    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

    Nursing Activity Score for estimating nursing care need in intensive care units: findings from a face and content validity study

    AimTo re-evaluate the face and content validity of the Nursing Activity Score currently adopted in evaluating activities that best describe workloads in intensive care units and their weight in describing average nursing time consumption. BackgroundThe Nursing Activity Score calculates the amount of nursing time that each patient will require over the next 24hours. It has been widely used around the world since its first validation in 2003. However, no re-evaluation of its validity with regard to the advancements achieved in intensive care units nursing care has been documented to date. MethodA research project was undertaken from 2012 to 2015, aimed at critically evaluating and validating this tool in the current context of Italian intensive care units nursing care. The 23 items were translated forward and backward into the Italian language, then a panel of 10 experts in critical care evaluated the face validity. Content validity was evaluated through focus groups involving seven critical care expert registered nurses. FindingsThe Nursing Activity Score instrument has been considered as not fully adequate to measure current intensive care units nursing activities and their weightings have been considered not fully adequate to score average nursing time consumption. From the content validity process, lack of adequacy has emerged with respect to the concept of nursing care underpinning the tool, the interventions included, its capability to predict the nursing resources needed, advancements achieved in intensive care units nurses' roles and competences, and the contextual factors that may influence consumption of nursing time. ConclusionsDevelopment of the Nursing Activity Score tool both conceptually and in its structure, in view of the innovations that have occurred in the context of intensive care units, is necessary to continue to have a common tool to help clinicians and managers to capture accurately and compare nursing care required by patients in critical care settings. Implications for nursing managementThere is a need to revise the Nursing Activity Score tool, enabling its use in estimating nursing workloads in current Italian intensive care units practice. A taskforce of clinical nurses and nursing managers, capable of protecting the valuable original Nursing Activity Score project and to advance its further development is recommended
