This conference marks the first of its kind in the annals of DLIS.
The theme of the conference “Managing Information in the Digital Era” derives from the revolutionalising impact of Information and Communication Technology (ICT) across the globe resulting in tremendous changes in all sections of the society. It has also made significant impacts on the global knowledge economy, which reduced the gap between the information rich and poor. Also, libraries/information and knowledge management centres exploit new technologies for information processing, storage and retrieval, knowledge storage and dissemination, creating collaborative tools, designing user-friendly interfaces to provide customized services to end users. These new tools facilitate global partnership, networking of institutions for knowledge creation, preservation and sharing. Libraries and knowledge centres are at the forefront of experimenting and implementing new technologies for providing information to diverse groups of users.
The conference has been part of DLIS response to the need for information professionals to constantly update and upgrade their skills to manage knowledge resources in rapidly changing environments and contexts digital technologies. The conference has been an international forum for the presentation of technological advances and research results in the fields of Library science, Information science, Information systems and Information Technology. Participants include leading academics, researchers, scientists and professionals from different parts of the world.
The papers in this proceedings have been carefully selected and they cover a wide range of sub-themes including: Digital divide, Knowledge Management (KM), Digital Library, records and information management, information literacy standards and models, electronic commerce, and Information and information technology policy issues.
All papers were reviewed blindly (that is, with author information removed) by between 2 and 3 reviewers. The reviewers did not know the identity of the authors nor the authors of the reviewers. Reviewers were matched to papers based on a formula to minimize the distance between reviewers’ expertise and interest and the topics covered in the paper. No reviewer was required to review more than 2 papers. In all, the review process used the services of 22 reviewers. Reviewers were instructed to mentor the authors by providing feedback on how to improve the submission and to determine whether or not a paper is fit for presentation at the conference or not.
The authors of all papers, whether accepted or not, were provided with the reviewers’ feedback, as part of the process of mentoring authors. Authors of accepted papers were asked to revise their submissions to address the issues raised in the reviews.
We believe that the papers in this book represent a great contribution to scholarship particularly in the field of library and information science.

The aim of writing this book is to impart in students the knowledge and skills
needed in understanding issues relating to database management in an
information retrieval environment. Students will develop their information
skills to a reasonable extent. I have used very simple language and expressions
to explain technical concepts, so be rest assured that you will understand the
different topics treated in the different chapters. I have tried very much to keep
the content in this book up- to-date and relevant so that the skills and
knowledge that you acquire would be useful both in the short and long run.
Now let me give a preview of the topics treated in each chapter of this book.
Chapter one gives a general introduction to the concept data, information and
knowledge. It also explains the differences between knowledge and
information management as well as describing what data mining and data
warehousing is and how they work in diverse information management
environments. Chapter two presents metadata and data dictionary pointing out
their importance in records and information management. The concept of
databases is the main subject of chapter three and issues explained in detail
include the properties of databases, types of databases and the reasons why
organizations might adopt the database approach to information management.
The chapter also sheds light on the development of databases in an
information retrieval environment.
ii
Chapters four and five examine file organization and database management
systems (DBMS) respectively which are major issues in database and
information retrieval. Data modelling and models is the subject of chapter six
followed by database normalization in chapter seven. The design of databases
using Entity-Relationship (ER) modelling was presented in chapter eight. The
chapter explained conceptual data modelling, and described the procedures for
developing Entity-Relationship Diagrams (ERDs). Chapter nine dwells on
Structured Query Language (SQL) as one of the modern day languages used
in managing databases. The chapter explains the functions of SQL both as a
data definition language and data manipulation language.
Chapter ten introduces the concept of information retrieval by defining what is
Information retrieval and distinguishing it from data retrieval. The chapter
also describes some tasks of users of Information retrieval, activities involved
in the Information retrieval process and the models of Information Retrieval.
Chapter eleven expatiated further on information retrieval by describing
several database search tools and strategies which users can use to get the
pieces of information they are looking for from any information retrieval
system. The diverse search facilities offered by most retrieval systems
including: Boolean query formulation, proximity searching, range searching,
truncation searching and wildcards were adequately covered.
Due to the increasing importance of the Web in searching and retrieving
information by people all the world over today, chapter twelve presents the
issues relating to Internet and Information retrieval. Apart from giving an
overview of the Internet and its services and tools, the chapter also explains
and describes how to conduct searches on the Internet using different search
methods and tools. Information retrieval evaluation is the subject covered in
iii
chapter thirteen where issues relating to using effectiveness and efficiency
measures for retrieval evaluation were espoused.
Each chapter also has in-text questions that you can use to assess yourself as
you move from chapter to chapter. There are also self assessment activities
comprising a series of study questions at the end of each chapter to make you
review what you have learnt so that you can reflect on the topics discussed
throughout the different chapters. In addition, each chapter has a glossary of
terms that explains some technical terminologies that you may not yet be
familiar with. Please be encouraged to improve on your knowledge gained
from this book by complementing it with materials suggested to you under
further reading in each chapter.
Overall, on successful completion of this book, you shall be able to:
x Distinguish among data, information and knowledge
x Define what metadata and data dictionary are and explain their
application in information management
x Describe database management systems (DBMS) and its features and
capabilities in database management
x Explain the issues relating to the development of databases in an
information retrieval environment
x Create normalized databases using structured query language (SQL)
x Construct entity-relationship diagrams (ERDs)

