Tracking sectoral progress in the deep decarbonisation of energy systems in Europe
No full textDecarbonisation of energy systems requires deep structural change. The purpose of this research was to analyse the rates of change taking place in the energy systems of the European Union (EU), in the light of the EU's climate change mitigation objectives. Trends on indicators such as energy intensity and carbon intensity of energy were compared with decadal benchmarks derived from deep decarbonisation scenarios for the electricity, residential, transport, and industry sectors. The methodology applied provides a useful and informative approach to tracking decarbonisation of energy systems. The results show that the EU has made significant progress in decarbonising its energy systems. On a number of indicators assessed the results show that a significant acceleration from historical levels is required in order to reach the rates of change seen on the future benchmarks for deep decarbonisation. The methodology applied provides an example of how the research community and international organisations could complement the transparency mechanism developed by the Paris Agreement on climate change, to improve understanding of progress toward low-carbon energy systems. © 2017 Elsevier Lt
Le aree agricole
No full textL’Isola dell’Asinara, nella grande diversità e varietà dei suoi ambienti, presenta alcune porzioni di territorio che hanno avuto un significativo interesse agrario. Le superfici utilizzate sono rappresentate all’incirca dal 5% della superficie totale ma, di fatto, costituiscono tutte le porzioni di territorio che potevano avere una possibilità di utilizzo per le coltivazioni. Inoltre il pascolamento, sia dei selvatici che dei domestici, ha da sempre interessato l’intera superficie dell’isola, comportando pesanti effetti negativi sulla vegetazione naturale. Le fasi storiche che si sono succedute, in particolare quelle che hanno riguardato l’ultimo trentennio dell’attività carceraria, hanno fortemente caratterizzato le linee nelle trasformazioni agrarie e le strategie delle scelte nei sistemi agro zootecnici; è principalmente a questo periodo che si dovrà fare riferimento per le scelte gestionali del Parco per le aree agricole
Lo statuto del segreto nell’Amadas et Ydoine
No full textNello Statuto del segreto nell’Amadas et Ydoine viene evidenziata l’elaborazione di una nuova etica comportamentale, quella assunta appunto dal ‘segreto’ inteso come ‘secretazione’, formale e non sostanziale, che appare come l’unica possibilità di comporre l’antinomia altrimenti insuperabile tra dimensione emotivo-soggettiva e mondo delle regole costituite. Nell’Amadas et Ydoine si assiste infatti all’evoluzione dello statuto del segreto che, se appare al principio del romanzo come emblema di quell’etica della rinuncia, di ascendenza mistico-cortese, che condurrà il protagonista maschile alla follia, diverrà invece, alla fine del percorso narrativo, lo spazio autonomo che permetterà la conciliazione tra desideri individuali e norme sociali
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
Atteggiamenti linguistici nella Sardegna medievale tra diatopia e diastratia: il caso della Metatesi Locale
No full textThe paper analyses a specific pattern of the metathesis of the rhotic
consonant /r/ in the diachrony of Sardinian, called Metatesi Locale
(ML). Contrary to the main pattern of the Sardinian metathesis, usually
associated to rustic varieties and resulting in an initial branching onset
derived from a mediai RT or TR cluster, ML creates mediai RT clusters
from a branching onset. Moreover, data from the Sardinian ancient texts
(condaghes) suggest that the two conflicting metathetic patterns are
coèval, and the synchronic diatopic distribution of ML reveals that it is
limited to the transitional area between Northern dialects (not affected
by metathesis) and Southern dialects (pervasively affected by the phenomenon).
On the basis of this scenario, the author proposes that ML
might be interpreted as a hypercorrection emerged by the willing of
the ancient writers to avoid those forms deemed basilectal, thus trying
to produce a diastratically and diaphasically high variety. The proposal
is in line with the hypothesis claiming that a portion of the synchronic
diatopic differences of the Sardinian dialectal group represented diastratic
and diaphasic varieties in the past
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
