Solving the Milk Addiction Paradox
Get PDFThe milk addiction paradox refers to an empirical finding in which commodities that are typically considered to be non addictive, such as milk, appear instead to be addictive. This result seems more likely when there is persistence in consumption and when using aggregate data, and it suggests that the AR(2) model typically used in the addiction literature is prone to produce spurious result in favor of rational addiction. Using both simulated and real data, we show that the milk addiction paradox disappears when estimating the data using an AR(1) linear specification that describes the saddle-path solution of the rational addiction model. The AR(1) specification is able to correctly discriminate between rational addiction and simple persistence in the data, to test for the main features of rational addiction, and to produce unbiased estimates of the short and long-run elasticity of demand. These results hold both with individual and aggregated data, and they suggest that, for testing rational addiction, the AR(1) model is a better empirical alternative than the canonical AR(2) model
Développement et mise à l’échelle des technologies de traitement et de réutilisation des eaux usées dans les pays d’Afrique méditerranéenne: le projet MADFORWATER
Get PDFL'objectif de MADFORWATER était de développer un ensemble de solutions technologiques et de gestion intégrées pour améliorer le traitement des eaux usées, leur réutilisation dans l’irrigation et l'efficacité de l'eau dans le secteur de l'agriculture en Tunisie, au Maroc et en Égypte. MADFORWATER a développé des technologies pour la production d'eau d’une qualité qui convient à l'irrigation à partir des canaux de drainage, des eaux usées municipales, agro-industrielles et industrielles et des technologies pour promouvoir l'efficacité et la réutilisation de l'eau dans le secteur de l’agriculture, initialement validées à l'échelle du laboratoire, et les a adaptées à trois bassins hydrologiques principaux dans les pays africains méditerranéens sélectionnées. Les technologies sélectionnées ont été adaptées et validées dans quatre installations/unités pilotes sur le terrain de traitement / réutilisation intégrés des eaux usées. Des stratégies intégrées de traitement et de réutilisation des eaux usées ciblées sur les bassins sélectionnés ont été élaborées, et des lignes directrices pour l'élaboration de stratégies de gestion intégrée de l'eau dans d'autres bassins des trois pays africains méditerranéens cibles ont été décrites, en tenant compte du changement climatique, de l'augmentation de la population et des scénarios de croissance économique. La pertinence sociale et technique des technologies développées et des instruments non technologiques par rapport au contexte local a été évaluée avec la participation des parties prenantes et des partenaires des pays africains méditerranéens. Des lignes directrices relatives aux instruments économiques et aux politiques pour une mise en œuvre efficace des solutions de gestion de l'eau proposées dans les pays africains méditerranéens cibles ont été élaborées. Le consortium MADFORWATER est composé de 17 partenaires, dont 5 d'Afrique du Nord et 1 de Chine

CLUB Working Papers in Linguistics Volume 4
Get PDFQuesto quarto volume della collana "CLUB Working Papers in Linguistics" raccoglie, in formato open access, una selezione dei contributi presentati durante l’anno accademico 2018/2019 nell’ambito delle attività del CLUB – Circolo Linguistico dell’Università di Bologna.
Le diverse discipline del linguaggio che sono rappresentate in questa miscellanea offrono al lettore uno sguardo d’insieme sulle ultime tendenze della ricerca in vari ambiti, tra cui la tipologia linguistica, la linguistica storica, la corpus linguistics, l’analisi del discorso e la linguistica clinica.
Come nelle precedenti edizioni, viene qui pubblicato anche un saggio tratto dalla tesi di laurea magistrale risultata vincitrice del premio CLUB Day "Una tesi in linguistica": quest’anno, il lavoro scelto è di Dennis Fucci.
I sette articoli, redatti in italiano, inglese o francese, sono dunque (in ordine alfabetico) di Giorgio Francesco Arcodia, Alessandra Barotto, Claudia Roberta Combei, Claire Doquet, Chiara Fedriani, Dennis Fucci, Gloria Gagliardi e Simone Mattiola.
Come di prassi, tutti i contributi sono stati sottoposti a un processo di revisione anonima da parte di due reviewer esperti, scelti all’interno o all’esterno del comitato scientifico della collana
Access and Labour Market Outcomes of Internships During Higher Education in Italy and the United Kingdom
Get PDFThis paper explores the accessibility to internships and undertaken during higher education in Italy and the UK, and how these internships affect graduates’ transitions to work in the UK and Italy, countries in which the incidence of internships during HE study used to be lower compared to other European countries, but has increased over time. Results show that internships both in the UK and Italy have a positive effect on being employed after graduation, and in the UK they also have a positive effect on wages. Comparing graduates’ early career outcomes in two different institutional contexts also highlights the importance of having a clear definition of internships to distinguish them from other types of work experience within and beyond national and institutional boundaries
Within-between decomposition of the Gini index: a novel proposal
Get PDFThe socioeconomic impact of spatial concentration has been receiving an increasing attention during the last two decades. Consequently, the necessity of effective measures of this phenomenon has increased too. This paper considers a population partitioned by subgroups and develops a decomposition of the Gini index in two components, which measure the within and the between group inequality and are also particularly effective to quantify spatial concentration. Indeed, they possess a crucial property which overcomes important issues that may arise using any Gini index decomposition in the spatial context, following a recent approach. In addition, the availability of an only-two highly informative components decomposition provides in numerous applications and several frameworks further significant advantages in the determination of the contributions to global inequality of the intra and the inter groups differences. The ability of the components to capture these phenomena is supported by a parametric bootstrap procedure. This highlights extremely high correlations between the components and two axiomatically derived benchmarks. The presentation of a case study concerning the income distribution in the Italian provinces concludes the works, the informativeness and the interpretative advantages of the proposed decomposition appear evidently

Logistica delle migrazioni
Get PDFLa logistica si è recentemente imposta come una prospettiva privilegiata per la comprensione del mondo contemporaneo a partire dall’interazione tra mobilità multiple – di persone, merci, capitali, informazioni. Tuttavia, questa prospettiva rischia di risolvere nel presente dinamiche che sono ricorse storicamente in modali-tà diverse, non lineari e reversibili. I contributi di questo volume si pongono l’obiettivo di mettere in evidenza le specificità storiche e geografiche dei processi logistici. Essi contribuiscono alla definizione di una “logistica delle migrazioni” a partire da casi di studio specifici, proponendo al tempo stesso alcuni elementi utili a problematizzare continuità e rotture storiche all’interno di un confronto tra scien-ze storiche e scienze politico-sociali
Trasmissione
Get PDFTrasmissione è una mostra digitale organizzata dagli studenti AMaC e ABABO. Questo catalogo presenta le otto opere realizzate dagli undici artisti dell’Accademia di Belle Arti di Bologna, selezionati dai giovani curatori del corso di laurea magistrale Arts, Museology and Curatorship. L’introduzione, seguita dal saggio a cura del direttore scientifico Anna Rosellini, inaugura il quesito su cui la mostra si è concentrata: “cosa trasmetteremo alle prossime generazioni?”. La presentazione delle singole opere culmina con un’opera collettiva, suggerita dalla collaborazione con l’associazione universitaria Culturit, che sintetizza gli sforzi individuali degli artisti nel medium espositivo che accomuna tutte le creazioni: Internet. Il catalogo si conclude infine con una sintesi delle riflessioni condotte dagli artisti e dai curatori al termine del progetto
