Language and Identity in Diaspora Communities: The Case Of Bristalians
No full textThe doctoral thesis presented by Anna Gallo is a sociolinguistic analysis carried out on a small group of British Italian migrants settled in Bristol. Scholarly research has so far concentrated on Italian migrants in the USA, Canada and Australia, but has overlooked investigation of British-Italian varieties in the UK, with particular reference to the south-west of England. The high density of Italian migrants in Bristol (as compared with other migrant communities from Asia and Africa) has been one of the compelling reasons for this doctoral dissertation, especially given the lack of recent studies on their language behaviours as well as their sociocultural identity. Moreover, sociolinguistic studies on Italian migrants in English-speaking countries have mostly been focused on the code-mixing of English and standard Italian, while this doctoral dissertation also takes into account the use of dialects and fully acknowledges their sociocultural significance in speakers’ exchanges
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textPeriodic perturbations with rotational symmetry of planar systems driven by a central force
Full text linkWe consider periodic perturbations of a central force field having a rotational symmetry, and prove the existence of nearly circular periodic orbits. We thus generalize, in the planar case, some previous bifurcation results obtained by Ambrosetti and Coti Zelati. Our results apply, in particular, to the classical Kepler problem
Radial periodic perturbations of the Kepler problem
No full textWe consider radial periodic perturbations of a central force field and prove the existence of rotating periodic solutions, whose orbits are nearly circular. The proof is mainly based on the Implicit Function Theorem, and it permits to handle some small perturbations involving the velocity, as well. Our results apply, in particular, to the classical Kepler problem
