    The economic-driven evaluation of information technology (IT) has become an important instrument in the management of IT projects. Numerous approaches have been developed to quantify the costs of an IT investment and its assumed profit, to evaluate its impact on business process performance, and to analyze the role of IT regarding the achievement of enterprise objectives. This paper discusses approaches for evaluating IT from an economic-driven perspective. Our comparison is based on a framework distinguishing between classification criteria and evaluation criteria. The former allow for the categorization of evaluation approaches based on their similarities and differences. The latter, by contrast, represent attributes that allow to evaluate the discussed approaches. Finally, we give an example of a typical economic-driven IT evaluation

    This paper is an empirical study of evaluation practices of electronic resources in university libraries in South East Nigeria. The study determines the criteria considered in evaluating electronic resources, the adequacy of use of the electronic resources and the extent of use of the electronic resources by university libraries in South East Nigeria. It employed a descriptive survey design. The population of the study was 2595 respondents consisting of 2509 postgraduate users and 86 librarians in collection development, serials and digital library (e-library). A 10% proportionate sampling technique was used to select a sample of 251 user respondents while all the 86 librarians working in collection development, serials and digital library units (e-library) were used. The survey used questionnaire and interview as instruments of data collection. Data collected were tabulated and analyzed using simple statistics (mean). The result revealed the criteria used by the libraries under study to evaluate their resources which include cost effectiveness based on the number of searches; relevance of the research on campus and the curriculum of the library users; dissatisfaction with a resource; access criteria on the technical reliability of the content provider; the database can be ranked by acquiring statistics; comparing duplication in various formats or overlap in full-text resources. The result also revealed that the greater number of the electronic resources is high adequacy and that all the electronic resources are used to a great extent by the users. That shows that the users are accessing it and using it for their research and learning. The study recommended regular evaluation of library electronic resources considering the stated criteria to ensure that users’ needs are met; the university libraries should ensure that electronic resources under subscription are properly evaluated and accessed by library users to guide in continuity or cancellation of the resources if otherwise

    Does social media usage matter? An analysis of online practices and digital media perceptions of communication practitioners in Europe

    Get PDF
    A key aspect for understanding and explaining online communication is the micro level of communication practitioners’ social media usage and their general attitudes towards digital platforms. This paper investigates how public relations practitioner's personal and professional use of social media is related to their perceptions of social media. A quantitative methodology was applied to perform this research. A population of 2710 professionals from 43 European countries working on different hierarchical levels both in communication departments and agencies across Europe were surveyed as part of a larger transnational online survey. Results show that practitioners with a high level of usage of social media give more importance to social media channels, influence of social media on internal and external stakeholders and relevance of key gatekeepers and stakeholders along with a better self-estimation of competences. Issues about diverse levels of overestimation of social media use, application and importance in the professional arena are also debated
