INTEGRATING DIGITAL TOOLS AND EDUCATIONAL STRATEGIES FOR ENHANCING SUSTAINABLE WORKPLACE COLLABORATION: A POSITION PAPER
No full textThe rapid digitalisation of workplaces has brought about significant changes in how organisations operate and collaborate. Digital tools, such as communication platforms, project management software, and collaborative applications, have transformed team dynamics and organisational structures. However, the successful and sustainable integration of these tools is not solely dependent on their implementation but also on the educational strategies that support their use. This paper argues that digital tools, when integrated with educational strategies such as continuous professional development, leadership training, and the promotion of a lifelong learning culture, can enhance workplace collaboration and productivity sustainably. It contends that the mere adoption of digital tools without the corresponding educational support can result in digital fatigue, communication breakdowns, and fragmented teamwork. By examining existing literature and drawing on examples from different sectors, the paper highlights the importance of aligning technology adoption with well-structured educational frameworks to ensure that employees are equipped to utilise digital tools effectively. Furthermore, it explores how leadership, customised training programmes, and an organisational culture that values collaboration can foster a resilient workforce capable of adapting to the rapidly changing digital landscape. This paper concludes with recommendations for organisations aiming to enhance their collaborative potential through a synergistic approach that combines digital and educational strategies, ensuring that the benefits of digital transformation are maximised and sustained in the long term. These insights provide a roadmap for organisations seeking to build sustainable, collaborative environments in an increasingly digital world

THE DEATH OF PROVERBS? FATE OF TRADITIONAL WISDOM IN THE FACE OF MODERN LANGUAGE TRENDS
No full textProverbs, often described as the mirror of culture and the vessels of ancestral wisdom, have played an essential role in shaping moral, ethical, and philosophical thought across generations in African societies. However, in the 21st century, the global dominance of modern language trends—such as slang, internet abbreviations, emojis, memes, and the use of artificial intelligence-driven communication—has marginalized traditional expressions like proverbs. This study investigates the fate of proverbs in contemporary Nigerian society, particularly focusing on how modern language trends contribute to their decline. It anchors on the concepts of cultural lag, language shift and ethnolinguistic vitality theory. Using a qualitative research approach, interviews and focus group discussions were conducted with elders, teachers, and students across three southeastern Nigerian communities. The findings reveal that digital communication, western education, urbanization, and linguistic globalization have led to a steady decline in the usage and comprehension of proverbs among youths. The study recommends that educational institutions, media organizations, and cultural bodies take deliberate steps to integrate proverbs into modern communication platforms, ensuring the survival of traditional wisdom amid linguistic evolution
TESTING THE USE OF AEROMAGNETIC DATA FOR THE DETERMINATION OF DEPTH TO MAGNETIC BODIES IN NKALAGU AND ENVIRONS
No full textHigh resolution aeromagnetic data of Nkalagu and its environs in South-Eastern Nigeria has been acquired and analyzed using slope method, in order to determine the depth to magnetic bodies, as well as delineate the basement morphology and the structural features within the study area. The qualitative assessment of total magnetic intensity (TMI) and residual anomaly maps of the study area reveal that the study area possesses high magnetic intensities which ranges from 7890 nT to 8114 nT and -110 nT to 104 nT respectively. The analytical map reveals that the structural trend within the study area is mainly Northeast-Southwest and (NE-SW) directions which agree with the fault orientation within the Benue Trough, also The area is intensely fractured with major regional faults trending in Northeast-Southwest (NE-SW) direction. Five (5) selected magnetic profiles were taken perpendicular to the direction of the magnetic anomalies, namely K-Kᴵ, L-Lᴵ, M-Mᴵ, N-Nᴵ, and O-Oᴵ. The slope method analysis revealed that the study area possess a two layer depth model; the shallower and deeper bodies which varied from 1.68 km to 2.05 km and 2.84 km to 6.38 Km respectively. The basement tomography map suggest thick sediment with their contours widely spaced at the northern and Eastern parts, and shallow sediment toward the Western part with contours closely spaced. The 3-D tomography map shows the presence of peaks (uplifts) and depressions, a typical expression of folds. The findings suggest that the study area is highly fractured and possesses possible mineralization path and the existence of high Cretaceous sedimentary thickness may favour hydrocarbon accumulation
STRUCTURAL ATTRIBUTES AND SEQUENCE OF ENTRY OF INDEX MINERALS IN THE ROCKS AROUND SHINTAKU AREA OF SOUTHEASTERN PART OF LOKOJA, NORTH-CENTRAL, NIGERIA
No full textThis study delineates the structures (faults, folds, foliation trends, and joints) and index minerals on the schists, gneisses, migmatites and granites that are pervasive in the Shintaku area of the southeastern part of Lokoja, North-Central, Nigeria. Field descriptions of the rocks associated with the Basement Complex in the area under study revealed that the metamorphic rocks were deformed (foliated) in the NNE/SSW direction from the plot on the Rose diagrams. The trend on the same set of diagrams made from the joint sets showed that the major stress that impacted on the rocks occurred in the N/S direction while the minimum stress is in the E/W direction. The relationship between this structural trend and the Pan African orogeny is rather striking. The stresses caused by the Pan African orogenic events must have exceeded a critical value after the rocks had already undergone elastic behaviour making them susceptible to the deformations. The order of entry of the diagnostic minerals into the pelitic rocks also showed that metamorphism in the area ranges from greenschist to amphibolite facies. The prograde regional metamorphism is likely associated with the anatexis that formed the migmatites
