Il sito di età del Bronzo di Ca’ Nova di Albareto nel contesto territoriale dell’alta valle del Taro
No full textDurante il II millennio BC, mentre nella pianura l’ intera Emilia condivide la cultura
delle Terramare, nell’ Appennino dell’ Emilia occidentale l’ evidenza archeologica mostra
un’ area di confine tra la cultura delle Terramare e la cultura denominata BINO (età del
Bronzo del Nord-Ovest). Si nota che il numero di siti per Km2 nell’ Appennino parmense
orientale, reggiano e modenese è molto maggiore che in quello parmense occidentale,
pur tendo presente che quest’ ultimo territorio è noto più che altro da ricerche di superficie.
L’ area in cui il confine è stato identificato è la valle del Taro e del Ceno; l’ analisi della
visibilità e inter-visibilità dei siti, condotta in ambiente GIS, aiuta a distinguere i diversi
distretti regionali. L’ importanza dell’ afferenza della cultura materiale del sito di Ca’ Nova
alla cultura BINO (il primo sito scavato puramente BINO, senza testimonianze terramaricole,
sul lato orientale della Val Taro), insieme alla sua posizione apparentemente isolata
incoraggia a studiare l’ intera area circostante anche valutando l’ acclività dei terreni
e applicando la Least Cost Path Analisys (LCPA) per individuare la rete dei percorsi che
connettevano la pianura padana con la Liguria e la Toscana. I risultati di queste analisi,
insieme all’ alto livello di controllo territoriale attribuito al sito dall’ analisi di visibilità,
dimostra che il sito di Ca’ Nova poteva essere strategico per il controllo di un sistema di
strade che incrociavano l’ Appennino per raggiungere risorse importanti quali il sale o il
metallo o, come è documentato per il Medio Evo, per la transumanza.While in the Po Valley in the 2nd millennium BC the Emilian region was inhabited
by populations sharing the same material culture (Terramare culture), in the western
Emilian Apennines the archaeological evidence shows a boundary area between the Terramare
culture and the BINO (Bronze Age of North-West Italy) culture. Even though
the Emilian Apennines are mainly known from surface surveys and finds, it should be
noted that the number of sites per square kilometre in the eastern part of the province
of Parma and in the provinces of Reggio Emilia and Modena is significantly higher than
in the western provinces of Parma and Piacenza, perhaps due to the different settlement
pattern of the two cultures. The area where this boundary has been identified is the
valley of the Taro and Ceno rivers (the latter being a tributary of the former), and a GIS
analysis of viewshed and intervisibility has already been carried out to try to distinguish
the different sub-regional districts. The importance of the cultural affiliation of the material
culture of Ca’ Nova to BINO (the first excavated site with only genuine BINO and
no Terramare material culture in the eastern Taro valley) and its apparently isolated position,
suggested that the wider aerial context of the site should be investigated also using
slope analysis and LCPA to study the possible pathway system that would connect the Po plain with Liguria and Tuscany. The results of these analyses, together with the high level
of territorial control attributed to the site by the viewshed analysis, seem to demonstrate
that the position of Ca’ Nova was highly strategic for the control of a possible system of
routes that crossed the Apennine ridge to reach important resources such as salt or metals,
or (as documented in the Middle Ages) for the movement of transhumant livestock
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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
