Stephanie Grade 3 Towers interview excerpts
No full textIn this edited clip, Stephanie answers questions from Researcher Amy Martino about her problem solving on the three-tall selecting from two colors towers problem. Stephanie explains how she used her solution to the four-tall problem to solve towers that are three-tall.Transcript is also available.Robert B. Davis Institute for Learning. (1990).

GISDAY 2013. IL GIS PER IL GOVERNO E LA GESTIONE DEL TERRITORIO
No full textCome già avvenuto negli anni 2008, 2009, 2010, 2011, 2012 si è tenuto il giorno 20 novembre 2013 l’evento “GIS DAY 2013: il GIS per il governo e la gestione del territorio” nel Dipartimento di Architettura dell’Università degli Studi di Napoli Federico II. Questa sesta raccolta monografica contiene articoli riguardanti i Sistemi Informativi Territoriali, scritti da esperti di questa tecnologia intervenuti all’evento per presentare i loro lavori. Si ringraziano tutti gli autori che hanno inviato il loro contributo ed ESRIITALIA, la cui sponsorizzazione è stata fondamentale per la riuscita e l’organizzazione dell’evento. Un particolare ringraziamento alla sig.ra Silvia d’Ambrosio che ha coordinato la realizzazione complessiva dell’evento medesimo, in particolare tenendo i contatti con gli interessati, i docenti e i relatori ed ha gestito la redazione degli abstract e la loro pubblicazione
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
Towers with Stephanie and Dana, Clip 1 of 5: Introducing and working on the problem
No full textIn this clip, researcher Amy Martino introduces the following problem to the students: “How many different towers four blocks tall can you build when selecting from two colors?” Dana and Stephanie have bags of Unifix cubes at their desks and begin working on the problem by building towers independently. They run out of Unifix cubes, and after Amy encourages them to work together, they work on a solution together by comparing each of Dana’s towers to each of Stephanie’s, eliminating the duplicates.Transcript is also available.Robert B.

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

Hotspots Detection in Spatial Analysis: an Application to Military War
No full textWe show a new approach for detecting hotspots in spatial analysis based on the Extended Gustafson-Kessel clustering method encapsulated in a Geographic In-formation System tool. This algorithm gives (in the bidimensional case) ellipses as cluster prototypes to be considered hotspots on the geographic map and we study their spatio-temporal evolution. The data consist of geo-referenced patterns corresponding to positions of Taliban’s attacks against civilians and soldiers in Afghanistan happened during the period 2004÷2010
Shirts and Pants with Stephanie and Dana, Clip 1 of 2: Introducing and working on the problem
No full textDuring this session, the students begin by working on the following problem: “Stephen has a white shirt, a blue shirt and a yellow shirt. He has a pair of blue jeans and a pair of white jeans. How many different outfits can he make?” Researcher Amy Martino introduces the problem by stressing that she is interested in how they solve the problem rather than in just the answer. Stephanie and Dana draw pictures to represent the shirts and pants, labeling them with the letters b, w, and y to represent the colors blue, white, and yellow, and then draw lines from each of the shirts to each of the pants. After they are both sure they cannot make any more combinations, they explain their solution to Amy and then write up their solution on a large paper.Transcript and student work are also available
