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

Co-Designing Game Solutions for Hybrid Urban Spaces. How Game Elements Can Improve People Experience with the Mobility Services
Digital technologies integrated in the physical spaces enable new
practices that open new possible interactions between people and the urban
public spaces. These emerging hybrid spaces might have a crucial role in the
processes aiming at having a more satisfying urban life. Mobility is a field
strongly impacted by hybrid urban spaces and this should be considered in
order to improve the quality of life in cities. In this paper the authors, starting
from the concept of Mobility as a Service (MaaS), show as game elements
applied in different moments of the travel experience and disseminated in
different elements of these hybrid spaces can enhance the interaction between
people and mobility services. An example of this assumption is shown, by
presenting the outcome of a co-design session, during which a game solution
aiming at improving the people experience with the mobility services is
identified
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
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
Sustainable low-input farming system: the case of Marianis-Volpares farm.
A public farm (630 ha) located in Palazzolo dello Stella (UD) (L at. 45°48”N,Long.13°5’0”E) in the
Friuli Venezia Giulia region of Italy, is managed by ERSA (Agenzia Regionale per lo Sviluppo Rurale) in order
to promote environmentally friendly agriculture. The farm is a complex in which agricultural activities will be in
harmony with the environment and landscape. Hedgerows, ditches, woods, ponds of fresh water, wet meadows
and brackish wetlands will be introduced into the farm. Present high input farming systems (HIFS) is in
transition to low input farming systems (LIFS) using good farming practices (GFP) to qualify the agrienvironment.
Seeds suitable for LIFS will be tested; techniques of soil management such as minimum tillage and
direct drilling will be used. Traditional rotation maize-soybean and maize-lucerne will be integrated with more
environmentally friendly crop rotation systems introducing minor cereals, legumes and multi-species meadows
for ley-arable rotation. Crop rotation will be managed to improve soil fertility and carbon sequestration, to
reduce fertilizing intensity, to protect soil from erosion, to maintain soil organic matter (SOM) and soil structure
and to reduce the use of pesticides. Cover crops will be introduced for manuring and catch crops for reducing
water pollution by nitrates. Crop rotation, soil cover, fertilizing intensity, fertiliser uptake, nitrate leaching, mode
of manuring, landscape elements will be used as main indicators. The present herd of 650 heads of cattle will be
reduced to about 540. Buildings, barns for dairy cows, calving pens, and milking boxes will be restored to
improve animal welfare. Energy will be supplied by anaerobic digestion of organic matter mixed with slurry (codigestion)
by cogeneration and tri-generation processes. Meat, milk and dairy products of high quality will be
certificated by labelling systems
The role of grassland in rural tourism and recreation in Europe
Grasslands are an essential element of sustainable farming systems and are acknowledged as having economic, ecological, social and cultural roles. In many areas raising animals in a grassland-based system is providing farmers with a decent income while in others the only way for farmers to stay in agriculture is to 'cultivate' tourists through agritourism and ecotourism. Agritourism is a particular form of rural tourism, i.e. farmers provide on-farm activities connected to farming. Grassland in a diversified landscape provides an added value for tourists and is the most important resource for tourism development having a greater aesthetic and recreational potential than uniform agricultural areas both in lowlands and mountains. Consumers often perceive food products from extensive and organic grassland-based agriculture as of higher quality. Nature-based tourism (ecotourism) where people visit rural areas characterized by high species and habitat diversity is also an important source of additional income to farmers. Ecotourism generates many economic benefits for local communities and activities related to farming are more attractive, such as the direct sale of products labelled as coming from Natura 2000 sites. Tourism may also have negative impacts when the number of tourists is large or the resources are overused
Dispelling the Myths Behind First-author Citation Counts
We 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
