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 textEnvironmental and digital innovation in food: The role of digital food hubs in the creation of sustainable local agri-food systems
No full textThis document is based on the study of what a local digital food hub is. Topics such as the sustainability of agri-food systems, de-agrarianization and the causes related to them are covered, but also such principles as “shared value”, useful for improving the competitiveness of a company as well as the economical and social conditions within the communities in which it operates. In addition to these discussions, an excursus is created on the actual developments of the models ranging from “field to table”, with the new possibilities obtained from modern types of distribution networks, particularly focusing on Food Hubs and the first reasons for the validity of the system. Having explained these issues, the focus shifts exclusively to the Food Hub topic, defining what it is and what the models used for its different structures are, also based on the social and local contexts in which this reality is located or created. The results of the study highlight the presence of Food Hubs already developed and functioning in the USA, although they are almost non-existent in Europe and Italy where they could be a source of economic recovery in this sector, with the possibility of both digital and non-digital development. The presence of the only concrete example of a food hub in Italy is highlighted. Also, the current problems faced by Italian politics are considered regarding the possible legislative evolutions for the innovation and digitization of businesses, supported by the new financial programs envisaged by the “New Generation EU” European Plan, through which substantial funds have been allocated to Italy, also for the development of digital innovations and the enhancement of Italian products, as well as the “made in Italy” brand

The Design of an Abstract Machine for Subset Equational Languages
No full textMany researchers have been trying to use the implicit parallelism of logic lan-
guages parallelizing the execution of independent clauses. However this approach
has the disadvantage of requiring a heavy overhead for processes scheduling and
synchronizing, for data migration and for collecting the results. In this paper
it is proposed a different approach, the data parallel one. The focus is on large
collections of data and the core idea is to parallelize the execution of element-
wise operations. The target language is SEL, a Subset Equational Language. An
abstract machine for it, the SAM (Subset Abstract Machine), is outlined, which,
under certain points of views, belongs to the WAM family. The data parallel
structure of the SAM and of its instruction set is here explained and some exam-
ples of how it works are given. Eventually some conclusions are drawn and it is
presented the plan for the future research
