The Current Significance of Risk
Full text linkAbstract
Risk is to do with uncertainties: possibilities, chances, or likelihoods of events, often as consequences of some activity or policy. As such, risk has always accompanied the development of human society (Sahlins 1974; Garnsey 1988; Gallant 1991). Harvest failure, pestilence, migrations, new currents in religion, technological developments, and the unforeseen consequences of urbanization have all exerted a powerful and typically unpredicted influence on the problems and difficulties we face.
Risk as an Interdisciplinary Research Area
Full text linkB1 - Chapter in Research BookAbstract
Risk issues initially attracted attention as the growing complexity of technical processes and enterprises generated interest in practical problems of risk management. Two factors—the realization that accidents and errors were not simply technical issues, and the increased opposition of members of the public to innovations—directed attention to psychological and sociological approaches to risk. As theoretical and empirical work developed, researchers from different perspectives recognized the importance of the sociocultural embeddedness of risk perceptions.
Citizenship and Old Age: The End of the Road?
No full textThis paper is concerned with the interlinked issues of citizenship and the structured dependency of older people within Social Gerontology. It argues that implicit in much British Social Gerontology is a strategy of advancing the wellbeing of elderly people through the extension of citizenship rights. Absence of these rights leads to poverty, exclusion and ageism being commonplace experiences of large sections of the older population. This approach draws heavily on the ideas regarding social citizenship of T. H. Marshall who has influenced much mainstream social policy in Britain since 1945. Changes to the Welfare State since 1979 have seriously questioned the validity of this approach and many of these criticisms apply to the structured dependency approach. Recent work on citizenship can help us to see how the relationship between old age and citizenship has changed and how far theory in social gerontology needs to change to take account of these new circumstances
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