The book is primarily written in response to the dearth of quality texts on Information Technology (IT) tailored to serve the needs of on-site and distance learners. The aim of the book is to introduce tertiary level students to the fundamentals of IT tools and their applications in very simple and lucid language. The highlights of its content include: vivid description of basic ICT concepts - computer hardware and software (particularly those for performing data processing tasks as word processing, spreadsheet, database management and presentations), description of web browsing and communication, social networking, as well as the social and health impacts of ICT use. An expose on legal and security issues relating to ICT use and the digital divide question was also aptly treated.
The presentation of concepts is simplified both by the use of non-technical language and illustrations to aid comprehension. Each chapter contains an overview, objectives, topics covered, in- and end of-chapter self-assessment activities and a glossary of terms. The book is thus suitable for undergraduate and postgraduate students in communication, computer science, library and information science, information and knowledge management in universities and polytechnics where a basic grounding of information technology tools and applications is taught.

Without its incorporation into the information age, there is little chance for countries or regions to develop. More and more concern is being shown about the impact of those left on the other side of the digital divide—the division between the information “haves” and “have nots.” Most women within developing countries are in the deepest part of the divide, further removed from the information age than the men whose poverty they share. If access to and use of these technologies is directly linked to social and economic development, then it is imperative to ensure that women in developing countries understand the significance of these technologies and use them. If not, they will become further marginalized from the mainstream of their countries and of the world. It is essential that gender issues be considered early in the process of the introdu...

Data obtained from the electoral body were analysed using frequency distribution and Spearman Rank Correlation tests at 0.05 level of significance. Findings revealed that the second digits distributions of the vote counts for the two major political parties, registered voters and total vote counts in both elections do not conform to the distributional pattern predicted by Benford's Law. The study recommends that stakeholders should aim for an electoral reform that allows the use of forensic analysis of electoral data in Nigeria.

The influence of the five constructs: system and service quality, perceived risk, organizational reputation, perceived ease of use and perceived usefulness on attitude was used to determine users' intention to use online banking. Survey research design was adopted. Six hundred online banking users in five banks were selected using stratified random sampling. Data were collected using a structured questionnaire. Frequency and percentage distributions and multiple regression were analytical techniques used. The research hypotheses were tested at 0.05% level of significance. Findings revealed that the constructs -system and service quality (β .127, p .003), perceived risk (β .122, p .000), organizational reputation (β .167, p .000), perceived ease of use (β.206, p .000) and perceived usefulness (β .119, p .002) -, have a significant influence on the attitude of online banking users. Also attitude had a significant impact on the Intention to use online banking. System and service quality had the lowest weight of impact on attitude while perceived ease of use had the highest. It was concluded that individual, organizational and systems factors influence attitude toward continued use of banking. Banks should make the interface of online banking systems as friendly as possible and adopt the latest technologies that are standardized for effective and efficient internet banking transactions.

