The concept of information is central to several fields of research and professional practice. So many definitions have been put forward that complete inventory is unachievable while authors have failed to reach a consensus. In the face of the present impasse, innovative proposals could rouse information theorists to action, but literature surveys tend to emphasize the common traits of definitions. Reviewers are inclined to iron out originality in information models; thus the purpose of this paper is to discover the creativity of authors attempting to define the concept of information and to stimulate the progress of studies in this field.

Because the present inquiry could be influenced and distorted by personal criteria and opinions, the authors have adopted precise criteria and guidelines. It could be said the present approach approximates a statistical methodology.

The findings of this paper include (1) The authors found 32 original definitions of information which sometimes current surveys have overlooked. (2) The authors found a relation between information theories and advances in information technology. (3) Overall, the authors found that researchers take account of a wide variety of perspectives yet overlook the notion of information as used by computing practitioners such as electronic engineers and software developers.

The authors comment on some limitations of the procedure that was followed. Results 1 and 3 open up new possibilities for theoretical research in the information domain.

This is an attempt to conduct a bibliographical inquiry driven by objective and scientific criteria; its value lies in the fact that final report has not been influenced by personal choice or arbitrary viewpoints.

The so‐called strategic information systems define systems that represent instruments able to provide a competitive advantage. In this case, the purpose of this paper is to go further and broaden the perspective to examine business sectors. Namely, information systems are conceived also as factors that reconfigure entire business systems.

The research strategy followed can be considered in the circle of the case study. Specifically the case is Yoox, a virtual boutique. The theoretical approach for answering to the questions how and why information systems are determinant in Yoox's development is based on Normann's work (Reframing Business). In fact, it outlines modalities through which information systems reconfigure value space and give details to forces enacted consequently.

The Yoox case study throws light on the fact that, actually, information systems can be a useful instrument not only for reformulating business models but also dynamics that characterize entire business sectors.

The perspective proposed is limited to marginal aspects of the fashion business, i.e. global brands such as Armani have been involved in pursuing new online distribution channels outsourcing these services to a Dot.com company like Yoox.

A business such as a virtual boutique for a multi‐brand fashion and design is imitable due to the worldwide competition. The fact that Yoox became a provider of e‐commerce platform, forming the logistical side to the marketing strategies on the net, changes the scenario significantly. Yoox's mission is not only to sell fashion online but to provide a technological platform for e‐commerce. In this way, Armani, at first, was a Yoox provider but now it is also a customer. In some sense, the rules of the game of the fashion sector, have been, albeit marginally, modified.

The purpose of the editorial is to remember Professor Alessandro D'Atri, a pioneering Information Systems Scholar with whom the author collaborated for about 15 years. The main outcome of such collaboration is the conference Ethicomp 1999 in Rome. Following that conference the author has started elaborating a paper “Metaethics and the future of computer ethics” (Marturano) which was widely cited and quoted in the field. Thence the author has discussed its impact in the field and discussed some following papers dealing with similar topics. It emerged that such a paper is still a valid one for its perspectives but still not understood as for most of its ethical suggestions.

The paper is mainly philosophical and critical. It uses mostly critical analysis of papers dealing with the same topics.

The perspectives and the seminal ideas of the author's paper “Metaethics and the future of computer ethics” (Marturano) are still valid and, in some extent, are more fruitful than some following papers covering the same topics.

The value of this guest editorial is in remembering a very valuable and pioneering scholar – Alessandro D'Atri and comparing the author's paper's findings with other similar papers, which results in a better understanding of theoretical problems in the discipline.

The purpose of this paper is to identify the factors influencing the growth of healthcare virtual communities of practice (VCoPs) through a seven-year longitudinal study conducted using metrics from social-network and semantic analysis. By studying online communication along the three dimensions of social interactions (connectivity, interactivity and language use), the authors aim to provide VCoP managers with valuable insights to improve the success of their communities.

Communications over a period of seven years (April 2008 to April 2015) and between 14,000 members of 16 different healthcare VCoPs coexisting on the same web platform were analysed. Multilevel regression models were used to reveal the main determinants of community growth over time. Independent variables were derived from social network and semantic analysis measures.

Results show that structural and content-based variables predict the growth of the community. Progressively, more people will join a community if its structure is more centralised, leaders are more dynamic (they rotate more) and the language used in the posts is less complex.

The available data set included one Web platform and a limited number of control variables. To consolidate the findings of the present study, the experiment should be replicated on other healthcare VCoPs.

The study provides useful recommendations for setting up and nurturing the growth of professional communities, considering, at the same time, the interaction patterns among the community members, the dynamic evolution of these interactions and the use of language. New analytical tools are presented, together with the use of innovative interaction metrics, that can significantly influence community growth, such as rotating leadership.
