Mobilities, Boundaries, Religions: Performing Comparison in the Mediterranean
No full textThe aim of this article is to provide a discussion on the Mediterranean as a helpful framework for comparison. In order to illustrate what kind of comparison we have been thinking of, we will be dealing with two case studies that investigate the relationship between mobility and religious identities. The first case study focuses on mobility across Greek and Albanian border regions, whereas the second investigates migration from rural areas of Morocco to rural areas of central Sardinia (Italy). The theoretical ground in which the research is situated merges approaches on migration to southern Europe (Grillo and Pratt 2002, Cesari 2002), approaches on borderlands, and reflections on boundaries as analytical tools (Donnan and Wilson 1999), and finally focuses on the social meaning of religious identity
A new deal for Advances in Oceanography and Limnology (AIOL Journal)
Full text linkWith this first double issue of 2015, Advances In Oceanography and Limnology (AIOL Journal) is facing an important regime shift. Published in house until 2007 by the Italian Association of Oceanography and Limnology (AIOL, www.aiol.info) as the Proceedings of the AIOL National Congress, it has been transformed starting from 2011 in a regular scientific journal with the aim of offering a new publication outlet for oceanographers and limnologists...

No full textThe trophic biology of the holothurian Molpadia musculus: implications for organic matter cycling and ecosystem functioning in a deep submarine canyon
Full text linkMegafaunal organisms play a key role in ecosystem functioning in the deep-sea through bioturbation, bioirrigation and organic matter cycling. At 3500 m water depth in the Nazaré Canyon, NE Atlantic, very high abundances of the infaunal holothurian Molpadia musculus were observed. To quantify the role of M. musculus in sediment cycling, sediment samples and holothurians were collected using an ROV and in situ experiments were conducted with incubation chambers. The biochemical composition of the sediment (in terms of proteins, carbohydrates and lipids), the holothurians' gut contents and holothurians' faecal material were analysed. In the sediments, proteins were the dominant organic compound, followed by carbohydrates and lipids. In the holothurian's gut contents, protein concentrations were higher than the other compounds, decreasing significantly as the material passed through the digestive tract. Approximately 33±1% of the proteins were digested by the time sediment reached the mid gut, with a total digestion rate equal to 67±1%. Carbohydrates and lipids were ingested in smaller amounts and digested with lower efficiencies (23±11% and 50±11%, respectively). As a result, the biopolymeric C digestion rate was on average 62±3%. We estimated that the population of M. musculus could remove approximately 0.49±0.13 g biopolymeric C and 0.13±0.03 g N m?2 d?1 from the sediments. These results suggest that M. musculus plays a key role in the benthic tropho-dynamics and biogeochemical processes in the Nazaré Canyon.<br/

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
