Ligation Tunes Protein Reactivity in an Ancient Haemoglobin: Kinetic Evidence for an Allosteric Mechanism in Methanosarcina acetivorans Protoglobin

2012

Abstract: Protoglobin from Methanosarcina acetivorans (MaPgb) is a dimeric globin with peculiar structural properties such as a completely buried haem and two orthogonal tunnels connecting the distal cavity to the solvent. CO binding to and dissociation from MaPgb occur through a biphasic kinetics. We show that the heterogenous kinetics arises from binding to (and dissociation from) two tertiary conformations in ligation-dependent equilibrium. Ligation favours the species with high binding rate (and low dissociation rate). The equilibrium is shifted towards the species with low binding (and high dissociation) rates for the unliganded molecules. A quantitative model is proposed to describe t…

Femminilizzazione dei flussi migratori, vulnerabilità di genere e diritto alla salute. Il caso degli accessi ai servizi sanitari dell’ARNAS Civico di…

2021

Salute, genere e migrazione sono temi di ricerca che difficilmente si armonizzano tra loro. L'articolo si concentra sul tema della migrazione evidenziando, attraverso la lettura dei dati Istat, il fenomeno del progressivo aumento della popolazione femminile migrante a Palermo. Esamina quindi, a livello empirico, le statistiche degli ultimi cinque anni relative all'accesso delle donne migranti agli ospedali di Palermo in relazione all'assistenza sanitaria prenatale (1), ai parto (2) e agli aborti (3). Si riferisce a un'ampia letteratura per descrivere il concetto di vulnerabilità e declinarlo in una prospettiva di genere che evidenzia la dimensione multipla di fattori contestuali, situaziona…

Gli Albanesi in Istria (secc. XV-XVIII)

2020

Albanian emigration was a historic phenomenon which extended over a long period, and of which different countries of the inter-Adriatic area were the final destination. Besides different regions in present-day Italy, Istria as well constituted a destination. The Albanians arrived there at the end of the 15th century. According to documents from archives, the Istrian settlement displays the connotations of similar migrations – though the latter were much more complex – across the Italian peninsula. Documents reflect the common organisational skills of various groups of migrants.

Women cross borders: economic migration in contemporary Italian and Polish graphic novels

2014

This article provides a comparative analysis of two European graphic novels of the past decade that focus on the theme of female economic migration, namely Sara Colaone’s Ciao ciao bambina (2010) and Agata Wawryniuk’s Rozmowki polsko-angielskie (2012). By exploring these two distinctive immigrant stories, which depict the Italian migration to Switzerland in the 1950s and the contemporary Polish migration to Britain, respectively, this article illustrates the shifting experiences of mobility in Europe across decades. While the Italian narrative presents the stay abroad as a chance to achieve independence and personal fulfilment, the Polish comic views it as a mere financial opportunity. This…

New chronology for Ksâr ‘Akil (Lebanon) supports Levantine route of modern human dispersal into Europe

2015

Modern human dispersal into Europe is thought to have occurred with the start of the Upper Paleolithic around 50,000-40,000 y ago. The Levantine corridor hypothesis suggests that modern humans from Africa spread into Europe via the Levant. Ksâr 'Akil (Lebanon), with its deeply stratified Initial (IUP) and Early (EUP) Upper Paleolithic sequence containing modern human remains, has played an important part in the debate. The latest chronology for the site, based on AMS radiocarbon dates of shell ornaments, suggests that the appearance of the Levantine IUP is later than the start of the first Upper Paleolithic in Europe, thus questioning the Levantine corridor hypothesis. Here we report a seri…

An exploration of organization dissent and workplace freedom of speech among young professional intra-urban migrants in Shanghai

2017

This study explores the factors influencing the dissent behavior and perceptions of workplace freedom of speech among young Chinese professionals who are intra-urban migrants. It attempts to grasp the role of the Chinese household registration system, referred to as Hukou, in migrants’ professional and everyday life. Fourteen interviews were conducted with young, well-educated intra-urban migrants who possessed middle-income jobs but did not possess a Shanghai registration (Hukou). This study reveals that traditional Confucian values are significant in shaping Chinese migrant workers’ expressions of dissent and perceptions of workplace freedom of speech. Findings from this study demonstrate…

Who Moves to Depressed Regions? An Analysis of Migration Streams in Finland in the 1990s

2002

Depressed regions typically lose a large number of migrants but simultaneously are destination regions for some migrants. This study analyzes those people who decided to move to depressed regions in Finland in 1993-1996. The analysis is based on a 1 percent sample drawn from the Finnish longitudinal census. The results show that migration into depressed regions is also a selective process. Return migration is only one part of this migration. However, the more educated an individual is, the more likely she or he is to move to a flourishing region. The process of concentration of human capital is reinforced by interregional migration.

Exploring Links between Internal and International Migration in Albania: a View from Internal Migrants

2013

Over the last 20years, Albania has experienced sweeping economic and social changes, caused in part by increasing internal and international migration flows. Migration trajectories of Albanians represent a combination of internal, international, and return migration. Whereas scholars have previously focused mainly on international migration, the current research explores the dynamics between internal and international migration. Typically, the internal migration of a family is supported, psychologically and financially, by the international migration of other household members. This paper reports on the influence that social and economic remittances have on the livelihoods of internal migra…

Norms matter! The role of international norms in EU policies on asylum and immigration

2014

Abstract This Article investigates how international norms impact on eu asylum and immigration policy. To this end we scrutinize the assumption that the robustness of international norms indicates the quality of eu integration. Drawing on international norms literature we argue that four characters define an international norms’ robustness: specificity in definition, binding force, coherence with domestic law and international law, and concordant understanding among actors. Our analysis covers three eu policy areas, asylum policy, family reunification policy, and labour migration policy. Across the three areas international norms had varying degrees of robustness at the time of eu negotiat…