The study analysed socio-demographic differences in access and use of ICTs using Sen's capability approach. Survey research approach was adopted. The locations were a rural and an urban community. The population of the study comprised 500 respondents selected from the two locations. The two locations were intentionally selected with a view to ensuring rural versus urban data comparisons. A structured questionnaire was the data collection instrument adopted. Chi-square analysis was used to determine the significant factors affecting people's access and use of ICTs. The result was cross tabulated against the socio-demographic characteristics of the people in the two locations. Findings revealed that there was a gender digital divide among the respondents in the two locations as well as rural-urban divide. It was also found that both male and female respondents in the two locations had access to all the ICT facilities surveyed, some in their homes and others in public places such as church, cyber café, working places, friend's place, etc. However, most of the respondents in the rural community were reported to be able to use landline telephones more than cell phones. In the two locations, the respondents were capable of using radio and television very well. Female respondents in both locations were able to use landline telephones more than their male counterparts but the males were capable of using other facilities more than the female respondents. This was chiefly due to the fact that the male respondents in the two locations were more educated than the females. The young set of respondents was also capable of using ICTs more than the older people. Based on the findings, it was recommended that the government need to evolve policies aimed at bridging the digital divide particularly increasing ICT penetration in both rural and urban areas.

A structured questionnaire was used to collect data from 213 lecturers across the seven faculties and one institute at the National University of Lesotho (NUL). Cronbach's alpha reliability coefficient was used to determine the internal consistency of the instrument; the reliability of the multiple item scales ranged between 0.71 and 0.97. Collected data were first structured into grouped frequency distributions, and stepwise multiple regressions were used to test the five hypotheses formulated. At 0.05 level of significance, the attributes relative advantage, complexity, and observability were found to have a positive influence on attitude of lecturers toward using ICTs, with observability having the highest influence. To enhance widespread use of ICTs, it is recommended that NUL's administration organize relevant training and deploy user-friendly ICTs.

Specifically, it investigated the relationship between the salient beliefs affecting the knowledge sharing attitude of lawyers’, and applied a modified version of the Theory of Reasoned Action (TRA) in the knowledge sharing context, to predict how these factors affect their knowledge sharing behaviour.Method: A field survey of 273 lawyers was carried out, using questionnaire for data collection. Collected data on all variables were structured into grouped frequency distributions. Principal Component Factor Analysis was applied to reduce the constructs and Simple Regression was applied to test the hypotheses. These were tested at 0.05% level of significance.Results: Results showed that expected associations and contributions were the major determinants of lawyers’ attitudes towards knowledge sharing. Expected reward was not significantl...

It particularly examined the availability of ICT infrastructures, ICT adoption factors and the uses to which ICTs are put in the schools. The study also identified the effects and challenges faced by private and public schools in their use of ICT. The study adopted a descriptive survey design. A purposive sampling technique was adopted for selecting 40 schools (20 public and 20 private) from seven local governments in the 3 senatorial districts in Kwara State. Questionnaire was the main data collection instrument used. Descriptive statistics such as frequency and percentage distributions were the analytical tools adopted. Findings revealed that private secondary schools have and use ICT more than their public school counterparts in their operations but computers was the only ICT facility common in the public schools. Also, the use of Computer Aided Instruction software was not widespread in the public schools. Findings equally revealed that private secondary schools increase their ICT use by buying more ICT equipment and permitting free access to them unlike their public school counterparts that rely solely on the government for the supply of ICT equipment. Constraints such as erratic power supply, high cost of ICT facilities, improper training of ICT personnel among others were identified as the factors militating against the adoption and ICT use in the schools. Based on these findings recommendations were made. The Information Technologist Vol. 5 (1) 2008: pp. 52-73

