Coordination: A model-theoretic perspective
A learning to coordinate paradigm was first introduced in Formal Learning Theory by (Montagna & Osherson, 1999) using the tools of recursion theory. In this paper, we advance and discuss a first-order paradigm of coordination - we call this paradigm of model-coordination. The paradigm is shown to extend Montagna and Osherson's binary players coordinate and if and only if their first-order equivalent agents model-coordinate. An important difference between or paradigm and the proposed by (Montagna & Osherson, 1999) is that in our paradigm agents' preferences and beliefs can be modelle

Selvicoltura nei boschi di montagna
Il rapporto finale sul progetto di selvicoltura di montagna realizzato dalla Confederazione dal 1980 al 1987 e apparso per la prima volta nel 1987 è ormai disponibile in italiano. Esso si rivolge ai servizi forestali a tutti i livelli, allo scopo di offrire loro basi decisionali e materiale di sostegno al loro perfezionamento nell'ambito della gestione delle foreste di montagna, secondo il principio della continuità. La guida offre metodi di lavoro per l'impianto di foreste in stazioni estreme, per la cura e la rinnovazione di foreste di montagna tipiche e di soprassuoli in trasformazione. Contiene anche conoscenze di dettaglio e suggerimenti pratici per l'attività del servizio forestale di montagna

Vecchia e nuova ruralità nella montagna lombarda
Nel presente contributo si analizzano i fattori storico-geografici e socio-economici che negli ultimi decenni hanno investito gli spazi rurali della montagna lombarda. Tali fattori hanno avviato dinamiche di contrazione per la base produttiva agro-silvo-pastorale, erosione della superficie utilizzata, diminuzione delle dimensioni medie delle aziende presenti sul territorio. Il marcato esodo rurale, l''abbandono delle pratiche conservative dell''ambiente, la fragilità del ciclo degli investimenti e la scarsa specializzazione delle produzioni completano la gamma piuttosto vasta di problematiche che coinvolgono la montagna lombarda. A questa marginalità e debolezza si cerca di rispondere con nuove forme di ruralità, diversi criteri di pianificazione, politiche inedite di sostegno, l''adozione di più adeguati strumenti, l''avvio di procedure non tradizionali

