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
Assessing information systems practices in manufacturing SMEs
No full textThis paper presents the preliminary results of a survey carried out on a sample of 30 manufacturing SMEs in Northern Italy. The research focuses on the assessment of the Information System (IS) currently implemented in the considered organizations and aims at identifying strengths, weaknesses or inconsistencies, obtaining useful information in order to address new IT investment and to improve user satisfaction and corporate performance. With this paper we investigated the relations among IT expenditure, how the information system supports activities, and the deriving level of user satisfaction. The links among these aspects were examined subject to various endogenous and exogenous factors, such as corporate IT culture, business dimension, control structure, market approach and so on.
Empirical results seem to support a direct link among IT expenditure (more specifically running expenses) and the amount of activities supported by the IS, and show a strong relation among the support of relevant activities by means of the IS and user satisfaction. Various endogenous and exogenous factors were found as relevant antecedents of corporate expenditure
The PSS design GuRu methodology: Guidelines and rules generation to enhance PSS detailed design
No full textManufacturers are often compelled to navigate the transition towards servitisation. In relation to this phenomenon, the present work focuses on design problems related to physical product enhancement when the addition of a service component is needed. A methodology generating the most suitable technical directions and design ideas to be followed during the integrated product-service system (PSS) design is provided. These design directions are deployed per the design for product service supportability approach on two different levels: Guidelines (non-company and PSS specific) and rules (derived through design for X (DfX) approaches) specific to a company and a particular solution. An application case in an Italian company operating in the heating, ventilation, air-conditioning and refrigeration market is conducted
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
Check-up methodology of information systems in manufacturing SMEs
No full textItalian companies’ expenditure in Information Systems (IS) is lower than in other industrialized countries; this is due to a complex mix of factors, mainly related to a cultural deficiency. The lack of investment and expenditure in IS, especially within Italian SMEs, can be considered a relevant factor in explaining the sharp decrease of Italian competitiveness on international markets in the last 5-10 years. Aim of this paper is to present the IS Check-up Methodology developed at the INF-OS research centre; the main scope of this methodology the management IS within manufacturing SMEs, that is investigated with a twofold purpose: (i) at a general level, identifying and measuring the relations among the endogenous/exogenous factors, the IS choices and the results achieved; (ii) at a single firm level, supporting the analysed SMEs by supplying evidence on their IS policies’ strengths and weaknesses, in order to address new and more effective IS investments
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
