U.S. federal websites are required to be accessible for people with impairments. However, despite the existing regulations and guidelines, many federal websites continue to be inaccessible, and accessibility policy statements available on federal websites often do not provide any useful information. This paper provides three contributions to the research literature: (1) an accessibility evaluation of 100 federal home pages using both human and automated methods, (2) a content analysis of existing website accessibility policy statements, and (3) a discussion of the relationship between actual Section 508 compliance and the existing accessibility policy statements on a website. The paper concludes with recommendations for improving policy related to Section 508 compliance for websites.  相似文献

The HIV/AIDS pandemic is recognized globally as the greatest health challenge of the present generation. It is widely acknowledged to be the foremost killer disease in Africa. Since the first Aids case was publicly announced in 1986, the astronomical increase in victims has been a matter of concern. The rates of HIV/AIDS infection indicate that Nigeria currently has the third largest rate of HIV/AIDS patients. The UNAIDS (2008) reported that as at 2007, the population of children and adults with HIV/AIDS in Nigeria was 2.6 million. Due to the fact that there is no cure for the virus, HIV/AIDS, counselling is an important aspect of its management. Counsellors in Nigeria have provided pre- and post-test counselling, preventive education seminars, and referrals to other health professionals. However, counsellors’ efforts have only yielded limited success because of a number of major challenges. This paper examines some of the challenges involved in meeting the HIV/AIDS counselling needs of Nigerians. Specifically, it addresses challenges faced by government, potential clients, and the Counselling Association of Nigeria, as well as challenges associated with existing cultural practices (indigenous counselling practices). It concludes with specific recommendations for various stakeholders.  相似文献

This article examines the practical ways of handling Internet connectivity challenges in a typical university academic library setting in Nigeria, using Kenneth Dike Library (KDL), University of Ibadan, as a case study. Both internal and external factors are responsible for the challenges being experienced in terms of Internet connectivity in KDL. The current state of Internet connectivity within the KDL is presented. Also discussed are an overview of the previous model of Local Area Network (LAN) within the KDL, the challenges associated with the previous model, an overview of the new LAN model and discussion/way forward. Finally, conclusion and recommendations are presented.  相似文献

This article reports on a survey study on the adoption and implementation of automation projects in federal university libraries in the south-west of Nigeria (SWN). The objectives are to ascertain the implementation status of automation projects, discuss the accruable benefits, investigate the library management system software being used, determine the modules already activated and fully implemented and their web presence, highlight the challenges encountered, draw conclusions and recommendations on enhancing successful implementation of library automation projects in Nigeria. The method used for gathering data for the study is questionnaire-based survey, using google form template. The findings of the study are that all the six federal university libraries in the SWN have adopted and implemented automation; two out of them are using open source integrated library automation software (Koha), one library uses in-house built integrated library system (ILS), while the remaining three use different proprietary software for their automation projects; and all the ILSs being used for automation projects are interoperable. The conclusion from the study is that the effective performance of libraries lies in the ability to access research materials and other relevant information contents with remarkable ease. This becomes achievable when libraries adopt and implement automation in their respective domains.  相似文献

The working assumption of this research is that the utilization of information technology (IT) and IT-based practices in any part of the world currently is taking place within the globalization trends. In recent times, studies in information systems (IS) are beginning to examine whether the globalization process portends homogeneity for developing countries' organizations or whether these organizations can utilize IT and IT-based management techniques according to the sociocultural requirements of their contexts. These studies show the importance of the local context and, more specifically, the importance of adapting global IT-based practices when implementing them in developing countries. However, the precise nature of these adaptations and the factors that shape them are still poorly understood--leaving this a fruitful area for research. In line with this view, this article explores how a Nigerian bank implemented and adapted a global IT-based technique, the factors that influence such adaptations, and what results are achieved.  相似文献

New information communication technologies, such as the Internet and electronic publishing, not only enhance the range of publications that libraries can provide for their users but also increase the speed with which such requests can be met. This article describes the development of electronic document delivery (EDD) at the Kenneth Dike Library at the University of Ibadan, Nigeria. A successful EDD program depends upon good intranet and Internet network systems, document availability, user awareness and training, and ease of use. The major challenge to this service is inconsistent power supply, which the university is addressing with the aid of a grant from the MacArthur Foundation for backup electric generators and a university solar energy project. It is hoped that this will assure better and more reliable power service in support of EDD in future. New information delivery regulations and laws guiding adequate service will also emerge but must be properly applied for effective and positive results.  相似文献

Abstract

Retrospective conversion of bibliographic records is not a recent practice among Nigerian academic libraries. However, the end product of this process, which is a functional Online Pubic Access Catalog (OPAC) has been underwhelming. This is due to various challenges that have hindered the libraries from achieving a successful retrospective conversion. Some of these challenges include unreliable software, lack of a union catalog, and sheer absence of exchange of information among the libraries. This study therefore measures the practices and experiences of twenty Nigerian University Libraries in the course of carrying out retrospective conversion of their resources using the KOHA library software. The study adopted a survey method of research with a self-developed questionnaire as the instrument of data collection. Data analysis was with the aid of the SPSS software and the presentation was done using simple frequency and percentage. Findings show that erratic power supply and low Internet bandwidth are the major challenges facing Nigerian libraries in the course of retrospective conversion.  相似文献

The effect of iodine deficiency (ID) on thyroid function in African women during pregnancy and postnatal period was examined, for which very limited information is available. Serum T4, T3, TSH, TBG, thyroxine binding capacity (TBK), free thyroxine index (FT4I=T4/TBK) and T4/TBG were determined by ELISA technique in 32 pregnant women (resident of Plateau state, Nigeria- an ID zone) through pregnancy upto term delivery, and in 5 women up to 6 weeks post delivery. Urinary iodide level was measured at delivery to determine the degree of iodine deficiency. Results were matched with a non pregnant control comprising 44 subjects. 5555 birth weights (BW) of term babies in the region were analysed to determine the prevalence of ‘small for dates’ (SFD) babies in the population. Results show that the level of serum FT4I was elevated very significantly at late gestation (P<.001) but the women were not hyperthyroid, suggesting a marked disturbance in binding of T4 with TBG during pregnancy. Five women with SFD babies were found in ‘compensated hypothyroid state’ and showed a significant depression (p<.01) in serum T4/TBG, T4, FT4I and T3 levels to a low normal range, with a concurrent significant rise (p.<.001) in TSH level (above normal range) throughout pregnancy. Incidence of SFD babies was higher (p.<.001) in ID zone (Bassa 15.2%) compared to control zone (Jos 9.8%). It is concluded that a state of maternal ‘subclinical (compensated) hypothyroidism’ during pregnancy possibly plays an important role in the aetiopathogenesis of SFD babies in Africans. A normal reference range for thyroid parameters at various stages of pregnancy in healthy African women is established for the first time.  相似文献
