Experiments and dialogue are pushing agendas
No full textIn 2004, the Danish researcher Søren Riis and his business partner Matias Mølgaard were students in Germany. Inspired by the well-coordinated carpooling system, Mitfahrzentrale, they conceptualized and founded GoMore. GoMore is now the biggest car sharing and carpooling company in Denmark with growing markets all over Scandinavia and in Spain. GoMore is the first company to combine ride sharing and car sharing in one system. In this conversation with Katrine Hartmann-Petersen, Søren Riis elaborates on his experiences on sharing economies and the future of sustainable urban mobilities
Mobility in daily life - The car and use of information and communication technology for family logistics
Get PDFThe development of “new” family structures, with an increasing portions of divorced parents choose joint custody of the children, and a differentiation and distribution of daily activities has opened the way for new and more flexible forms for information and communication technology (ICT) to coordinate the interaction between family members. The need for flexible transport to link together activities is also an issue. The point of departure for this paper is to examine the interaction between the uses of ICT, in particular mobile phones, physical mobility and social life in an increasingly differentiated and distributed daily life among families with children. The questions addressed are how different families use ICT to coordinate and maintain relationships in everyday life and how ICT and physical mobility interact within this context. The empirical analysis is based on in-depth interviews of 25 families in the Oslo region. The analysis of the interaction between the car and the mobile phone indicate that the one will not replace the other. It is rather such that they represent technologies that complement each other and can perhaps mutually increase use. While the car is an extension of the body and which increases the physical range of the individual, the mobile telephone increases one’s range of overview. To some degree the mobile telephone directs automobile use, in the sense that it may generate more trips since use of the mobile telephone means that there is not the need to plan daily activities. More of the activities are carried out spontaneously and daily life is more ad hoc, which also indicate more car uses. In the families of this study different time use arrangements are tied to the use of the car and the mobile telephone. At the one extreme we find the structured where all the activities are planned – both in time and space – and all the assignments are divided between the various members of the family. On the other hand we see families where everything is done spontaneously and there is very little planning aside from the fixed portions of life. The structured and ad hoc systems are two extremes on a scale where there are many alternative solutions. The families in this study represent positions between the extremes tending towards the ad hoc end of the spectrum. The car and the mobile telephone are devices that allow this type of organization, which seems to increase daily transport by car.
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
