    Sentinel Lymph Node Biopsy in Breast Cancer

    No full text
    Since the first radical mastectomy proposed by William S Halsted in the 1890s, axillary lymph node dissection (ALND) has been considered the standard procedure for surgical treatment of breast cancer. Although the extent of surgery decreased, ALND was extensively performed for a century. ALN status is the most important prognostic factor for patients with breast cancer. However, although ALND is accurate in determining nodal status, this is at the expense of significant morbidity, both physical (pain, lymphedema, loss of strength) and psychological (worsening of body image). The concept of the “sentinel lymph node” (SLN) in breast cancer was introduced in the 1990s, following research on penile cancer and melanoma. The objective was to perform less invasive surgery in a targeted population, given the risk of postoperative complications and discomfort experienced after ALND.

    Il volume offre una visione d’insieme dello sviluppo delle arti in Cina a partire dal periodo Neolitico fino alla dinastia Qing (1644-1911) attraverso una articolazione in dieci capitoli e corredato da un ricco apparato iconografico, cronologia dettagliata e bibliografia ragionata. E’ rivolto sia ad un pubblico generico come agli specialisti del settore, ed è stato pensato in particolare per gli studenti universitari, che possono utilizzarlo coma manuale di base per una introduzione all’arte cinese. This fully illustrated book presents a complete overview of the developments of the arts in China from the Neolithic period to the Qing dynasty (1644-1911). It is divided in ten chapters followed by a detailed chronological chart and an annotated bibliography. Aimed at the general reader as well as the specialists, this book is especially directed to Italian university students who can use it as a manual to gain a fundamental understanding of the main historic developments in Chinese art

    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

    Full text link
    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
