PRELIMINARY SCREENING ON NIGERIAN CHICKEN-TYPES FOR EXTINCTION PROBABILITY
(Animal Science Association of Nigeria (ASAN)., 2025) Abdulyekeen Olanrewaju Abdulraheem, Bashar Ali Adamu, Abba Mohammed, Jummai Adamu, Jimoh Olalekan Aremu, Abdulrazaq Onimisi Raji, and Jibrin Aliyu
This study was conducted in Borno state to assess the extinction risk of sixty (60) 6-Nigerian indigenous chicken-types; normal feathered, frizzle feathered, naked neck, shank feathered, crested feathered and rose comb based on a range of socio-economic and genetic factors. The research employed data from 60 households and examined variables including population size (POS), changes in population over the last five years (CHA), disease control (DC), economic development (ECO), cultural importance (CUL), and conservation practices (CON). Genetic diversity was assessed using heamoglobin polymorphism. The estimated extinction probabilities for the genotypes calculated based on these factors revealed an overall extinction probability of 0.58 indicating a moderate to high risk of extinction. Frizzle feathered and naked neck chickens had the highest extinction risks (0.78 and 0.73) while shank feathered chicken had the lowest (0.28). Genetic analysis revealed varying levels of genetic distinctness between and among the chicken types, with the naked neck and normal feathered chickens showing the greatest genetic differentiation. These findings underscored the importance of targeted conservation efforts, including improved production systems, disease control, and strategic breeding programmes, to reduce extinction risks and preserve the genetic diversity of these Nigerian chicken-types. This result should be confirmed using advanced nucleic acid-based technique

Regional Integration and Sustainable Development in West Africa: The Role of Governance Quality
(National Institute for Legislative & Democratic studies (NILDS), National Assembly, Abuja, 2026-02-26) Muktar Sabi, Abdul M. Shitu, Yusuf Toyin Yusuf & Lukman S. Adam
Regional integration offers substantial potential for advancement, but West Africa's economic growth and development through cross-border trade remain below optimal levels, impeding progress toward Sustainable Development Goal 17 (SDGs). This study examines the role of governance quality on the effectiveness of regional integration and sustainable development in West Africa from 1996 to 2022. A modified Cobb-Douglas production function, augmented with trade integration and governance quality, was estimated using the Dynamic Panel Model with Interacting Effects (DPMEs) method, specifically the system GMM. Variables such as the adjusted net savings, which served as the proxy for sustainable development, capital stock, number of labour employed, trade integration and index of the six governance quality indicators, which were sourced from the World Bank’s Development Indicators (WDI) and Governance Indicators (WGI), respectively. The findings revealed that governance quality has a positive and long-run significant impact on sustainable development in West Africa. But the relationship was found to be weak due to the regional characteristics. regional integration offers substantial potential for advancement, West Africa's economic growth and development through cross-border trade remain below optimal levels, impeding progress toward Sustainable Development Goals (SDGs).

The findings revealed that governance quality has a positive and insignificant impact on sustainable development (measured by Adjusted Net Saving (ANS)) in the short run, but is significant in the long run, implying that the quality of governance in achieving sustainable development in West Africa is weak. The lag in the number of people employed showed a negative and insignificant impact on sustainable development, suggesting that an increased level of unemployment could deter sustainable development. However, trade integration and the interaction of governance quality with trade integration showed positive and significant impacts, reflecting efficiencies in regional trade practices due to moderate governance quality in the region. The study therefore recommends that strategic economic policy measures like free trade, and governance policies like employment opportunities, and regional cooperation should be adopted to accelerate sustainable development in West Africa.

ANALYSIS OF POLITICAL INSTITUTIONS AND CENTRAL BANK TRANSPARENCY IN SELECTED AFRICAN COUNTRIES
(Department of Economics, University of Ilorin, 2020-06-17) Abdulhakeem A Kilishi, Muktar S Adamu
Studies on central bank transparency focus on effect of central bank transparency rather than causes or determinants of central bank transparency. This paper empirically examined the impact of different measures of political institutions on central bank transparency. A panel data of twenty-two African countries was gathered over a period 2006 to 2018. Driscoll and Kraay method was used to gauged the model. The findings revealed that central bank transparency increases as quality of political institutions improve. The paper recommended that political institutions should be reformed to allow: (i) citizens participation in public decision making, (ii) equal opportunity for all including minority and women in political participation, (iii) restriction on exercise of executive powers, and (iv) adherent to the basic component of rule of law, principle of checks and balances, as well as true separation of power among the arms of government.

Resilience as a Correlate of Learning Outcomes among Adolescents with Hearing Impairment in Ibadan, Nigeria
(International Journal of Academic Information Systems Research (IJAISR), 2026-09-30) Professor Kelechi U LAZARUS, Adedayo ADESOKAN (PhD), Hafsoh Aderonke ASHANKE, Sunday Olubayo AWOLOLA, Abdulazeez Kayode AKOREDE, Ether Ouluwatimileyin OGUNFEYITIMI
Abstract: Adolescents with hearing impairment often record lower academic outcomes than their hearing peers, a pattern sometimes read, unfairly, as evidence that they lack the drive or inner resource needed to succeed in school. This study examined resilience as a psychological correlate of learning outcomes, conceptualised here as academic achievement and social interaction, among adolescents with hearing impairment in Ibadan, Nigeria. Two research purposes were pursued and two null hypotheses were tested. The study was anchored on Vygotsky's Sociocultural Theory and adopted a descriptive research design of the correlational type. A census sample of 30 adolescents with hearing impairment was drawn from two special schools in Ibadan. Data were collected using an Academic Achievement Proforma, the Connor-Davidson Resilience Scale (CD-RISC-10), and a Social Interaction Scale (SIS), whose reliability coefficients were established at 0.76 and 0.72 respectively through test-retest and Cronbach's alpha. Both hypotheses were tested using Pearson Product-Moment Correlation (PPMC) at the 0.05 level of significance. Findings showed no statistically significant relationship between resilience and academic achievement (r(28) = -.063, p = .739) or between resilience and social interaction (r(28) = .143, p = .449). It is concluded that, within this sample, resilience functions largely as an individual coping resource that does not by itself translate into stronger classroom performance or richer peer engagement, a pattern consistent with a sociocultural reading in which learning and social participation depend more on the availability of accessible interactional structures, such as interpreters and trained More Knowledgeable Others, than on internal adaptive capacity alone. The study recommends that schools invest in communication infrastructure and structured peer-interaction programmes rather than relying on resilience-building in isolation to improve outcomes for this population.
