Movimenti di felicità. Storie, strutture e figure del desiderio
Un folto gruppo di autrici e studiose indaga la letteratura, il cinema, la filosofia con occhio attento a smascherare le trappole del lieto fine disseminate nel canone occidentale e il suo progetto di felicità per le donne, di contro invece a vite e opere femminili che hanno coltivato e coltivano altri progetti di libertà
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Dispelling the Myths Behind First-author Citation Counts
We 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Preoperative Planning for Primary Total Knee Arthroplasty (Mechanical, Anatomic, and Kinematic Alignment)
Proper knee alignment and soft tissue envelope integrity have been considered to be influential factors in determining the long-term outcomes and implant survival after total knee arthroplasty (TKA) [1]. Nowadays, several alignment options have been introduced in knee arthroplasty. Among them, the reference ones are mechanical alignment, anatomical alignment, and kinematic alignment [2]. In addition, the concept of hybrid alignment was recently introduced with the aim of optimizing the advantages of different types of alignment [2, 3]. Regardless of the choice of alignment, every patient requires a careful clinical and radiological assessment before knee replacement surgery; this preliminary study allows us to investigate the different characteristics and deformities presented by each patient and to be prepared for intra-operative challenges [4].
The preoperative clinical evaluation aims to analyze and quantify several parameters, such as ligamentous laxity, flexion contracture, deformity reducibility, and preoperative range of motion (ROM).
The evaluation of the ligamentous laxity guides the surgeon in the choice of appropriate implant constraint [5]. For example, a valid posterior cruciate ligament will allow the implant of a cruciate retaining arthroplasty. Large varus or valgus deformities can lead to collateral ligamentous contractures on the concave side and laxity on the convex side; therefore, performing a varus–valgus stress test at 0° and 30° of knee flexion can guide the choice of implant constraint [6–8]. Flexion contractures ranging from 5° up to 20–30° can occur in case of severe osteoarthritis; these cases require precautions to be taken into account before surgery: to achieve full extension it will be necessary to plan for a larger distal femur cut. Deformity reducibility predicts the need to perform ligament release in order to obtain balanced gaps [9]. No less important is the assessment of preoperative ROM; the literature shows how this correlates with postoperative ROM [10]. Therefore, the patient should be warned about the difficulty of obtaining a full ROM in case of limited preoperative ROM. This limitation is, in fact, partly due to inveterate contracture of the extensor apparatus and joint capsule, which can only be partially corrected during surgery
Migration of the femoral component and clinical outcomes after total knee replacement: a narrative review
Loosening is considered as a main cause of implant failure in total knee replacement (TKR). Among the predictive signs of
loosening, migration is the most investigated quantitative parameter. Several studies focused on the migration of the tibial
component in TKR, while no reviews have been focused on the migration of the femoral component and its infuence on
patients’ clinical outcomes. The aim of this narrative review was (1) to provide information about of the infuence of migration in femoral component of TKR prostheses, (2) to assess how migration may afect patient clinical outcomes and (3) to
present alternative solution to the standard cobalt-chrome prostheses. A database search was performed on PubMed Central®
according to the PRISMA guidelines for studies about Cobalt-Chrome femoral component migration in people that underwent primary TKR published until May 2020. Overall, 18 articles matched the selection criteria and were included in the
study. Few studies investigated the femoral component through the migration, and no clear migration causes emerged. The
Roentgen Stereophotogrammetric Analysis has been mostly used to assess the migration for prognostic predictions. An annual
migration of 0.10 mm seems compatible with good long-term performance and good clinical and functional outcomes. An
alternative solution to cobalt-chrome prostheses is represented by femoral component in PEEK material, although no clinical evaluations have been carried out on humans yet. Further studies are needed to investigate the migration of the femoral
component in relation to clinical outcomes and material used
