Extent of Involvement of Planning and Coordination Practices For Conflict Management in College Of Education Libraries in South-East and South-South Nigeria

The study investigated the extent of involvement of planning and coordination practices for conflict management in college of education libraries in south-east and south-south Nigeria. Descriptive survey design was employed in the study while two research questions were answered. The population and sample of 528 members of colleges of education library staff in South East and South-South, Nigeria was used for the study using a non-randomized purposive sampling method. A structured questionnaire titled Planning and Coordination Practices for Conflict Management in Libraries Questionnaire (PCPCMLQ) was used for the study. The instrument was face and content validated through consultation with three Veteran Researchers in Library and Information Science, Educational Psychology and Measurement and Evaluation from University of Nigeria Nsukka and Nnamdi Azikiwe University Awka. Pearson’s Product Moment Correlation was used to obtain a reliability co-efficient, r = 0.88, which confirmed the instrument is consistent in its measurement. Mean, , and Standard deviation, SD. The results revealed among others that, to a high extent, coordination is carried out as a conflict management practice to enhance service delivery in college of education libraries. It was concluded that effectively harnessing the potentials of planning and coordination practices for conflict management will no doubt lead to enhanced service delivery in college libraries. The study recommended for adequate planning and coordination practices for conflict management that will enhance service delivery in college of education libraries in South-East and South-South, Nigeria

Extent of Practices of Staffing and Funding for Conflict Management in College of Education Libraries in South-East and South-South, Nigeria

The study examined the extent of practices of staffing and funding for conflict management in college of education libraries in south-east and south-south, Nigeria. The study was carried out using a descriptive research survey method, and two research questions were drafted to guide the study. A sample size of 528 members of colleges of education library staff in South East and South-South, Nigeria was drawn and used for the study a purposive sampling technique. A structured questionnaire was used to collect relevant data for the study. The questionnaire was validated through consultation by 3 research experts. Pearson’s Product Moment Correlation was used to ascertain reliability of the questionnaire, and this gave, r = 0.88, which certifies that the questionnaire was appropriate for data collection for the study. Data collected was analysed using Mean, , and Standard deviation, SD, and the result partly showed that staffing and funding practices are carried out for conflict management for enhanced service delivery in college of education libraries. The study concluded that if practices of staffing and funding were maximally channeled to managing conflicts in college libraries, service delivery of the college staff would be enhanced. It was recommended that there should be appropriate allocation and utilization of fund meant for library programs, policies and projects to avoid lapses in implementations of well through conflict management policies for the libraries

Anti-plasmodial and anti-inflammatory activities of cyclotide-rich extract and fraction of Oldenlandia affinis (R. & S.) D.C. (Rubiaceae)

Background: Oldenlandia affinis, commonly called ‘kalata-kalata’, a versatile plant used locally to treat malaria fever in some parts of sub-Saharan Africa was investigated for anti-plasmodial and anti-inflammatory activities.Objective: The study was designed to evaluate the antiplasmodial as well as anti-inflammatory activities of whole extract and cyclotide-rich fraction of Oldenlandia affinis.Method: The dichloromethane-methanol extract (ODE) of the plant, O. affinis was investigated for suppressive and curative antiplasmodial activities against Plasmodium berghei in mice. ODE and the cyclotide-rich fraction (CRF) was investigated for chronic and acute anti-inflammatory activities in rat models of inflammation. Inhibition of pro-inflammatory mediators was studied in RAW264.7 macrophages.Results: ODE exhibited significant (p<0.05) reduction in mean parasitaemia in both the suppressive and curative models of Plasmodium berghei infection in mice.Administration of ODE(100, 200, or 400 mg/kg) and CRF (100, 200, or 400 mg/kg) produced significant inhibition of rodent models of acute and chronic inflammation . This observation is supported by the significant (P<0.05) inhibition of pro-inflammatory mediators, inducible nitric oxide (iNO) and tumour necrosis factor-alpha (TNF-α), and the reactive radical scavenging activities in RAW264.7 macrophages.Conclusion: These findings could explain, at least in part, the successes reported in the use of the herb, Oldenlandia affinis in the traditional treatment of malaria feverKeywords: Oldenlandia affinis, Reactive oxygen/nitrogen species, Plasmodium berghei, pro-inflammatory mediators, parasitemi

Histological staining properties of Khaya senegalensis wood dust extracts: a preliminary study

Crude aqueous and methanol extracts of Khaya senegalensis wood dust were employed as histological stains for the demonstration of general tissue architecture. Preliminary phytochemical screening of the extracts was conducted. Mixtures of the extracts of K. senegalensis in acidic, alkaline and neutral solutions were used to stain tissue sections. Preliminary phytochemical screening revealed that K. senegalensis extracts contains flavonoids, saponins, tannins, glycosides and reducing sugars. Optimum staining time was 15 minutes for both extracts and they stained the tissues in different shades of red and brown in the various media used. The best and worst stain uptake of tissues was observed with both extracts in alkaline and neutral media respectively. Mordant preparation of the extracts produced no significant staining difference from the non-mordant preparations. Staining solutions of the extracts have better affinity for the cellular cytoplasm and hence gave a good contrast when compared with Hematoxylin and Eosin control sections. In conclusion, Khaya senegalensis wood extract is a promising histological stain for the demonstration of general tissue architecture.Keywords: Khaya senegalensis, wood dust, stain, histology, mordan

Occurrence and risk assessment of phenolic endocrine disrupting chemicals in shallow groundwater resource from selected Nigerian rural settlements

To date, limited information exists on the distribution of endocrine disrupting compounds in groundwater resources from African rural settlements. In view of this knowledge gap, the present study investigated the concentrations and potential health risks of phenolic endocrine disrupting chemicals (EDCs) in underground water samples obtained from eight rural settlements in Nigeria, West Africa. The water samples were obtained from domestic drinkable communal wells at Anambra (Mgbaukwu and Umudioka), Lagos (Bariga, Itire and Mushin), and Delta (Agbarho, Ikweghwu and Orhokpokpor) states representing the South-East, South-West and South-South Nigeria respectively. Samples were analyzed for 10 selected chlorinated, nitrogen-containing and alkyl phenolic compounds using gas chromatography coupled with flame ionization detector technique. At all understudied sites, selected phenolic compounds with the exception of 2-chlorophenol which was below detectable limits at 4 sites (Agbarho, Mgbaukwu, Umudioka site 1 and Mushin) were detected. The concentrations of the phenolic compounds in the samples from the different sites ranged between below detectable limits to 0.0904 ppm. Nonylphenol, 2,4-dinitrophenol and 2,4,6-trichlorophenol were predominant at EDCs in most sites when compared with the other phenolic contaminants. The calculated chronic daily intake (CDI) results for the exposed populations at the communities implies that the level of occurrence and daily intake of 2-nitrophenol, 2,4-dimethylphenol, 4-nitrophenol, 2-chlorophenol and bisphenol A were still below their respective oral reference doses. Nonylphenol and 2,4,6-trichlorophenol (risk quotient, RQ > 1) were identified as the major EDC contributors to potential health risk for exposed populations at the communities
