Abstract

Data mining (DM) is part of a process by which information can be extracted from data or databases and used to inform decision making in a variety of contexts (Benoit, 2002; Michalski, Bratka & Kubat, 1997). DM includes a range of tools and methods for extractiog information; their use in the commercial sector for knowledge extraction and discovery has been one of the main driving forces in their development (Adriaans & Zantinge, 1996; Benoit, 2002). DM has been developed and applied in numerous areas. This review describes its use in analyzing health and medical information.

Abstract

This paper reports analysis of data from higher education institutions in the UK on their experience of the open-access (OA) publishing market working within a policy environment favoring "Gold" OA (OA publishing in journals). It models the "total cost of publication"-comprising costs of journal subscriptions, OA article-processing charges (APCs), and new administrative costs-for a sample of 24 institutions. APCs are shown to constitute 12% of the "total cost of publication," APC administration, 1%, and subscriptions, 87% (for a sample of seven publishers). APC expenditure in institutions rose between 2012 and 2014 at the same time as rising subscription costs. There was disproportionately high take up of Gold options for Health and Life Sciences articles. APC prices paid varied widely, with a mean APC of £1,586 in 2014. "Hybrid" options (subscription journals also offering OA for individual articles on payment of an APC) were considerably more expensive than fully OA titles, but the data indicate a correlation between APC price and journal quality (as reflected in the citation rates of journals). The policy implications of these developments are explored, particularly in relation to hybrid OA and potential of offsetting subscription and APC costs.

Abstract

Purpose - The purpose of this study is to determine the extent to which two existing models of information behaviour could explain the information behaviour of visually impaired people seeking health and social care information. Design/methodology/approach - The research was conducted within a constructivist paradigm. A total of 28 semi-structured interviews (face-to-face or telephone) with 31 visually impaired people were conducted. Framework analysis was used to analyse the results. Findings - This study identified several factors that may affect a visually impaired person's information behaviour. These related to the presence of other health conditions or disabilities, participants' understanding of the word "information", their interactions with information providers, their degree of independence, the support they received from friends and family, their acceptance of their own visual impairment, as well as their awareness of other visual impairments, their registration status and their willingness and ability to pay for aids, adaptations and equipment. Originality/ value - This study provides a new and valuable insight into the information behaviour of visually impaired people, as well as testing the applicability of a specific and generic information model to the information behaviour of visually impaired people seeking health and social care information.

Abstract

This paper reviews the worldwide growth of open-access (OA) repositories, 2005 to 2012, using data collected by the OpenDOAR project. Initial repository development was focused on North America, Western Europe, and Australasia, particularly the United States, United Kingdom, Germany, and Australia, followed by Japan. Since 2010, there has been repository growth in East Asia, South America, and Eastern Europe, especially in Taiwan, Brazil, and Poland. During the period, some countries, including France, Italy, and Spain, have maintained steady growth, whereas other countries, notably China and Russia, have experienced limited growth. Globally, repositories are predominantly institutional, multidisciplinary and English-language based. They typically use open-source OAI-compliant software but have immature licensing arrangements. Although the size of repositories is difficult to assess accurately, available data indicate that a small number of large repositories and a large number of small repositories make up the repository landscape. These trends are analyzed using innovation diffusion theory, which is shown to provide a useful explanatory framework for repository adoption at global, national, organizational, and individual levels. Major factors affecting both the initial development of repositories and their take-up include IT infrastructure, cultural factors, policy initiatives, awareness-raising activity, and usage mandates. Mandates are likely to be crucial in determining future repository development.

Abstract

Health informatics concerns the use of information and information and communication technologies within healthcare. Health informatics and information science need to take account of the unique aspects of health and medicine. The development of information systems and electronic records within health needs to consider the information needs and behaviour of all users. The sensitivity of personal health data raises ethical concerns for developing electronic records. E-health initiatives must actively involve users in the design, development, implementation and evaluation, and information science can contribute to understanding the needs and behaviour of user groups. Health informatics could make an important contribution to the ageing society and to reducing the digital divide and health divides within society. There is a need for an appropriate evidence base within health informatics to support future developments, and to ensure health informatics reaches its potential to improve the health and well-being of patients and the public.

Abstract

As open-access (OA) publishing funded by article-processing charges (APCs) becomes more widely accepted, academic institutions need to be aware of the "total cost of publication" (TCP), comprising subscription costs plus APCs and additional administration costs. This study analyzes data from 23 UK institutions covering the period 2007-2014 modeling the TCP. It shows a clear rise in centrally managed APC payments from 2012 onward, with payments projected to increase further. As well as evidencing the growing availability and acceptance of OA publishing, these trends reflect particular UK policy developments and funding arrangements intended to accelerate the move toward OA publishing ("Gold" OA). Although the mean value of APCs has been relatively stable, there was considerable variation in APC prices paid by institutions since 2007. In particular, "hybrid" subscription/OA journals were consistently more expensive than fully OA journals. Most APCs were paid to large "traditional" commercial publishers who also received considerable subscription income. New administrative costs reported by institutions varied considerably. The total cost of publication modeling shows that APCs are now a significant part of the TCP for academic institutions, in 2013 already constituting an average of 10% of the TCP (excluding administrative costs).
