Impiego della FPA per la stima dei costi di personalizzazione di sistemi ERP
No full textIl problema della valutazione dei costi di customizing ovvero della personalizzazione del software standard si è posto solo di recente in seguito alla progressiva ed imprevista crescita dei costi di customizing dei sistemi integrati di tipo Enterprice Resource Planning (ERP). In molte aziende, infatti, la fase di adozione ha evidenziato non poche difficoltà di adeguamento del contesto organizzativo alle procedure standard dell'ERP; questo ha determinato la richiesta di nuove e non previste funzionalità da sviluppare ed implementare in aggiunta a quelle standard fornite dal sistema ERP. La conseguenza è stata quella della crescita esponenziale dello sforzo di customizing. La Function Point Analysis (FPA) è una metrica standard per la misurazione della dimensione del software che viene, di fatto, applicata da un gran numero di aziende nel mondo. Il suo uso, ben collaudato per i progetti di sviluppo di software ad-hoc, risulta pionieristico per i progetti di acquisizione e manutenzione di software ERP. Questa ricerca individua le principali componenti di costo legate all’adozione di sistemi ERP soffermandosi, più in particolare, su quelle che compongono l’attività di customizing. Riesce infine ad applicare la FPA per la loro valorizzazione al fine di condurre un’analisi comparativa su dati empirici opportunamente raccolti. In conclusione il presente studio vuole essere una prima risposta al sentito bisogno di acquisire una maggiore consapevolezza dello sforzo di customizing dell'ERP; i suoi risultati potranno essere migliorati con la raccolta di ulteriori dati
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
A software metric research to evaluate the dimension of standard systems'customization
No full textThe issue concerning the evaluation of the customizing dimension was only recently born with the progressive increase of the ERP systems customizing costs. After having chosen the ERP system, manu enterprises found it rather difficult to conform to the standard procedures during the implementing phase; as a consequence, there was the request of new and ad-hoc procedures to be added to the standard ones supplied by the ERP system. So, the customizing effort inreased exponentially. The Function Point Analysis is a standard dimensional software metric having an international spread and it is applied by a large number of enterprises in the world. Its use is well known for "ad hoc" software projects but it is a novelty when applied in the acqiring and maintenance phase of "Commercial-Off-The-Shelf" (COTS) software (whose category includes the ERP systems).
our resarch describes thae main cost items of ERP systems, the FPA actual use applied to ERP environment and a simple equation model for the effort estimate: this model is just a first step towards the control of the ERP system customizing effort, that will be even more accurate when a geater quantity of empirical data are collected
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
