Una “triangolazione” informale: Morlotti, Testori, Arcangeli
No full textIl saggio ricostruisce i rapporti di collaborazione e intenso confronto tra Ennio Morlotti, Giovanni
Testori e Francesco Arcangelo nei primi anni del secondo dopoguerra, quando la pittura “informale”
comincia a farsi spazio anche in Italia. L'analisi dell'esperienza artistica di Morlotti attraverso le
interpretazioni critiche di Arcangeli e Testori risulta fondamentale per delineare il dibattito tra
realismo e astrattismo sulla possibilità di rappresentazione della figura umana che sfocia – passando
attraverso la scomposizione cubista di Picasso e le dense pennellate di Cézanne – nell'ampia gamma
dell'arte “informel” italiana. In particolare i due critici d'arte hanno sostenuto, in prospettive diverse,
la validità la corrente del “naturalismo informale”, caratterizzata da un rinnovato rapporto con la
natura a partire da una matrice “romantica” e sentimentale. I loro studi sull'opera di Morlotti e degli
“ultimi naturalisti” forniscono un punto di partenza fondamentale per analizzare gli sviluppi
dell'estetica “informel” sia in campo artistico che letterario. Si possono rintracciare notevoli
corrispondenze tra le figure “informali” dipinte da Morlotti negli anni '50 e i corpi dei personaggi
descritti da Testori nel ciclo “I segreti di Milano” (1954-1962). Tali rapporti sono avvalorati anche
dalla triangolazione della corrispondenza tra il critico d'arte bolognese e i due autori lombardi,
conservata nell'archivio “Arcangeli” presso la Biblioteca comunale dell'Archiginnasio di Bologna
Le conclusioni dell’Avvocato Generale sul caso HaqbinC-233/18: la revoca delle condizioni materiali diaccoglienza del minore straniero non accompagnato èuna sanzione legittima o una violazione irragionevoledei diritti del minore?
Full text linkPrendendo le mosse dalla presentazione delle conclusioni dell’Avvocato generale Manuel Campos Sànchez-Bordona dinanzi alla Corte di Giustizia dell’Unione Europea del 6 giugno 2019, relative alla causa Zubair Haqbin contro Federal Agentschap voor de opvang van asielzoekers, questo contributo si propone di analizzare in che modo possa essere legittimamente applicato l’articolo 20, paragrafo 4, della Direttiva 2013/33/UE, in merito alla previsione di sanzioni applicabili al minore straniero non accompagnato qualora egli tenga un comportamento scorretto e/o violento all’interno del centro di accoglienza presso il quale è ospitato. La questione si presenta delicata dal momento in cui la sanzione si è declinata nel caso di specie in una totale privazione del minore delle condizioni materiali di accoglienza, la quale potrebbe rappresentare una violazione del “tenore di vita dignitoso” che gli Stati membri sono obbligati a garantire in ogni caso al richiedente asilo, a maggior ragione se egli, in quanto minore non accompagnato, è persona vulnerabile e quindi destinatario di maggiori garanzie non solo in forza del diritto dell’Unione Europea ma anche e soprattutto del diritto internazionale. Alla luce delle numerose garanzie previste dalla normativa vigente in tema di tutela del minore non accompagnato, le quali si riflettono anche in recenti pronunce della Corte EDU e del Comitato Europeo sui diritti sociali, le sanzioni che gli Stati membri hanno diritto di applicare per tutelare la sicurezza e l’ordine pubblico all’interno e fuori dai centri di accoglienza devono necessariamente raccordarsi con l’effetto utile delle stesse nonché con la tutela della dignità umana e la protezione del minore, anche se quest’ultimo è reo di comportamenti scorretti, violenti o comunque violativi delle regole del centro di accoglienza ospitante.Building on the opinion of the Advocate General Manuel Campos Sànchez-Bordona delivered on 6 June 2019, relating to the Zubair Haqbin case against Federal Agentschap voor de opvang van asielzoekers, this paper aims to analyze how article 20, paragraph 4 of Directive 2013/33/EU can be legitimately applied, with regard to the provision of sanctions applicable to unaccompanied foreign child if he behaves incorrectly and / or violently within the reception center where he is hosted. The issue is peculiar because of the sanction, in this particular case, was declined in a total deprivation of the material reception conditions, which could represent a violation of the “dignified standard of living” that the Member States are obliged to guarantee in any case to the asylum seeker, all the more so if he, as an unaccompanied minor, is a vulnerable person and therefore he had right to greater guarantees, not only by virtue of European Union Law but also and above all of International Law. About of the many guarantees provided for by current legislation on the protection of unaccompanied minors, which are also reflected in recent judgements by the EDU Court and the European Committee on Social Rights, the sanctions that Member States have the right to apply to protect the security and public order inside and outside the reception centers must necessarily be linked to the “useful effect” as well as to the protection of human dignity and the protection of the child, even if the child is guilty of incorrect, violent behavior or he had violated the rules of the host reception center

No full textThe dynamics between price and demand of myopic and strategic consumers in the air transport industry