AN EFFICIENT ENERGY-MANAGEMENT SYSTEM WITH IOT SENSORS FOR AUTONOMOUS APPLICATIONS
No full textThe Internet of Things (IoT) is a rapidly growing technology that has the potential to revolutionize many industries. However, the energy consumption of IoT devices at the physical layer is a major challenge that needs to be addressed. This paper proposes a novel energy-efficient consumption model with cloud-based controllers for perception layer data acquisition and storage in IoT applications. In the methodology, mathematical representation of the non-optimized energy consumption of physical layer components was first developed before developing the optimized version. The mathematical models were then implemented in software using embedded C language, a hybrid of assembly, C and C++ languages. The developed software was implemented using ATMEGA 2560 as a target microcontroller with IoT sensors interfaced to it. The system was simulated using proteus professional software. Results show that the optimized algorithm developed brought 54.75% in improvement in energy consumption of physical layer components in IoT autonomous applications. Further study shall focus on the application of the models developed in this work in cloud-based applications where security is a concer

EXTENDED PSEUDO-LINDLEY POISSON DISTRIBUTION: A NEW MODEL FOR COUNT DATA WITH APPLICATION TO VIRULENT TUBERCLE BACILLI DATA
No full textThis paper introduces a new lifetime probability distribution called the Extended Pseudo-Lindley-Poisson Distribution (EPLPD), which generalizes the Pseudo-Lindley Distribution and the Poisson Distribution. The EPLPD is designed to model count data with varying degrees of dispersion, including zero-inflation and over dispersion. We derive the properties of the EPLPD, including its probability mass function, cumulative distribution function, moments, and moment generating function The maximum likelihood estimation method is used to estimate the parameters of the EPLPD. To demonstrate the applicability of the EPLPD, a numerical example was the survival times (in days) of 72 Guinea pigs infected with virulent tubercle bacilli is presented, demonstrating the distribution\u27s superiority over existing models. The results show that the EPLPD provides a better fit to the data compared to the Poisson and Lindley distributions. The EPLPD can be used to model various types of count data in fields such as medicine, biology, and engineering. The EPLPD offers a valuable tool for analyzing count data in various fields, including medicine, biology, and public healt
Impact of Magnetic Field on Waves in A Rotating Inhomogeneous Material Under Imperfect Boundary and Inclined Mechanical Load: Inhomogeneous Impedance Consideration
No full textWe present in this investigation a Mathematical wave analysis and model for surface waves in an imperfect boundary of a rotating inhomogeneous medium under a mechanical inclination. The imperfect boundary of the material is assumed to be in the form of impedance-corrugated surface. Mathematically, we assumed this corrugation in the form of trigonometric Fourier series. While the inhomogeneous nature (both of the material and impedance parameters) is taken to be an exponentially decaying function of the material parameters. In modelling this, the dynamical equations for the rotating impedance-corrugated boundary of an inhomogeneous fibre-reinforced solid influenced by magnetic fields and inclined mechanical load were analytically derived and presented using the fundamental constitutive laws of stress-strain relations in solid Mechanics of materials. We employ the Eigenvalue method also called the normal mode analysis approach in deriving the analytical solution of the fields’ distributions of the system; displacement components, and normal and shear stresses. Computational solutions in graphical forms were presented using MATHEMATICA 11 software, for the derived fields’ distributions of displacement components, normal and shear stresses on the material as occasioned by the wave propagation. We observed that the impact of the inhomogeneous parameter, rotation, magnetic field, angle of inclinations, impedance-corrugated surface parameters on the fields’ profiles on the material is remarkable. This is such that an increase in rotation, and angle of inclination of the medium produces an increase behavior of the fields’ profiles. The magnetic field influenced the normal stress in a decreasing manner when increased whilst noting mixed behavior of the displacements and shear stress. The angles of inclinations caused upward trends to the behavior of the displacements and stresses of the wave on the medium. A resistant-like effects were observed along the normal stress components when the inhomogeneous normal impedance is increased
Casson Fluid Flow in a Vertical Channel Incorporating Suction, Heat Sink and Dufour Mechanisms
No full textIn this paper, we have investigated Casson fluid Flow in a vertical channel incorporating suction, heat sink and Dufour mechanisms. The governing equations are modeled using Casson model by considering Dufour and heat sink. The equations are non-dimensionalised by defining suitable dimensionalising parameters. The resulting equations are nonlinear and coupled. These are tackled by employing regular perturbation technique. Velocity, temperature and concentration are plotted for various physical parameters which affects the flow and are analysed graphically. The method is observed to give good agreement. It is seen that increase in Dufour and heat sink parameters lead to rise in both thermal and momentum boundary layers
