Full text linkThe contribution deals with the relationship between product design and innovation leveraging on the added value of the design to the product.
The concept of innovation is here understood not only to produce tout court a new artifact, but also to implement strategies aimed at enhancing the skills and processes already present in the company, which, by means of simple changes in sense or applications can make products unexpectedly innovative. In our region, Apulia, we have a system of firms among the most numerous in southern Italy but, at the same time, with low awareness of the value coming from the support of the design, which can incisively improve strategies and products. Innovation can be realized through recognition of own potentials and a different use of their own competence and technologies already in use at the firm within their territory
The interplay of erosion, instability processes and cultural heritage at San Nicola Island (Tremiti Archipelago, Southern Italy)
No full textThe cliffs of the Tremiti Islands, which are located in the Adriatic Sea in the north of the Apulian coastline (Southern Italy), are affected by severe instability processes. From the geological point of view, the Tremiti Islands are made of a sequence of bioclastic limestone, dolomitic limestone, calcilutite and calcarenite, with the age ranging from Paleocene to Middle Pliocene. These rocks are covered by a calcareous crust and loess deposits (Upper Pleistocene- Holocene). The structural set up of the major islands of the Tremiti (San Nicola and San Domino) is controlled by predominant NE-SW and E-W fault systems, which mark the coasdines of the islands. Along the cliffs, severe erosive processes are produced by different factors, as the climate and sea actions, and the effects of these processes are worsened by the seismic activity which affects the evolution of the cliff stability with time. Deeper instability processes are also observed at the Island of San Nicola as an effect of the presence of weak and low-cemented rock formations that are composed of dolomitic calcarenites, at the top of the island, and calcilutites. These processes are mainly represented by block topplings, slidings, rockfalls and roto-translative mass movements in some limited areas. These processes mainly threaten the cultural heritage buildings located on the island, as the Santa Maria Abbey, which have already suffered significant damages in the past. This study has represented the background for the engineering design of both the restoration works of the monumental area and the stabilization works of the cliffs below
Diagnostic usefulness of BAEPs. A clinical case
No full textWe report the clinical case of a patient operated for a right extracerebral haematoma. In the immediate post-operative period, although no clinical signs were present, a BAEP examination (showing the lack of the V) warned of a pathological condition which was ascertained by CT. A second haematoma was observed, contralateral to the first, and immediately removed. In this case, therapy was based on the neuroelectrophysiological findings
Holocene episodic subsidence and steady tectonic motion at the ancient Sybaris (Calabria, southern Italy)
No full text“Punishment for the Sinner”: Holocene episodic subsidence and steady tectonic motion at ancient Sybaris (Calabria, southern Italy).
No full textAlthough the Calabria region in southern Italy experienced Quaternary uplift, intense Holocene subsidence
is documented at ancient Sybaris, one of the most powerful among the Greek colonies collectively known
as Magna Greacia. Sybaris flourished along the Ionian Sea coast of north-eastern Calabria since 2.7 ka BP
and until the end of the Roman empire, when it went progressively concealed below the ground. Study of
the Latest PleistoceneeHolocene evolution of this area involved analysis of the relative sea-level history for
individual borehole logs, based on re-calibration of published ages and stipulation of nominal sea-level
positions related to each marker. For investigation of the short-term evolution, a novel compilation of
geological and archaeological sea-level markers was supported by new radiometric ages. Appraisal of the
position of dated markers, when compared to a sea-level curve built on purpose for this coast using an
updated glacio-hydro-isostatic model, indicates a locally intense difference in vertical motion between
boreholes located away from, or close to, the ancient town. Specifically, whereas data from the basement of
the archaeological layers document large subsidence, more distant sites behaved differently. A site w2 km
to the NW of the settlement was apparently stable throughout the Holocene, and a site w6 km to the SE
experienced uplift at w1.5mm/y since 0.6 ka BP. In addition, analysis reveals temporal changes in subsidence
pattern in the archaeological area. Large (5e6 mm/y) Early Holocene subsidence at Sybaris slowed to
w1.5mm/y during the middle part of the Holocene. The slowing-down trend continued during and after
historical occupation at w0.8 mm/y, a value similar to the long-term (35e40 ka BP) rate established from
the deepest borehole samples. These data are interpreted as suggesting that sediment compaction affected
the basement of Sybaris during the Early Holocene, and progressively ceased during historical times, when
a tectonic signal prevailed. During historical time, the spatial difference in vertical motion is chiefly
attributed to differential growth of nearby folds documented by morpho-tectonic studies on-land and
seismic profiles analysis in the offshore of Sybaris. Whereas location above a syncline caused tectonic
subsidence at Sybaris, the regions to the north and south record stability or uplift that reflects transition to
growing anticlines. In the short term (1e10 ka scale), these local tectonic processes prevail over the
regional uplift pattern, which is expressed at the 100 ka scale or over

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
