LE DETERMINANTI DELLA CREAZIONE DI SPIN-OFF ACCADEMICI. IL CASO DELL’UNIVERSITÀ DI FERRARA
No full textQuesto lavoro svolge un’analisi empirica sulle motivazioni che portano lo scienziato
ad intraprendere la creazione di impresa o la partecipazione come manager
in una nuova impresa. L’intenzione è quella di meglio comprendere le interdipendenze
tra i vari incentivi riconosciuti in letteratura che spingono il
ricercatore accademico a dedicare parte del proprio tempo al fine di apportare
le proprie competenze in ambito industriale attraverso la nascita di
nuove realtà imprenditoriali. L’analisi viene svolta sull’Università di Ferrara

Objective: Blowout fractures of orbital bone may be cause of important facial asymmetry . Significant complications can occur as a result of these injuries, including enophthalmos, persistent diplopia, vertical dystopia, and restriction gaze. Recommendation for surgical fracture repair depend on a combination of clinical and imaging studies to evaluate the muscle and the nerve entrapment and periorbital tissue herniation. There are many techniques and biomaterials for reconstructing the original bony contour and restoration of proper orbital volume. Often a second surgery intervention may be required to solve the clinical case.
Methods: A male 21 -year-old patient suffered frontal anterior cranial vault injuries and facial pan trauma. A first surgical intervention was performed to fracture reduction of frontal bone and zygomatic suture, supraorbital reconstruction with frozen bone, orbital floor reconstruction with durapatch membrane and reduction of maxillo-zygomatic process on the left. Reduction of frontal bone and zygomatic fracture, orbital floor and medial orbital frame reconstruction on the right. Than the patient’s anatomy was assessed in multiplanar (axial, coronal, sagittal) and 3D computed tomography. Stock titanium mesh was then preformed to the stereolitographic model to reproduce optimal orbital contour. A second surgical intervention was performed after 6 months to resolve left diplopia and the facial asymmetry of the patient. The orbital floor on the left was 7,4mm deeper than contralateral one. An orbital floor reconstruction with iliac crest graft bone was performed. A 1,5cm length and 1,2 deep graft bone was shaped and fixed with titanium mesh plate and screws.
Result: Preoperative computer modeling provides useful guide for and presumably more accurate reconstruction of complex orbital injuries.
Conclusions: The combined use bone grafts of titanium mesh plate could be an effective technique for the orbital floor reconstruction in severe asymmetry
Research topics in crop diversification at the landscape level
No full textCrop diversification has many benefits both at the cropping system and the food system levels and has
been addressed in agricultural research (Hufnagel et al., 2020). Landscape design and management in
agricultural regions can support crop diversification by building bridges with scientific domains like
ecology and geography (Benoit et al., 2012). Though, little is known on how the research community has
addressed crop diversification from a landscape perspective. In this paper we investigated a
bibliographic corpus retrieved from the Scopus database papers coupling crop diversification and
landscape (in title, abstract and keywords), retrieving 461 papers for the period 1990 to 2020. The
corpus was analysed using the CorText platform (e.g., Ruiz-Martinez et al., 2015). First, natural language
processing was used to extract multi-terms from title, abstract and keywords. Then, we mined the
temporal dynamics and co-occurrence of the 100 most frequent terms. Our findings showed that
species richness emerges as the main topic in this corpus and that natural enemies, crop types and
natural control increased in importance. In the last years, genetic diversity, climate change and
agricultural production also gained attention. On the contrary, land use and some of the terms related
to diversity (landscape, plant and farmland) were marginal or decreasing. By analysing the terms cooccurrence on the three decades, we observed that the papers addressing crop varieties and
agroforestry system split into two streams: one about agricultural production in relation to climate
change and the other about farm size and land use. Instead, the functional diversity and field margin
disappeared from recent literature. Land use patterns and landscape diversity converged mainly on
studies about biological pest control. Altogether, the corpus highlighted that the spatial configuration
lost importance when addressing crop diversification. In addition, the species diversity gained attention
finally catching a large part of the literature in the corpus. From a landscape approach perspective, we
might point out the apparent lack of a major topic: the involvement of local communities and
stakeholders. Our simple and rapid text mining approach yielded early evidence of knowledge gaps
about the landscape level in crop diversification literature. The expected contribution of approaching
the crop diversification at the landscape level would be to provide a relevant framework for the
characterisation of the baseline system to be diversified. In particular, the landscape agronomy
perspective stressed the need to define the scale and target area for crop diversification consistently
with (natural and cultivated) species diversity embedded in a local socio-technical system