All paratypes with our label: Pachybrachis holerorum n. sp. paratypus Montagna & Sassi des. [red, printed]. Paratypes in MSNM, DSPC, MMPC, MSPC, MDPC. Etymology. The name is genitive plural of holus, used by the Roman poet Lucilius to indicate leguminous forbs. Description of male. Total length: male = 2.9 ± 0.1 mm. Head yellow except vertex, a median longitudinal stripe with bifurcated apex along frons, antennae sockets, anterior margin of clypeus black. Frons shining, covered with fairly impressed punctation, denser on clypeus and above insertion of antennae, sparser on frons. Antennae filiform, brownish, segments 1–5 partly yellowish. Pronotum black with yellow bands along anterior and lateral borders; anterior band lightly thickened at anterior angles and with short median posteriorly directed vitta; two anteriorly directed yellow lines from basal margin at sides of scutellum, 1.5 times wider than long, regularly curved at sides, with maximum width at about middle; punctation deep, denser at sides, slightly sparser on disc. Scutellum elevated, black, minutely punctate, apically truncate. Elytra coarsely punctured, partially arranged in striae; interstices raised, black with yellow pattern slightly raised from black surface, arranged as follows (spots and vittae may be interrupted or absent): narrow bands and vittae along anterior, lateral and posterior margins; narrow vitta along posterior half of sutural margin; two elongated spots near suture, plus one behind scutellum and one larger, in median position; longitudinal vitta on anterior margin lateral to humeral callus; post-median spot on disc; several smaller spots variously arranged on elytral surface. Epipleura black in posterior half, partly yellow anteriorly, with one or two series of irregularly aligned punctures on edges. Venter black, mesepimera with yellow spot, sometimes indistinct. Abdominal ventrites sparsely punctured and covered with rather sparse, long whitish hairs; ventrite 5 with shallow depression, glabrous. Legs yellow, fore femora blackish along posterior edge; median and hind femora largely darkened along basal half, fore tibiae yellow; meso and metatibiae darkened at apex; tarsi mostly yellow, more or less darkened towards apex. First protarsomere moderately broadened, as wide as apex of tibia. Apex of aedeagal median lobe (figure 4) acute, lateroventrally with row of white hairs, shaft thin and elongated, slightly careened along ventral surface, venter straight in lateral view. Female differs from male in: larger and stouter body (length 3.3 ± 0.1 mm); frons broader and, as result, eyes more separated; generally reduced yellow pattern; first protarsomeres significantly narrower than tibiae apically; rectal apparatus (figure 5 a,b) with two dorsal and one ventral sclerites; dorsal sclerites short and narrow, slightly wider than rectum, transverse connection across dorsal fold not perceptible, so sclerites essentially reduced to the apodemes only; ventral sclerite ribbon-like, evenly pigmented in the middle, with large and rounded apodemes at both ends, wider than rectum; dorsal and ventral sclerotizations of lateral fold present; spermatheca (figure 5 c) sickle-shaped, lightly pigmented, basal part not swollen; base reflexed, with gland and duct insertions well sclerotized, so that it seems bifurcated; duct not coiled, quite short, its insertion on bursa copulatrix not enlarged and only feebly and briefly pigmented. Diagnosis. Pachybrachis of medium-small size, characterized by elytral pattern, with marginal yellow stripe from anterior edge, to and around posterior margin, then along apical half of suture. This stripe interrupted only at humeral callus. Similar elytral marginal stripes are present in P. karamani Weise and P. fimbriolatus Suffrian, with which the new species forms a group, based on morphology. In P. karamani, the elytral yellow spots are generally smaller, and the irregularly distributed small spots that characterize P. holerorum are almost entirely missing. Pachybrachis fimbriolatus is distinguished from the new species by: less transverse and more minutely and densely punctured pronotum, reduced elytral yellow spotting, particularly, postmedian dot nearly always absent. The new species clearly differs from the all Pachybrachis species in the shape of the median lobe of aedeagus (figures 4 and 6). Distribution. The new species is endemic to Northern Apennines, Italy. The type locality is Emilia Romagna, Piacenza Prov., Passo del Pellizzone (also written “Pelizzone”) (44 ° 40 ' 48.84 "N 9 ° 44 ' 42.66 "E). Remarks. The biology of P. holerorum is poorly known. At Passo del Pellizzone it was collected in early June on Lotus herbaceus. This possible host was confirmed by the gut analysis of plant DNA from specimens at this locality. The preference of many species of the genus Pachybrachis for Fabaceae is well known (Jolivet and Hawkeswood 1995). Pachybrachis holerorum is restricted to the north and west Apennines and P. k a r a m a n i is on the Adriatic slopes of North and Central Apennines (Sassi 2006). Molecular and morphological evidence show that Pachybrachis holerorum and P. karamani are recently diverged sister species in adjacent allopatric ranges, suggesting vicariant origin for the two species. We take the opportunity here to designate a lectotype for P. karamani, to fix the identity of this species which is similar to P. holerorum. The syntypic series of P. k a r a m a n i consists of five specimens. We designate a male as lectotype, labelled as follows: Spalato (handwritten, white label) / Typus (printed, red label) / karamani Ws. (handwritten, white label) / Zool. Mus. Berlin (printed, yellow label) / Sintypus (printed, red label) / Pachybrachis karamani Weise, 1893 labelled by MNHUB 2012 (printed, red label). Pachybrachis karamani Weise, 1893 LECTOTYPUS Montagna & Sassi des. (Printed / red label). The remaining paralectotypes are labelled as follows: 2 ♂, 1 ♀: Spalato (handwritten, white label) / Typus (printed, red label) / Zool. Mus. Berlin (printed, yellow label) / Sintypus (printed, red label) / Pachybrachis karamani Weise, 1893 labelled by MNHUB 2012 (printed, red label).

Burlini 1968 (partly printed, white label) / Zool. Mus.

Pachybrachis karamani Weise, 1893 PARALECTOTYPUS Montagna & Sassi des. (Printed / red label). Concluding remarks In our study of these Pachybrachis populations, the combination of three different approaches (morphological features of the aedeagus, nucleotide distance values and a method delimiting species based on single-locus molecular data), has provided evidence for a new species and its sister taxon. The results contained in this work strongly confirm the urgent need to increase efforts to uncover the real biodiversity of the European fauna, in particular the Mediterranean region.

L'oro rosso della montagna
Per le sue modalità di produzione lo zafferano è la spezia più cara nel mondo e potrebbe rappresentare perciò un’interessante opportunità economica per piccole e medie aziende agricole multifunzionali delle aree di montagna. Per supportare questa produzione “di nicchia”, il Centro Interdipartimentale di Studi Applicati per la Gestione Sostenibile e la Difesa della Montagna ha attuato uno studio sulla qualità dello zafferano proveniente da coltivazioni delle zone alpine e offre una serie di servizi agli agricoltori che desiderano inziare la sua coltivazione
