Texte intégralThe aim of this thesis is to study the complex relationship between scientific productivity and (formal and informal) scientific collaborations. We follow an approach which goes beyond the classical trade-off that emerged from the literature around networks studies and game theory, in the attempt of developing a synthesis between a micro and a macro approach. In doing so, we enrich the toolset of available methodologies by adopting instruments which are typical of Network Analysis (e.g.: networks’ indices of centrality and clustering), Econometrics (e.g.: ZIP and Censored regressions), and Experimental Economics (e.g.: Laboratory experiments). In particular, we look at two different scientific communities, in order to capture different characteristics of the networks: the community of Top geographers, and the community of Italian economists. This thesis is structured with a view to emphasising the role that the incentives which move scientists within their network of collaboration play on shaping the network itself, but also on influencing their scientific productivity. The thesis is composed of three different essays, each of which approaches the phenomena of scientific production and collaboration from different perspectives, allowing me to highlight the role played by four basic components (i.e.: networks, scientific communities, collaborative behaviours, individual incentives and collective outcomes) in shaping the structure and dynamics of the “world of science”.

Texte intégralThe impact of waves caused by storm surges could lead to significant damage to coastal bridges’ substructure. As well, also piers of river-crossing structures have shown an often worrying level of vulnerability due to flooding wave impact. The knowledge of the mechanisms characterizing the interaction wave-flow-structure plays a key role in better design of coastal and fluvial bridges. Several studies have documented that hydraulic forces add significant hydrodynamic loads on structures built in fluvial and marine environment. As well, the modifications induced by the vertical structures of the bridge on the downstream flow during the transit of a long wave and the generation of coherent turbulent eddies from the structure deserve further research, considering that they could affect sediment and ecosystem downstream. For these purposes, the joint use of experimental and numerical analysis is a useful method for studying the complex behaviour of the wave superimposed to a steady flow in presence of a structure. The aim of this study is to develop small-scale laboratory and numerical models to examine the hydrodynamic behaviour of long waves released on a shallow current when impacting vertical rigid cylinders. The experimental model reproduces the propagation of two long waves in a flume, characterized by different values of flow rate and wave height, overlapped on a uniform base flow, in the presence of two rigid vertical cylinders simulating the bridge’s piers. The velocity measurements, obtained with a PIV (Particle Image Velocimetry) system on 2D planes, are firstly used to define the typology of the selected waves from an analytical point of view. Then, they are examined: i) upstream the cylinders, to depict the time-varying vertical distributions of the drag and inertia forces acting on the cylinders during the transit of the wave; ii) downstream the cylinders to obtain the time-varying velocity and vorticity maps in a horizontal plane; iii) by applying the continuous wavelet technique to detect the presence of coherent turbulent eddies downstream the vertical obstructions, evolving during the wave transit. The main experimental findings highlight that the drag force is the prevalent contribution acting on the cylinder during the whole wave transit, reaching a maximum value at the wave crest. Downstream each cylinder, a shadow zone is evident, as expected, as well as detaching vortexes in the cylinder’s wake. Finally, using the continuous wavelet technique, the presence of coherent turbulent eddies in some target points of the cylinder’s wake is assessed, providing some useful information about the turbulent lengths scales and the frequency of such coherent structures, also depending on the wave phase. As for the numerical aspect, two numerical simulations with the olaFlow solver are executed to reproduce the experimental model. For each wave, the time-varying velocity profiles during the wave transit and the velocity and vorticity horizontal fields downstream the cylinder are investigated. In this way it is possible to compare the numerical results with the experimental ones, in order to validate the numerical model. Generally, the estimated relative errors between experimental data and numerical outputs reveal a better performance of the model upstream the cylinders in the vertical plane, while we observe a lower capability of the model to reproduce the flow field downstream the cylinders, especially in their wakes, thus requiring further future research.
