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
Loneliness among older adults: Detection through technology and reminiscence-based interventions
No full textCompendi d'articlesThis doctoral thesis explores loneliness in older adults through a proof-of-concept approach integrating technological detection and reminiscence-based interventions. The first aim was to develop and assess digital methodologies for detecting loneliness, including the validation of a chatbot-administered version of the 6-item De Jong Gierveld Loneliness Scale and the exploration of machine learning models for identifying linguistic patterns associated with loneliness. The second aim focused on reminiscence as an intervention strategy, comprising a systematic review following PRISMA guidelines and a pilot group intervention for adults over 60. Findings suggest that chatbot-based assessment and language models show promising potential for scalable detection, while reminiscence interventions may help reduce emotional loneliness and enhance psychological well-being. Although exploratory, the results highlight significant research gaps and point toward the value of combining technological and human-centered approaches to better address loneliness in later life.Programa de Doctorat en Psicologi

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
La situación social de las personas mayores en Castellón de la Plana: Un estudio diagnóstico
No full textTreball Final de Grau en Psicologia. Codi: PS1048. Curs: 2016/2017Along with the ageing of the population and the rapid urbanization societies face new challenges.
Following the World Health Organization (WHO) project, the Global Network for Age
-
friendly Cities
and Communities, the objective of this study is to diagnose
the social situation of Castellón
́s elderly. The
data was obtained using the survey method. The research team designed a questionnaire to evaluate the
eight interconnected domains, proposed by the WHO, which are characteristic of Age
-
friendly cities. This
study evaluates three of the eight domains: Social participation, respect and social inclusion, and civic
participation. A cluster sample was carried out to select between diverse elderly centers from
Castellón.The sample was constituted by 203 people olde
r than 60 years, from which 55% are women
(112) and 45% men (91). The total average age is 74,46 years.
The sample is representative with a
statistical confidence level of 95%, a statistical margin of error of 7%
and
p=q.
Results show Castellon ́s

between
genders, age groups,
nor between people who cohabit
and those who live alone. It is c

that there is a need to improve the social situation of
the city. We propose
the Town H

should take actions to increase so

of th

health and
life quality.Junto con el envejecimiento poblacional y el rápido proceso de urbanización llegan nuevos retos a los que
la sociedad debe enfrentarse. Siguiendo el Proyecto de Red Mundial de Ciudades Amigables con las
Personas Mayores, establecido por la Organización Mun
dial de la Salud (OMS); el objetivo de este
estudio es hacer un diagnóstico de la situación social de la tercera edad en Castellón de la Plana. Los
datos se obtuvieron a través del método de encuesta. El equipo de investigación diseñó un cuestionario
para
evaluar las ocho áreas temáticas que componen una ciudad amigable según la OMS. Este estudio
evalúa tres de las ocho áreas de investigación: La
‘
participación social
’,
el
‘
respeto e inclusión social

‘empleo y

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
