Object-Oriented Techniques for Land Use/Cover Classification:Application of Metaponto Area (Basilicata, Southern Italy)
Full text linkSustainable management of natural resources requires
constant and detailed monitoring of various aspects of the
environment. Land use/cover mapping is considered a key element
for planning protection, management and monitoring of semi-natural
areas in urban ecosystems. Hence the importance of the information
acquired through Remote Sensing, airplane and satellite, has been
recognized for decades. The Remote Sensing data offers notable
advantages for territorial monitoring, particularly of the vegetated
areas, in comparison with data collected on the ground. The study of
the spectral response of vegetation gained from airplanes or satellites
makes it possible to obtain useful information about plant species and
their conditions (density, vegetative state, etc.) in repetitive synoptic
images. The research was carried out over an area of study in
southern Italy (Basilicata, Metaponto area) near the mouth of the
Basento River. For this area, synchronous and geometrically corecorded
aerial photographs and Landsat TM image covering the
period May 2004, were developed. Firstly a preliminary analysis was
carried out using unsupervised means of classification with the aim of
grouping together clusters of multi-band spectral responses that are
statistically distinctive. Following this and after having properly
defined the levels of segmentation of Landsat images using aerial
photographs as a reference, a supervised classification procedure was
applied, first pixel-oriented and then object-oriented, obtaining a
marked improvement both in accuracy and in the reduction of the
“salt&papper” effect of the map obtained by the Maximum
Likelihood classifier

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
