No full textThermodynamic analysis of ceramics production in Sassuolo (Italy) from a sustainability viewpoint
No full textWe present a thermodynamic analysis of the sustainable use of resources in the province of Modena, focusing the attention on the district of Sassuolo. The methodology that is used is the emergy evaluation. The analysis shows that the Sassuolo district represents the peak of non-sustainability of the whole area, with a huge consumption of non-renewable primary resources, both imported and local. The role of the ceramic tile industry is relevant in the consumption of energy and materials. Different types of factories for ceramics production are compared, representing a good sample of different methods of production. Emergy analysis shows which of these has higher levels of sustainability with respect to the others

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
Perceived benefits of littoral wetlands in Uganda: a focus on the Nabugabo wetlands
No full textWetlands, commonly called swamps in
Uganda, are estimated to cover about 13% of the total
land surface area (about 30,000 km2) of the country
and represent a considerable ecological, social and
economic value. In 1989, the Ugandan government
formerly recognised that wetlands need to be conserved
and contribute considerably to the National
economy and rural livelihood. The present analysis is
focused on the Nabugabo wetland ecosystem.
Located in Central Uganda, it is an important part
of the extensive system of wetlands that surround
Lake Victoria. The Nabugabo wetland is a source of
important resources that are basic to the local
economy, including fishing, water utilization, agriculture,
livestock, wetland plants for construction and
more recently, tourism. Investment in the area is low
and a large percentage of the local community
depends on the wetland resources for basic sustenance
needs. After achieving Ramsar status,
demarcation and conservation activities were initiated
by the local and national leaders. However, these conservation efforts have provoked conflicts between
the land owners and the policy makers, in particular
to the demarcation of areas for conservation In the
present analysis, we examine the benefits, perceived
by local leaders and community members, of the
wetland and its services, as well as views towards its
conservation and management. The results show that
differences between the community leaders and
member exist regarding the perceived benefits of
the wetlands. Tourism, while providing some opportunities
for local persons is not always viewed
positively. Conservation activities are viewed positively
but some questions remain as to whether such
efforts help or hinder the local population, in
particular regarding access to basic resources
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
