Posture e imposture del lavoro cognitivo. Ripensare la pratica sindacale nel capitalismo delle reti e dei saperi
No full textLa centralità della componente cognitiva all’interno dei processi di produzione del valore contemporanei si accompagna a una progressiva frantumazione e umiliazione del lavoro. Appare inoltre piuttosto evidente come i caratteri oggettivi e soggettivi del lavoro cognitivo diano vita a fenomenologie culturali e sociali inedite, che le tradizionali coordinate teoriche interpretative della modernità industriale stentano a comprendere. Ad esempio, il rapporto tra lavoro e processi di soggettivazione tende oggi sempre di più a seguire percorsi “imprevisti” e non scontati, che da un lato re-inscrivono il lavorare all’interno d’inedite e singolari istanze di autonomia e cooperazione sociale, dall’altro lo “intrappolano” in nuove, diffuse e logoran-ti condizioni di sfruttamento. Il futuro del sindacato dipenderà, allora, anche dalla sua capaci-tà di interpretare e dare risposta alle nuove domande di tutela e progettualità sociale del lavo-ratore cognitivo
Incrinature. Posture e linee di fuga del lavoro cognitivo
No full textChe cosa rimane del lavoro nella società delle reti globali e dei processi di accumulazione basati sulla finanziarizzazione della vita? Cosa resta del lavoro nel momento in cui l’estrazione del valore nel capitalismo pare avere sempre meno a che fare con la quantità di lavoro impiegato nei processi di produzione? La questione è tanto spinosa quanto controversa e merita, da un lato, cautela analitica e, dall’altro, una buona dose di coraggio interpretativo. Il lavoro (o meglio la sua attuale scarsità sociale), non c’è dubbio, occupa con rinnovata e maniacale frequenza lo spazio circoscritto dai riflettori della discussione pubblica. La crisi economica globale morde così forte il lavoro, infatti, che finisce per smembrarlo e quindi per allentare la sua tradizionale capacità di istituire coordinate e norme per il riconoscimento e l’orientamento sociale. Questi sono i temi di fondo dell'articolo, temi che si tenta di analizzare e interpretare a partire da alcune importanti categorie deleuziane e foucaltiane
Formazione professionale ed esiti occupazionali: un modello di valutazione e un’applicazione al Veneto
No full textThe aim of the article is to analyze the occupational outcomes of the vocational education and training programs. The article proposes an evaluation framework which considers three main perspectives: the labour market (related to the “quality” of the occupation), the educa-tional system (related to the efficiency and the efficacy of the school-work transition proc-ess) and the individual (related to the perception of utility of the competencies learned at school and to the general level of satisfaction for the school experience). This model has been developed as a part of a national two years research project “Evaluation of the out-comes and of the impacts of the vocational education and training policies” funded by the Ministry of Labour and Welfare and coordinated by Ires. In the article, the main results re-ferred to Veneto region are presented
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
Possibilities and limitations of natural ventilation in restored industrial archaeology buildings with a double-skin facade in Mediterranean climates
No full textThere is an open discussion concerning how to improve energy performance of old dismissed industrial archaeology buildings and which could be the best choices for their sustainable re-use. In this work, a case study is analysed for investigating the possibility of application of passive solar systems in a Mediterranean climate on a dismissed silk factory, with particular reference to double-skin façade and natural ventilation, by means of dynamic simulations performed by coupling TRNSYS and LOOPDA simulation models. Natural ventilation in historical industrial buildings has been used in the past, by means of technical openings between floors and chimneys at the top. In this study the old airflow patterns are maintained and, due to the sunspace in winter and the night-cooling in summer, 12% of the energy might be saved in one year
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
