    Calluna vulgaris communities of Lombardy and Piedmont upper Po Plain, developing on different Quaternary deposits, can be considered one of the most southern example of lowland heathlands in Europe. First outcomes of the vegetation surveys carried out with phytosociological methods, are reported. Vegetation types have been characterised and their relationships with different deposits have been sought. On older deposits major community types belong to Genistion Boch. 1943, while Sarothamnion Tx. in Prsg. 1949 thickets are quite rare. Comparisons with literature emphasized such floristic differences that could lead to their arrangement in a proper sintaxon. Field observations about dominant species behaviour allowed some insight about competitive strategies and autosuccessional patterns, which suggest the partial revision of their ecological meaning

    Il Centro Regionale per la Flora Autoctona della Lombardia.

    Lombardy is characterised by a remarkable variety of plant communities and landscapes that often show a high species richness with the presence of several endemic and rare species. However the region is one of the first areas for density of population, development rate and productive activities in Italy and Europe as well: very particular ecosystems (limestone prairies, lowland heathlands, peat bogs, etc.) often intermingle with towns, factories, quarries and so on. Beyond the traditional enterprises for the conservation of biological diversity based on the creation of protected areas, the regional administration has recently founded the “Centro per la Flora Autoctona” (Wild Plants Centre), whose main aim is the acquisition of knowledge and techniques to warrant the availability of wild shrubs and herbs suited to 1) environmental restoration, and 2) rare and/or endangered species conservation project

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
