A study was conducted to find out the types of CD products in Nigerian libraries and information centres, and the uses to which they are being put. The study also tried to find out the sources of funding of such products, information about users, hardware configuration, and training facilities available in the country. Of the 157 questionnaires sent out, 85 usable returns (a 54% response rate) were received. The analysis revealed that 44 libraries had at least one PC with only nine of such centres having at least one CDROM workstation. There are 62 copies of 43 CD titles in Nigeria. Information on the discs is classified as bibliographic, full text, statistical, or general information. The subjects they cover in descending numeric order are agriculture, general reference, medicine, science and technology, social sciences, and education. Areas of applications include information retrieval, bibliographic compilations, current awareness services, library acquisition work, and downloading and uploading to local online databases. In general, CD use was minimal in most libraries as opposed to information centres where CD applications were well used by patrons, especially where the mass media was employed to advertise them. Most libraries funded their CD projects with their local budgets. The most frequently used computers are IBM or compatibles. Recommendations are also outlined.

This paper aims to investigate the impact of integrating Sustainable Enterprise Resource Planning (S-ERP) systems and lean manufacturing (LM) practices on sustainability performance, especially in Egypt as an emerging country.

The authors carried out an experimental study with a sample of 144 professional accountants of MPA, MBA and DBA students at two of the top universities in Egypt.

The results provide significant evidence that the integration of S-ERP systems and LM practices implementation improve sustainability performance. However, there is no significant evidence that S-ERP adoption contributes to the success of LM practices implementation.

Because of the chosen research approach, this study is limited to use of a laboratory experiment design. Empirical evidence based on quasi experiments on a field setting would add value to the current literature.

Findings provide practical insights for the manufacturing sector managers into the benefits of integrating S-ERP systems and LM practices for sustainability performance improvement (e.g. reducing cost and waste, increasing operational efficiency). For ERP vendors, findings highlight how ERP vendors introduce “enablers” that incorporate LM best practices into their ERP systems and also how those vendors conform to the software sustainability criteria in the design of ERP applications.

Contrary to previous studies that addressed the individual impact of S-ERP systems and LM practices on performance, this paper experimentally gives an indication of the impact of concurrent implementation of S-ERP and LM practices on sustainability performance, especially in developing countries.

1.1. Libraries and CDROMs: a survey CDROMs are now in widespread use in libraries, especially academic libraries. CDROMs have yet to achieve the fabulous market success once predicted for them, but their number has grown significantly in the context of electronic publishing. Twenty percent of the world's electronic products are, in fact, in the CDROM medium. Moving on to the type of information recorded, the annual growth rate of fulltext databases increased from 58% in 1985 to 490% in 1993 precisely because of the increased availability of this particular storage medium (Williams 1994).

Undergraduates use electronic library resources for academic activities. However, literature has revealed that undergraduates’ use of electronic library resources is low in Nigeria owing to attitude, computer literacy and information retrieval skills, while little attention was given to computer self-efficacy. This paper aims to examine computer self-efficacy as a predictor of undergraduates’ use of electronic library resources in federal universities in south-west Nigeria.

The descriptive survey research design was adopted. Multi-stage sampling method was used to select 1,526 undergraduates from the population size of 30,516 from six federal universities in south-west Nigeria in four faculties (Arts, Engineering/ Technology, Science and Social sciences) and three departments from each of the faculties (English, History and Philosophy; Electrical and Electronics Engineering, Civil Engineering and Mechanical Engineering: Economics, Sociology and Psychology). Data were collected using a questionnaire and were analysed using descriptive statistics, mean and standard deviation, Pearson’s Product Moment Correlation, hierarchical and regression analyses at 0.05 level of significance.

There was a significant relationship between computer self-efficacy and use of electronic library resources (r = 0.13, p < 0.05). The result of the analysis showed that computer self-efficacy influenced undergraduates’ use of electronic library resources in federal universities in south-west Nigeria.

The data for the research were obtained from undergraduates in the selected faculties in the six federal universities except for two faculties which did not have some departments that were common to the selected faculties.

The findings indicated that computer self-efficacy improves the use of electronic library resources for academic purposes. It therefore encourages the library management to provide the necessary support and training for the undergraduates to acquire the technical skills required for the acquisition of computer self-efficacy. This has greater influence on undergraduates’ ability to use the computer maximally to access electronic library resources for academic purposes.

It will improve the undergraduates’ use of electronic library resources for academic purposes. This implies that the undergraduates will have access to information around the world that could be useful for development in and around their locality which will become easily accessible. Also, in this era of computer, it will encourage reading culture among undergraduates. This could inform policymakers on the need to provide more electronic library resources for libraries.

The study provides original data on computer self-efficacy as a predictor of undergraduates’ use of electronic library resources in federal universities in south-west Nigeria. This can provide valuable indicator for library managements considering enhanced utilisation of electronic library resources.

Nigeria has set up an e‐government initiative termed the “National e‐Government Strategy” (NeGSt) for the purpose of using ICT infrastructure to enhance public services. It was expected that e‐government would enable the Nigerian government at all levels to render efficiencies in the public sector, ensure higher productivity and economic growth, foster national competitiveness and lead to the attainment of the vision 20‐2020. Regrettably, the e‐services envisaged seem not to be impacting much on public service delivery in the country. The aim of this paper is to examine the benefits and the status of e‐government in Nigeria, the barriers to the accomplishment of the goal, and some ways out.

A total of ten federal government ministries in Nigeria that have an official website were sampled. The study population was 100 randomly drawn employees in the ministries, and a structured questionnaire and oral interviews were used. Data were analyzed using frequency tables, simple percentages, and bar charts.

