The study investigated undergraduate’s awareness, utilization and satisfaction with online public access catalogue (OPAC) in selected University libraries in Nasarawa State, Nigeria. Four (4) objectives with corresponding research questions guided the study. The study adopted survey research design. The population of the study was 7,233 registered library users (undergraduates) in two (2) public universities in Nasarawa State, namely Federal University Lafia (FULAFIA) and Nasarawa State University, Keffi (NSUK). The sample size for the study was 379 drawn using Taro-Yemene’s formula for sample size determination. Proportionate stratified random sampling technique was used to select the sample of respondents from the two (2) universities under study (i.e.) FULAFIA with 150 and NSUK, 299 respectively. Questionnaire was used as instrument for data collection. A total of 379 questionnaire were distributed and 362 retrieved for analysis representing a percentage of 95.5%. Data was analyzed using frequency counts; mean scores and standard deviation. Findings of the study revealed that, undergraduates were highly aware of Online Public Access Catalogue in selected University Libraries in Nasarawa State. The finding also revealed, undergraduates in selected university libraries in Nasarawa State utilized OPAC to a little extent and students were not satisfied with the use of OPAC, hence their extent of satisfaction derived from the use of OPAC was little extent. Findings further revealed factors affecting use of OPAC by undergraduates in selected university libraries to include: library guide to explain how to use the OPAC is not available, unstable power supply, library staff not friendly, network/server problems, lack of computer systems, among others. Finally, conclusion and recommendations were made based on the findings of the study.

Disaster Training

Purpose The purpose of this paper is to identify the challenges affecting disaster training in federal and state university libraries in Southwest Nigeria with a view to finding ways of overcoming them. Design/methodology/approach Having adopted the descriptive research design, 14 university libraries (seven each of federal and state) were selected from the Southwest geo-political zone of Nigeria. The total enumeration sampling technique was employed. Questionnaire and interview methods were used for data collection. The three research questions that guided the study were analyzed using descriptive statistics such as mean, standard deviation and ranking. Judgments were drawn using real limit of numbers and 2.50 as criterion mean. Findings Results emanated from the study showed that university libraries in the studied region are more equipped to fight fire disaster than any other emergency which is why fire drills and exercises are the prevailing disaster training received by library staff. It was also found that inadequate disaster facilities and equipment as well as poor funding were the greatest challenges confronting disaster training. The provision of adequate disaster facilities and equipment with the constitution of disaster prevention and response team was found as the most potent strategy for addressing the identified challenges. Originality/value The study lends strong empirical evidence for the underlining factors affecting disaster training in federal and state university libraries as well as academic libraries in general. The strategies for addressing the identified challenges are of more significance.

Electronic books (e-books) are vital information resources in every university library as they are utilised by users in search of information for conducting research activities, teaching, learning and assignment. This study investigated the relationship between utilisation of e-books and users’ satisfaction in university libraries in North East Zone, Nigeria. Correlational research method was used. The population of the study comprised of five thousand three hundred and seventy nine (5,379) registered library users spread across the five sampled university libraries under study. Stratified random sampling technique was used in drawing the samples and the sample size for this study was one thousand three hundred and seventy two (1,372) registered library users drawn using Krejcie and Morgan (2006) table. Questionnaire was used as the research instrument. Data collected were analysed using descriptive statistics to answer the two research questions, while, inferential statistics of Pearson Product Moment Correlation Coefficient (PPMC) was used to test the formulated null hypothesis at 0.05 level of significance. Findings from the study revealed that users’ utilisation of e-books and users’ satisfaction with utilisation of e-books for research, learning, assignment and information in university libraries in North East Nigeria were generally moderate. The study also established that there was significant relationship between utilisation of e-books and users’ satisfaction in university libraries in North East Zone, Nigeria. The study recommended teaching of information literacy for library users, acquisition of adequate and relevant e-books in the university libraries as well as discouraging users from using information obtained from online sources such as Google and other search engines as they are mostly ineffective for their research activities, teaching, learning and assignment.

Surrogate models, capable of emulating the robust first principle based models, facilitate the online implementation of computationally expensive industrial process optimization. However, the heuristic estimation of parameters governing the surrogate building often renders them erroneous or under-trained. Current work aims at presenting a novel parameter free surrogate building approach, specifically focusing on Artificial Neural Networks. The proposed algorithm implements Sobol sampling plan and intelligently designs the configuration of network with simultaneous estimation of optimal transfer function and training sample size to prevent overfitting and enabling maximum prediction accuracy. A novel Sample Size Determination algorithm based on a potential concept of hypercube sampling technique adds to the speed of surrogate building algorithm, thereby assuring faster convergence. Surrogates models for a highly nonlinear industrial sintering process constructed using the novel algorithm resulted in 7 times faster optimization.

