Sept. 2000. Paratypes, 1 male (10.4 x 7.8), 1 young female (6.5 x 8.1), MZUF-4930. Description of holotype. Carapace transversely suboval in outline, about 1.3 times as wide as long, with greatly expanded branchial regions concealing ambulatory legs; dorsal surface smooth to the naked eye, margins lamellate, upcurved, closely and minutely granular, prominent conical protuberance medially (Fig. 2A). Front narrow, produced, upturned; margin slightly concave. Anterolateral margin rounded, continuous with posterior margins; posterior margin slightly wider than frontal margin, sinuous, bearing two flattened submedian lobes. Rounded median ridge running from front to conical gastrocardiac protuberance, culminating in cluster of flattened granules. Intestinal region with low protuberance medially. Epibranchial ridge rounded, inconspicuous, running obliquely from gastrocardiac protuberance to posterolateral margin. Ocular peduncle very short. Antennule folded into oblique fossa. Infraorbital margin with orbital hiatus closed by basal segment of antenna, distally with granulate pit. Anterolateral margin of buccal region raised, granulate, running parallel to anterolateral margin distally, notched on anterior margin. Third maxillipeds with margins of exopod and endopod closely granulate; endopod merus nearly as long as ischium along mesial margin, distally granulate; exopod slightly arcuate. Surfaces of pterygostomial, sub-hepatic and sub-branchial regions smooth, sparsely punctate. Cheliped slender. Merus trigonal, margins prominently granulate. Carpus globular, granulate; upper margin carinate. Palm laterally compressed, elongate, margins carinate, boldly granular; inner surface bearing a curving row of pearliform granules extending to dactylar articulation. Fingers short, bearing rows of granules extending to tips, tips crossing when closed. Ambulatory legs granulate, laterally compressed, similar in shape, gradually decreasing in length from first to fourth, hidden by extended branchial regions of carapace in dorsal view when retracted; meri unicarinate, carpi, propodi bicarinate on upper margins, meri bicarinate, propodi unicarinate on lower margins. Pleon with proximal two somites narrow, yoke-shaped; distal somites fused, bearing large triangular denticle subterminally; telson subtriangular (Fig. 2B). G1 (Fig. 4A,B) stocky, sinuous, distally setose, tip claw like. G2 short, filiform, tip laciniate (Fig. 4C). Colour (in life). Carapace, legs, bone colored; brown stripe running along median ridge from front to conic gastrocardiac protuberance, 3 brown dots on posterior margin (fide G. Innocenti). Etymology. The specific epithet, halimedophila, alludes to the carapace shape of the new species, which convincingly resembles a segment of dead coralline algae (Halimeda spp.). Used as an adjective. Distribution. Known from specimens collected from the type locality – Watamu, Kenya. Remarks. Leucisca halimedophila n. sp. resembles L. rubifera (Müller, l887) in the general outline of the carapace and chelipeds, and in possessing triangular denticle subterminally on male abdomen, but the present species is distinguished by a broader carapace, more prominent conic gastrocardiac protuberance, and less prominent intestinal protuberance than L. rubifera (Müller l887: tab. 4, fig. 4, 4a,b; Tirmizi & Kazmi 1979: fig. 3a,b; Naderloo 2017: fig. 14.20). The posterior margin is produced, bearing two flattened submedian lobes, rather than smoothly convex as in L. rubifera. The granulation on margins of the carapace, thoracic sternites, 3rd maxillipeds are much finer than in L. rubifera. Finally, G1 is stocky, sinuous, distally setose, and with a claw-like distal tip, rather than styliform as in L. rubifera (Tirmizi & Kazmi 1979: fig. 3c; Naderloo 2017: fig. 14.21c).Published as part of Galil, Bella S. & Innocenti, Gianna, 2019, Rare and new East African leucosiid crabs, pp. 139-145 in Zootaxa 4555 (1) on pages 140-142, DOI: 10.11646/zootaxa.4555.1.12, http://zenodo.org/record/262407

A Conceptual Framework of Age Diversity Climate
No full textThe age diversity climate construct is gaining greater attention in the organisational literature due to the demographic changes in the workplace. While the few existing studies on age diversity climate (ADC) are rather encouraging, this construct is still at an early stage of conceptual and operational development. This chapter helps to advance this field of research by analysing the conceptual issues stemming from the theoretical definition and empirical measurement of the ADC construct. We first review and compare ADC with other age-focused climate concepts, highlighting overlapping and diverging factors regarding their conceptual framework and operationalization. Subsequently, we consider several open issues related to the operationalization of ADC, including the level of analysis, the choice of referent, and the dimensions of analysis. We conclude the chapter by outlining possibilities for future research on ADC

