Due to the expansion and growth of information technologies, much of human knowledge is now recorded on digital media. A new problem in the digital universe has arisen: Digital Preservation. This chapter addresses the problems of Digital Preservation and focuses on the conceptual model within a specific class of digital objects: Relational Databases. Previously, a neutral format was adopted to pursue the goal of platform independence and to achieve a standard format in the digital preservation of relational databases, both data and structure (logical model). The authors address the preservation of relational databases by focusing on the conceptual model of the database, considering the database semantics as an important preservation “property.” For the representation of this higher layer of abstraction present in databases, they use an ontology-based approach. At this higher abstraction level exists inherent Knowledge associated to the database semantics that the authors tentatively represent using “Web Ontology Language” (OWL). From the initial prototype, they develop a framework (supported by case studies) and establish a mapping algorithm for the conversion between databases and OWL. The ontology approach is adopted to formalize the knowledge associated to the conceptual model of the database and also a methodology to create an abstract representation of it. The system is based on the functional axes (ingestion, administration, dissemination, and preservation) of the OAIS reference model.

In journalism studies, an interest in emotions has gathered momentum during the last decade, leading to an increasingly diverse investigation of the affective and emotional aspects of production, text and audience engagement with journalism which we describe as an “emotional turn.” The attention to emotion in journalism studies is a relatively recent development, sustained by the concurrent rise of digital information technologies that have accentuated the emotional and affective everyday use of media, as well as the increasing mobilization, exploitation and capitalization of emotions in digital media. This special issue both builds upon research on emotion in journalism studies and aims to extend it by examining new theoretical and methodological tools, and areas of empirical analysis, to engage with emotion or affect across the contexts of journalistic production, content and consumption. In proclaiming ‘an emotional turn’ in journalism studies, the intention of this special issue is not to suggest a paradigm shift or a major change in the prevailing research agenda in the field. Rather, against the backdrop of the increasingly diverse field of journalism studies, it is to point out that the relationship between journalism and emotion represents a rapidly developing area of inquiry, which opens up for new research agendas.

Beginning in the early 1970’s with the invention of the microprocessor, mass use of information technologies worldwide coincided with the appearance of a nodally-linked network of digital interconnectivity, or ‘network society’ (Castells, 1996). The network society’s exponential growth correlates with a rise in use of digital networking media by various sects and denominations of the Christian religion. Today, growing numbers of Christian organizations integrate digital media into both their approach to worship and the dissemination of the Holy Scriptures. This paper argues that the use of digital media by these organizations is indicative of the creation of a “religious network society” exhibiting identical structural paradigms to Castells’ (1996) network society. By virtue of the media deployed within it, the ‘religious network society’ fosters a mass culture of digital participation characterized by a rapid fragmentation of religious messaging and an over-sharing of personal religious beliefs. However, the religious network society also erodes Christianity’s hierarchical structures of authority (Turner, 2007). It is argued that these structures are being replaced with a banal form of religion emphasizing spirituality and individual self-expression at the expense of tradition (Campbell, 2012; Hjarvard, 2013). Moreover, purpose alterations to Christianity’s authority structures and approach to worship are indicative of a much larger shift in the religion, in which rising digital media use may in fact imply a decline in Christianity’s societal influence.

The increase in the use of information technologies encompasses all educational and social issues, even changing intergenerational skills. It is considered that the most conditioned to this effect are adolescents and young people. This research is a literary review of various studies on addiction and Internet abuse and presents relevant results of the situation of college students and their level of Internet use. The study was developed in seven educational units of Ecuador, with a sample of n = 773 students (53.6% men and 46.4% women). An instrument with sufficient validation guarantees (α.94) has been applied, verified by means of a factorial analysis of main components, which determined two study factors in the use of the Internet and loss of control and interference with life. Through a statistical treatment (Pearson) a good correlation was established (,62) between the two study dimensions, which is a concern in the educational field.

Ontologies are spreading more and more in the field of information technologies as a privileged solution allowing the formalization of knowledge. The theoretical model of ontologies is most promising. They are increasingly ubiquitous given the benefits they present. Despite the proliferation of research proposing approaches dedicated to the design of a database from an ontology, the tools to design a database from an ontology are rare or inaccessible. Thus, in this contribution, we present our approach for the development of an Eclipse Plug-in, in order to automatically generate a conceptual model of a relational database from an ontology. To evaluate the usefulness of our approach, we used our resulting Eclipse Plug-in to automatically generate a conceptual model of a relational database from an ontology, customize it, and automatically generate the corresponding SQL script for Data Definition. The results of this experiment showed that our Plug-in constitutes a concretization of our approach and a means of automatic translation from the ontological model to the relational model.

