Information Systems for eGovernment: A Quality-of-Service Perspective
No full textThe success of public sector investment in eGovernment initiatives strongly depends on effectively exploiting all aspects of ICT systems and infrastructures. The related objectives are hardly reachable without methodological frameworks that provide a holistic perspective and knowledge on the contexts of eGovernment initiatives. Yet public administrators usually have a mix of legal and administrative knowledge, while lacking an information systems background. With this book, Viscusi, Batini and Mecella provide a comprehensive methodology for service-oriented information systems planning, with special emphasis on eGovernment initiatives. They present the eG4M methodology which structurally supports the development of optimal eGovernment plans, considering technological, organizational, legal, economic and social aspects alike. The approach is focused on two pillars: the quality of the provided services and related processes, and the quality of the data managed in the administrative processes and services. The book is written for public administrators, decision-makers, practitioners, ICT professionals and graduate students, providing a comprehensive perspective of the challenges, opportunities and decisions related to strategic and operational planning of service-oriented information systems in eGovernment. © Springer-Verlag Berlin Heidelberg 2010.

Towards the development of an agile marketing capability
No full textThis study aims to explore the key theoretical foundations for the development of an Agile Marketing Capability (AMC) framework, through the performance of an in-depth literature review on IT and dynamic marketing capabilities. Our framework enables us to (1) advance the understanding of how IT and dynamic marketing capabilities evolve into agile marketing capabilities (2) unpack the distinctive and ongoing processes and features through which the Agile Marketing capabilities are accomplished (3) define the key propositions for a new marketing capability: the Agile Marketing Capability. This work may represent a useful framework for managers and decision makers to better understand the competitive advantages which could derive from the employment of agile marketing capabilities in order to improve their skills in challenging the continuous changes in market and customers’ needs
Information Systems: Editorial
No full textResearch efforts on structured data, multimedia, and services have involved non-overlapping communities. However, from a user perspective, the three kinds of information should behave and be accessed similarly. Instead, a user has to deal with different tools in order to gain a complete knowledge about a domain. There is no integrated view comprising data, multimedia and services retrieved by the specific tools that is automatically computed. A unified approach for dealing with different kinds of information may allow searches across different domains and different starting points / results in the searching processes.Multiple and challenging research issues have to be addressed to achieve this goal, including: mediating among different models for representing information, developing new techniques for extracting and mapping relevant information from heterogeneous kinds of data, devising innovative paradigms for formulating and processing queries ranging over both (multimedia) data and services, investigating new models for visualizing the results and allowing the user to easily manipulate them.This special issue "Semantic Integration of Data, Multimedia, and Services" presents advances in data, multimedia, and services interoperability
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
