Abstract

Purpose

The purpose of this paper is to ascertain the management of institutional repository (IR) in Nigerian universities.

Design/methodology/approach

The study took the form of a descriptive survey, gathering data from academics and repository mangers from 15 universities that have their IR captured on OpenDOAR.

Findings

The results showed that most academics submit their work for archiving in IR, and the types of materials submitted are mostly journal articles and conference proceedings. Contents are archived, using self-archiving and mediated submission. Some universities do not provide support and motivation towards the research works of their staff.

Practical implications

The implication of the study lies in the adoption and implementation of the framework presented in this work to ensure the growth and sustainability of IR.

Originality/value

The study is based on the findings presented a framework to guide repository managers to ensure effective management of IR.

Abstract

Purpose

This study aims to show that digital literacy can serve as a tool for effecting social change and highlights the achievements of an academic library in digital content creation using the Wikipedia platform.

Design/methodology/approach

The study adopted qualitative research method, Interview and document analysis were used for data gathering. Data gathered were analysed using content (conceptual) analysis.

Findings

Findings showed that the library has created or edited digital content for various categories of women, such as women in academia, industry and politics. These entries have received more than eight million views over a period of two years, which shows that the entries are being utilised. However, the editing exercise had been confronted with challenges such as accessing reliable citations in terms of the notability and verifiability policy of Wikipedia amongst others.

Practical implications

Currently, people rely more on online resources for their research, leaving physical library resources unused. Even, more students start their research online using Wikipedia. Thus, libraries could create visibility for their physical material using regularly visited sites like Wikipedia and its sister projects such as Wikidata; otherwise, these physical materials will remain invisible to the people that needed them.

Originality/value

Contributing to Wikipedia by creating a new entry or editing an existing one can help students to deepen their knowledge about a subject; Wikipedia editing may serve as an avenue for improving information literacy skills. Drawing from the theory of cyberfeminism as used in the study, information and communications technology has the potential to empower women and transform gender relations.

Abstract

Purpose

The purpose of this study is to examine the acute toxicity and antidiabetic activity of Asystacia gangetica leaf ethanol extract.

Design/methodology/approach

The study was designed as completely randomized in vivo experimental model. Where acute toxicity study was carried out using 30 albino mice, randomly assigned into six groups of five mice each. Toxicity signs and mortality were observed in the rats within a period of 24 h. The acute and sub-acute antidiabetic study was carried out using 50 rats, randomly assigned into five groups of 10 rats each. The rats’ blood glucose levels were determined and used to assess the acute and sub-acute antidiabetic activity of the extract.

Findings

Results obtained from the acute toxicity study indicated no death in any of the study groups, even at 5,000 mg/kg body weight and showed no signs of toxicity. The acute antidiabetic study showed that treatment with 400 mg/kg of the extract significantly (p = 0.01) lowered glucose level in the diabetic rats from 430.6 to 177.4 mg/dl while 800 mg/kg brought down glucose level from 370 to 144.2 mg/dl by the end of 6 h following administration when compared with the diabetic control group. It was observed that the effect of the extract mostly at 800 mg/kg also compared favorably with that of the standard drug (glibenclamide), which lowered glucose level in diabetic rats from 374.2 to 176.4 mg/dl. Furthermore, the significant reduction was evident from 4, 2 and 2 h for 400 mg/kg extract, 800 mg/kg extract and 5 mg/kg glibenclamide, respectively. At sub-acute level the blood glucose was lowered from 155.6 to 127.2 mg/dl, 137 to 124.4 mg/dl and 151.8 to 121.8 mg/dl for diabetic rats treated with 400 mg/kg, 800 mg/kg and 5 mg/kg glibenclamide, respectively, when compared to the diabetic untreated rats, which ranged from 417.6 to 358.6 mg/dl. The biochemical profile, lipid profile and hematological examination were all positively restored near to normal with the herbal treatment at the different doses. At histopathology level, the liver of the rats treated with 400 mg/kg had moderate portal inflammation without interface or lobular hepatitis while that of 800 mg/kg showed severe portal inflammation with the interface and lobular hepatitis with extensive confluents necrosis. The pancreatic cells of the treated rat showed no significant difference in the β-cells of the islets of Langerhans with hyperplasia of the acinar cell when compared to the diabetic untreated.

Research limitations/implications

The record of no death and signs of toxicity implies that the extract is safe for consumption even at a high dosage of 5,000 mg/kg body weight. The significant (p = 0.01) reduction in the plasma glucose level of the treated rats as compared to the control is an indication of blood glucose-lowering potential of the extract at two different doses. The significant reduction evident of the extract at different hours and days for the two doses implies that the extract rate of lowering potentials is dose-dependent. The evidence of moderate-severe portal inflammation with the interface and lobular hepatitis at 800 mg/kg treatment is an indication that the intake of this herb at high dosage for long period is not safe for the liver tissue.

Practical implications

The outcome of this study suggested that the Asystacia gangetica should also be used as a vegetable in-home food preparation and food processing to use its antidiabetic effect. The herbal extract could also be incorporated into a food product and processed into herbal tea bag for convenient. The subjection of this herbal plant to heat treatment during processing could be a possible avenue to make it safe.

Social implications

The economic burden and complications of diabetes mellitus management will be reduced if the practical implication of this research finding is implemented in foods as vegetable and in functional food production.

Originality/value

This study revealed that Asystacia gangetica leaf extract may be safe and effective for use at a low dose for acute management of diabetes mellitus. This research may be of value to those living with diabetes mellitus.

Abstract

Purpose

University intellectual output such as theses and dissertations are valuable resources containing rigorous research results. Library staff who are key players in promoting intellectual output through institutional repositories require skills to promote content visibility, create wider outreach and facilitate easy access and use of these resources. This study aims to determine the skills of library staff to enhance the visibility of intellectual output in federal university libraries in southeast Nigeria.

Design/methodology/approach

A survey research design was adopted for the study. The questionnaire was used to obtain responses from library staff on the extent of computer skills and their abilities for digital conversion, metadata creation and preservation of digital content.

Findings

Library staff at the university libraries had high skills in basic computer operations. They had moderate skills in digital conversion, preservation and storage. However, they had low skills in metadata creation.

Practical implications

The study has implications for addressing the digital skills and professional expertise of library staff, especially as it concerns metadata creation, digital conversion, preservation and storage. It also has implications for the university management to prioritize the training of their library staff in other to increase the visibility of indigenous resources and university Web ranking.

Originality/value

This study serves as a lens to identify library staff skill gaps in many critical areas that require expertise and stimulate conscious effort toward developing adequate skills for effective digital information provision. It sheds light on the challenges that many Nigerian university libraries face in their pursuit of global visibility and university Web ranking.
