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
Living with COVID-19: emotions and health during the pandemic
No full textBACKGROUND COVID-19 has led and still leads all nations to adopt virus containment plans, considering possible strategies that help to live with the virus. The present study aimed to investigate the practical, psychological and emotional aspects of living with COVID-19. PARTICIPANTS AND PROCEDURE A total of 250 young adults (86% female), who lived in north-western Italy, took part in an online photovoice study, in respect of social distancing. They participated in a group discussion following the method SHOWeD. The researchers analyzed the photographs along with comments and transcripts from the SHOWeD group discussions using the triangulation process of visual and textual data. The collected data were analyzed on the basis of grounded theory, with the support of the NVivo 12 software. RESULTS From the analysis of the emotions concerning the psychological health of participants, 4 categories were identified. The results reveal benefits and emotional aspects that have stimulated the increase of individual and community empowerment. COVID-19 has led and still leads all nations to adopt virus containment plans, considering possible strategies that help to live with the virus. CONCLUSIONS From the analysis of the results it emerged how the online photovoice was a tool that allowed on the one hand the sharing of experiences and emotions related to living with COVID-19 and on the other hand to maintain social ties despite physical distance
Reflective Practices to Study Group Dynamics: Implement Empowerment and Understand the Functioning of Groups
No full textIntroduction: Individual and group reflection practices are qualitative methods useful in a group context to develop group skills and more awareness of the dynamics that take place within the group to which one belongs. Aim: The aim of this work is to highlight how individual reflective practices and group reflections contribute to the development of group skills. More specifically, the effectiveness of relevant group dynamics is investigated, with the aim of creating a space for reflection, and activation for individual and group empowerment. Participants: The participants were 130 university students (86% female), resided in northwestern Italy, and had a mean age of 27.5 years (SD = 7.52). They were randomly divided into 23 groups (ranged from four to nine members). Method: The participants engaged in several online training activities and at the end of every activity they completed individual reflection practice in which they presented both positive and negative aspects related to the group experiences. Then they participated in online group reflections that allowed them to reflect on the group dynamics, particular attention given to factors such as climate, participation and roles played by each participant in a variety of training activities. This study analyzes 130 individual reflective practices and 23 group reflections. The data collected through individual reflective practices and the transcripts of the group reflections were analyzed using grounded theory. Two independent judges analyzed and categorized the data and then identified the main common categories that emerged by the support of Nvivo software. Results: From the analysis of the content, it is determined that the participants, based on the construction of the individual and group reflections, paid greater attention to the dynamics that occurred within the group during the various activities in which they participated, thus allowing them to be more aware of the various factors that affected the importance attributed to the different roles, the climate, and their active participation. Conclusion: Combined, these factors allowed participants to strengthen their relationships with each other and enhance the cohesion of the group
Experimental characterization of dedicated front-end electronics for piezoelectric tactile sensing arrays
No full textEmbedding electronics with tactile sensors may enable electronic skin to be applied in many domains such as prosthetics, robotics, industrial automation. The complexity of electronics from size and power consumption point of view represents the main barrier towards achieving goal. This paper provides the experimental characterization of dedicated front-end electronics for piezoelectric tactile sensing arrays. Aiming to decrease the hardware complexity, the designed circuits are based on the DDC112U and an FPGA Xilinx Spartan-6 devices. An experimental setup has been implemented to acquire the signal generated from a tactile sensor. Results validate the functionality of the proposed interface when the measured voltage and charge are analyzed in terms of the input force. Experimental characterization demonstrates the correctness of the results when the signal to noise and distortion (SINAD) ratio, and the effective number of bits (ENOB) have been analyzed
Parenting in migration: Critical aspects and challenges of “doing family” of refugee families and social workers
No full textSummary: Although migrant families comprise a small number of immigrants, they present a significant challenge for the host community. In the Italian context, social services support migrant families through paths to autonomy and integration in the community. The purpose of this study was to investigate perceptions that families and social workers have of “parenting” and “doing family” (training and management of family identity, roles and daily practices) in the complexity of migration. The study involved 15 immigrant parental couples, using family interview techniques and 12 social workers in 3 mini-focus groups. The collected materials were transcribed verbatim and analyzed using grounded theory. Findings: The main results are identified and discussed as strengths, critical points and challenges. Some of the themes such as “willingness to work” or “lack of job opportunities” are common to both family members and social workers. Other themes are relevant to one group only. Among these, “availability and support of social workers” only emerged among families, whereas “education and respecting the rules” only emerged among social workers. Applications: The results indicate that it is necessary for social workers to engage in a meaningful helping relationship with families, build networks of inclusion services, and also with the support of mediators overcome linguistic and cultural barriers. Social workers should involve families throughout he integration process. Furthermore, social services must also consider how families experience the difficulty of relating to social workers, which represents an obstacle to support for social integration
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
