Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Frauds in scientific research and how to possibly overcome them
Get PDFFrauds and misconduct have been common in the history of science. Recent events connected to the COVID-19 pandemic have highlighted how the risks and consequences of this are no longer acceptable. Two papers, addressing the treatment of COVID-19, have been published in two of the most prestigious medical journals; the authors declared to have analysed electronic health records from a private corporation, which apparently collected data of tens of thousands of patients, coming from hundreds of hospitals. Both papers have been retracted a few weeks later. When such events happen, the confidence of the population in scientific research is likely to be weakened. This paper highlights how the current system endangers the reliability of scientific research, and the very foundations of the trust system on which modern healthcare is based. Having shed light on the dangers of a system without appropriate monitoring, the proposed analysis suggests to strengthen the existing journal policies and improve the research process using new technologies supporting control activities by public authorities. Among these solutions, we mention the promising aspects of the blockchain technology which seems a promising solution to avoid the repetition of the mistakes linked to the recent and past history of research
[Residency in hygiene and preventive medicine: present and future]
No full textINTRODUCTION: The changing needs and expectations of the population and the current financial distress lead the Italian health care system to face a profound challenge that requires also a new evaluation of professionals' training. Specialists in Hygiene and Preventive Medicine (HPM) are called for to develop new knowledge and skills in hygiene, public health, and management, as they fulfill leadership roles within the hospitals.
OBJECTIVE:
To investigate the current status of Hospital Health Management Boards (HHMB) and the specific know-how they require, in order to develop an adequate post-graduate residency training in HPM.
MATERIALS AND METHODS:
We conducted a literature review on the main and «gray literature» databases; then, we conducted three semi-structured interviews with the Chiefs of the HHMB operating in the major hospitals of Bologna (Northern Italy); lastly, we organised a workshop with residents in HPM and health workers of Emilia-Romagna hospitals.
RESULTS:
Interviews with Hospital Health Managers have highlighted the main issues faced by a modern HHMB. The main questions discussed were: the changing role of the hospital and its relationship with primary care; the increasing competition among professionals with different specialisations within the HHMB; the need to develop multi-professional teams; the necessity to enlarge HPM residency training programmes in order to meet the HHMB needs.
CONCLUSION:
The evolution of the HHMB reflects the evolution of the Italian health care system. HHMBs should better fit the organization to the context, and the post-graduate schools in HPM should follow this process. In the framework of the current rules and laws it is possible to focus for implementing training programmes that include management, coordination and negotiation skills, and help build an adequate leadership profile