To preserve digitally encoded information over a long term following the OAIS Reference Model requires that the information remains accessible, understandable and usable by a specified Designated Community. These are significant challenges for repositories. It will be argued that infrastructure which is needed to support this preservation must be seen in the context of the broader science data infrastructure which international and national funders seek to put in place. Moreover aspects of the preservation components of this infrastructure must themselves be preservable, resulting in a recursive system which must also be highly adaptable, loosely coupled and asynchronous. Even more difficult is to be able to judge whether any proposal is actually likely to be effective. From the earliest discussions of concerns about the preservability of digital objects there have been calls for some way of judging the quality of digital repositories. In this chapter several interrelated efforts which contribute to solutions for these issues will be outlined. Evidence about the challenges which must be overcome and the consistency of demands across nations, disciplines and organisations will be presented, based on extensive surveys which have been carried out by the PARSE.Insight project (http://www.parse-insight.eu). The key points about the revision of the OAIS Reference Model which is underway will be provided; OAIS provides many of the key concepts which underpin the efforts to judge solutions. In the past few years the Trustworthy Repositories Audit and Certification: Criteria and Checklist (TRAC) document has been produced, as well as a number of related checklists. These efforts provide the background of the international effort (the RAC Working Group http://wiki.digitalrepositoryauditandcertification.org) to produce a full ISO standard on which an accreditation and certification process can be built. If successful this standard and associated processes will allow funders to have an independent evaluation of the effectiveness of the archives they support and data producers to have a basis for deciding which repository to entrust with their valuable data. It could shape the digital preservation market. The CASPAR project (http://www.casparpreserves.eu) is an EU part funded project with total spend of 16MEuros which is trying to faithfully implement almost all aspects of the OAIS Reference Model in particular the Information Model. The latter involves tools for capturing all types of Representation Information (Structure, Semantics and all Other types), and tools for defining the Designated Community. This chapter will describe implementations of tools and infrastructure components to support repositories in their task of long term preservation of digital resources, including the capture and preservation of digital rights management and evidence of authenticity associated with digital objects. In order to justify their existence, most repositories must also support contemporaneous use of contemporary as well as “historical” resources; the authors will show how the same techniques can support both, and hence link to the fuller science data infrastructure.

Information Technology (IT) capabilities play a fundamental role on process innovation and organizational performance. Likewise, corporate entrepreneurship (CE) plays a vital role in the improvement of performance, as the employees' profile is determinant for the success of these organizations. Previous literature relating to IT and CE reveals how little attention has been paid to relationship between these constructs, and what exists is only partial. This research conceptualizes the relationship between IT capabilities, CE, and innovation on the organizational performance. It is intended as a contribution to the ongoing conceptual development of this area and provides initial guidance for future empirical evidence. Thus, the authors advance a synthesized conceptual model in order to evaluate the influence of IT capabilities (IT flexibility, IT integration and IT alignment) to the CE process, through innovation on the organizational performance. The authors create an initial construction of the scenery grounded in past literature, which is refined and reinforced into a conceptual model advancing in theoretical development in the field. Some future research and implications are discussed.

An integrative model explaining intentions to use an information technology is proposed. The primary objective is to obtain a clearer picture of how intentions are formed, and draws on previous research such as the Technology Acceptance Model (Davis, Bagozzi and Warshaw, 1989) and the Decomposed Theory of Planned Behavior (Taylor and Todd, 1995a). The conceptual model was tested using questionnaire responses from 189 subjects, measured at two time periods approximately two months apart. The results generally supported the hypothesized relationships, and revealed strong influences of both personal innovativeness and computer self-efficacy.

This chapter introduces the UML profile for OWL as an essential instrument for bridging the gap between the legacy relational databases and OWL ontologies. We address one of the long-standing relational database design problems where initial conceptual model (a semantically clear domain conceptualization ontology) gets “lost” during conversion into the normalized database schema. The problem is that such “loss” makes database inaccessible for direct query by domain experts familiar with the conceptual model only. This problem can be avoided by exporting the database into RDF according to the original conceptual model (OWL ontology) and formulating semantically clear queries in SPARQL over the RDF database. Through a detailed example we show how UML/OWL profile is facilitating this new and promising approach.