The study finds that e‐government would provide faster access to government information, lower administrative costs, increase transparency in government ministries, and reduce bribery and corruption, among others. These opportunities are threatened by low bandwidth and internet penetration, inadequate ICT infrastructure and technicians, incessant power outages, technological obsolescence, and other barriers. The Nigerian government should carry out a SWOT analysis of the e‐government project in the country, strengthen the e‐government infrastructure and ensure steady power supply before embarking on the e‐government project again.

This paper exposes the challenges and strategies for the e‐government initiative in Nigeria. It will help leaders to see areas of weakness and the need to re‐strategize. The paper serves as a beacon for further research and discussion on e‐government and online public services in developing countries.

This paper exposes the challenges and strategies for the e‐government initiative in Nigeria and suggests some measures for e‐government to develop and to improve.

The purpose of this paper is to examine the barriers to effective resource sharing among academic libraries in Nigeria.

Professional librarians from six randomly selected federal university libraries representing the six geopolitical zones in Nigeria were surveyed using a descriptive survey research design. Questionnaires were sent to 124 librarians; 85 were returned and found to be usable, for a response rate of 68.5 per cent.

The study revealed that the prospect for resource sharing among university libraries in Nigeria is high. However, factors that hinder effective resource sharing include inadequate funding, a dearth of skilled librarians, power outages, an absence of web‐accessible OPACs, uneven development of libraries, and slow progress of library automation. It is recommended that each university library have a specific annual budget allocation for ICT development and maintenance and for training of librarians to pilot resource sharing projects.

This paper presents resource‐sharing challenges facing academic libraries in Nigeria. It encourages information professionals to embark on capacity building for effective resource sharing. This paper was prepared for the 12th Interlending and Document Supply Conference, held in September 2011.

To provide coverage and insights about the annual meeting of the AAAS where this year's theme was “Science and Technology for Sustainable Well‐Being.”

Environmental scan of annual national meeting. Of particular interest due to the range of backgrounds different attendees from all avenues of the scientific community.

Sustainable well being has wide applications in different arenas but the informatics component was not as strong as at past conferences.

Much of the conference focused on intersections of theory and application and new ways of responding to sustainability. Particularly strong in the physical sciences.

Provides information of value to information professionals.

The purpose of this study is to compare the use of electronic resources (e-resources) by undergraduate students in library and information science (LIS) and computer science in two Nigerian universities.

This study adopted a comparative method. The questionnaire was designed to elicit data from 680 undergraduate students in two universities. Simple percentages and chi square (χ²) statistical tool were used to analyse and test the hypotheses. The results are presented in tables and charts.

The findings show that the undergraduate students use some of the e-resources and do not use others probably because of lack of awareness or skills to effectively use the e-resources. Overall, almost half of the undergraduate students rated their skills to use e-resources to be high. It also emerged that there is significant difference between LIS students and computer science students use of e-resources.

The findings of this study on e-resources and their use by different subject areas in the university will establish an important foundation for selecting and providing e-resources and services. Such a foundation allows for the development of both useful theory and practical application.

The study reported findings on e-resources used particularly by different user groups in universities in Nigeria. The study will add to the body of knowledge on use of e-resources in Nigeria.

The purpose of the article is to investigate readiness of academic librarians toward the use of robotic technologies in Nigerian university libraries. The article provides further insights on the following areas: •What are the levels of readiness of university libraries in Nigeria towards robotic technologies in terms of digital infrastructure, policy framework and human development for the adoption and use of robotics in the libraries? •What services are available in the university libraries that can be handled by robotic technologies? •Are academic librarians aware of the potential benefits of robotics in library operations? •What are the potential challenges that university libraries may face in the adoption and use of robotic technologies?

The study is a survey research anchored on positivism paradigm. The questionnaire was used as data collection instrument. Furthermore, 100 academic librarians were selected from the ten purposively selected ten universities. Snowballing sample technique was used to select ten academic librarians from each of the university libraries.

The findings of the study revealed that the readiness of university libraries in Nigeria towards the adoption and use of robotic technologies in Nigeria is nothing to write home about. It indicates that university libraries in the country are not ready to adopt the use of this technology despite the high benefits they have to offer in library operations.

The limitations of the study lay on the fact that very few librarians from each of the selected university libraries were selected; and at the same time, it covers only ten university libraries in the country.

The study is very important to university library management on the necessary steps that need to be taken for the effective adoption of robotic technologies. This research can be a guide to them. In addition, the empirical analysis of the study contributes to social informatics development in Nigeria.

The purpose of this paper is to study the effects of particle size distribution, component ratio, particle packing arrangement, and chemical constitution on the laser sintering behaviour of blended hypoeutectic Al‐Si powders.

A range of bimodal and trimodal powder blends were created through mixing Al‐12Si and pure aluminium powder. The powder blends were then processed using selective laser sintering to investigate the effect of alloy composition, powder particle size and bed density on densification and microstructural evolution.

For all of the powder blends the sintered density increases with the specific laser energy input until a saturation level is reached. Beyond this saturation level no further increase in sintered density is obtained for an increase in specific laser energy input. However, the peak density achieved for a given blend varied significantly with the chemical constitution of the alloy, peaking at approximately 9 wt% Si. The tap density of the raw powder mixture (assumed to be representative of bed density) was also a significant factor.

This is the first study to consider the usefulness of silicon as an alloying element in aluminium alloys to be processed by selective laser sintering. In addition the paper outlines the key factors in optimising processing parameters and powder properties in order to attain sound sinterability for direct laser sintered parts.
