Social leadership : come i social media cambiano il modello di leadership nelle organizzazioni
No full textDeveloping Social Leadership: Cultural and Technological Influences
No full textThe development of social leadership is triggered by the adoption of social media for internal purposes by organizations. It involves dynamics of collaborative and mutual influence between leaders and followers, and among followers themselves, mediated by social media. The aim of this paper is to analyze individual attitudes to social leadership as a function of cultural and technological factors. Using data collected from a sample (N=178) of employees, we developed and adapted multiple item scales from a wide range of sources in the literature to assess organizational culture, information technology and social media adoption, in addition to other individual and organizational variables. Regression analysis was used to investigate the relationship between these variables. What emerged was a three-dimensional model of social leadership as a positive attitude towards: shared responsibility, social media usage and direction. In particular, organizational culture strongly influenced two of these three dimensions, while the use of social media for personal purposes predicted attitudes to the use of social media in organizations
Perceived training needs for effective virtual teams: an exploratory study
No full textThe aim of this exploratory study is to identify virtual teams’ members training needs in order to highlight the role of the HR function in supporting them. Three aspects have been taken into account: the needs and challenges related to early stages of virtual teams’ membership; the factors likely to affect the effectiveness of virtual teams with a specific focus on training needs; the role of the HR function in the development of the right knowledge and skills for effective virtual teams. The research questions addressed are: what are the perceived benefits and challenges related to the early stage of virtual collaboration? What are the training needs perceived by virtual team members ? How can the HR function sustain virtual teams’ effectiveness? A qualitative approach based on Bal&Gundry’s model has been adopted. Results of five interviews to Nielsen TAM Italy’s virtual team members are presented and future research steps are suggested
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
