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
The role of attachment dimensions and perceived social support in predicting adjustment to cancer
No full textObjective: Several studies carried out over the last years show that patients' adjustment is very important to the past experiences of people with cancer. In our study of 96 subjects with cancer, we examined whether patient's working model of attachment anxiety/avoidance and perceptions of social support predicts adjustment to cancer.
Methods: All participants filled in a demographic questionnaire, the Relationship Scale Questionnaire (RSQ), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Mental Adjustment to Cancer (MAC).
Results: Anxious attachment predicted psychological adjustment: patients with high levels of anxious attachment showed high levels of helplessness/hopelessness and anxious preoccupation (p<0.01, and p<0.05, respectively). With regard to the function of perceived social support, the patient's perception of social support from friends was predictive of both fighting spirit and stoic acceptance (p = 0.01, and p < 0.001, respectively). Conversely, the patient's perception of support from family members was not predictive of adjustment to cancer. Patients in the advanced stages of the illness showed higher levels of helplessness/hopelessness (p < 0.05).
Conclusions: Anxious attachment and perceived social support predicted different domains of psychological adjustment to cancer. Perceived support from friends may predict the patient's tendency to consider cancer as a challenge and to take an active role in therapy and recovery, whereas social support from family was not predictive of various states of adjustment to cancer
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
La percezione del supporto sociale ed emotivo nel processo di adattamento alla malattia: uno studio con pazienti oncologici e loro caregivers.
No full textPurpose: this study aims to investigate the role of social and emotional support in predicting patient adjustment to cancer.
Patients and method: 80 patients with I stage cancer (mean age: 56,02) and their respective caregivers (mean age: 46,4) are included in the study. Participants are recruited in an outpatient oncology clinic. Most of patients (71,2%) have a breast cancer, and are treated with conservative surgery and mastectomy. Most of caregivers (78,7%) belong to patients’ family.
Results and discussion: patients’ perception of social support from friends and emotional support given to caregivers predict a better adjustment to cancer, reducing negative feelings and a resigned attitude towards the illness. Interestingly, a low sense of Helplessness and Fatalism are predicted by patients’ perception of receiving support outside their family, and giving emotional support to their caregivers within the family
