Le briofite della Grotta dell\u2019Orso (33-7VG, Carso triestino, NE Italia)
Vengono presentati i risultati di uno studio sulla flora briologica della Grotta dell\u2019Orso (33-7VG), situata sul Carso triestino. Sono state rinvenute 42 specie di briofite (33 specie di muschi e 9 epatiche); per ogni specie sono indicati l\u2019elemento corologico, la distribuzione nell\u2019area e note ecologico-stazionali. Aspetti floristici, biogeografici e conservazionistici della componente briologica dell\u2019area vengono discussi. Viene riportata una nuova specie per la Regione Friuli Venezia Giulia, l\u2019epatica Cololejeunea rossettiana; 2 altre specie di muschi sono segnalate come nuove per il Carso. La flora briologica aggiornata della cavit\ue0 comprende 46 specie
Strategic environmental assessment implementation of transport and mobility plans. The case of italian regions and provinces
Transport and mobility plans imply strategies and actions that affect the environment. The European Union has introduced in 2001 the strategic environmental assessment (SEA) to take into account and mitigate adverse environmental effects in planning and decision-making.
SEA limited implementation has attracted the interest of many scholars that have sought methods able to assess the quality of SEA processes by identifying vices and virtues in practice. In this paper, we measure the quality of eight SEAs for transport and mobility plans of regional and provincial administrations of Italy. Results show that the overall quality level of SEA reports is only barely sufficient, Abruzzo is among the virtuous and Piedmont among the critical administrations.
We also stress that the determination of impact significance has received the worse quality score. We finally compare our results to other Italian and British homologous cases finding interesting and generally confirmative evidence

An Analysis of Settlement Risk Contagion in Alternative Securities Settlement Architecture
This paper compares the so-called gross and net architectures for securities settlement. It studies the settlement risk arising from exogenous operational delays and compares the importance of settlement failures under the two architectures, as a function of the length of the settlement cycle and of different market conditions. Under both architectures, settlement failures are non-monotonically related to the length of settlement cycle. There is no evidence that continuous time settlement provides always higher stability. Gross systems appear to be more stable than net systems
Binge eating disorder In adolescence: the role of alexithymia and impulsivity
Binge Eating Disorder (BED) is a disorder, recently included in DSM-5, often present in adolescence. Several studies highlight that adolescents with BED had high levels of impulsivity and alexithymia. Even though studies have underlined the importance of these variables, no studies have investigated their role on adolescents’ emotional-behavioral functioning. This study proposes to verify if adolescents affected by BED show higher levels of alexithymia and impulsivity than adolescents without diagnosis, and what is their role on adolescents’ emotional-behavioral functioning. Thanks to the collaboration with clinical centers for eating disorders, a group composed by 60 adolescents diagnosed with BED was paired to a 60 healthy controls. Participants completed validated self-report questionnaires investigating levels of alexithymia, impulsivity and emotional-behavioral functioning. Adolescents diagnosed with BED showed higher scores on alexithymia, impulsivity and maladaptive emotional-behavioral functioning than healthy controls. Moreover, alexithymia had a mediating effect on the relationship between impulsivity and emotional-behavioral functioning. These results show that alexithymia is a key variable influencing the emotional-behavioral functioning of adolescents affected by BED. Further studies are needed to also check other variables that might lead to the onset of BED. On the other hand, our findings can help clinicians suggesting the importance of promoting prevention and treatment polices focused on alexithymia
The Hodge numbers of O'Grady 10 via Ng\^o strings
We determine the Hodge numbers of the hyper-K\"ahler manifold known as
O'Grady 10 by studying some related modular Lagrangian fibrations by means of a
refinement of the Ng\^o Support Theorem.Comment: Revised and final version to appear in Jour. Math. Pur. et App
MHD THREE-DIMENSIONAL STAGNATION-POINT FLOW OF A MICROPOLAR FLUID
The steady three-dimensional stagnation-point flow of an electrically conducting micropolar fluid in the absence and in the presence of a uniform external electromagnetic field (E0,H0) is analyzed and some physical situations are examined.
In particular, we proved that if we impress an external magnetic field H0, and we neglect the induced magnetic field, then
the steady MHD three-dimensional stagnation-point flow of such a fluid is possible if, and only if, H0 has the direction parallel to
one of the axes.
In all cases it is shown that the governing nonlinear partial differential equations admit similarity solutions. Moreover in the presence of an external magnetic field H0, it is found that the flow of a micropolar fluid has to satisfy
an ordinary differential problem whose solution depend on H0 through the Hartmann number M.
Finally, the skin-friction components along the axes are computed
Complex networks analysis in socioeconomic models
This chapter aims at reviewing complex networks models and methods that were
either developed for or applied to socioeconomic issues, and pertinent to the
theme of New Economic Geography. After an introduction to the foundations of
the field of complex networks, the present summary adds insights on the
statistical mechanical approach, and on the most relevant computational aspects
for the treatment of these systems. As the most frequently used model for
interacting agent-based systems, a brief description of the statistical
mechanics of the classical Ising model on regular lattices, together with
recent extensions of the same model on small-world Watts-Strogatz and
scale-free Albert-Barabasi complex networks is included. Other sections of the
chapter are devoted to applications of complex networks to economics, finance,
spreading of innovations, and regional trade and developments. The chapter also
reviews results involving applications of complex networks to other relevant
socioeconomic issues, including results for opinion and citation networks.
Finally, some avenues for future research are introduced before summarizing the
main conclusions of the chapter.Comment: 39 pages, 185 references, (not final version of) a chapter prepared
