Young Adults Living Apart and Together (LAT) with Parents: A Three-level Analysis of the Italian Case
Full text linkBillari F. C., Rosina A., Ranaldi R. and Romano M. C. Young adults living apart and together (LAT) with parents: a three-level analysis of the Italian case, Regional Studies. This paper introduces the notion of living apart together (LAT) with one's parents as a status in the transition to adulthood. LAT with parents is defined as the situation in which young adults who reside with their parents spend a significant amount of that time living outside the parental household. Young adults who LAT with parents are described and the determinants of LAT are analysed with reference to Italy. The relevance of this phenomenon is documented for Italy, a country with one of the highest share of young adults cohabiting with parents and with fundamental subnational differences both on higher education provision and in the labour market situation. Official survey and census data are analysed and a multi-level statistical model is used to analyse the determinants of the LAT choice, with individuals, households and municipalities as levels.

Les jeunes qui vivent a la fois separement et a la maison: une analyse a trois niveaux de la situation en Italie, Regional Studies. Cet article cherche a presenter la notion de LAT (living apart together - autrement dit, vivre a la fois separement et chez ses parents) comme position sociale au passage a l'age adulte. On definit LAT chez ses parents comme la situation ou les jeunes qui habitent chez leurs parents passent une proportion non-negligeable de leur temps en dehors de la maison de leurs parents. On decrit les jeunes qui vivent chez leurs parents et en analyse les determinants pour ce qui est de l'Italie. On decrit l'importance de ce phenomene pour l'Italie, un pays qui comprend une proportion de jeunes adultes qui habitent chez leurs parents parmi les plus elevees et dont les differences infranationales quant aux services d'enseignement superieur et a la situation sur le marche du travail sont fondamentales. On analyse des donnees officielles provenant des enquetes et des recensements de la population et emploie un modele statistique a plusieurs niveaux afin d'analyser les determinants du choix de LAT a partir des individus, des menages et des municipalites.

Getrenntes Zusammenleben zwischen jungen Erwachsenen und ihren Eltern: eine dreischichtige Analyse des Falls von Italien, Regional Studies. In diesem Artikel fuhren wir den Begriff des getrennten Zusammenlebens mit den Eltern als Zustand wahrend des Ubergangs in das Erwachsenenleben ein. Wir definieren getrenntes Zusammenleben mit den Eltern als die Situation, in der junge Erwachsene, die bei ihren Eltern wohnen, einen erheblichen Teil ihrer Zeit ausserhalb des Elternhauses verbringen. Wir beschreiben junge Erwachsene, die mit ihren Eltern getrennt zusammenleben, und analysieren die Determinanten des getrennten Zusammenlebens anhand des Falls von Italien. Wir dokumentieren die Relevanz dieses Phanomens fur Italien, ein Land mit einem der hochsten Anteile an noch im Elternhaus wohnenden jungen Erwachsenen und mit grundlegenden subnationalen Unterschieden hinsichtlich des Angebots an hoherer Bildung und der Situation auf dem Arbeitsmarkt. Wir analysieren offizielle Erhebungs- und Volkszahlungsdaten und ermitteln mit Hilfe eines mehrschichtigen Statistikmodells die Determinanten fur die Entscheidung zum getrennten Zusammenleben auf den Ebenen der Einzelpersonen, Haushalte und Gemeinden.

Carbon capture and storage from energy and industrial emission sources: A Europe-wide supply chain optimisation
Full text linkPower, steel, cement and refining sectors are currently responsible for the largest shares of carbon dioxide emissions from stationary sources. Carbon capture and storage is envisioned as a key player for decarbonising the power and industry sectors. To achieve a significant penetration of carbon capture and storage technologies, supply chain optimisation has emerged as a crucial research task for designing such complex systems. A Europe-wide carbon capture and storage supply chain is here optimised via a mixed integer linear programming framework. The most significant carbon dioxide emitters (242 power plants, 25 steel mills, 111 cement plants and 59 refineries) are identified on exact geographic coordinates and included as candidates for capture. Capture plants are thoroughly represented in techno-economic terms, considering scale effects and different technological options. Transport and sequestration stages are implemented for either onshore or offshore operation. Different case studies are taken into account to assess carbon capture and storage policies and results determine optimal configurations in terms of costs, scale effects, technology options and network complexity. The minimum CO2 avoidance cost is 52 €/t, which increases by 9% if power plants are excluded from carbon sources. If offshore storage is preferred to onshore, cost raises by about 40%

No full text“Potential carbon efficiency” as a new index to track the performance of biofuels production processes
No full textIn a carbon constrained economy which targets a massive reduction of the CO2 emissions, biogenic carbon is bound to be a scarce resource with high economic value. In such scenario, the carbon efficiency may become the key performance index to represent the revenues of the biomass-to-X conversion plants. In this work, the potential carbon efficiency (PCE) indicator is defined to quantify the achievable carbon efficiency (i.e. the amount of carbon contained in the final product with respect to the available input carbon), of a stream or of a process unit. Compared to the conventional carbon efficiency (CE), that is affected only by the separation/addition of carbon-containing species, the PCE allows quantifying the potential variation of the achievable carbon efficiency in process units where no carbon separation occurs, but where a limiting element is added (e.g. hydrogen through steam addition) or oxygen content is increased (e.g. oxygen injection in a reformer). The difference between the CE and the PCE along a biomass conversion process is typically due to the excess of oxygen atoms in the syngas, which is removed as CO2 in the syngas conditioning unit. Therefore, the difference between CE and PCE shows the potential gain in carbon efficiency that can be obtained by the addition of H2 from an electrolysis process. In this paper, the PCE and the CE have been calculated along the process units of different biomass-to-X plants. The selected case studies allow comparing different gasification technologies (direct gasification, indirect gasification and sorption enhanced gasification) in plants for the production of methanol and synthetic natural gas, showing how CE and PCE are influenced by process units such as the gasification technology, syngas reforming, syngas conditioning and hydrogen addition
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
