The Enforcement of External Voting Rights and the Italian Diaspora: The Case of the United States
Full text linkThis essay examines the voting behaviour of Italian citizens in the United States in the homeland’s Parliamentary elections and referenda since the passing of a 2001 legislative package that let Italian nationals residing abroad vote by mail. Specifically, it aims at assessing to what a degree external voting rights strengthened Italian Americans’ diasporic ties to Italy. The essay concludes that most eligible voters failed to profit by such provisions and that the mobilization of the few who mailed their ballots resulted less from Italian-based concerns than from U.S.-oriented stimuli. Therefore, Italian citizens hardly revealed a disporic behaviour in politics
Iatrogenic Trapped Penis in Adults: New, Simple 2-Stage Repair
No full textPurpose: We present a new, 2-stage functional and cosmetic reconstruction of concealed penis in adults with short-term subjective outcomes.
Materials and Methods: Patients with excess penile skin removal, shaft tissue scarring and penile retraction with poor functional and cosmetic results underwent 2-stage repair. At stage 1 after a coronal incision and penile degloving an intrascrotal tunnel was formed and the penis was transposed through the scrotum.
Three or 4 zero or 2-zero nonresorbable sutures were applied ventral to the penis, crossing through the entire scrotum to ensure complete scrotal skin adhesion to the penis (penile scrotalization). At stage 2 after 6 to 12 weeks the scrotal
skin at the penile base was incised bilaterally to separate the skin around the penis from the remaining scrotal skin (penile descrotalization). Evaluation was scheduled 3, 6 and 9 months postoperatively, and annually thereafter.
Results: Ten men with concealed penis underwent this 2-stage penile repair, including 8 who were circumcised and 2 who underwent conservative surgery for penile cancer. Mean SD operative time was 75 15 minutes for stage 1 and 45
10 minutes for stage 2. No major intraoperative or perioperative complications occurred except superficial scrotal hematoma in 1 patient. At a median followup of 20 months (range 6 to 72) all men were in satisfactory clinical condition and the median patient satisfaction visual analog score was 97 (range 85 to 100). All
patients recovered normal spontaneous erection with regular sexual intercourse 4 to 8 weeks after operation 2.
Conclusions: This simple, new 2-stage technique seems feasible and effective, and it is well accepted by patients. Further studies are mandatory to confirm preliminary result
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
PENILE RESCULPTURING IN SURGERY OF M. PEYRONIE: RESTORATION OF PENILE LENGTH, GIRTH AND SHAPE WITH OR WITHOUT PENILE PROSTHESIS IMPLANTATION
No full textDispelling 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
Correlation Between Primary Hypospadias Repair and Subsequent Urethral Strictures in a Series of 408 Adult Patients
No full textBackground The correlation between primary hypospadias repair and subsequent urethral strictures in adults has never been addressed. Objective: To evaluate the correlation between the site of primary hypospadias repair and the site of subsequent strictures and to investigate the predictive factors of failure after urethroplasty. Design, setting, and participants An observational, retrospective, descriptive study of adult patients with urethral strictures following hypospadias surgery was carried out in a single centre. Intervention Meatotomy, meatoplasty, end-to-end anastomosis, urethroplasty, perineostomy, urethrotomy, and fistula closure. Outcome measurements and statistical analysis We performed correlations between the site of primary hypospadias and the site of subsequent strictures, treatment failure, and patient lack of motivation for definitive treatment. Cross-tables, Kaplan-Meier curves, and logistic or Cox regression were used. Results and limitations A total of 408 patients, with median follow-up of 96 mo, were included. Concordance between the site of primary hypospadias repair and the site of subsequent strictures was observed. Multivariable analysis revealed that the number of previous operations needed for initial hypospadias repair was not associated with the risk of treatment failure (hazard ratio [HR] 0.96; 95% confidence Interval [CI] 0.88â1.04; p = 0.3) or a lack of patient motivation (odds ratio 0.99, 95% CI 0.90â1.10; p = 0.9). Length of stenosis (HR 1.38, 95% CI 1.11â1.71; p = 0.004) and lichen sclerosus (HR 1.73, 95% CI 1.03â3.25; p = 0.035) were associated with a higher risk of treatment failure. Our study is not representative of the entire population of patients with hypospadias repair. Conclusions The stricture site is usually consistent with the site of hypospadias. Stricture length, but not the number of previous operations needed for primary hypospadias repair, was associated with the risk of failure. Patient summary The number of operations needed for hypospadias repair was not associated with failure of subsequent urethroplasty. Our findings show that the number of previous operations needed for hypospadias repair was not associated with the risk of treatment failure for subsequent strictures
