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
Understanding How to Change: An Inductive Determination of How Agents of State Government Plan, Lead, and Sustain Change
Full text linkThis dissertation started with a simple question: Why is it so difficult to lead successful organizational change initiatives? The dynamics of organizational behavior support a plethora of complex answers to this simple question. Indeed, literature abounds regarding the need for organizational change, individual transformation, and living system adaptation. However, Jaworski, Gozdz, and Senge (1998) noted that although much has been written about organizational change, there is little offered in literature about how to achieve change. Beer and Nohria (2000) added that existing organizational change theory is not sufficient to address organizational transformation especially relative to the people side of change. Wall (2004) echoed in this void claiming there is still no practical organizational change process, technique, or formula available to plan, lead, and sustain change. This brief literature suggests that organizational change is difficult due in part because there is not a clearly practical explanation of how to change. Thus, the grand aim here is to provide an understanding of how to change, and offer what is commonly referred to as change implementation theory (Bennis, 1966). The research approach to accomplish this aim took a constructivist knowledge claim position in that theory generation is the goal. The strategy of inquiry followed a qualitative research method using grounded theory protocols. Theory building was data driven largely from expert interviews. However, existing literature and emerging approaches were also employed along side constant comparative analysis throughout the study. The result is detailed herein as an organizational change implementation theory and utilitarian change leadership field guide regarding how best to plan, lead, and sustain organizational change
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
The Moderating Effects of Power Distance and Individualism/Collectivism on Empowering Leadership, Psychological Empowerment, and Self-Leadership in International Development Organizations
Full text linkThe importance of finding appropriate leadership styles to use in cross-cultural situations is paramount. Development organizations and multinational organizations both struggle to find forms of leadership that are effective in mobilizing the workforce in highly diverse cultural contexts. In this article, the effects of empowering leadership on psychological empowerment and self-leadership are measured in two cultural contexts—Rwanda and the United States, representing both high and low power distance and individualism/ collectivism—to explore how empowering leadership behaviors affects the empowerment of subordinates. First, hierarchical regression analysis shows that empowering leadership has a significant positive effect on both psychological empowerment and self-leadership in both cultural contexts. Second, hierarchical regression analysis with tests for moderation shows that power distance moderates these relationships, especially in high power distance cultures, while individualism/collectivism moderates these relationships only occasionally. This article provides evidence that empowering leadership is an effective form of leadership that produces employee empowerment in diverse cultural contexts. It also provides new insights into appropriate forms of leadership for international development organizations when working in different countries
