The purpose of this study was to evaluate the usability effectiveness of a webware for electronic theses and dissertations (ETDs) in Nigerian repositories. The webware (etdsearch.com.ng) is a web application system that curates ETDs from three sampled Federal government-owned universities. The system also links users to the repositories where the theses and dissertations are hosted.

The case study research strategy was adopted for the study. Sixty postgraduate students from three universities were randomly selected. A usability evaluation questionnaire based on the ISO 9241-11 framework was used to collect data after performing pre-defined queries/tasks based on the informational and transactional query models. The research questions were analysed using the median of the performance score (f_x) of the three universities for each item evaluated, while the Kruskall–Wallis test by ranks was used to test the null hypothesis at a 5% level of significance.

The study answered two research questions and tested two null hypotheses on the usability effectiveness of the webware based on the informational and transactional queries. The participants found the ETD search system effectively useable. In addition, there was no significant difference in the opinions of the participants.

The webware used simulated repositories as a feed bed for the ETDs in order to have control over the workability of the repositories. Thus, the results may differ slightly when “live” repositories are used.

The effectiveness of a webware that aggregates ETDs in Nigerian repositories will present libraries in Nigeria with evidence on how these systems work and can be improved upon.

There is a dearth of literature on practical usability studies of digital information systems in Nigerian libraries.

The purpose of this study is to investigate the performance of electronic theses and dissertations (ETD) initiatives in the repositories of federal government-owned universities due to the poor global visibility of ETDs from Nigeria.

An explanatory case study empirical research method was adopted for the study. Using an adapted methodology of Ghosh (2009) and multiple data gathering techniques, data was collected based on the three domains of the network of excellence on digital libraries (DELOS) digital library reference model.

The ETD initiatives in repositories of Nigerian federal universities have not made remarkable progress as digital libraries based on policy, content and system architecture. The specificity of ETDs is not clearly stated in the policies where available. The repositories housing the ETDs are also not compliant with the open archive initiative-protocol for metadata harvesting framework.

The study focussed on ETD initiatives in federal government-owned universities. Although the findings of the study are relevant to other institutions in Nigeria and sub-Saharan Africa. It cannot be used as a basis for the generalisation based on other performance metrics.

This research study concluded that electronic theses and dissertations in Nigerian institutional repositories are not well managed for effective service delivery and long-term accessibility. The ill-management of the ETD initiatives is the reason for the poor global visibility and accessibility of these research output from this part of Africa.

The study assessed ETD initiatives using constructs from a theoretical framework.

Many Higher Education Institutions (HEIs) allow students or their advisors to restrict access to theses/dissertations (TDs) by applying embargoes. This study aims to identify why Higher Education Institutions (HEIs) allow embargoes.

One hundred HEIs were randomly selected, representing seven geographic regions. The authors imported policies/guidelines for embargoing TDs into MAXQDA software and coded the qualitative data.

Among the 100 studied HEIs, 43 HEIs (43%) have policies/guidelines on the web for embargoing TDs, most of which are from North America. For the majority of HEIs, embargoes are a voluntary option for students/advisors. Content analysis of the 32 embargo policies showed that embargo reasons (18 key reasons) can be categorized into six broad themes (commercialization, publication, ethical issues, funding contracts/agreements, security and safety, and miscellaneous).

In this study, only those policies are reviewed that are available, discoverable and accessible on HEIs' websites.

Highlighting the detrimental effect of not managing stipulations towards embargoes clearly, the findings could be useful for national/institutional policymakers and administrators of research departments, academic libraries, institutional repositories and graduate offices.

This is the first study to investigate rationales for TDs embargo practices. It creates awareness of how embargoes are managed and reflected in policy. Ultimately, it recommends further interrogation on how embargoes influence the principle of openness to scholarship.

The purpose of this study is to evaluate the institutional repositories (IRs) in South India in terms of policy and procedures, technology, content and contributors, promotion and assessment and personnel.

