Alien flora of Europe: Species diversity, temporal trends, geographical patterns and research needs
2008
International audience; The paper provides the first estimate of the composition and structure of alien plants occurring in the wild in the European continent, based on the results of the DAISIE project (2004–2008), funded by the 6th Framework Programme of the European Union and aimed at “creating an inventory of invasive species that threaten European terrestrial, freshwater and marine environments”. The plant section of the DAISIE database is based on national checklists from 48 European countries/regions and Israel; for many of them the data were compiled during the project and for some countries DAISIE collected the first comprehensive checklists of alien species, based on primary data …
La politique sportive des Emirats du Golfe : comment obtenir une visibilité internationale ?
2006
Les petits Emirats du Golfe Persique ont choisi le sport pour obtenir une visibilité internationale et modifier leur image. Le sport offrait la possibilité d’afficher une modernité souvent associée à l’adoption de valeurs venues de l’Occident. Sans traditions sportives et très peu peuplés, ces Etats ont néanmoins réussi leur entrée sur la scène sportive internationale en mobilisant beaucoup d’argent. Ils ont pu ainsi accueillir et organiser des compétitions sportives internationales de grande ampleur et se faire reconnaître. Leur politique a franchi un nouveau pas, depuis quatre années, en naturalisant des athlètes de haut niveau pour obtenir des médailles car en terme de communication, l’i…
Principi di spontaneizzazione di Diospyros kaki (Ebenaceae) in Sicilia
2013
A spontaneous group of plants of Diospyros kaki is reported in a rural area near Menfi, in the province of Agrigento. This is the first record of naturalization of this Asian species – after long time cultivated in various countries of the Mediterranean Basin - observed in Italy.
A casual alien plant new to Mediterranean Europe: Ceiba speciosa (Malvaceae) in the suburban area of Palermo (NW Sicily, Italy)
2014
The abiotic and biotic characteristics of the first sites where floss silk tree behaves as a casual alien plant in the Mediterranean Europe are described. The species was probably first planted in botanical gardens of southern France few decades before mid XIX century. It was introduced in Palermo in 1896, a city which appears to match very well its climatic requirements. According to the available information on its biology and ecology in both its original and secondary range, the floss silk tree should not become an invasive alien plant in the Mediterranean. Nevertheless, several gaps need to be filled in order to increase our understanding of future trends of Ceiba speciosa in southern E…

Accessing Citizenship: The Conceptual and Political Changes of the German Naturalization Policy, 1999–2006
2014
This article deals explicitly with the dimension of access in the concept of citizenship and is discussed from the point of view of migration. Access is analyzed in the context of the reform of German citizenship laws in 1999. The state of Hesse is singled out to be used as an example of parliamentary debate on the concepts of citizenship and integration. The point is to explicate the interrelations of the federal legislative reform and the conceptual implications thereof, using a statelevel example (Hesse). peerReviewed
Principi di spontaneizzazione in Sicilia di Aesculus hippocastanum (Hippocastanaceae)
2009
The first record of Aesculus hippocastanum naturalized in Sicily is presented from a locality near the Alcantara river (Floresta, Messina) in the montane belt where decidous Turkey oak and chestnut woods are found. This species is not frequently cultivated in Sicily. In that locality several mature individuals likely introduced several decades ago occur.
Ecologia e distribuzione di Chamaerops humilis L. (Arecaceae) nella Sicilia nord-orientale
2014
I settori costieri e collinari della Sicilia nord-orientale e delle Eolie sono stati esplorati ai fini della raccolta di informazioni aggiornate sulla distribuzione dei popolamenti di palma nana e sulle caratteristiche ecologiche delle stazioni che li ospitano. I risultati delle indagini di campo sono stati integrati dalla verifica dei toponimi locali legati ai nomi dialettali della specie. Si con- ferma la totale assenza della palma nana lungo l’intero settore costiero dei Nebrodi. Dei nove popolamenti accertati, quattro si trovano alle Eolie, due sul versante ionico e tre sul versante tir- renico dei Peloritani; uno di questi ultimi, localizzato su Capo Calavà, risulta inedito. La conco- …
De-naturalizing the “predatory”: A study of “bogus” publications at public sector universities in Pakistan
2022
Predatory publishing has recently emerged as a menace in academia. University professors and researchers often exploit this practice for their economic gains and institutional prestige. The present study investigates such existing predatory publishing practices in Pakistani public sector universities using Bourdieu’s (1991) concept of symbolic violence. For this purpose, we analyzed 495 articles published by 50 university professors in the social sciences and humanities over the period 2017-2021. We also conducted semi-structured interviews with 20 postgraduate students to gather their perspectives on publishing practices. The study shows that 69% of the sample papers were published in pred…
