TELECOMMUNICATIONS SERVICE DELIVERY AND STRATEGIC COMMUNICATION: EXPLORING CUSTOMER-CENTRIC HEDGE IN OSUN STATE, NIGERIA
(Kings Journal of Entrepreneurship, Innovation, and Management., 2025-04-02) Omowale Taofeek
In Nigeria’s highly competitive telecommunications sector, brand communication strategies play a vital role in brand differentiation, consumer engagement, and market positioning. However, despite substantial investment in marketing efforts, customer dissatisfaction, service switching, and engagement challenges persist. While scholars have examined competitive strategies and their impact on the performance and consumer satisfaction, there is a dearth of study on service delivery and strategic communication from the consumer perspective. This study thus, examined brand communication strategies use by telecommunication companies in Nigeria with a view to assessing the level of influence that the strategies have on consumer engagement and brand loyalty. Guided by Porter’s generic competitive strategies model, this study adopted a descriptive survey research design. A structured questionnaire was administered to 345 respondents across selected local government areas in Osun State, Nigeria, with responses analysed using SPSS. Findings showed that SMS was the dominant communication strategy used by telecommunication companies to reach their customers, followed by mobile ads and social media. Promotional discounts were the most engaging strategy, while celebrity endorsements and sponsorships were the least effective. Further findings indicated that most respondents found telecommunication advertisements informative. The study concluded that while telecommunication companies in Nigeria employ aggressive marketing strategies, network quality and customer service are stronger drivers of consumer loyalty than promotional efforts. Companies must move beyond over-reliance on SMS marketing and adopt a hybrid communication approach that integrates personalised digital engagement and traditional media to maximise customer satisfaction and retention. It is recommended that telecom firms improve service delivery, refine marketing strategies to reduce message fatigue and adopt more customer-centric communication techniques for long-term competitiveness.

Emergence and spread of two SARS-CoV-2 variants of interest in Nigeria
(Nature communications, 2023-02-13) Femi Ayoade
Identifying the dissemination patterns and impacts of a virus of economic or health importance during a pandemic is crucial, as it informs the public on policies for containment in order to reduce the spread of the virus. In this study, we integrated genomic and travel data to investigate the emergence and spread of the SARS-CoV-2 B.1.1.318 and B.1.525 (Eta) variants of interest in Nigeria and the wider Africa region. By integrating travel data and phylogeo- graphic reconstructions, we find that these two variants that arose during the second wave in Nigeria emerged from within Africa, with the B.1.525 from Nigeria, and then spread to other parts of the world. Data from this study show how regional connectivity of Nigeria drove the spread of these variants of interest to surrounding countries and those connected by air-traffic. Our findings demonstrate the power of genomic analysis when combined with mobility and epidemiological data to identify the drivers of transmission, as bidirectional transmission within and between African nations are grossly underestimated as seen in our import risk index estimates.

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
(Science, 2022-09-15) Femi Ayoade
Investment in SARS-CoV-2 sequencing in Africa over the past year has led to a major increase in the number of sequences generated, now exceeding 100,000 genomes, used to track the pandemic on the continent. Our results show an increase in the number of African countries able to sequence domestically, and highlight that local sequencing enables faster turnaround time and more regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscores the heterogeneous nature of the pandemic and shed light on the distinct dispersal dynamics of Variants of Concern, particularly Alpha, Beta, Delta, and Omicron, on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve, while the continent faces many emerging and re-emerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century.

Resourcefulness of propylprodigiosin isolated from Brevundimonas olei strain RUN-D1
(AMB Express, 2023-07-09) Femi Ayoade
A novel red-pigmented bacterium was isolated from a water sample collected at Osun River, Ede. Morphological
and 16 S rRNA gene sequencing revealed that the bacterium is a strain of Brevundimonas olei, while its red pigment was identified using UV-visible, FTIR and GCMS as a derivative of propylprodigiosin. The maximum absorbance
of 534 nm, the FTIR’s 1344 cm− 1 peak of prodigiosin’s methoxyl C-O interaction, and the molecular ions from GCMS confirmed the pigment’s identity. The pigments production was temperature-sensitive (25 °C), lost at > 28 °C,
and in the presence of urea and humus. In addition, the pigment turned pink in the presence of hydrocarbons,
while its red colour was retained with KCN and Fe2SO4, and enhanced by methylparaben. Furthermore, the pigment is stable in high temperature, salt, and acidic conditions, but changed to yellow in alkaline solution. The pigment, identified as propylprodigiosin (m/z 297), demonstrated broad-spectrum antibacterial activities against clini-
cally important strains of Staphylococcus aureus (ATCC25923), Pseudomonas aeruginosa (ATCC9077), Bacillus cereus (ATCC10876), Salmonella typhi (ATCC13311), and Escherichia coli (DSM10974). The ethanol extract has the highest zones of inhibition of 29 ± 3.0, 26 ± 1.2, 22 ± 3.0, 22 ± 1.5, and 20 ± 2.0 mm, respectively. Furthermore, the acetone pig- ments interacted with cellulose and glucose such that increasing glucose concentrations showed linearity at 425 nm. Finally, the fastness of the pigments to fabrics was excellent, with percentage fadedness of 0 and − 43% light
and washing tests, respectively, in the presence of Fe2SO4 as the mordant. The antibacterial nature of prodigiosin solu- tions and their good textile fastness to fabrics could be essential in manufacturing antiseptic materials such as band- ages, hospital clothing and agricultural applications such as tubers preservation.

Post-Performance Assessment of Nigerian Centre for Disease Control (NCDC) Communication Strategies for Adherence to COVID-19 Safety Protocols among Non-Literates in Southwest Nigeria
(Journal of Mass Communication,, 2024-11-04) Adelabu T. Omowale
This study assesses the post-performance of Nigeria Centre for Disease Control (NCDC) communication strategies in raising awareness and promoting adherence to COVID-19 safety protocols among individuals with low literacy levels in Southwest Nigeria. Quantitative and Qualitative data were collected through surveys (comprising 420 respondents) and 6 focus group discussion sessions (involving 54 participants) respectively in three selected states (Lagos, Osun and Oyo). The results show high level of awareness and knowledge of COVID-19. Also, results show that more than half (51.67 %) of the respondents did not adhere to COVID-19 safety protocol due to distrust in government. Findings further reveal insights into the accessibility, comprehensibility, and cultural appropriateness of communication materials and channels used by NCDC, as well as the effectiveness of community engagement approaches in fostering behavior change among non-literates. Results from the multinomial regression analysis show that age, sex, and information from radio and community health workers significantly predicted the probability of adhering to COVID-19 safety protocols (p<0.05). The study recommends that during pandemic, health communicators should prioritize culturally sensitive communication, train and incorporate influencers that are regarded within the community. Government should foster trust among the population by empathizing with the needs of the population to make public health campaigns effective.
