Current concepts in hip-spine relationships: making them practical for total hip arthroplasty
Full text linkHip, spine, and pelvis move in coordination with one another during activity, forming the lumbopelvic complex (LPC).These movements are characterized by the spinopelvic parameters sacral slope, pelvic tilt, and pelvic incidence, which define a patient's morphotype.LPC kinematics may be classified by various systems, the most comprehensive of which is the Bordeaux Classification.Hip-spine relationships in total hip arthroplasty (THA) may influence impingement, dislocation, and edge loading.Historical 'safe zones' may not apply to patients with impaired spinopelvic mobility; adjustment of cup inclination and version and stem version may be necessary to achieve functional orientation and avert complications.Stem design, bearing surface (including dual mobility), and head size are part of the armamentarium to treat abnormal hip-spine relationships.Special attention should be directed to patients with adult spine deformity or fused spine because they are at increased risk of complications after THA
Delivering orthopaedics in Burundi: a model for humanitarian surgery in resource-limited settings
Full text linkBurundi remains one of the most socioeconomically challenged countries globally, facing profound limitations in healthcare infrastructure, workforce, and access. In this context, the Italian Medical Foundation for Central Africa (FIMAC) has conducted humanitarian orthopaedic missions for over two decades in Bubanza, addressing critical musculoskeletal conditions in both paediatric and adult populations. This essay provides a comprehensive overview of the operational, clinical, and ethical dimensions of these missions. Commonly treated pathologies include chronic osteomyelitis, neglected fractures, open injuries, and congenital or acquired limb deformities—conditions frequently encountered in advanced stages due to delayed access to care. Resource-sensitive protocols guide interventions and rely heavily on collaboration with local healthcare workers, who receive targeted training in trauma management, postoperative care, and basic surgical techniques. The aim is not just to deliver urgent care but to foster sustainable improvements through capacity building and knowledge exchange. Major challenges include a lack of surgical infrastructure, limited availability of diagnostics and sterile equipment, as well as sociocultural barriers to care, such as language and traditional beliefs. Despite these constraints, the missions yield significant functional and psychosocial outcomes, particularly among paediatric patients. Ethical considerations, including informed consent, scope of practice, and cultural humility, are central to responsible practice in this setting. The personal and professional impact on participating surgeons is profound, often reshaping clinical priorities and reinforcing the humanistic foundations of the medical profession. The paper concludes by advocating for the establishment of permanent surgical facilities, structured deployments, and scalable innovations to enhance the continuity of care and address surgical inequities in low-resource settings
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
