Abstract

Copolymer resins of peanut skin tannin extract, aldehydes and cashew nut shell liquid were prepared. The resins were blended with bitumen and used in formulating oleoresinous wood varnishes. The film properties of the varnishes were determined and the results showed that the gloss and scratch hardness of the films increased with increase in the quantity of cashew nut shell liquid/tannin‐aldehyde resins incorporated. The results also showed that the resins improved the chemical resistance of the varnish films. Varnish compositions containing 50:50 of bitumen and the resins gave films with satisfactory physical and chemical properties. The study showed that it is possible to formulate excellent oleoresinous wood varnishes using blends of bitumen and cashew nut shell liquid/tannin‐aldehyde resins.

Abstract

Purpose

The study examined the applicability of TAM2 theoretical constructs of social influence and cognitive instrumental factors vis-à-vis the facilitation of perceived usefulness of electronic resources among library personnel in private universities in South-west Nigeria.

Design/Methodology/Approach

Descriptive research design of correlational type alongside the single-stage random sampling technique were used to select 212 respondents from a population size of 259 library personnel across the 21 private universities in South-west Nigeria. The instrument used to elicit data was the questionnaire. Of the 212 copies of the questionnaire administered, 181 (85.4 per cent) were found valid for analysis.

Findings

Social influence and cognitive instrumental factors significantly had relationship with and facilitated perceived usefulness of electronic resources. Similarly, the study revealed that cognitive instrumental factors are stronger facilitators of perceived usefulness of electronic resources than social influence factors among library personnel in private universities in South-west, Nigeria.

Practical implications

Implementation of electronic resources without ascertaining library personnel usefulness perception leads to resource underutilisation and wastage. Management of private university libraries should, therefore, take into cognisance the usefulness perception of library personnel before the implementation of electronic resources for optimum utilisation.

Originality/value

There is no known research endeavour within the Nigerian context that examined perceived usefulness of electronic resources among library personnel in the private university domain, using the additional theoretical constructs of TAM2 as our research model suggests. This study is, therefore, a pioneering effort towards ascertaining library personnel’s perceived usefulness of electronic resources prior acceptance and use in private university libraries.
