Purpose - The purpose of this paper is to report on research that examined librarians' perception and acceptance of use of Facebook and Twitter in promoting library services in Oyo state, Nigeria. Design/methodology/approach - The survey design and interview were used to collect data from librarians in Oyo state. The questionnaire contained questions that are pertinent to the issues being investigated. The 81 responses (81 per cent) received were processed, analysed and results presented. Findings - The paper reveals that majority of the libraries in Oyo state, Nigeria, have Facebook profiles, though minority have Twitter accounts. Librarians in Oyo state, Nigeria, have high perception and acceptance of using Facebook and Twitter to promote library services. Findings also reveal that librarians in academic and special libraries in Oyo state, Nigeria, are more highly receptive to use of Facebook and Twitter to promote library services. Findings revealed further that younger librarians showed more positive perception and higher acceptance. Research limitations/implications - While the research was limited to librarians in Oyo state, Nigeria, it has applications to librarians and libraries all over Nigeria. Practical implications - This research provides information on the perceptions and acceptance of social media tools (Facebook and Twitter) in promoting library services. The findings may help provide information to library heads on adopting new and popular technologies to bring the library closer to the user and attract more users and on why it is not being used where they are provided. Originality/value - At the time of completing this study, research had mainly been on librarians' use of social media for personal issues not on librarians' perception and acceptance of using it to promote library services. This research also focuses on libraries in Oyo state having a presence on Facebook and Twitter to promote library service and direct and prompt communication with their users. © 2015 Emerald Group Publishing Limited.

Phyto-beneficial effects of rhizobacteria specifically Enterobacter species were evaluated on maize seedling health and growth. Out of the 19 isolates examined, two were remarkable in their phosphate solubilization efficiency (PSE > 70%), chitinase enzyme activity (CEA > 85%) and antifungal activity with evidence of no or low disease expression in maize seedling. The selected isolates (OSR7 and IGGR11) were identified and 16S rDNA revealed both isolates as Enterobacter species. Re-evaluation of both isolates ascertains that their combined effects are more effective on maize seedling than their individual effects. Their combinations completely suppressed pathogenic activity of Fusarium verticillioides on maize seedling with evidence of no disease symptoms. Other treatments significantly (p < 0.05) expressed varied maize seedling diseases such as leaf curl and stem rot. Apart from treatment T2 (maize + pathogen), other treatments most especially their combinations significantly (p < 0.05) enhanced seedling height, stem girth, leaf area, nitrogen and potassium contents. The phyto-beneficial effects of these Enterobacter species suggest that they could be employed as bio-inoculant for maize seedling health and growth. © 2014, © 2014 Taylor & Francis.

The paper is an extra-linguistic critique of Austin’s speech act theory. In the context of the paper, extra-linguistic issues capture those factors that “legitimize” violations from the norms of English which are evident in Austin’s theory. We investigate the strengths and weaknesses of the theory from a socio-pragmatic perspective, exploring discursively, the Nigerian existential experience. The critique hinges on three evolved theoretical concepts (Geoimplicature, Emergent Context and Pragmadeviant) in the investigation of the strengths and weaknesses of Austin’s speech act theory. The study finds out that despite the strengths of the theory, some postulations therein are bedeviled by the dynamics of human communication. Conclusively, the paper contends for an “illocutionary component” of meaning as opposed to the age-long “propositional component” of meaning. © Australian International Academic Centre, Australia.

This paper has looked at the dynamics of the structures of headlines. Related literature was reviewed on functions and influence of the print media, mass media and language development, and studies in headlines, to give the work the necessary theoretical foundation. The study employed survey approach to look at reportage of headlines of some newspapers in Nigeria. Three questions guided this study: What are the types of headlines cast for the stories? What is the syntactic structure of the headlines? What is the level of social responsibility displayed by the editors, in casting the headlines? A total of 24 headlines were purposively collected as data, and analyzed. The analysis has revealed that ‘plain’, ‘headlines with pointers’, and ‘speech as headlines’ characterized our data. Also, most of the headlines are cast in simple sentence structures. This result is significant for mass media teachers as they apply principles and theories of language, in their business of teaching mass media courses, daily. © Australian International Academic Centre, Australia.

A macromolecule, CML, was obtained by purifying and carboxy-methylating the lignin generated from acid hydrolysis of sugarcane bagasse during bioethanol production from biomass. The CMLs complexed with Al3+ (CML-Al) and Mn2+ (CML-Mn) were utilised for the removal of a textile dye, Procion Blue MX-R (PB), from aqueous solutions. CML-Al and CML-Mn were characterised using Fourier transform infrared spectroscopy (FTIR), scanning differential calorimetry (SDC), scanning electron microscopy (SEM) and pHPZC. The established optimum pH and contact time were 2.0 and 5h, respectively. The kinetic and equilibrium data fit into the general order kinetic model and Liu isotherm model, respectively. The CML-Al and CML-Mn have respective values of maximum adsorption capacities of 73.52 and 55.16mgg-1 at 298K. Four cycles of adsorption/desorption experiments were performed attaining regenerations of up to 98.33% (CML-Al) and 98.08% (CML-Mn) from dye-loaded adsorbents, using 50% acetone+50% of 0.05molL-1 NaOH. The CML-Al removed ca. 93.97% while CML-Mn removed ca. 75.91% of simulated dye house effluents. © 2014 Elsevier B.V.