Rethinking authenticity in digital art preservation
No full textIn this paper I am discussing the repositioning of traditional
conservation concepts of historicity, authenticity and versioning
in relation to born digital artworks, upon findings from my
research on preservation of computer-based artifacts. Challenges
for digital art preservation and previous work in this area are
described, followed by an analysis of digital art as a process of
components interaction, as performance and in terms of
instantiations. The concept of dynamic authenticity is proposed,
and it is argued that our approach to digital artworks preservation
should be variable and digital object responsive, with a level of
variability tolerance to match digital art intrinsic variability and
dynamic authenticity

The diameter of cortical axons depends both on the area of origin and target
No full textIn primates, different cortical areas send axons of different diameters into comparable tracts, notably the corpus callosum (Tomasi S, Caminiti R, Innocenti GM. 2012. Areal differences in diameter and length of corticofugal projections. Cereb Cortex. 22:1463-1472). We now explored if an area also sends axons of different diameters to different targets. We find that the parietal area PEc sends thicker axons to area 4 and 6, and thinner ones to the cingulate region (area 24). Areas 4 and 9, each sends axons of different diameters to the nucleus caudatus, to different levels of the internal capsule, and to the thalamus. The internal capsule receives the thickest axon, followed by thalamus and nucleus caudatus. The 2 areas (4 and 9) differ in the diameter and length of axons to corresponding targets. We calculated how diameter determines conduction velocity of the axons and together with pathway length determines transmission delays between different brain sites. We propose that projections from and within the cerebral cortex consist of a complex system of lines of communication with different geometrical and time computing properties. © The Author 2013
Castelli di acciaio. Il sistema tubo-giunto di Ferdinando Innocenti
No full textIn August 1935, an unconventional scaffold was used in the construction of a cast-in place, reinforced concrete arch bridge spanning 50 m across the Orba river. That was the first steel tube scaffold ever built in Italy. It had been designed and constructed by Fratelli Innocenti.
The company owner was Ferdinando Innocenti, who in 1934 had invented a revolutionary metal tube uniting device, which is still among the best products manufactured in Italy. The device featured a quickly assembled, portable and reusable system consisting of a clamping bolt with a T-shape head and a hinge. The novel Innocenti system was more cost-effective than traditional timber framing. For this reason, it was to be used, in the Fifties, in the construction of some major bridges connecting the Autostrada del Sole, and later in the realization of various masterpieces of Italian engineering in the boom years.
In the Thirties, the Innocenti system was applied to reinforced concrete construction projects, to set up imposing, temporary works to suit the needs for Fascist propaganda, and also for military use.
In post-war years, following the establishment of a new company called Ponteggi Tubolari Dalmine Innocenti, the pipe joint system was used in the construction of awe-inspiring, dismountable and portable steel tube scaffolds designed to support viaducts connecting the new motorways.
In 1958, the transfer of the scaffold to be applied to the construction of the twin arch bridge across the Aglio river along the Autostrada del Sole was a pioneering technology performance. RAI, Italy’s public broadcasting company, covered the entire event live, and a documentary film would be produced, which represented Italy at the 1960 Locarno Film Festival.
During the same months, even Pier Luigi Nervi used the pipe joint system to combine the precast and cast-in place components of his Palasport domes.
On October 24, 1959, one of the high towers Ponteggi had erected to support the prestressed girders of the Lora bridge collapsed. As a result, the popularity of the steel castle suddenly dimmed. In order to investigate on the causes of the structural failure, Ponteggi requested ISMES in Bergamo to carry out a series of model-based tests. Between 1961 and 1962, the pipe joint system was used in the construction of a bridge spanning 235 m across the Fiumarella river in Catanzaro and of other viaducts connecting the Autostrada del Sole in the Florence-Rome. However, no word was spread about those works.
In 1965, the Innocenti system was used in the last daring work carried out by Ponteggi Tubolari Dalmine Innocenti in Europe: the construction of the 275 m span arch bridge across the Breguenzer River in Austria.
That anticipated also the end of the cast-in place, reinforced concrete arch era and the dissolution of the distinguishing features of the Italian construction site that had been represented by Ferdinando Innocenti’s creatio