Research is aimed at the discovery and interpretation of facts, revision of accepted theories or laws in the light of new facts or practical application of such new or revised theories or laws. A sample provides needed information about the population quickly. However, there is no guarantee that any sample will be precisely representative of the population from which it comes. It is cheaper to observe a part rather than the whole. This chapter is a discussion on sampling in research and it is mainly designed to equip researchers with knowledge of the general issues to consider when sampling. The purpose of sampling in research, dangers of sampling and how to minimize them, types of sampling and guides for deciding the sample size are discussed. For a clear flow of ideas, a few definitions of the terms used are given. They highlight the types and methods of sampling, sampling errors and discusses techniques of sample size determination. Different types of sampling technique, how to carry them out, and their advantages and disadvantages are also introduced.

A Review of: Cummings, J., Merrill, A., & Borrelli, S. (2010). The use of handheld mobile devices: Their impact and implications for library services. Library Hi Tech, (28)1, 22-40. https://doi.org/10.1108/07378831011026670 Abstract Objective – The authors undertook this study to understand the relatively new phenomenon of handheld computing and the use of small-screen devices among academic library users. They sought to determine if users would be inclined to search the online library catalogue on their devices and, by extension, if there would be a growing demand for small-screen compatible library services. Design – Online and paper surveys were used with both closed and open questions. Respondents included students, faculty, and staff at Washington State University (WSU). Setting – Washington State University Library, Pullman, Washington, United States of America. Subjects – The survey was open to any user of the Washington State University (Pullman) Library. The 206 respondents included 126 (61.2%) undergraduates, 26 (12.6%) graduate or professional students, 32 (15.3%) WSU employees, and 15 (7.3%) faculty members. Methods – A survey was distributed both online and on paper. The online version used Surveymonkey.com and participation was solicited through various social media. It was open for three months during the Spring semester, 2007. The paper version was distributed to all library users on two days in June 2007. Eighty-four online and 122 paper responses were received. Main Results – Most of the respondents (58.4%) who owned a personal digital assistant (PDA) or Web-enabled cell phone (WECP) indicated that they would search the library catalogue on a small-screen device. Responses to the open question “How would you use the OPAC [online public access catalogue] if it was available on a PDA or WECP?” were mixed, both positive and negative. The positive responders noted the possible time savings associated with the availability of more information on their devices. The negative responders noted the cost of data, the annoyance of public phone use, and the complex format of the current catalogue that would not transfer to a small screen. Conclusion – The authors cited the growing usage trends in handheld devices, along with the willingness of current owners to use their devices, to predict an increase in usage of small screen searching. They speculated that further research should investigate how small screens would be used and what would that experience look like, rather than if patrons would use them.

Entrepreneurial skills are a set of specific knowledge, abilities, skills, traits, motives, attitudes and values essential for the personal development and successful participation of each person in an organization. The aim of this study is to investigate the effect of entrepreneurial skills on SMEs performance among owners/managers operating registered businesses in Sabon Gari Market Kano, Nigeria. Descriptive survey research design was used while a sample size of one hundred and seventy two (172) business owners/managers were drawn through the use of Yamane (1967) formula for sample size determination out of three hundred and three (303) owners/managers operating registered businesses in Sabon Gari Market, Kano, which constituted the study population. Probability sampling technique was used which involves simple random sampling. Closed-ended questionnaire served as a data collection tool for the study and Regression analysis was used to analyse the collected data through Statistical Package for Social Science (SPSS) version 21. Face validity and reliability test (Cronbach’s Alpha) were conducted. The findings indicate that entrepreneurial skills have significant effect on SMEs performance; it also shows that significant relationship exists between entrepreneurial skills and SMEs performance. The study recommends that business owners and managers should focus on improving entrepreneurship skills in order to improve the performance of small and medium scale enterprises. Future researchers should expand the scope of the study to incorporate more organizations; again the research used only one variable, future researchers should use more variables in order to better capture the opinion of the respondents.

Background of the study: The study investigated the use and perception of Online Public Catalogue (OPAC) by users in academic libraries in Kwara State, Nigeria. Purpose: The study adopted descriptive survey research method were a total number of 203 questionnaires were distributed amongst library users in both selected academic libraries. A simple random sampling technique was used for this study. Method: The descriptive analysis was used to analyze the collected data using frequency counts and simple percentages. Findings: The study revealed that majority of the respondents is aware of the existence and availability of OPAC. Although a very small percent of respondents in Unilorin and Kwara State Polytechnic got their awareness of OPAC through the library. The study also revealed that an average percent of respondents in both institutions can make use of the library OPAC effectively. Based on user’s perception of OPAC, the findings show that majority of respondents highly acknowledge OPAC, well perceived and more preferred to card catalogue. A high percent of respondents admitted that the library OPAC enable them to locate materials quickly on the shelf. However, most of the respondents showed that they are facing some challenges which include poor network services, power failure, poor assistance from the library staff etc. Conclusion: The researchers recommend that the library should create more awareness and effective user education for students on the use of OPAC at various levels to ensure maximum utilization of the library resources.
