3D LITHOSTRATIGRAPHIC MODEL AS SUPPORT FOR DEVELOPMENT OF A GROUNDWATER FLOW MODEL: THE SARNO PLAIN (ITALY) CASE STUDY
No full textThe aim of this paper is to identify a computer based methodology in order to draw up a lithostratigraphic 3D model of an aquifer so as to develop a groundwater flow model in a part of it, useful to define some parameters involved in the evaluation of the water balance. The methodology was applied in two sample areas located in the Sarno Plain (Italy) affected by strong groundwater subflow.
The stratigraphical reconstruction of the study areas was obtained by interpolating stratigraphical data from analyzed and codified boreholes. The software used for the lithostratigraphic model creation is Rockworks 2006, which allows the construction of a 3D model (using grid-models or voxel matrix models) and its three-dimensional or bi-dimensional representation.
Starting from the obtained lithostratigraphic model, a numeric model was implemented to simulate the flow in the groundwater bodies.
The software used to reach this aim is Groundwater Vistas 5, which supplies a graphic interface for MODFLOW, a finite-difference model useful to study the groundwater flow.
The methodology used has allowed to value the entity of the groundwater subflow coming from carbonate structure of the Lattari Mts. and from the volcanic aquifer of Somma-Vesuvious towards the Sarno Plain
La formazione per il cambiamento
No full textDa sempre la scuola è luogo di tras-form-azione, che va al di là della formazione degli stessi allievi poiché
la scuola stessa trasformandosi induce cambiamenti anche negli stessi docenti. Appare evidente che,
parallelamente alla “formazione continua”, il processo di tras-formazione continua investe prepotentemente il
luogo principe in cui ad essa si dà azione: la scuola. Anche la scuola, al pari di ogni altra organizzazione, è
un’entità complessa il cui efficace ed efficiente funzionamento dipende dalla qualità delle relazioni tra vari
elementi (individui, gruppi, strutture, tecnologie, informazioni) interdipendenti, in modo ripetuto nel tempo
(Franco, De Simone, 2011). Ne consegue che la qualità del risultato dipenderà dalle modalità di funzionamento
del sistema complessivo che subisce e crea cambiamenti (Sangiorgi, 2007). Analisi teoriche ed esperienze
concrete dimostrano che esistono fattori critici di insuccesso con valore universale che possono ostacolare
l’accettazione, la collaborazione e lo sforzo comune per l’esito positivo di un cambiamento organizzativo. Tra
questi la letteratura in tema di change management individua nel concetto di stress uno dei fattori
fondamentali ostacolante i programmi di cambiamento e sviluppo. Lo stress è la reazione avversa ad eccessive
pressioni tali per cui l’individuo non si sente in grado di corrispondere alle richieste o aspettative in lui riposte.
A tutto ciò va poi aggiunto il fatto che gli insegnanti sono inseriti in una complessa rete di relazioni e richieste di
ruolo davvero difficile da gestire e che spesso travalicano il ruolo di insegnante (che diviene una commistione
tra docente-padre/madre-mediatore-educatore). Poiché esso non può essere eliminato diventa essenziale
comprenderne i meccanismi, le dinamiche e i modi in cui può essere gestito e moderato (Kreitner, Kinicki,
2004) intervenendo sulle competenze e professionalità delle persone, aumentandole o potenziandole attraverso
specifici corsi e percorsi di sviluppo e cambiamento (Favretto, 1994). Tuttavia, a seconda della portata ed
estensione del suo contenuto, il cambiamento provoca resistenze che tendono ad assumere una maggiore
significatività laddove si intraprendono iniziative di più ampia portata e che possono essere superate ricorrendo
a strategie e strumenti diversi (De Vita, Mercurio, Testa, 2007). Per il buon esito sono quindi cruciali il
contenuto e la modalità di erogazione della formazione
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
