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
AMALPI trek: a geocultural trail from Maloja to St. Gotthard to increase the awareness of natural hazard in mountain settings
Full text linkThe AMALPI Trek takes its name from the A.M.AL.PI.18 Project [1], which is the Italian acronymous for “Moving Alps, and Movements in the Alps”, developed in the framework of the European funded Interreg Italy-Switzerland Cooperation Program V-A 2014-2020. The project aims to encourage an innovative strategy for the promotion of natural and cultural heritage in the Alpine area from Maloja to St. Gotthard (through Val Bregaglia, Valchiavenna, Regione Moesa and Alto Ticino), even by the creation of a cross-border geo-cultural trail connecting sites which have experienced important geomorphological and anthropic changes due to the occurrence of landslides of great social impact. The trail is addressed to a scientific-cultural and educational tourism, to raise the perception of landscape components in the framework of the “total history”, composed by the geo(morpho)logical, bioecological and historic-cultural heritages. Placed in a central position, the AMALPI Center (scheduled to open mid-2023 in Chiavenna), will be a study and research hub on large landslides, reference for school activities and promotion events. In addition, an open access hiking guidebook and map will lead the trekker to discover tools and methods that allow the comprehension of past and ongoing processes, with the help of illustrative panels describing the main patrimonial aspects of the territory, which is rich in historical palaces, archaeological sites, and natural monuments.
The AMALPI Trek runs through 10 Alpine valleys and crosses 7 mountain passes, for a total of about 150 km, plus several thematic itineraries that branch out of the main trail. Along the way, 19 large landslides of different age and type are touched. In many segments, the AMALPI trek follows historical trade routes, used in the past for the exchange of silk and soapstone products. There are some links between large landslides and stone resources typical of these mountains. A striking example are the “crotti”, natural caves used as cellars, perfect places for the storage of foods and other goods, and the “trone”, local soapstone caves, both generated by the gravitational accumulation of cyclopean boulders. The petrographic features of soapstone outcropping rock offer then a good workability, but locally they become weakness planes predisposing sliding.
Looking at the causes and effects of landslide events, the trekker accrues the perception of human vulnerability to natural hazard, but it is also invited to discover how to prevent, mitigate, and manage hillslope dynamic to develop a sustainable and fulfilling life in mountain areas.

Standards for pH measurements and first ionization constants of o-phthalic acid. Methylcellosolve-water solvent mixtures from -10 to 45°C

The corresponding values of the first ionization const. of o-phthalic acid (H2Ph, benzene-1,2-dicarboxylic acid), which is a key quantity for the acquisition of pHRVS stds., have been detd. from emf. measurements of the reversible cell Pt|H2|H2Ph + KHPh + KCl|AgCl|Ag|Pt
Gentilezza e galateo in RSA : La rivoluzione silenziosa
No full textIl volume che proponiamo può essere utile a studenti, familiari, ricercatori, professionisti della salute e a quanti ritengono che l'aver cura dei malati significhi soprattutto difenderne la dignità e la stima, riconoscerne l'umanità, oltre le maschere, talvolta incognite e normalizzanti, della patologia e della non autosufficienza. La gentilezza è il segno esteriore di una moralità profonda, di un desiderio sincero, che si esprime con atti visibili, di essere utili per alleviare la sofferenza dell'altro. Il desiderio di curare toglie di mezzo qualsiasi pretesa di risarcimento, concreto o psicologico. Inoltre, la gentilezza non è mai noiosa, ripetitiva, pesante, intrusiva, ma sempre lieve, pur senza perdere di concretezza e quindi di serietà e credibilità. Ma come costruire una RSA (ma anche un centro diurno, un servizio sociosanitario, un segretariato sociale) gentile? Può essere molto complesso, ma ci rendiamo presto conto che non vi sono altre vie se si vuole evitare l'aggressività senza dolcezza, che si autoriproduce e crea angoscia su angoscia. La silenziosa, gentile opera quotidiana di donne e uomini - che assistono i loro simili, meno fortunati - e la loro esemplare naturalezza rappresentano una vera rivoluzione culturale: la scelta della ragione dell'essere su quella dell'apparire. E quindi, come dice Marco Trabucchi nella sua prefazione, "onore a medici, infermieri, OSS, ASA, psicologi, fisioterapisti, educatori, terapisti occupazionali... a tutti coloro che si sentono rappresentati in questo volume sulla gentilezza"
