Qualità’ del lavoro e digitalizzazione. Riflessioni aperte sul caso italiano
No full textLa presentazione illustra le caratteristiche peculiari dell'Indagine Inapp sulla qualità del lavoro, con particolare attenzione al framework teorico adottato e alle cinque dimensioni di analisi contemplate. L’indagine consente di monitorare e valutare la qualità del lavoro sia dei lavoratori dipendenti che degli autonomi, di rilevare le tendenze e i cambiamenti in atto nel mercato del lavoro e contribuisce allo sviluppo delle politiche sulle questioni che riguardano la qualità del lavoro e l’occupazione.

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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Experimental tests on post-tensioned rocking concrete walls with end columns and steel dissipative devices
No full textIn many countries, the current seismic design practice for concrete structures is based on the exploitation of the ductility
capacity of some structural elements, such as beams in frame structures. This approach, even if theoretically able to
guarantee life safety for the occupants of buildings, has recently been criticized because it might lead to extensive damage
in structural elements. Damage that in many cases cannot be repaired. Therefore, this design practice might lead to limited
resilience; as highlighted by many recent earthquakes (e.g. Christchurch earthquakes) the recovery process after strong
seismic events may take years and have significant social and economic negative consequences. For these reasons
different structural systems and technical solutions have been developed in the literature in order to limit structural
damage, i.e. base isolation, viscous dampers, etc. Some of these technologies are very effective but might be unpractical
for some types of buildings, such as precast concrete structures, in particular for economic constrains. For these buildings
researchers have proposed specific solutions based on post-tensioned concrete elements free to rock at their base, with
easy-to-replace external dissipative devices. These systems aim at solving the limitations of ductility-based design though
self-cantering capabilities and easy reparability.
The present paper presents the results of an experimental campaign aimed at studying the behaviour under cyclic
horizontal loads of post-tensioned rocking concrete walls with end-columns and steel dissipative devices. The structural
system tested comprises a concrete wall with two bundles of post-tensioning cables, two post-tensioned concrete endcolumns
(one at each end of the wall) connected by beams and hysteretic dissipaters between the wall and each column.
Columns are used in order to support beams because, even if base rocking occurs, their uplift is limited given their small
cross section size. The paper discusses the quasi-static cyclic behaviour of two of these systems featuring different details
at the wall-base. Furthermore, it compares the experimental results with the predictions of design-oriented analytical
models
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