Full text linkThis thesis sheds light on the relationship between dynamic pricing strategies and consumer demand in the air transport industry. The work is structured around three main research questions, which explore revenue management implementation and the relative influence on consumers’ purchasing behavior. The first research question extends the literature on airline pricing strategies by investigating the presence of quantity price discrimination of a leading European low-cost carrier, finding evidence of a two-part tariff pricing structure in offered fares (i.e., airfares are composed by a fixed fee per reservation and a variable component of price). Interestingly, the application of this kind of strategy is not linear in volume and it generates quantity discounts. Quantity discounts do not substitute the typical pricing discrimination strategies implemented by airlines, rather they are an additional way in which airlines price discriminate consumers. Second, to have an overview of the effectiveness of implementing price discrimination strategies, passengers’ price elasticity of demand is investigated. Outcomes suggest that price elasticity of European low-cost passengers greatly varies across different dimensions (i.e., seasonality, booking and flight characteristics, and served markets). Specifically, price elasticity is higher for reservations made more days in advance, as well as for bookings and departures occurring at weekends. Moreover, flights taking off during lunchtime and in the summer period are characterized by more sensitive passengers with respect to other daily timings and during springtime. As a third step, since price variations are the main outcome of revenue management, their impact is quantified by considering an advanced measure of price volatility, which takes into account past and more recent price changes, as well as the predictability of fare changes over time. Empirical analyses reveal that with higher degrees of price volatility (above and beyond the predicted price trajectory), demand decreases coupled with a significant decrease in price elasticity. Intuitively, price volatility induces lower demand elasticity, whereby consumers may end up paying more, but possibly reducing the overall demand (given the higher price). This insight suggests the need to incorporate the effects of price volatility on consumers’ demand into the classical revenue management model (Expected Marginal Seat Revenue), demonstrating its potential implementation benefit, while capturing the potential harm caused by the presence of strategic consumers. Overall, this thesis gives new explanations on consumers’ behaviour and timing of their purchases: i) consumers’ knowledge of price discrimination strategies helps in their timing decision in order to pay a lower price; ii) acknowledging that only in markets where consumers are price sensitive it is beneficial to implement price drops, price elasticity estimates on different dimensions lead passengers to more easily identify the possibility that airlines plan price variations; and iii) consumers may take advantage of price fluctuations and wait for downward price adjustments

To Jump or not to Jump? This is the Queue
No full textCongestion at airports leads to flight delays and, therefore, to costly implications for airlines. As departure queues for takeoff at airports, we observe deviations from first-come-first-serve, which can be perceived as unfair. In this work, we assess whether such deviations exhibit any systematic bias, by studying position shifting at takeoff queues at the 30 largest US airports.
Our empirical analysis reveals (i) that such deviations can be quite significant with 19\% of the flights in our data exhibiting a shift of five or more positions, and (ii) that an airline's market share at an airport (in terms of number of operated flights) plays a major role in how flights of these airlines are treated. In particular, flights operated by an airline with a larger market share are more likely to move up the queue and the number of spots associated with such a jump increases with the airline's market share.
Robustness analyses lend further support to these results and, in particular, Control Function Analysis allow us to decouple the benefits dominant carriers enjoy at airports into their geographical component (i.e., their terminal location with respect to the runway proxied by the shortest taxi-out time) and their preferential treatment in the departure queue.
These result have important implications for fairness and its distribution across airlines and their respective flights
Integrating price volatility into revenue management: exploring the tradeoff between price fluctuations and strategic consumers
No full textPrice fluctuations largely influence consumers’ purchasing behavior in two opposite directions: they affect price sensitivity and the acceptable price ranges, while favoring consumers to exhibit strategic behavior by waiting for prices to come back down. Firms selling revenue-managed goods can exploit this tradeoff to efficiently implement revenue management practices. We illustrate how to incorporate price volatility into the classic Expected Marginal Seat Revenue model. Our results reveal that, in certain market conditions, such integration could result in a significant increase in revenue. We further provide guidance to support pricing decisions when faced with the price sensitivity—strategic consumers tradeoff
