The Industrial City: The Multi-Ethnic Frontier of the Twentieth Century
2004
Between 1890 and 1920, big American industrial cities represented the frontier for the more than 23 million immigrants from southern and eastern Europe, Asia, and Central America, as well as for the African-Americans from the South. The development of mass consumption industries and the interventionism of the federal government provided security at the workplace and a general improvement in living standards for blue collar workers. The local party machines, the industrial unions and the effects of the First World War fully integrated the new immigrants into politics. Mass culture and entertainment made Americanization easier and, together with organised crime, were a quick way of social asc…
Finding socially responsible portfolios close to conventional ones
2015
Abstract An increasing number of investors are interested in sustainable, responsible and impact investment (SRI). However, there is a concern about the possible financial sacrifice associated to this kind of investments. The design of Decision Support Systems assisting socially responsible investors in their investment decisions can contribute to stimulate SRI. In this paper the financial content of a portfolio selection model is discussed in order to justify that it can be integrated into a Decision Support System designed for investors interested in socially responsible investment but initially reluctant to pay a financial cost in exchange for increasing the social responsibility of thei…
Principi e metodi di intervento sociale nelle catastrofi: il contributo di Lena Dominelli
2016
Il servizio sociale in Italia si sta aprendo all’esperienza e alla riflessione per la costruzione di sapere professionale specifico nell’ambito dell’intervento in emergenza. In altre realtà nazionali ed internazionali, la consapevolezza del ruolo del servizio sociale nelle emergenze è già acquisita da tempo e questa competenza fa parte della formazione ordinaria o comunque di percorsi di specializzazione consolidati. Anche in Italia sta maturando questo cambiamento, pur se in modo ancora diseguale, secondo le specificità territoriali e la messa in rete ancora a macchia di leopardo delle iniziative. In questo impegno di costruzione di sapere, può offrire elementi ulteriori di riflessione il …
To B or Not to B: Comparative Genomics Suggests Arsenophonus as a Source of B Vitamins in Whiteflies
2018
Insect lineages feeding on nutritionally restricted diets such as phloem sap, xylem sap, or blood, were able to diversify by acquiring bacterial species that complement lacking nutrients. These bacteria, considered obligate/primary endosymbionts, share a long evolutionary history with their hosts. In some cases, however, these endosymbionts are not able to fulfill all of their host's nutritional requirements, driving the acquisition of additional symbiotic species. Phloem-feeding members of the insect family Aleyrodidae (whiteflies) established an obligate relationship with Candidatus Portiera aleyrodidarum, which provides its hots with essential amino acids and carotenoids. In addition, ma…

Assessment of Tourist Competitiveness by Analysing Destination Efficiency
2006
Recently the notion and the measurement of destination competitiveness have received increasing attention in the economics literature on tourism. The reason for this interest emerges from both the increasing economic importance of the tourist sector and the increasing competition on the tourist market as a consequence of the transition from mass tourism to a new age of tourism that calls for a tailor-made approach to the specific attitudes and needs of tourists. The central subject of this paper - inspired by the conceptual competitiveness model developed earlier by Crouch and Ritchie - concerns the efficiency of tourist site destinations. Using a dataset of 103 Italian regions for the year…
Exploring the sources of labour productivity growth and convergence in the Italian regions: some evidence from a production frontier approach
2009
This paper investigates labour productivity growth and regional convergence patterns in Italy over the time span 1982–2000. Starting from some evidence of spatial polarisation within Italian economy, the analysis aims at exploring the sources of this tendency. To this end, an approach based on data envelopment analysis (DEA) production frontiers is employed which allows to decompose labour productivity growth into efficiency change, technological progress and capital deepening, looking then at the relative contribution of each component to regional convergence. Moreover, some measures of human capital and public capital are used as augmentation factors of the conventional inputs. The study …
Centro e periferia nell'Etiopia imperiale: governare la frontiera nord-occidentale nel bassopiano di Gondar
2016
Il contributo analizza il processo di ristrutturazione dello Stato etiopico alla frontiera nordoccidentale tra il 1941 e il 1972, utilizzando come caso di studio un progetto di sviluppo agricolo finanziato da Banca Mondiale e Nazioni Unite nel distretto di Setit Humera. Metodologicamente, l’articolo si avvale di fonti primarie inedite raccolte negli archivi britannici, etiopici e della Banca Mondiale, così come di interviste orali e letteratura grigia La ri- visitazione delle strategie di governo del bassopiano non è un processo line- are, ma il risultato delle negoziazioni tra i diversi livelli di governo de jure ede facto che esercitano prerogative di sovranità lungo il confine. La dialet…
Consolidated challenge to social demand for resilient platforms : Lessons from Uber's global expansion
2017
Many in the industry see the ride-sharing company Uber as the significant advancement through information and communication technology (ICT) particularly of the digital service platform and sharing economy. Uber has been exploring the new frontier of the ICT-driven disruptive business model (IDBM) and succeeded in its global expansion to over 479 cities in more than 75 countries worldwide in June of 2016. Such rapid expansion provides constructive insights regarding the significance of IDBM, not only in transportation but also in almost all other business fields. While at the same time Uber's legal battles in some cities around the world raise a serious question regarding the rationale of I…
