Using Google Analytics to Evaluate the Usability of E-Commerce Sites

The success of an e-commerce site is, in part, related to how easy it is to use. This research investigated whether advanced web metrics, calculated using Google Analytics software, could be used to evaluate the overall usability of e-commerce sites, and also to identify potential usability problem areas. Web metric data are easy to collect but analysis and interpretation are time-consuming. E-commerce site managers therefore need to be sure that employing web analytics can effectively improve the usability of their websites. The research suggested specific web metrics that are useful for quickly indicating general usability problem areas and specific pages in an e-commerce site that have usability problems. However, what they cannot do is provide in-depth detail about specific problems that might be present on a page.

Developing a model for e-prints and open access journal content in UK further and higher education

A study carried out for the UK Joint Information Systems Committee examined models for the provision of access to material in institutional and subject‐based archives and in open access journals. Their relative merits were considered, addressing not only technical concerns but also how e‐print provision (by authors) can be achieved – an essential factor for an effective e‐print delivery service (for users). A ‘harvesting’ model is recommended, where the metadata of articles deposited in distributed archives are harvested, stored and enhanced by a national service. This model has major advantages over the alternatives of a national centralized service or a completely decentralized one. Options for the implementation of a service based on the harvesting model are presented.

RoMEO Studies 1 : the impact of copyright ownership on academic author self-archiving

This is the first of a series of studies emanating from the UK JISC‐funded RoMEO Project (Rights Metadata for Open‐archiving) which investigated the IPR issues relating to academic author self‐archiving of research papers. It considers the claims for copyright ownership in research papers by universities, academics, and publishers by drawing on the literature, a survey of 542 academic authors and an analysis of 80 journal publisher copyright transfer agreements. The paper concludes that self‐archiving is not best supported by copyright transfer to publishers. It recommends that universities assert their interest in copyright ownership in the long term, that academics retain rights in the short term, and that publishers consider new ways of protecting the value they add through journal publishing.

RoMEO Studies 2: How Academics Want to Protect their Open-Access Research Papers

This paper is the second in a series of studies (see E. Gadd, C. Oppenheim and S. Probets. RoMEO studies 1: the impact of copyright ownership on author-self-archiving, Journal of Documentation 59(3) (2003) 243-277) emanating from the UK JISC-funded RoMEO Project (Rights Metadata for Open-archiving). It considers the protection for research papers afforded by UK copyright law, and by e-journal licences. It compares this with the protection required by academic authors for open-access research papers as discovered by the RoMEO academic author survey. The survey used the Open Digital Rights Language (ODRL) as a framework for collecting views from 542 academics as to the permissions, restrictions and conditions they wanted to assert over their works. Responses from self-archivers and non-archivers are compared. The paper concludes that most academic authors are primarily interested in preserving their moral rights, and that the protection offered research papers by copyright law is way in excess of that required by most academics. It also raises concerns about the level of protection enforced by e-journal licence agreements.

Authors’ Awareness and Attitudes Toward Open Access Repositories

This article investigates the awareness of scholarly authors toward open access repositories and the factors that motivate their use of these repositories. The article reports on the findings obtained from a mixed methods approach which involved a questionnaire returned by over 3000 respondents, supplemented by four focus groups held across Europe in the summer 2009. The research found that although there was a good understanding and appreciation of the ethos of open access in general, there were clear differences between scholars from different disciplinary backgrounds in their understanding of open access repositories and their motivations for depositing articles within them. This research forms the first part of a longitudinal study that will track the changing behaviors and attitudes of authors toward open access repositories.

A comparison of usability evaluation methods for evaluating e-commerce websites

The importance of evaluating the usability of e-commerce websites is well recognised. User testing and heuristic evaluation methods are commonly used to evaluate the usability of such sites, but just how effective are these for identifying specific problems? This article describes an evaluation of these methods by comparing the number, severity and type of usability problems identified by each one. The cost of employing these methods is also considered. The findings highlight the number and severity level of 44 specific usability problem areas which were uniquely identified by either user testing or heuristic evaluation methods, common problems that were identified by both methods, and problems that were missed by each method. The results show that user testing uniquely identified major problems related to four specific areas and minor problems related to one area. Conversely, the heuristic evaluation uniquely identified minor problems in eight specific areas and major problems in three areas.

RoMEO Studies 3: How academics expect to use open-access research papers

This paper is the third in a series of studies emanating from the UK JISC- funded RoMEO Project (Rights Metadata for Open-archiving). It considers previous studies of the usage of electronic journal articles through a literature survey. It then reports on the results of a survey of 542 academic authors as to how they expected to use open-access research papers. This data is compared with results from the second of the RoMEO Studies series as to how academics wished to protect their open-access research papers. The ways in which academics expect to use open-access works (including activities, restrictions and conditions) are described. It concludes that academics-as-users do not expect to perform all the activities with openaccess research papers that academics-as-authors would allow. Thus the rights metadata proposed by the RoMEO Project would appear to meet the usage requirements of most academics.

Documentation for institutional repositories

The documentation of seven academic institutional repositories (IRs) was compared and contrasted. This was followed by semi‐structured interviews with six practitioners experienced in the set‐up, management and maintenance of IRs, including representatives of three JISC FAIR projects. The aim was to identify the requirements of policy documentation provided by IRs. Although many issues were found to be handled differently, several common factors emerged. These included the importance of developing documentation in collaboration with academics, departments and senior management. Policies should be formulated only when the aims of the IR have been clearly defined and the documentation itself should be concise and understandable, with the rights and responsibilities of stakeholders clearly presented.

Substituting outline fonts for bitmap fonts in archived PDF files

As collections of archived digital documents continue to grow the maintenance of an archive, and the quality of reproduction from the archived format, become important long‐term considerations. In particular, Adobes portable document format (PDF) is now an important ‘final form’ standard for archiving and distributing electronic versions of technical documents. It is important that all embedded images in the PDF, and any fonts used for text rendering, should at the very minimum be easily readable on screen. Unfortunately, because PDF is based on PostScript technology, it allows the embedding of bitmap fonts in Adobe Type 3 format as well as higher‐quality outline fonts in TrueType or Adobe Type 1 formats. Bitmap fonts do not generally perform well when they are scaled and rendered on low‐resolution devices such as workstation screens.

E‐commerce websites for developing countries – a usability evaluation framework

Purpose – The purpose of this paper is to develop a methodological usability evaluation approach for e‐commerce websites in developing countries.Design/methodology/approach – A multi‐faceted usability evaluation of three Jordanian e‐commerce websites was used, where three usability methods (user testing, heuristic evaluation and web analytics) were applied to the sites.Findings – A four‐step approach was developed to facilitate the evaluation of e‐commerce sites, mindful of the advantages and disadvantages of the methods used in identifying specific usability problems.Research limitations/implications – The approach was developed and tested using Jordanian users, experts and e‐commerce sites. The study compared the ability of the methods to detect problems that were present, however, usability issues not present on any of the sites could not be considered when creating the approach.Practical implications – The approach helps e‐commerce retailers evaluate the usability of their websites and understand whic...
