Les problèmes sociaux comme comportements collectifs
No full textSocial Problems as Collective Behavior
Herbert Blumer (paper introduced by Laurent Riot)
This paper presents to a French audience a major text in sociology of social problems : H. Blumer's text "Social Problems as Collective Behavior". For Blumer, social problems have their existence in a process of collective behavior. This process determines whether social problems will arise, whether they become legitimized, how they are reconstituted in putting planned action into effect. According to Blumer, sociological theory and study of social problems should respect this process.Les problèmes sociaux comme comportements collectifs
Herbert Blumer (texte présenté par Laurent Riot)
L'article présente à un public français l'un des textes majeurs de la sociologie des problèmes sociaux : celui publié par H. Blumer en 1971 dans la revue Social Problems et intitulé « Les problèmes sociaux comme comportements collectifs ». Selon Blumer, les problèmes sociaux sont le produit d'un processus collectif. Ce dernier détermine les modalités de leur émergence, les façons dont ils sont légitimés, les manières dont ils sont redéfinis pour donner lieu à des actions publiques susceptibles d'effets concrets. La théorie sociologique et l'étude des problèmes sociaux doivent rendre compte d'un tel processus.Blumer Herbert, Riot Laurent. Les problèmes sociaux comme comportements collectifs.

Oriented right-angled Artin pro- groups and maximal pro- Galois groups
No full textFor a prime number we introduce and study oriented right-angled Artin
pro- groups (oriented pro- RAAGs for short)
associated to a finite oriented graph and a continuous group
homomorphism . We show
that an oriented pro- RAAG is a Bloch-Kato
pro- group if, and only if,
is an oriented pro- group

some effort in order to show that oriented right-angled Artin pro- groups
share many properties with right-angled Artin pro--groups or even
discrete RAAG's, e.g., if is a specially oriented chordal graph, then

Positselski-Bogomolov property generalizing a result of H. Servatius, C. Droms

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Evolving Role and Nature of Workplace Leaders and Diversity: A Theoretical and Empirical Approach
No full textBlumer (1962) regarded the ‘many possibilities of uncertainty as inherent to the process of joint action.’ Joint action reflects the efforts of participants to work out the line of action in light of what they observe each other doing. Leadership appears to be approached from two fundamental perspectives: an organisational perspective (the influence that is exercised to change the direction of the organisation), and an individual task perspective (the influence that is directed at changing the work behaviour of an individual). In this article, it is suggested that the symbolic interaction of perspective integrates the two fundamental perspectives in that both perspectives require meaningful, reflexive integration and meaning, group membership, organisational role and experience. The evolving role of leaders to attract, retain and connect with a diverse workforce in a changing environment gives rise to interactive leadership competency requirements. This article suggests that managing diversity requires business leaders to adopt an approach to diversity management that is sensitive not only to race and ethnic differences, but also to the background and values of all individuals at work. The empirical study was done and four hundred and forty (440) leadership styles were measured in eleven (11) organisations. The study used the Hall and Hawker (1988) inventory leadership styles and a diversity questionnaire to measure diversity management experience.discrimination, diversity management, engaging leadership style, experience, heroic leadership style, management, transformational leadership
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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

No full textDispelling the Myths Behind First-author Citation Counts
No full textWe 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
