    Osservazioni su alcune incertezze e incongruenze nella terminologia dendrometrica

    Considerations on uncertainties and inconsistencies in the dendrometric terminology. In the italian forestry literature, the adjective “cormometric” combined with the noun volume or its equivalent, is used with three different meanings which are respectively linked to the stem, to the trunk or large timber. To find the origins and also the reasons for these different meanings of the term, we need to go back in history. The first definition is by Alfonso Di Berenger first director of the Vallombrosa Forest, the first seat of higher Forestry education in Italy between 1869 and 1951. He defined cormometric the volume of the “legname sociale” (industrial timber), or the trunk. Follows the definition of Vittorio Perona that, in the wake of the German concept of Derbholz, considers cormometric volume as including also portions of branches above seven centimeters. Giuseppe Di Tella, Professor of forest mensurations and forest management in Florence between 1916 and 1937 is the author of a large general volume table for fir where the cormometric volume is defined as the “stem including the top”, but also, following the doctrine, as a measure expressing the volume of the part of the stem that can provide wood for building or industry. Subsequently, with the definitions of the Professors Generoso Patrone and Guglielmo Giordano confirming the doctrinal meaning of Di Tella, the sense of the term remains unchanged. In 1986 Hellrigl called cormometric mass, the aboveground woody tree mass limi - ted to trunk and limbs to be determined; however, this definition did not find any application. Alternative definitions by Roberto Del Favero and Orazio La Marca consider cormometric volume including top and cormometric volume excluding top. In the forest literature, instead, there were more changes in 2007, when the Forestry Research Portal published a notation regarding cubing of forest stands, stating “in the cubing of forest stands, woody volume estimated for conifers is, in general, cormometric (i.e., volume of the stem including bark)” which gave rise to the present note. Alongside, and again in connection with the meaning of the term cormometric, certain combinations of terminology reported in two multilingual glossaries of IUFRO are highlighted

    Foreste, Carbonio e Assestamento forestale. Alcune meditazioni in tema.

    No full text
    Vengono accostati concetti propri del bilancio del carbonio nel sistema foresta-legno e dell'assestamento forestale. In ottica comprensiva, vengono considerati tre diversi scenari forestali: la foresta vergine, la foresta assestata e la foresta in corso di assestamento. Tra le similitudini, si evidenziano particolarmente quelle tra gli stock di carbonio e di provvigione legnosa, tra i flussi di carbonio ed incremento e ripresa. Tra le differenze più evidenti, spicca la necessità di includere, nel bilancio del carbonio, il complesso terreno-necromassa-suolo. Un ruolo decisivo ai fini dell'utilità carbonico-atmosferica del sistema foresta-legno è rivestito inoltre, nel caso di foreste gestite, dallo stock dei prodotti legnosi nell'extrabosco. Si vuole sottolineare con ciò l'importanza della cultura assestamentale anche in una gestione forestale moderna, attenta a garantire le nuove utilità che via via si aggiungono ad ampliare la dimensione funzionale del bosco

    Legno da Energia. Prezzi indici in Austria e Italia

    No full text
    From the 1979 the Agriculture Chamber of Lower Austria (Niederösterreich) computes and publishes every three months an index about the energy wood price in Austria. From the 2001 also the Chamber of Commerce, Industry, Craft Trade and Agriculture of Bolzano publishes every month the price of different wood fuels. In the present paper the National Austrian index is analyzed and discussed according to its structures. Also wood fuels prices of both the area (Austria and Bolzano province in Italy) are compared

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We 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

    Pragmatic Case Studies as a Source of Unity in Applied Psychology

    No full text
    To unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We 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
