No full textThe olive is a medium-sized evergreen tree, which integrates a unique set
of morphological and developmental characteristics suited to the relatively
dry, rustic conditions of its Mediterranean origin. Also particular to the
olive tree are its numerous small fruits, which are rich in oil that is highly
appreciated for both flavor and health benefits. The Olea europaea species
includes both wild and cultivated forms, and both a long period of
domestication and the perseverance of wild varieties provide a range of
morphological variation, as does the developmental plasticity of this
species. This chapter reviews the general growth and taxonomy of the
olive tree and describes its vegetative and reproductive morphology and
anatomy. Basic structural features of the trunk and branches, leaves, roots,
flowers, fruits, and seeds are described. Current research is indicated for
the structures discussed, and information provided regarding adaptive
significance, environmental influences, and genetically based variability
among cultivars or between wild and cultivated genotypes
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
Variations on the Author
Full text link“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
Tematica I - Manuale per l'identificazione e il riordino del patrimonio varietale di olivo
No full textGenetic relationship among cultivated and wild olives revealed by AFLP markers
No full textThe cultivated and wild forms of olive represent one of the widest and well preserved genetic system among fruit crops. In fact over 2000 varieties of olive are still under cultivation and wild olives represent an important component of the Mediterranean maquis. To date the level and distribution of the entire variability, especially at molecular level, were never evaluated. The study of olive diversity could instead represent a powerful tool to monitor the presence within the wild germplasm of agronomically interesting traits, to explore strategies for the introgression of such traits into the cultivated genotypes and to understand the potentiality of new gene combinations. Our study compared wild olives coming from different sites with some widely cultivated varieties. The within and between groups variability was tested and it was possible to observe that varieties and wilds clustered separately. Two types of wild olives were recognized: one showing a higher relatedness with the cultivars and a second one with a molecular profile clearly different from both cultivated and other wild plants. The samples coming from Sicily, Sardinia and Corsica belonged to the first type while the wild plants collected in Apulia showed a higher range of variability and, for some of them, the belonging to the 'oleaster' form of Olea europaea was hypothesized
PRIMI RISULTATI NELLA TRASFORMAZIONE GENETICA DELL’OLIVO MEDIANTE L’IMPIEGO DI AGROBATTERI.
No full textSi è cercato di individuare le migliori condizioni per trasformare tessuti di cultivar di olivo mediante Agrobacterium timefaciens ingegnerizzato, contenente il gene reporter GUSint o i geni rol A,B,C /ORFs 10.11.12) del T-DNA dell'Agrobacterium rhizogenes 1855 ed entrambi il gene per la resistenza alla kanamicina NPTII. L'espressione del gene GUS è stata rilevata su callo e piccioli fogliari con l'esame istologico, mediante colorazione con XGLUC, evidenziando, in entrambi i casi, trasformazioni chimeriche
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
