Impact of the COVID-19 pandemic on voluntary terminations of pregnancy in an Italian metropolitan area
No full textPurpose: The COVID-19 pandemic and national lockdown from 9 March to 4 May 2020 changed social, familial, and sexual relationships, as well as how citizens interact with the health services. How these profound changes have affected sexuality, contraception and voluntary terminations of pregnancy is still largely undescribed. The main objective of this study was therefore to find out whether the COVID-19 pandemic and ensuing lockdown affected the demand for legal abortion. Material and methods: The study period was divided into three phases: the pre-pandemic (January and February 2020); lockdown (March and April); and post-lockdown (May and June). The number and characteristics of women requesting pregnancy termination each month during that time were compared with the stats for the same months in the preceding three years (2017–2019). Results: Immediately after national lockdown, the number of voluntary abortions markedly declined (-40.45%). The effect was more evident in women below 20 years of age (-66.67%), employed versus unemployed women (-42.71% vs. −21.05), and non-Italian versus Italian citizens (-53.01 vs. −32.85). No difference was found in the mean time from request to execution of the procedure, or in the type of the procedure used. Conclusion(s): National lockdown reduced the number of unwanted pregnancies, especially in younger women. The Italian health service’s response to the demand appears to have been unaffected by the pandemic. However, as the demand for abortion is still high, probably due to unplanned pregnancies among cohabitants within a stable relationship, contraception guidance should be improved among women traditionally deemed low-risk in terms of sexual behaviour
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Ultrasound-guided transvaginal radiofrequency ablation of uterine fibroids assisted by virtual needle tracking system : a preliminary study
No full textPurpose: The purpose of this study was to assess the feasibility and outcome of transvaginal ultrasound (US)-guided radiofrequency ablation of uterine fibroids assisted by a real-time virtual needle tracking (VT) system. Methods: Between January 2017 and February 2018, 19 patients (age 45 ± 8 y, range 36–53 y) with 25 symptomatic uterine fibroids underwent transvaginal radiofrequency ablation (RFA) at a single center. Mean number of fibroids for patient was 1.7 (min, max: 1–3). Patients with more than one fibroid were 10 (52.6%). Uterine fibroids (mean volume: 13.6 mL; range: 5.3–41.9 mL) were treated with a dedicated internally cooled 17 G 35 cm RF needle with 1 cm or variable active tip and the moving shot technique. An electromagnetic system was used for showing a virtual needle during the procedure. Contrast-enhanced ultrasound evaluation was performed before and immediately at the end of procedure. Feasibility of the procedure, technical success rate, volume percentage reduction at 1, 3 and 6 months, clinical outcome (QOL score) and complications were analyzed. Results: Procedure was feasible in 19/19 patients (100%). Technical success was achieved in 100% of 25 treated fibroids. Mean fibroids volume decreased from 13.6 ml at baseline to 5.9 ml at 6 month (reduction rate 62.7%, range 48.5–76.9; p <.05). No major immediate or late complications occurred. Minor complications occurred in two patients. QOL score significantly improved from 68 ± 36 at baseline to 97 ± 16 at six-months follow-up (p <.05). Conclusion: Transvaginal US-guided RFA assisted by a real-time VT system is a feasible, safe and effective technique for the treatment of uterine fibroids
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Letter from R. R. Zellick, Assistant Trust Officer, Anglo California National Bank of San Francisco, to Joseph R. Goodman, October 2, 1942
No full textLetter from R. R. Zellick, Assistant Trust Officer at The Anglo California National Bank of San Francisco, to Joseph R. Goodman, regarding property owned by Dave Tatsuno. Zellick mentions a dispute between current tenants and Tatsuno, and that Tatsuno has asked Goodman to help locate trustworthy tenants.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