A voluntary survey was conducted to assess IRs in South India. The questionnaire was designed according to the study framework, which comprises 64 indicators across five areas: policy and procedures, technology, content and contributors, promotion and assessment and personnel. Furthermore, all of the 23 IRs identified were monitored over one year period (from February 2018 to January 2019) to analyse the content growth.

The Research Archive of Indian Institute of Technology Hyderabad was found to provide more services to users than other South Indian IRs and it was the sole IR to embed a metadata field for author identification. Almost all the IRs were actively engaged in promotion and assessment activities. IR performance in the technology area was substandard in comparison with performance in the policy and procedures and promotion and assessment areas. For all South Indian IRs, content growth was low.

Very few in-depth studies have evaluated South Indian IRs across all five of the areas listed above and in recent years, no such comprehensive study has been conducted in India at all.

The purpose of this study is to investigate the development of institutional repositories (IR) in tertiary institution libraries in Nigeria.

The study adopted a survey research method. Online questionnaire and IR site investigation methods were used to collect data from 25 university libraries in Nigeria.

The study revealed that only 25 (14.7%) universities out of the 170 universities in Nigeria have successfully developed IRs and registered their presence in OpenDOAR. Other tertiary institutions such as Polytechnics and Colleges of Education investigated in Nigeria are yet to develop IRs. Contents such as theses and dissertations, conference proceedings and journal articles ranked highest being the most popular contents in the various IRs. The results showed that the development of IR saves space in the library, increases readership, increases access to local contents, minimizes damage to the original material, facilitates the dissemination of scholarly research and assists in globalization of Nigerian research findings. The IRs site investigation revealed that only few IRs have clearly defined access policy, content policy, submission policy and digital preservation policy. The study identified challenges such as inadequate facilities, unstable internet connectivity, lack of fund, irregular power supply, challenge of collecting materials for the IR, lack of skilled ICT personnel, copyright issues and absence of IR policies.

The results from the study will provide important data and insight into the development of institutional repositories in tertiary institution libraries in Nigeria, and generate suggestions for University Librarians, College Librarians, Polytechnic Librarians, tertiary institutions management and policy makers for developing institutional repositories in Nigeria and other developing countries.

The study investigated IR development in tertiary institutions in Nigeria. The findings will inform other tertiary institutions in developing countries that the development of IR provides an opportunity for the visibility of local contents emanating from institutions and make them see the reason to embrace this laudable development.

The necessity for continuous advancement in library education and practice requires research collaboration among library professionals. This study aims to investigate research collaboration among lecturers in the department of library and information science (LIS) and librarians in university libraries in Nigeria.

A descriptive survey research design was used for the study. The quantitative study employed a close-ended questionnaire for data collection. The study covered all the librarians in academic libraries and lecturers in the department of LIS (LIS professionals) in public universities in Ekiti, Ondo and Osun States, Nigeria. Descriptive and inferential statistics were used for data analysis. The criterion mean of 2.50–2.99 was used for the research questions.

It was found that librarians in academic libraries and lecturers in Nigeria rarely engage in research collaboration. The reasons for the research collaboration are to increase the quality of research in the library profession, make research in the library profession more in-depth and cross-fertilize ideas for generating novel insights.

It is the engagement of librarians in academic libraries and the lecturers in the LIS department in the exchange of knowledge at national and international levels through research collaboration that can enhance the quality of research that emanates from the library profession.

Promotion of the library profession requires the integrated effort of library professionals in academic libraries and lecturers in the department of LIS through research collaboration.

This study aims to adjust Thesis-type properties on Schema.org using metadata models and standards (MS) (Bibframe, electronic thesis and dissertations [ETD]-MS, Common European Research Information Format [CERIF] and Dublin Core [DC]) to enrich the Thesis-type properties for better description and processing on the Web.

