Metodi di filtraggio e classificazione di nuvole di punti per l’identificazione di strutture arboree
Full text linkPer descrivere le caratteristiche dendrologiche ed ecologiche di una qualsiasi area boscata si procede normalmente con l’analisi in sito di tutte le piante presenti. Il rilievo prevede l’impiego di personale tecnico in campo,comportando inevitabilmente un dispendio elevato di tempo e di personale. Il presente lavoro, nato in collaborazione con ARPA Valle d’Aosta, ha lo scopo di proporre una metodologia di analisi robusta e automatizzata che, partendo da un modello tridimensionale di una qualsiasi area boscata costituito da una nuvola di punti, consenta di estrapolare in via analitica alcuni di questi parametri (in particolare numero, posizione degli alberi e diametro dei tronchi ad altezza petto).L’algoritmo proposto si basa sull’individuazione dei tronchi in quanto elementi geometrici particolarmente distinguibilie si propone come strumento per supportare e rendere più rapide le fasi di misurazione di tali valori
Una vita al lavoro: trasformazioni del welfare e pratiche di Commonfare (Welfare del Comune)
No full textThe transformations of the processes of valorisation that have innervated the passage from Fordist-Taylorist to bio-cognitive capitalism have also highlighted the transformations of the welfare system. In this essay, we intend to analyse the process according to which welfare institutions have been transformed into productive factors, capable of influencing the mechanism of capitalist valorisation. Starting from what emerged in the field survey conducted in three pilot countries (Italy, Holland, Croatia) from the Horizon 2020 research "Pie News", we can observe that there are attempts to bottom-up experiments within the social body, thanks to which it is possible to resist the growing uncertainty and economic insecurity generated by the new models of neo-liberal governance (Butler, 2015, Leroy, 2015). From this point of view, the theme of the centrality of social reproduction and care expropriated by contemporary production paradigms is addressed. Far from being a simple cost, the reproduction and enhancement of the living being is becoming, thanks also to the development of private forms of health and social insurance, more and more directly or indirectly productive. In this context, the final paragraph is dedicated to the presentation of the Commonfare proposal (Welfare of the Common), originating from the analysis of good welfare practices from below
Anthropomorphic Capital and Commonwealth Value
No full textIn this essay, we intend to analyze the process of accumulation of contemporary capitalism, in which the regime of valorization derive from the notion of “common” a “results of social production that are necessary for social interaction and further production, such as knowledges, languages, information affect, and so forth” (Hardt and Negri, 2009) and from its expropriation. When we deal with the concept of “common,” the reference is made to a heterogeneous category. In this text we refer to two modalities of expression of the “common:” the digital common (section network value) and the common of social reproduction (section social reproduction value or the economy of the interiority and anthropomorphic capital). Regarding the first case study, the concept of “network value” is investigated and defined as a product of individual life in a relational context increasingly controlled and subsumed by the social media and big data industry. Regarding the second, we discuss how the activity of social reproduction of individuals is today central in the process of accumulation of the economy. “Social reproduction” is a useful concept to investigate what we call the “anthropomorphic capital,” that is the capacity by the contemporary labor organizations to capture and make productive the essence of today's life and its complexity. In short, it transpires better and better how all activities are productive, i.e., accumulation generators. We observe the apparent paradox of a generalization of surplus value in the era of the decline of waged employment and with it a tension of capital contemporary to the general mortification of living labor. In fact, we note how capital claims to transform the human being into capital itself, explicitly assuming the whole of human existence as a field from which accumulation can be generated (human being, enterprise or human capital). This is what, at this point, we call anthropomorphic capital or the economy of interiority. In the last section, we report some results of an empirical research “Commonfare-Pie News,” able to underline how life is more and more subsumed to the logic of capitalistic valorization, to the point that today we can speak not only of the subsumption of labor to capital but of a real life subsumption
Life put to work: towards a theory of life-value
No full textStarting from the recognition that only a "labour theory of value" is able to provide a measure of the value of the surplus, in this essay we’d like to pose the question of how the labour theory of value must dynamically adjust to the capitalist system and the succession of different modes of accumulation. Specifically, we focus on structural changes that have invested and partially modified the process of enhancing the transition from industrial-Fordist to “bio-capitalism”, at least in that area of the world where this transformation has established itself and is present. It is in this passage that the labour theory of value - intended primarily as a theory of value-time work - requires a redefinition that is able to grasp the qualitative changes that have overtaken to undermine the traditional theory of value labour. More in particular, it will be considered a specific form of value creation: the one linked to the concept of affective labour. Finally, in the last and final section, we discuss the hypothesis of the theory of life-value, nodding briefly to the theoretical problems relating thereto, in view of a future research agenda
Segmentation du travail cognitif et individualisation du salaire
No full textThe paper deals with the transformation of labour and wages differentiation, providing some empirical examples in the diffusion of cognitive labour, especially in the publishing industry. The first part gives a definition of cognitive labour by focussing on the role played by relation activities and learning processes. It is the type of labour which is able, better than others, to exploit the new types of dynamic economies of scale which affect the accumulation of cognitive capitalism. Network and learning activities, by definition, lead to an increase of labour and wage individualisation and fragmentation, which in many cases imply a precarious condition in terms of income and social security. In the second part of the paper, the labour organisation is analysed in the publishing industry. In the publishing industry, cognitive labour is increasing as a consequence of the introduction of ICT. Empirical data show that this dynamic leads to an increase of wages differentiation and precariousness, more and more based on the new cognitive division of labour
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
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
