robotic system.
Koonin argues that CRISPR-Cas systems present the best-known case in point for Lamarckian evolution because they satisfy his proposed criteria for the specific inheritance of acquired adaptive characteristics. We see two interrelated issues with Koonin’s characterization of CRISPR-Cas systems as Lamarckian. First, at times he appears to confuse an account of the CRISPR-Cas system with an account of the mechanism it employs. We argue there is no evidence for the CRISPR-Cas system being “Lamarckian” in any sense. Second, it is unclear (...) whether the mechanism is more “Lamarckian” than many other forms of genetic change already well-characterized in Darwinian terms. We present three conceptually distinct senses in which the mechanism of IAC may be considered Lamarckian and argue that only the strongest sense of goal-directed IAC would be difficult to accommodate in a Darwinian account. As the CRISPR-Cas mechanism does not qualify as “Lamarckian” in this strong sense, we argue there is no conceptual value in calling it “Lamarckian”. Finally, we suggest that CRISPR-Cas systems do hold the potential for genuinely non-Darwinian, directed evolution in a way that Koonin did not discuss, involving their potential use as a human gene-editing tool.

"Joseph Marechal, who became one of the most important figures in the twentieth-century revival of the thought of St. Thomas Aquinas, set for himself an ambitious intellectual project. His goal was to demonstrate that the realist theory of knowledge first enunciated by Aristotle in the ancient world and developed by Aquinas in the thirteenth century is the key to a coherent philosophy of man and being. According to Marechal, once late medieval philosophy moved away from Aquinas's epistemological foundations, no longer (...) could it construct a satisfactory unity of knowledge, man, and being. Thus modern Western philosophers, specifically Descartes, began their quest to elaborate an adequate intellectual account of human experience on the basis of a flawed philosophical legacy."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

The prevailing economic paradigm, in which a closed circular flow of production and consumption can be described in terms of 'natural laws ' of the equilibrium of market forces, is being challenged by our growing knowledge of complex systems, particularly ecosystems. It is increasingly apparent that neo-classical economics does not reflect social, economic and environmental realities in a world of limited resources. The best way to understand the problems implicit in the concept of 'sustainable development ' is provided by Ecological (...) Economics – a new synthesis in which the traditional virtue of thrift is justified using modern ideas from systems theory and thermodynamics. (shrink)