The behaviours were information anxiety, computer phobia, obsessive computing, and computer work stress. Validated scales were designed to measure these behaviours as dependent variables, as well as computing expertise, self-esteem, locus of control, personality type, age, sex, occupation and discipline of respondents, as independent variables. Models relating to these variables were proposed, and multiple regression analyses were performed to evaluate the models. Self-esteem, personality type, age and sex correlated in various ways with information anxiety, computer phobia and work-stress.

The cluster sampling technique was used to select 160 traditional medical practitioners from the study population. Data were collected using an interviewer-administered, self-constructed structured-questionnaire. Frequency and percentage distributions were employed for data analysis. Analysis revealed that traditional medical practice in the study area was maledominated and majority of the traditional medical practitioners seek information from informal sources mostly from colleagues within the same professional association. Knowledge of traditional medical practice was revealed to be orally preserved and transmitted by word of mouth from generation to generation and the level of integration with orthodox medicine was found to be very low. The low level of education of the traditional medical practitioners denied them access to knowledge that could improve and make their services in the treatment/management of sickle cell anemia more relevant to the Nigerian society. It is recommended that proper regulation, standardization and increased involvement of government organs in the field of traditional medicine should be ensured. There is a need to bring the traditional medical practitioners into the mainstream by providing them with proper training, facilities and backup for referral.

Specifically, it investigated the relationship between the salient beliefs affecting the knowledge sharing attitude of lawyers’, and applied a modified version of the Theory of Reasoned Action (TRA) in the knowledge sharing context, to predict how these factors affect their knowledge sharing behaviour.Method: A field survey of 273 lawyers was carried out, using questionnaire for data collection. Collected data on all variables were structured into grouped frequency distributions. Principal Component Factor Analysis was applied to reduce the constructs and Simple Regression was applied to test the hypotheses. These were tested at 0.05% level of significance.Results: Results showed that expected associations and contributions were the major determinants of lawyers’ attitudes towards knowledge sharing. Expected reward was not significantl...

It particularly examined the availability of ICT infrastructures, ICT adoption factors and the uses to which ICTs are put in the schools. The study also identified the effects and challenges faced by private and public schools in their use of ICT. The study adopted a descriptive survey design. A purposive sampling technique was adopted for selecting 40 schools (20 public and 20 private) from seven local governments in the 3 senatorial districts in Kwara State. Questionnaire was the main data collection instrument used. Descriptive statistics such as frequency and percentage distributions were the analytical tools adopted. Findings revealed that private secondary schools have and use ICT more than their public school counterparts in their operations but computers was the only ICT facility common in the public schools. Also, the use of Computer Aided Instruction software was not widespread in the public schools. Findings equally revealed that private secondary schools increase their ICT use by buying more ICT equipment and permitting free access to them unlike their public school counterparts that rely solely on the government for the supply of ICT equipment. Constraints such as erratic power supply, high cost of ICT facilities, improper training of ICT personnel among others were identified as the factors militating against the adoption and ICT use in the schools. Based on these findings recommendations were made. The Information Technologist Vol. 5 (1) 2008: pp. 52-73

The behaviours were information anxiety, computer phobia, obsessive computing, and computer work stress. Validated scales were designed to measure these behaviours as dependent variables, as well as computing expertise, self-esteem, locus of control, personality type, age, sex, occupation and discipline of respondents, as independent variables. Models relating to these variables were proposed, and multiple regression analyses were performed to evaluate the models. Self-esteem, personality type, age and sex correlated in various ways with information anxiety, computer phobia and work-stress.

