Modeling Cognitive Social Capital and Corporate Social Responsibility (CSR) as Preconditions for Sustainable Networks of Relations
No full textThe paper studies the relationship between social capital (SC) and Corporate Social Responsibility (CSR) by investigating the idea of a virtuous circle between the level of SC and the implementation of CSR practices that favours the creation of cooperative networks between the firm and all its stakeholders by promoting the spread of social norms of trust, trustworthiness and cooperation.
Following the literature on SC that stresses its multidimensional character (e.g. Paldam 2000), we consider two dimensions of this notion. Starting from the distinction introduced by Uphoff (1999), we take into account a cognitive and a structural idea of SC. The first one essentially refers to the dispositional characters of agents that affect their propensity to behave in different ways. The latter refers to social networks connecting agents.With regard to the concept of CSR, we adopt a contractarian approach and consider CSR as an extended model of corporate governance, based on the fiduciary duties owed to all the firm's stakeholders. Among stakeholders, we distinguish between strong and weak stakeholders. Both these two categories have made specific investments in the firm. However, strong stakeholders are precious for the firm because they bring in strategic assets. They are, for example, skilled workers or institutional investors. On the contrary, weak stakeholders do not bring strategic assets into the firm and firms have material incentives at defecting in the relationship with them. They are, for example, unskilled workers.
By using the tools of psychological game theory, the paper shows the role of cognitive social capital and the adoption of CSR practices in promoting the emergence of social norms of trust, trustworthiness and cooperation which favour the creation of cooperative networks between the firm and all its stakeholders (structural social capital).
In particular, we show that: a) the level of cognitive SC plays a key role in inducing the firm to adopt and observe CSR practices that respect all the stakeholders; b) the decision of adopting formal instruments of CSR contributes to create cognitive SC that is endogenously determined in the model; c) the level of cognitive SC and the decision of adopting CSR practices creates structural SC in terms of a long term relationship between the firm and the weak and strong stakeholders.
Outer layer turbulence intensities in smooth- and rough-wall boundary layers
No full textClear differences in turbulence intensity profiles in smooth, transitional and fully rough zero-pressure-gradient boundary layers are demonstrated, using the diagnostic plot introduced by Alfredsson, Segalini & Örlü (Phys. Fluids, vol. 23, 2011, p. 041702) – u?/U versus U/Ue, where u? and U are the local (root mean square) fluctuating and mean velocities and Ue is the free stream velocity. A wide range of published data are considered and all zero-pressure-gradient boundary layers yield outer flow u?/U values that are roughly linearly related to U/Ue, just as for smooth walls, but with a significantly higher slope which is completely independent of the roughness morphology. The difference in slope is due largely to the influence of the roughness parameter (?U+ in the usual notation) and all the data can be fitted empirically by using a modified form of the scaling, dependent only on ?U/Ue. The turbulence intensity, at a location in the outer layer where U/Ue is fixed, rises monotonically with increasing ?U/Ue which, however, remains of O(1) for all possible zero-pressure-gradient rough-wall boundary layers even at the highest Reynolds numbers. A measurement of intensity at a point in the outer region of the boundary layer can provide an indication of whether the surface is aerodynamically fully rough, without having to determine the surface stress or effective roughness height. Discussion of the implication for smooth/rough flow universality of differences in outer-layer mean velocity wake strength is include

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Money and finance: the heterodox views of R. Clower, A. Leijonhufvud and H. Minsky
No full textThe heterodoxy of Robert Clower, Axel Leijonhufvud and Hyman Minsky consisted in dispensing with the dominant assumption according to which the system spontaneously tends to a situation of full coordination. In analysing the effective disequilibrium behaviour of the system, all three came to the conclusion that monetary and financial forces have a crucial importance for coordination and that their role can be highly destabilising. Contrary to the dominant theory, all three offer useful insights to understand what is happening today.

VII, p. 777-779.(Fragment inédit) Il y a quelques jours, M. Villemain, esquissant à grands traits le caractère du Dante, appelait sur ce singulier génie l’attention de la jeunesse de nos écoles, et presque au même moment on lisait dans plusieurs salons des fragments d’une traduction en vers de la Divine Comédie. C’est le début d’un j..
