    Get PDF
    With the rapid advancements in technology and the democratization of media topology in Nigeria, many people are increasingly gaining access to the media and becoming empowered to actively participate in public debate about issues affecting them in addition to having a great deal of online social interactions. However, people’s access to and interactions with technology and other media have given rise to a host of malicious effects – propagation of doubtful and fabricated content. This has been shown to have the potential to adversely influence people’s lives and sense of judgment, especially regarding democratic processes such as political campaigns during which many malicious fabricated contents are disseminated. In recent history, from 2016, election campaigns in various countries across the world have highlighted how fake news can be targeted at specific people or individuals to influence and misguide them, and even influence polls results. Ever since, issues surrounding fake news and its impacts on democratic and social settings have been gaining pervasive research attention. Hence, the urge to explore the concepts of misinformation and democracy from a Nigerian context through a review of extant literature. In conclusion, several propositions were made, and a conceptual framework was designed for future research to explore the concept and empirically proffer solutions to the growing menace.

    Police-Public Media Relations: Issues and Challenges

    Get PDF
    Police-Public relations is the subject of Police-Media Relations. The Police and the media are two institutions that are aimed at ensuring that the society lives well based on lawful and orderly conduct in the interest of justice, fairness and development of the society. The two institutions require information from the public to perform their duties prudently and diligently. However,  they differ in orientation, operational techniques, platforms and public perception. A typical scenario for instance, if there is an uprising, attack, disaster or any such unfortunate occurence, members of the public will be running to safer areas.  It is common see the Police and the media are pushing their way forward into that ‘danger zone’ to perform their individual responsibilities. Both the Police and the media depend on sources for information to facilitate their work, though they differ significantly in approaching the subject matter; thus the Police interrogate to get information, the journalist on the otherhand, interviews to secure information. It is undeniable fact that, the two institutions require each other in the performance of their responsibilities and therefore need to develop a harmonious and cordial relations. One fact is that the Police have bags of information that the media require, likewise, the Police require the visibility and bridge that the media provide to link them with the society in a positive manner in order to have a goodwill from the public. Daily, the media reports on issues partaining crime or about the Police, the crime news and other sensational events excite the public and it enables them to appreciate the effort of the government or that of the Police on crime prevention and control. These inevitably indicates that the media and the police must work together. However, over the years there exists a mixed relation between them, this paper identifies those challenges affecting the duo relations and recommends ways to overcome those challenges.

    In this paper,relationship between rainfall and groundwater recharge estimation was evaluated. A standard numerical formula that relates rainfall to groundwater recharge estimation was proposed with the aim of providing error-free groundwater estimate from rainfall. Rainfalls measured in a selected location in Yola, Nigeria and standard formula were used to fix the constants (A,B and c) in the new numerical formula using Microsoft Excel Solver. The constants were used to establish new numerical formula. The new numerical formula was used to estimate groundwater recharge from the rainfall. The accuracy of the new numerical formula was evaluated statistically using Analysis of Variance (ANOVA), relative error; the degree of accuracy, numerical reliability, Model of Selection Criterion (MSC) and Akaike Information Criterion (AIC) and compared with the previous formulae in use for field groundwater recharge estimation with Uttar Pradesh (UP) as the reference value of groundwater recharge. The study revealed that groundwater recharge estimated using the formula was similar to groundwater recharge estimated using standard formulae (UP, Modified Chaturvedi, Kumar and Seethapathi and Rao). In all cases there were significant differences between the groundwater recharge estimated using all the formulae. The new formula provided the lowest relative error of 0.887%, the highest MSC of 4.911; the degree of accuracy of 99.113 % and the lowest AIC of 436.306.  The accuracy of the formulae was in the order of new formula greater than Chaturvedi formula greater than Kumar and Seethapathi formula greater than Rao formula. It was concluded that modelling of groundwater recharge using the numerical formula is a promising tool for estimating groundwater recharge with minimum error in water resources management

    The objective of this study was to evaluate if the plant extract could provide antifungal potential against some pathogenic fungi. Extract of Dichloromethane solvents was used for disc diffusion assay. The inhibitory concentration of the extract was performed by broth dilution method and zone of inhibition was studied by disc diffusion method at the concentration of 25, 50, 100, 250, 500 and 1000ppm in DMSO. Fluconazole was used as the reference control for antifungal study. The extract showed maximum inhibition potential of zone of inhibition against most of the pathogen (Aspergillus niger, Aspergillus flavus, Candida tropicalis and Fusarium oxysporium) used at concentration 25ppm to 250ppm with zone of inhibition (3.45±0, 3.33±0.12, 3.07±0.05 and 2.97±0.10mm respectively). The extract showed minimum inhibition potential against Fusarium oxysporium in all the concentration when compared with the control as well as to the other pathogens. Aspergillus niger and Aspergillus flavus was found to be more sensitive to Dichloromethane leaf extract followed by Candida tropical and lastly fusarium oxyspurium. The Present study indicates the potential usefulness of Dichloromethane leaf extract of Leptadenia hastata as antifungal agent. © 2018 Isaac John Umaru, Fasihuddin A. Badruddin, Henry Y.
