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
Cyber- and traditional bullying as global challenges? Findings from Germany, Hong Kong, and Japan
Get PDFBullying, including cyberbullying, constitutes a worldwide phenomenon
with grave consequences for well-being, mental health, and educational
outcomes (Kowalski et al. 2014; Kowalski & Limber 2013; Schunk et al. 2022). In
2014, the General Assembly of the United Nations adopted a resolution that
recognized bullying as a global concern and encouraged member states to take
measures for preventing and responding to bullying (UN General Assembly
2014). Marta Santos Pais, UN Special Representative of the Secretary-General
on Violence against Children, emphasized the importance of reducing bullying
for attaining the Sustainable Development Goals, saying that ‘preventing and
addressing bullying will no doubt contribute to the promotion of the safe and
non-violent learning environments and to the elimination of physical, sexual and
emotional violence that the [Sustainable Development Goals] seek to guarantee'
(UN News 2015). Research on cultural differences in cyberbullying has grown in
recent years, given that cyberbullying is a global phenomenon (Sittichai & Smith
2015). Yet, research on cyberbullying is still typically conducted within a culture
as opposed to across cultures. This chapter explores the role of culture in
shaping bullying and presents empirical findings based on direct comparisons
among university students from Germany, Hong Kong, and Japan
Sustainability and Adaptation in Planning: Community Resilience Against Accelerating Environmental Change
Get PDFUrban and regional planning can be both the context and an instrument to create and foster resilience on the scale of the city, district, or neighborhood, against the background of growing and increasingly compounded climate-related and socio-economic uncertainty and risk. How can planning help communities cope with and adapt to the related societal and spatial challenges? Why is resilience relevant to sustainable planning in the context of adaptation to accelerating environmental risk and how can it be ‘built’ into formal planning

Weak solutions for unidirectional gradient flows: existence, uniqueness, and convergence of time discretization schemes
No full textWe consider the gradient flow of a quadratic non-autonomous
energy under monotonicity constraints. First, we provide a notion of
weak solution, inspired by the theory of curves of maximal slope, and
then we prove existence (employing time-discrete schemes with differ-
ent implementations of the constraint), uniqueness, power and energy
identity, comparison principle and continuous dependence. As a by-
product, we show that the energy identity gives a selection criterion
for the (non-unique) evolutions obtained by other notions of solutions.
Finally, we show that for autonomous energies the evolution obtained
with the monotonicity constraint actually coincides with the evolution
obtained by replacing the constraint with a fixed obstacle, given by the
initial datum
