From Utopia to Ecotopia
No full textA closer look to the contemporary world screams out the sturdy interdependence faced by the human societies. Financial, economic, ecological and social crises characterize, on global scale, the current human activities. These problems grew from the failure of strong ideology and political utopias laid down on 20th century. Our work highlights the need of setting a new theoretical framework to overcome these crises through building new experiments of human association and new environmental solutions.
The ultimate challenge relies on managing the complexity of the environment, promoting a new vision for alternative and naturally sustainable collective behaviors. We suggest to approach it merging the ecological perspective envisioned by Naess’s deep ecology with McLuhan’s media theory.
Ecology is the discipline that studies ecosystems and, therefore, nature, while human ecology is the study of ecosystems that include humans. However, the environments inhabited by humans are not merely natural: they are strongly modified by technology.
Furthermore, the technological explosion of the West caused the separation of the domains of nature and technique, creating an opposition between them. We suggest that humanity needs to overcome this dichotomy in favor of a total-field image. Electromagnetic, nuclear and digital technologies are, in fact, more complex forms of adaptation to the environment that render the distinction between the natural and the artificial obsolete.
In addition, recording and real time communication technologies have changed the way we connect to each other and how we relate to the environment. The thinking changes are, in fact, reshaped under the influence of such modifications in the communication systems. In particular, we need to change the models of human collective behavior. One way to pursue this aim implies a rethinking of the role played by each local community: technology offers the possibility for a broader and effective communication. This scenario could favor cooperation through the building of a decentralized network society. Why looking for golden age utopian societies when we can already pursue hi-tech ecotopian communities

Croissance et économie licite, illicite et informelle à Trieste au XVIIIe siècle
No full textAu cours du XVIIIe Siècle, les économies informelles et les conduites illégales contribuèrent de faḉon essentielle à la croissance de Trieste et, dans le mème temps, structurerent en profoneur son éspace économique et social. Afin de expliquer le développement de la ville malgré l'échec de la politique des Hansbourg, le consul vémetien de Trieste écrivit que, parmi les investissements qui bénéficianient aux seules personnes prinées, beaucoup étaient à la charge de l'État. De nombreux projects financés échouèrent ou furent l'occasion de « fraudes » ; et le gens disaient que la moitié des investissements publics ètaient « mangés ». Néanmoins, le consul écrivait aussi qu'on citait ce dicton : « Là où le cytoyen privé dit engraisser le Trésor Public, le prince dit enrichir l' État ». C'est aussi vrai pour le contrabande. dans la deuxième moitié di XIXe siècle, les marchands-entrapreneirs de Trieste devaient encore se Justifier face aux accusations de contrabande internationale. Pourtant, à xette époque, les formes de pouvoirde l' État étaient en train de changer en profounder. Et ces modifications rapides affectaient aussi le contexte loca

No full textStructural and spectroscopic characterization of anorthite synthesized from secondary raw materials
No full textRecycling of secondary raw materials is a priority of waste handling in the countries of the
European community. A virtual secondary raw material of great importance is the product of
the thermal transformation of cement – asbestos. This work illustrates the study of calcination
products obtained starting from the product of the thermal transformation of cement-asbestos
at 1200 °C, added to primary raw materials (kaolin, aluminum hydroxide) and boric acid as
mineralizing agent. The calcination has been conducted at 1200 °C for 1 hour. The
crystallization kinetics has been monitored using in situ high temperature X-ray powder
diffraction. The microscopic characterization of the final product of calcination has been
conducted with SEM and TEM imaging supported by X-ray microanalysis. The structure
refinement was conducted on the powder sample using the Rietveld method. The results are
compared with the spectroscopic characterization including Mössbauer and UV-Vis
spectroscopies. The final product of the calcination is essentially anorthite (about 89 wt%)
with minor spinel (11 wt%). All experimental data converge to support the hypothesis that
the anorthite is stoichiometric, and the small amounts of iron detected (1.32 wt%) is Fe3+
hosted in the structure of spinel
