GIScience e i paesaggi d’acqua: prime considerazioni sull’applicazione di sketch map tool nel caso studio della diga di Occhito
No full textFra i possibili strumenti per studiare le connessioni fra popolazione e paesaggio ci sono i Public Participatory GIS. In quanto mezzo che hanno ancora un utilizzo limitato nella creazione di nuovi dati geografici attraverso il coinvolgimento dei locali, risulta quantomai importante analizzarne opportunità e limiti. Il contributo fornisce delle prime riflessioni sull’impiego della piattaforma Sketch Map Tool nell’analisi dei paesaggi d’acqua. Tale tool permette di condurre varie attività di mapping partecipativo, che vanno dalla preparazione dei dati, alla raccolta in campo e poi all’analisi dei dati on desk. Il lavoro presenta il processo partecipativo adottato nell’area interna del Fortore (Campobasso, Molise), e nello specifico nell’area in prossimità della diga artificiale di Occhito
The middle Fortore valley (Campobasso), a case of destructuring and restructuring of a waterscape: land use variability as an indicator of change
Full text linkLa media valle del Fortore può essere definita come un caso di waterscape. Infatti, oltre alla più diffusa idea di ruralità e di spopolamento, il Molise si caratterizzata per la presenza di importanti sistemi idrografici di diversi invasi artificiali. Difatti, nella regione si localizzano tre dighe di una certa ampiezza, tra cui quella di Occhito situata proprio nella media valle del Fortore. La sua realizzazione ha avviato un processo di destrutturazione del paesaggio e al contempo di artificializzazione del sistema fluviale. La ricerca che si propone, di carattere preliminare, vuole descrivere questo processo attraverso lo studio del paesaggio considerando le dinamiche cicliche di abbandoni e di ristrutturazioni. Indagando le variazioni avvenute nell’uso del suolo tra il 1800 e gli anni 2000 ed integrando in un sistema GIS dati noti in bibliografia e informazioni cartografiche, è stato possibile sia cogliere le stratificazioni del paesaggio sia evidenziare la necessità di una diversa gestione e pianificazione territoriale dell’area, caratterizzata da alcune fragilità ambientali. Tali analisi preliminari potranno fornire alcuni spunti per progetti di governace e sviluppo del territorio, in linea con le necessità degli Enti coinvolti nella gestione e funzionamento della diga di Occhito
The middle valley of Fortore can be defined as a case of waterscape. In fact, in addition to the more common idea of rurality and depopulation, the Molise region, is characterized by the presences of important hydrographic systems and the artificial water basins. In fact, in the region there are three important dams, one of this is the Occhito dam located in the middle valley of Fortore. Its realization has started a process of destructuring of the landscape and at the same time of artificialization of the river system. The analysis proposing wants to describe this process through the study of landscape considering the cyclical dynamics of abandonment and restructuring. By investigating the changes that occurred in land use between the 1800s and the 2000s and integrating previously known bibliographic data and cartographic information into a GIS system, it is possible both to pick up on the stratifications of the landscape and to highlight the need for different land management and planning in the area, which is characterized by certain environmental fragilities. These preliminary analyses may provide some insights for land governance and development projects, in line with the needs of the entities involved in the management and operation of the Occhito Dam
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
