Caregivers e disabili nel labirinto della stratificazione regolativa
No full textIl contributo, nella prima parte, offre un tentativo di definizione
del caregiver secondo le fonti europee, internazionali e nazionali.
Successivamente si sofferma sui singoli istituti predisposti
dal legislatore a tutela e supporto del caregiver (congedi, permessi
e limiti del potere datoriale), secondo le attuali interpretazioni
giurisprudenziali. Si mettono infine in luce quelli che appaiono
i principali problemi della materia e che non sembrano in
via di risoluzione neanche alla luce delle più attuali disposizioni
normative

Lavoro e ambiente nell’Antropocene: il problema e il sistema. Presentazione [Work and environment in Anthropocene era. The problem and the system]
No full textThe authors present the issue (Work and Environment in Anthropocene Era) explaining the choice of the topic and the nowadays need to investigate connections and conflicts between work and environment. In this number, real cases of crisis and the representation of the large system are protagonists, reflecting on possible common itineraries of better preservation of both
Copper Toxicity in Maize: The Severity of the Stress is Reduced Depending on the Applied Fe-Chelating Agent
Full text linkThe wide use of copper (Cu)-based fungicide has caused a stepwise accumulation of Cu in the environment increasing the occurrence of phytotoxicity in crops. To understand and alleviate this abiotic stress, maize seedlings were grown in hydroponic solution with different combinations of Cu and iron (Fe) forms. Results showed that maize Cu sensitivity is related to the nature of the form supplied and to the chelate-exchange processes that might involve other elements, such as Fe. The use of CuSO4 excess (100 μM) caused severe reduction of plant growth, over accumulation of Cu, high activity of antioxidant enzymes, and impairment of the acquisition of other nutrients. In presence of chelating agents (citrate and ethylenediaminetetraacetic acid, EDTA) the ability of plants to tolerate high Cu-levels depends on the Fe nutritional status. Copper phytotoxicity symptoms do not occur when Cu was supplied chelated by EDTA. The use of synthetic agent EDTA (as Cu-EDTA and Fe-EDTA) prevented the accumulation of toxic Cu-level in plants and allowed a better homeostasis among nutrients. In presence of citrate, high concentration of Cu occurred in plants but its phytotoxicity was limited when even EDTA was available in solution. Results suggest that maize plants can operate a good control of nutritional status when Cu-excess is present concomitantly with a synthetic chelator (as EDTA) even when supplied as a Fe-fertilizer. These results pave the way to provide guidelines for the fertilization managements on Cu-contaminated soils to alleviate phytotoxicity in crops
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
