Spontaneous Spatiotemporal Ordering of Shape Oscillations Enhances Cell Migration
2019
The migration of cells is relevant for processes such as morphogenesis, wound healing, and invasion of cancer cells. In order to move, single cells deform cyclically. However, it is not understood how these shape oscillations influence collective properties. Here we demonstrate, using numerical simulations, that the interplay of directed motion, shape oscillations, and excluded volume enables cells to locally "synchronize" their motion and thus enhance collective migration. Our model captures elongation and contraction of crawling ameboid cells controlled by an internal clock with a fixed period, mimicking the internal cycle of biological cells. We show that shape oscillations are crucial f…
Market Values and Socioeconomic Mixité in Palermo. The Role of Migrants in the Commercial Real Estate Market
2022
Socioeconomic and functional mixité has been an objective placed at the basis of urban development to guide the transformation processes of urban areas, associating it with social inclusion as opposed to the morphological and spatial segregation, often caused by monofunctional zoning. The implementation of social mixité involves all social groups and, particularly, migrant communities that, in turn, are formed by groups with different cultures, nationalities, resources and income levels. The location choices of migrants and native residents produce an ever-changing urban geography of residential, commercial and service activities that directly impact on the real estate market. Migrants’ act…
Labour market response to globalisation: spain, 1880-1913
2010
Abstract This paper analyses the impact of globalisation (trade and migration) on the Spanish labour market between 1880 and 1913 by examining the influence that globalisation factors had on agricultural and industrial wages. Our results show that the nineteenth century grain invasion had a negative impact on agricultural wages, whereas the fall in wheat prices did not benefit industry workers. We also found that migration pushed up real agricultural and industrial wages. As agriculture was the main sector in the economy, the final impact was a wage decrease. The negative impact of trade on agricultural and industrial labour markets partly explains the trade policy response of “integral pro…
Saperi e abilità in chiave interculturale. Risultati di una ricerca empirica con esperti del sistema di accoglienza dei migranti in Italia.
2020
In pedagogia, il “paradigma delle competenze” costituisce uno dei riferimenti essenziali. L’aspirazione verso un profilo completo della competenza è frutto di una ricerca costante di equilibrio fra teoria e pratica, fra etica e tecnica. Nei contesti educativi con persone migranti, agli operatori dell’accoglienza sono richieste, oltre alle conoscenze, abilità attea saper gestire l’interazione con chi presenta dei profili linguistici e culturali diversi. Il contributo intende riflettere sulle competenze proprie dei professionisti del sistema di accoglienza e di protezione in Italia. Nello specifico, l’obiettivo è quello di presentare i risultati di una ricerca esplorativa sulle competenze int…
Executable Data Quality Models
2017
The paper discusses an external solution for data quality management in information systems. In contradiction to traditional data quality assurance methods, the proposed approach provides the usage of a domain specific language (DSL) for description data quality models. Data quality models consists of graphical diagrams, which elements contain requirements for data object's values and procedures for data object's analysis. The DSL interpreter makes the data quality model executable therefore ensuring measurement and improving of data quality. The described approach can be applied: (1) to check the completeness, accuracy and consistency of accumulated data; (2) to support data migration in c…
Confin(at)i Mediterranei e Afroamericani. Una performance geografica sulla disumanizzazione
2020
Studiare la questione mediterranea soltanto dentro le aule universitarie non ci permette di restituire una realtà sfaccettata che viene proposta all’opinione pubblica con un’unica parola d’ordine: invasione. La performance E l’Europa disumanizzò se stessa mi ha permesso di presentare la storia di schiavi e fuggitivi per un’audience più vasta. Incentrata sul libro di Toni Morrison, Beloved, rimbalza tra gli effetti delle storie dell’Atlantico Nero e quelli dell’odierno Mediterraneo. Il saggio si propone di tracciare alcune direzioni che possano aiutare a indagare le diverse linee di confine che segnano la rugosità della modernità del nostro globo. Per fare questo, si prova a rispondere a tre…
Landscape-scale Spatial Distribution of the Lanner Falcon (Falco biarmicus feldeggii) Breeding Population in Italy
2008
Falco biarmicus feldeggii is one of the most threatened taxa in Europe. Its global population is estimated at a few hundred pairs unequally scattered in a vast and fragmented area stretching from Sicily to the Caspian Sea. Most recent counts showed that Italy hosts a large part (>25%) of the whole population. Consequently, Italian authorities promoted a national action plan. In this framework, we carried out the first national survey for the Lanner Falcon in Italy (2003-2004). Our study area covered the whole breeding range, i.e., Sicily and the Italian peninsula (n = 2909 cells 10 × 10 km). When possible, we considered also additional information from previous regional investigations (1993…

Care facilities for Germans in Thailand and Poland: making old age care abroad legitimate
2019
This article looks at old age care facilities abroad that target people who live in Germany. Such facilities have been established in Southeast Asia (mainly Thailand) and in Eastern Europe (mainly Poland). Given that they challenge central guiding orientations for old age care in Germany, considerable criticisms are levelled at them, and their use is viewed with distinct scepticism. Nevertheless, some of these facilities succeed in sustaining considerable demand from Germany over quite a few years. In this article, we therefore ask what strategies and arguments they use to make them a legitimate option for people in Germany and to be established on the German market. Based on two case studi…
Live-in migrant care worker arrangements in Germany and the Netherlands. Motivations and justifications in family decision-making
2019
Private households in ageing societies increasingly employ live-in migrant carers (LIMCs) to care for relatives in need of 24/7 care and supervision. Whilst LIMC arrangements are a common practice in Germany, they are only recently emerging in the Netherlands. Taking this development as a starting point, this study uses the countries’ different long-term care (LTC) regimes as the analytical framework to explore and compare the motivations and justifications of German and Dutch family carers who opt for an LIMC arrangment. Findings show that Dutch and German LTC regimes impact differently the decision-making processes of families, as well as on patterns of justification, through a combinatio…
