Danni da vento in Val Visdende (Comelico, BL). Analisi di alcune aree colpite a pochi anni dall'evento.
No full textNegli ultimi anni in Valvisdende (Comelico, BL) si sono presentati numerosi danni da vento, soprattutto in occasione di fenomeni meteorologici importanti nella stagione estiva. L'impatto di questi disturbi va considerato anche tenendo conto dell'importanza economica e sociale delle foreste locali e della rilevanza naturalistica del luogo, classificato area SIC.
Lo studio considera tre aree pesantemente danneggiate dal vento nel corso dell'ultimo decennio. Vengono esaminate le condizioni strutturali e di composizione del popolamento circostante l'area schiantata, le caratteristiche morfologiche delle piante superstiti, la eventuale presenza di rinnovazione e le variazioni avvenute nella composizione floristica in seguito al disturbo
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

In a specific mole ratio, these monomers establish both intra- and intermolecular associations that can affect their behavior in aqueous solution. These custom-made polymers, find applications in various stages of crude oil production, particularly in enhanced oil recovery. This study aims to modify a copolymer of acrylamide and acrylic acid through amidation of between the carboxylic acid of the copolymer with primary amine of a dendronized aminotriester (Behera’s amine) to obtain a copolymer with enhanced viscosifying properties in aqueous solution. Spectroscopic methods such as Fourier Transform Infrared Spectroscopy (FTIR), 1H and 13C NMR were employed to confirm the incorporation of the dendron in the copolymer chain. Size exclusion chromatography–multi-angle light scattering–differential refractometer index detectors (SEC-MALS-dRI) and dynamic light scattering (DLS) were employed to determine the weight-average molar mass, dispersity, and radius of gyration and hydrodynamic radii of the polymer in solution, respectively. Additionally, the viscosity and viscoelastic parameters of the new copolymers in aqueous solution were evaluated by rheometry. The results demonstrate that the incorporation of Behera’s amine through amidation leads to an increase in viscosity by at least 2.2 times compared to the unmodified acrylamide–acrylic acid copolymer.info:eu-repo/semantics/publishedVersionFil: Meleán Brito, Ramses S.

Valuing landslide risk reduction programs in the Italian Alps: The effect of visual information on preference stability
No full textWe use discrete choice experiments to investigate the social demand for landslide protection projects. Given the importance of information in public good valuation via surveys, we explore the effect of specific visual information on the stability of preference estimates
Ecosystem services’ values and improved revenue collection for regional protected areas
No full textThe management of conservation areas is a costly enterprise, especially vulnerable to budget cutting when austerity measures are being considered. Optimal spatial taxation dictates that tax-payers contribute proportionally to the benefits they receive. This paper provides a framework to derive spatially varied benefit estimates for ecosystem services produced in Natura 2000 protected areas of Lombardy (Italy). These may be used as a framework for spatially optimised taxation to improve the efficiency of public funding. In the process we used non-market valuation techniques, as well as benefit functions’ transfer
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

We examined students in a college course who learned about one scholar's ideas through watching an audiovisual TV interview (i.e., visible author format) and about another scholar's ideas through reading a formal text description (i.e., invisible author format). For the invisible author, native language speakers scored significantly higher than the non-native language speakers on a corresponding exam question (i.e., a cognitive measure), generated more words on the exam question (i.e., a motivational measure), and mentioned the author's name more often in answering the exam question (i.e., an affective measure). For the visible author, the groups did not differ on any of these measures. These findings provide evidence for the idea that making the author visible through audiovisual TV interviews can eliminate the learning gap between native and non-native language speakers. 3 Universities around the world serve students who are non-native speakers of th
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
