No full textAnxiety and information on heart surgery. A study [Ansia e informazione in cardiochirurgia, uno studio.]
No full textThe heart surgery represents a moment of high critical state for the patient. The association of the heart to the idea of the life, intensifies the emotional and psychological tensions, the worries for the family, for anaesthesia procedures and for the activities developed in the department of intensive therapy. The demand of the present study is born on the relationship among information related to the principal anxiety elements that the patient meets in intensive therapy and the reduction of anxiety in pre and post surgery. Purpose of this study is to measure the pre and post surgery anxiety among a group of patients that have received a structured information through a brochure on purpose studied and among a group of patients that have received not structured information. Results show a relationship between information and reduction of patient's heart surgery anxiety

Evaluation of data quality in lichen biomonitoring studies: the Italian experience.
No full textA total of 65 operators involved in lichen mapping studies in central and northwestern Italy underwent quality control tests during five lichen biomonitoring workshops organized between 1999 and 2000. The results showed that 75\% quantitative accuracy and 90\% quantitative precision can be regarded as satisfactory levels for lichen biodiversity data; 65\% proved to be sufficient for accuracy of taxonomic identification in the field. Average correct assignment of the interpretative naturality/alteration class was only 48.7\%. The results indicated the need for taxonomic training
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