This study is applied, descriptive analysis in nature and is based on content analysis in terms of method. The research population consisted of elements and attributes of the metadata model and standards (Bibframe, ETD-MS, CERIF and DC) and Thesis-type properties in the Schema.org. The data collection tool was a researcher-made checklist, and the data collection method was structured observation.

The results show that the 65 Thesis-type properties and the two levels of Thing and CreativeWork as its parents on Schema.org that corresponds to the elements and attributes of related models and standards. In addition, 12 properties are special to the Thesis type for better comprehensive description and processing, and 27 properties are added to the CreativeWork type.

Enrichment and expansion of Thesis-type properties on Schema.org is one of the practical applications of the present study, which have enabled more comprehensive description and processing and increased access points and visibility for ETDs in the environment Web and digital libraries.

This study has offered some new Thesis type properties and CreativeWork levels on Schema.org. To the best of the authors’ knowledge, this is the first time this issue is investigated.

Valuation for compensation on land and buildings compulsorily acquired for public purposes is statutory. The Land Use Act (LUA) of 1978 now cited as Laws of the Federation of Nigeria, CAP l5 LFN 2007, stipulates the use of Depreciated Replacement Cost (DRC) Method in the valuation for compensation purposes for building and installation. The purpose of this paper is to criticize the application of the DRC technique in the valuation by acquiring authority as it does not arrive at fair market value and adequate compensation in Nigeria.

The method adopted for the study was a case study of real world valuation for compensation. Data used in the study were gathered mainly from government ministries and agencies responsible for land acquisition and compensation purposes. They included the Ministry of Lands and Housing, Land Use and Allocation Committee, and Ministry of Works and Transport. Market data on rental value, sales prices and other relevant data were collected from firms of professional that deal in real property.

The result of the study reveals that valuation by acquiring authority using DRC methods as prescribed by the LUA does not reflect market value and it is inadequate to put the claimants in the position they were before the acquisition. As such, most victims expressed dissatisfaction with the amount paid to them, which sometimes result to crisis, conflict and prolonged litigation, resulting in delay in executing or abandonment of the intended project.

The study is limited to only one case study on acquisition and compensation for land and buildings with particular reference to Akwa Ibom State. This limitation does not invalidate the result as the law is applicable to the whole country.

The implication is that the LUA needs to be review to fair market value as basis of valuation and payment for site value as well as the constitution to add “adequate” to Section 44 (1a). This will reduce the incidence of many communities and land owners protest against the decision of government or its agents to acquire their land for public purposes.

The methodology meets the requirement of the law regarding compulsory land acquisition and compensation in Nigeria: The LUA of 1978. Using three scenarios: the valuation by acquiring authority, claimant’s valuers and independent valuers to illustrate the critique of the methodology, the result shows the inadequacy of compensation.

The purpose of this paper is to evaluate the practices for valuation for compensation purposes in Kenya.

A qualitative survey design was used to sample the registered valuers using questionnaire/telephone interviews, in addition to review of some policy and legal documents. Content analysis and descriptive statistics was used to analyse the data.

The study revealed that the most ignored asset losses in valuation for compensation purposes in Kenya are assets of persons without legally recognizable rights, common property resources and social capital, among others, due to the existing legal provisions. Additionally, valuers often fail to apply the appropriate valuation concepts and methods.

The findings of the study are specific to Kenya since valuations for compensation purposes are statutory in nature and hence the applicable legal frameworks are unique to a specific country, although professionalism issues cut across.

The study may help professional valuers to update their knowledge and apply the right valuation concepts and methods, and also help policymakers to review their policies appropriately to match the best practices.

The findings of the study, if implemented, are likely to enhance acceptability of compensation amounts hence improving the working relationships between the public project implementers and the project affected persons, to the benefit of the both parties.

The study is of value to professional valuers, policymakers and land acquiring agencies to be more vigilant and professional in the process of acquiring interests in land.
