“Shorsh,” “Sors,” or “Church” - Who cares? Accents and Linguistic Capital in Nigeria
(Ajayi Crowther University, 2026-04-09) Sogunro, Bolanle Olufumbi
The word “accent” in this title and lecture simply means,“The cumulative auditory effect of those features of pronunciation which identify where a person is from, regionally or socially” (Crystal, 2008:3).Once upon a time, probably, like many people here, I would have offhandedly erroneously answered that is pronunciations like “shorsh” and “sors” were due to poor oral English skills or the influence of Nigeria's indigenous languages. Over my years of research, however, I have found out that the matter is much deeper. Trying to empirically find the reason(s) behind mispronunciations is what has kept me in my chosen special area of interest, that is, Sociophonetics, and informed the topic of today's inaugural lecture. Sociophonetics is a combination of the concerns of sociolinguistics and phonetics. Sociolinguistics is defined by Crystal (op.cit.) as “A branch of linguistics which studies all aspects of the relationship between language and society” (440), while phonetics is “The science which studies the characteristics of human sound making, especially those sounds used in speech, and provides methods for their description, classification and transcription” (363). Both sociolinguistics and phonetics are under the broad umbrella of Linguistics, which itself simply means “the scientific study of language” (Crystal, 283).
Applications of Microbial Proteases: A Review
(Journal of Multidisciplinary Sciences: MIKAILALSYS, 2026-03-08) Fasiku, Samuel Adedayo; Afolabi, Femi Johnson; Odeyale, Christiana Ify
Microbial proteases have attracted increasing attention as eco-friendly biocatalysts because of their broad functional versatility and advantages over proteases derived from plants and animals. This review examines the major sources, classification, production methods, and sectoral applications of microbial proteases. Produced by bacteria, actinomycetes, and fungi, microbial proteases are classified according to optimum pH range, catalytic mechanism, and site of action, and are commonly generated through submerged and solid-state fermentation. The review shows that these enzymes have diverse industrial applications in detergent, leather and tanning, food and dairy, brewing and beverage processing, and textile production. In medical and pharmaceutical contexts, microbial proteases are applied in wound debridement and healing, antimicrobial and antibiofilm activities, drug development, diagnostics, and therapeutic interventions. In agriculture, they support animal feed supplementation by improving protein digestion and function as biological control agents by disrupting pathogen attachment, penetration, and colonization of plant tissues. In the environmental sector, their applications include waste management, bioremediation, and the recycling of keratinous and other protein-rich wastes. Overall, this review underscores the wide-ranging utility of microbial proteases across industrial, medical, agricultural, and environmental sectors, highlighting their potential as sustainable biological agents for diverse biotechnological applications.
Reformation in the Redeemed Christian Church of God (RCCG): Examining Adeboye’s Reforms and the Growth of RCCG
(DEPARTMENT OF RELIGIONS, FACULTY OF ARTS, UNIVERSITY OF BENIN, BENIN CITY, EDO STATE, NIGERIA, 2025-06-30) Okunoye, Job Oluremi; Olujobi, Adeleke Adeyemo
The Redeemed Christian Church of God (RCCG) is a Pentecostal denomination with its international headquarters at Redemption City, Mowe, Ogun State, Nigeria. It has its presence in many countries and it is one of the fastest-growing denominations in the world. After the death of founder Pa Josiah Akindayomi in 1980, Pastor E.A. Adeboye became its General Overseer in 1981. Adeboye Erra has witnessed many reforms that have led to the massive growth of the church. This paper examined the similarities between Luther's Reformation and that of Adeboye in RCCG. It makes use of the historical method and interviews with some
long-standing members of the church. Findings show that Adeboye brought in some reforms that led to the growth of the church. For instance, he changed the liturgy of the church from its original African indigenous model to a Pentecostal genre. He created model parishes and allowed the ordination of women. Adeboye's belief resonates with Luther's belief in the priesthood of all believers as against the Catholic stand on the theory of two estates. The work postulates that reformation should not be seen as an invent of the 16th century but an on-going process in many churches. The paper recommends that Christian denominations should not be dogmatic but receptive to changes that will make people amenable to the without compromising bible standards.
Caring for the Poor, the Marginalized, and the Oppressed (Matthew 25:31-46): A Case Study Of Oke-Ogun Baptist Conference, Oyo State, Nigeria
(DEPARTMENT OF RELIGIONS, FACULTY OF ARTS, UNIVERSITY OF BENIN, BENIN CITY, EDO STATE, NIGERIA, 2025-06-30) Okunoye, Job Oluremi; Olayiwola, Mayowa Taiwo
In a country like Nigeria where poverty, marginalization, and oppression persist as pressing social issues, faith-based organizations play a crucial role in addressing these challenges. Therefore, this paper examines the theological and practical dimensions of the Oke-Ogun Baptist Conference’s commitment to social justice and care for the needy, grounded in the biblical foundation of Matthew 25:31-46. The Christian responsibility to support marginalized populations is the dominant motif of the selected passage. The historical development of the Oke-Ogun Baptist Conference is then examined, highlighting its mission, vision, and previous efforts in social welfare. The paper details current outreach initiatives, including support for the poor, marginalized communities, and advocacy for the oppressed. Through case studies, it presents success stories, identifies ongoing challenges, and extracts valuable lessons for effective ministry. The role of community engagement, partnerships, and sustainable support systems is emphasized, underscoring the Church’s pivotal role in driving social change. The article concludes with practical recommendations for enhancing the impact and sustainability of the Conference’s social justice efforts.
Characterization of silver nanoparticles synthesized from Helianthus annuus leaf extracts and antibacterial potential against foodborne pathogens
(Discover Chemistry, 2026-03-11) Fashogbon, Racheal Oluwayemisi; Adejoh, Olubunmi P.; Fasiku, Samuel Adedayo; James, Stephanie N.; Ajayi, Olutosin O; Adeyemi, Abiodun A.
The synthesis of nanoparticles using biological substances, such as plants, has proven to be more beneficial, eco-friendly, and cost-effective. This study emphasised the green biogenic synthesis of silver nanoparticles (AgNPs) from Helianthus annuus L. leaf extracts in ethyl acetate (AgNPEa) and methanol (AgNPM), along with antibacterial and antioxidant properties of the resulting nanoparticles. The phytochemical analysis of the ethanol and ethyl acetate extracts was done. Characterization (UV-visible (UV-Vis), Fourier transform infrared (FT-IR), energy dispersive X-ray (EDX), scanning electron microscopy (SEM), X-ray diffraction techniques (XRD) and FTIR), antioxidant and antibacterial potential of the synthesised AgNPs were done. The two extracts showed no cardiac glycosides. A change in colour of the silver salt solution, showing a maximum UV-vis absorbance at 450 nm for AgNPMHa and 500 nm for AgNPEaHa. The SEM and TEM revealed a spherical shape having about 26.8 ± 9.4 nm and 22.3 ± 6.8 nm size. The EDX showed a high silver content of 69.35% in AgNPMHa and 72.40% in AgNPEaHa while XRD showed planes of pure silver ions. FTIR analysis the capping and stabilization of nanoparticle. Hydrogen peroxide, reducing power and total antioxidant activity increased dose-dependently (55 ± 23%, 63%, and 57% for AgNPEaHa and 57.03 ± 17%, 69.62 ± 21%, and 56% for AgNPMHa at 400ul) and both susceptible to Escherichia coli. The results confirmed that Helianthus annuus is a potential biomaterial for synthesizing AgNPs which can be exploited for its antioxidant and antibacterial activity