The cluster sampling technique was used to select 160 traditional medical practitioners from the study population. Data were collected using an interviewer-administered, self-constructed structured-questionnaire. Frequency and percentage distributions were employed for data analysis. Analysis revealed that traditional medical practice in the study area was maledominated and majority of the traditional medical practitioners seek information from informal sources mostly from colleagues within the same professional association. Knowledge of traditional medical practice was revealed to be orally preserved and transmitted by word of mouth from generation to generation and the level of integration with orthodox medicine was found to be very low. The low level of education of the traditional medical practitioners denied them access to knowledge that could improve and make their services in the treatment/management of sickle cell anemia more relevant to the Nigerian society. It is recommended that proper regulation, standardization and increased involvement of government organs in the field of traditional medicine should be ensured. There is a need to bring the traditional medical practitioners into the mainstream by providing them with proper training, facilities and backup for referral.

Data obtained from the electoral body were analysed using frequency distribution and Spearman Rank Correlation tests at 0.05 level of significance. Findings revealed that the second digits distributions of the vote counts for the two major political parties, registered voters and total vote counts in both elections do not conform to the distributional pattern predicted by Benford's Law. The study recommends that stakeholders should aim for an electoral reform that allows the use of forensic analysis of electoral data in Nigeria.

The study was a sample survey of mobile phone users. Data was collected with a self structured questionnaire from 367 users using convenience sampling technique and was analyzed using inferential statistical approach. The result revealed that while mobile users between ages 19-24 (p=0.021) and ages 25-30 (p=0.028) were influenced by price, ages 25-30 (p=0.015) proved additionally sensitive to service quality. The occupation category showed that student (p=0.031) mobile users were significantly influenced by promotional offers. Mobile users whose income were below N20,000 (p=0.042) and between N51,000-N100,000 (p= 0.09) and whose expenditure on mobile services were amid N2,001-N3,000 (p=0.03) and N4,001-N5000 (p=0.03) were both influenced by operators brand image. Yet, religion (Christian, p=0.035 , Islam, p=0.41) did ...

The theme of the conference “Managing Information in the Digital Era” derives from the revolutionalising impact of Information and Communication Technology (ICT) across the globe resulting in tremendous changes in all sections of the society. It has also made significant impacts on the global knowledge economy, which reduced the gap between the information rich and poor. Also, libraries/information and knowledge management centres exploit new technologies for information processing, storage and retrieval, knowledge storage and dissemination, creating collaborative tools, designing user-friendly interfaces to provide customized services to end users. These new tools facilitate global partnership, networking of institutions for knowledge creation, preservation and sharing. Libraries and knowledge centres are at the forefront of experimenting and implementing new technologies for providing information to diverse groups of users.
The conference has been part of DLIS response to the need for information professionals to constantly update and upgrade their skills to manage knowledge resources in rapidly changing environments and contexts digital technologies. The conference has been an international forum for the presentation of technological advances and research results in the fields of Library science, Information science, Information systems and Information Technology. Participants include leading academics, researchers, scientists and professionals from different parts of the world.
The papers in this proceedings have been carefully selected and they cover a wide range of sub-themes including: Digital divide, Knowledge Management (KM), Digital Library, records and information management, information literacy standards and models, electronic commerce, and Information and information technology policy issues.
All papers were reviewed blindly (that is, with author information removed) by between 2 and 3 reviewers. The reviewers did not know the identity of the authors nor the authors of the reviewers. Reviewers were matched to papers based on a formula to minimize the distance between reviewers’ expertise and interest and the topics covered in the paper. No reviewer was required to review more than 2 papers. In all, the review process used the services of 22 reviewers. Reviewers were instructed to mentor the authors by providing feedback on how to improve the submission and to determine whether or not a paper is fit for presentation at the conference or not.
The authors of all papers, whether accepted or not, were provided with the reviewers’ feedback, as part of the process of mentoring authors. Authors of accepted papers were asked to revise their submissions to address the issues raised in the reviews.
We believe that the papers in this book represent a great contribution to scholarship particularly in the field of library and information science.

