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
The Italian version of the pathological narcissism inventory: Factor structure and psychometric properties
No full textObjective
The Pathological Narcissism Inventory (PNI; Pincus et al., 2009) is a multidimensional measure of
pathological narcissism. The PNI assesses seven dimensions that capture both overt and covert
expressions of narcissistic grandiosity and narcissistic vulnerability (Pincus et al., 2009; Wright et al.,
2010; You et al., 2013). Narcissistic grandiosity is measured by the dimensions of grandiose fantasy,
self-sacrificing self-enhancement, and exploitative relationship; whereas narcissistic vulnerability is
measured by the dimensions of contingent self-esteem, entitlement rage, devaluing, and hiding the self
(Wright et al., 2010). The aim of the present study was to investigate the factor structure of the PNI
among an Italian non clinical sample.
Methods
The PNI was administered to 753 participants (444 female, 309 males) with a mean age of 27.49 (SD=
7.73). Statistical analyses were performed using R 3.1.0 (lavaan and psy packages).
Results
Confirmatory factor analyses with the item parcels confirmed the 7 first-order factors (χ2SB(147)=
382.091; p= .000; RMSEA= .046; 90% confidence interval [CI] on RMSEA= 0.041 - 0.051; CFI= .963;
NNFI= 0.949) and the 2 second-order factors of the PNI (χ2SB(160)= 498.506; p= .000; RMSEA= .053;
90% confidence interval [CI] on RMSEA= 0.048 - 0.058; CFI= .947; NNFI= 0.934). Standardized factor
loadings of the PNI item parcels ranged from .675 to .895. The latent factor intercorrelations ranged from
.07 to .83. Finally, alphas for all scales ranged from .70 to .93 (total PNI α= .93).
Conclusion
Results confirmed the multidimensional structure of the PNI (Pincus et al., 2009; Wright et al., 2010; You
et al., 2013), showing good psychometric properties. These preliminary findings suggest that the Italian
version of the PNI may be well suited for the assessment of pathological narcissism
Difficulties in emotion regulation among inpatients with substance use disorders: The mediating effect of mature defenses mechanisms
No full textObjective: Although the relationship between Substance Use Disorders (SUDs) and emotion regulation is a topic of great scientific interest, little is still known about the nature of this association. The aim of the present study is to clarify which specific difficulties in emotion regulation describe SUD inpatients, studying whether this relationship is mediated by the use of defense mechanisms. Method: Difficulties in emotion regulation and defense mechanisms were evaluated in 58 SUDs inpatients and 73 community participants. Results: Results showed that SUDs are associated with limited access to emotion regulation strategies when negative emotions are experienced. This relationship between difficulty in accessing emotion regulation strategies and the presence of SUDs was mediated by mature defenses. The more difficulties in accessing such strategies were, the less mature defenses were used; the less mature defenses were used, the more likely the presence of SUDs was. Conclusions: These findings suggest the importance of considering mature defense mechanisms in understanding difficulties in emotion regulation among SUD inpatients. Research and Clinical implications are discussed
Personality Disorders (DSM-III-R DSM-IV): Prevalence in alcoholics and influence on drop out from treatment
No full textMany questions remain with regard to the relationship between DSM personality disorders (PDs) and substance abuse and dependence as to the potential influence of PDs on treatment outcome. In this study we first examined the prevalence of PDs in a sample of 123 hospitalized alcoholics, using PDQ-R, a self-report questionnaire for Axis II diagnoses. We found a significant prevalence of Cluster B PDs. For a better understanding of the topic, in the second part of our study, we used SCID-II, a semistructured interview according to DSM-IV. With these new data, we investigated the association between PDs and drop out from treatment in a sample of 25 alcoholics. We present some preliminary data which seem to confirm the precious results of the high prevalence of Cluster B PDs in alcoholics and a significant correlation between Cluster B PDs and drop out
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