The aim of writing this book is to impart in students the knowledge and skills
needed in understanding issues relating to database management in an
information retrieval environment. Students will develop their information
skills to a reasonable extent. I have used very simple language and expressions
to explain technical concepts, so be rest assured that you will understand the
different topics treated in the different chapters. I have tried very much to keep
the content in this book up- to-date and relevant so that the skills and
knowledge that you acquire would be useful both in the short and long run.
Now let me give a preview of the topics treated in each chapter of this book.
Chapter one gives a general introduction to the concept data, information and
knowledge. It also explains the differences between knowledge and
information management as well as describing what data mining and data
warehousing is and how they work in diverse information management
environments. Chapter two presents metadata and data dictionary pointing out
their importance in records and information management. The concept of
databases is the main subject of chapter three and issues explained in detail
include the properties of databases, types of databases and the reasons why
organizations might adopt the database approach to information management.
The chapter also sheds light on the development of databases in an
information retrieval environment.
ii
Chapters four and five examine file organization and database management
systems (DBMS) respectively which are major issues in database and
information retrieval. Data modelling and models is the subject of chapter six
followed by database normalization in chapter seven. The design of databases
using Entity-Relationship (ER) modelling was presented in chapter eight. The
chapter explained conceptual data modelling, and described the procedures for
developing Entity-Relationship Diagrams (ERDs). Chapter nine dwells on
Structured Query Language (SQL) as one of the modern day languages used
in managing databases. The chapter explains the functions of SQL both as a
data definition language and data manipulation language.
Chapter ten introduces the concept of information retrieval by defining what is
Information retrieval and distinguishing it from data retrieval. The chapter
also describes some tasks of users of Information retrieval, activities involved
in the Information retrieval process and the models of Information Retrieval.
Chapter eleven expatiated further on information retrieval by describing
several database search tools and strategies which users can use to get the
pieces of information they are looking for from any information retrieval
system. The diverse search facilities offered by most retrieval systems
including: Boolean query formulation, proximity searching, range searching,
truncation searching and wildcards were adequately covered.
Due to the increasing importance of the Web in searching and retrieving
information by people all the world over today, chapter twelve presents the
issues relating to Internet and Information retrieval. Apart from giving an
overview of the Internet and its services and tools, the chapter also explains
and describes how to conduct searches on the Internet using different search
methods and tools. Information retrieval evaluation is the subject covered in
iii
chapter thirteen where issues relating to using effectiveness and efficiency
measures for retrieval evaluation were espoused.
Each chapter also has in-text questions that you can use to assess yourself as
you move from chapter to chapter. There are also self assessment activities
comprising a series of study questions at the end of each chapter to make you
review what you have learnt so that you can reflect on the topics discussed
throughout the different chapters. In addition, each chapter has a glossary of
terms that explains some technical terminologies that you may not yet be
familiar with. Please be encouraged to improve on your knowledge gained
from this book by complementing it with materials suggested to you under
further reading in each chapter.
Overall, on successful completion of this book, you shall be able to:
x Distinguish among data, information and knowledge
x Define what metadata and data dictionary are and explain their
application in information management
x Describe database management systems (DBMS) and its features and
capabilities in database management
x Explain the issues relating to the development of databases in an
information retrieval environment
x Create normalized databases using structured query language (SQL)
x Construct entity-relationship diagrams (ERDs)
x Conduct searches on the Internet using different search techniques
x Download search outputs from the Web, and
x Evaluate retrieved items from the Internet
"
The presentation of concepts is simplified both by the use of non-technical language and illustrations to aid comprehension. Each chapter contains an overview, objectives, topics covered, in- and end of-chapter self-assessment activities and a glossary of terms. The book is thus suitable for undergraduate and postgraduate students in communication, computer science, library and information science, information and knowledge management in universities and polytechnics where a basic grounding of information technology tools and applications is taught.
