Utilization of periwinkle and palm kernel shells in load-bearing ecofriendly interlocking concrete paver
(Frontier in Built Environment, 2025-01-10) Olofinnade, Olofinnade; Awoyera, Paul; Edemirukewa, Kelvin; Ogundipe, Kunle
In recent times, increasing demand for raw aggregate has emphasized the need for construction industry to adopt sustainable practices by exploring alternative materials, such as agro-waste, to address resource depletion and reduce environmental pollution., This current study investigated the suitability of combining discarded periwinkle shell (PWKS) and palm kernel shell (PMKS) at low-replacement volumes to partially substitute granite in ecofriendly loadbearing cement-based interlocking paver units for use on medium-duty traffic roads. 108 paver samples were produced, targeting a 28-day strength of 30 MPa, using a mix proportion of 1:1:2 (cement: sand: granite) and water-cement ratio of 0.50. Physical and chemical compositions of materials are examined, while the produced paver samples were tested for their water absorption, compressive and split-tensile strengths properties. The influence of curing (immersion and open air) on the strength development was evaluated. Findings showed that the shells recorded low physical properties but increased water intake tendency. A gradual decrease in the strength performances of the pavers was observed as the amount of PWKS and PMKS increases in the mixes. The water absorption tendency increases with increasing PMKS and PWKS levels. Pavers cured by complete immersion in water recorded good strength and achieved the 30 MPa compared to open air cured pavers. This study recommends load-bearing pavers of up to 30 MPa can be made by combining PMKS and PWKS at a lowreplacement level of 5% deployed for medium-traffic roads, but with adequate curing technique. Outcomes showed the viability of incorporating periwinkle and palm kernel shells as aggregate in making standard paver units of adequate strength and resistance to water to promote sustainable construction practices.

STRATEGIC STAKEHOLDER ENGAGEMENT ON ORGANISATIONAL PERFORMANCE: A STUDY OF SELECTED NON-GOVERNMENTAL ORGANISATIONS IN SOUTH-WEST, NIGERIA
(Covenant University, Ota, 2026-06) AYANLEYE, OMOTOYOSI GOODNESS; Covenant University, Dissertation
The study investigated the relationship between stakeholder involvement and performance of selected non-governmental organisations (NGOs) in South-West Nigeria. The study was driven by funding instability, insufficient stakeholder coordination, inefficient use of resources, and stakeholder dissatisfaction. A quantitative correlational research design was used with 335 staff/volunteers from the selected NGOs in Ogun and Lagos States, who were selected using questionnaires. Descriptive statistics and Partial Least Squares Structural Equation Modelling (PLS-SEM) were used to analyse the data in the present study. The results indicated that the strategic identification, analysis, influence, and engagement of stakeholders had a significant and positive effect on the organisation's performance. Stakeholder analysis contributed to a more effective programme and, in particular, to stakeholder satisfaction. The study found that strategic stakeholder engagement is an essential factor in the performance of NGO workers and could lead to greater sustainability, efficiency, programme impact, and trust in the NGO. It suggests that stakeholder mapping, feedback and inclusive engagement practices need to be improved to boost organisational performance.

CONTRASTIVE ANALYSIS OF MORPHOLOGICAL PROCESSES IN ENGLISH AND HAUSA: A STUDY OF PSALM 91
(Covenant University, Ota, 2026-08) ACHI, SALOME HOSEA; Covenant University, Dissertation
Morphology, being the study of word structure and formation, plays a central role in understanding how languages encode grammatical and lexical meaning. To this end, meaning exist at various levels of language stud (Edet, 2021; Korochkina & Rastle, 2025). However, significant typological differences exist between English, a largely analytic language, and Hausa, a synthetic and morphologically rich language. These differences become particularly evident in translated religious texts, where equivalent meanings are expressed through structurally divergent morphological systems. This study therefore investigated the contrastive morphological processes in English and Hausa languages using Psalm 91 as a parallel corpus. The aim of this study was to conduct a contrastive analysis of morphological processes in Psalm 91 using King James English and Littafi Mai Sarki Hausa versions through the theoretical framework of Item-and-Arrangement (henceforth IA) and Word-and-Paradigm (henceforth WP) theories to account for the observed linguistic patterns. The specific objectives were to: identify and analyse morphological processes in the English version of Psalm 91; examine morphological structures in the Hausa translation of Psalm 91; compare the morphological systems of both languages; apply Word and Paradigm Theory in analysing morphological patterns; utilise Item-and-Arrangement Theory for morphemic segmentation. As such, the study employed a qualitative descriptive research design and purposive sampling to select Psalm 91 as a parallel bilingual text. Data were collected through systematic extraction of lexical items and analysed using morphological segmentation and contrastive comparison. Findings revealed that English morphology is predominantly analytic, with limited inflection and productive derivation, while Hausa exhibits a richer, more systematic morphological structure characterised by extensive affixation, possessive marking, and paradigmatic verb systems. The study further showed that Item-and-Arrangement Theory is more suitable for English morphological segmentation, whereas Word-and-Paradigm Theory gave a better explanation of Hausa morphological relationships. The study contributes to the domain of morphology by clarifying English–Hausa morphological distinctions in the Biblical text. It also validates the complementary application of IA and WP theories, and informs linguistic analysis, translation, and language pedagogy.

TALENT MANAGEMENT ON EMPLOYEE BEHAVIOURAL OUTCOME: A STUDY ON COVENANT UNIVERSITY, OTA OGUN STATE
(Covenant University, Ota, 2026-06) AKINTAYO, Christianah Toluwalope; Covenant University, Dissertation
Talent management has emerged as a strategic human resource management practice for enhancing employee behavioural outcomes and sustaining organisational performance, particularly in higher educational institutions. This study examined the effect of talent management on employee behavioural outcomes among academic staff of Covenant University, Ota, Ogun State, Nigeria. Specifically, the study investigates the influence of talent attraction on turnover retention, the effect of talent identification on innovative work behaviour, the role of talent development on job performance, and the influence of succession planning on employee engagement. The study adopted a positivist research philosophy and a quantitative cross-sectional explanatory survey design. Data were collected from 280 academic staff using a structured questionnaire. The data were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM) with SmartPLS to test the proposed hypotheses and determine the structural relationships among the study variables. The findings revealed that talent attraction had a significant positive effect on turnover retention, talent identification significantly enhanced innovative work behaviour, talent development positively influenced job performance, and succession planning exerted the strongest positive effect on employee engagement. Overall, the study established that effective talent management practices significantly improve employee behavioural outcomes among academic staff. The findings further demonstrate that organisations that strategically invest in attracting, identifying, developing, and retaining talented employees are more likely to achieve improved employee commitment, innovation, performance, and retention. The study concludes that talent management is a critical strategic mechanism for strengthening employee behavioural outcomes and enhancing institutional effectiveness in higher education. It recommends that university management should strengthen talent attraction strategies, implement transparent talent identification systems, invest continuously in staff development programmes, and institutionalise succession planning policies to sustain employee engagement and organisational competitiveness. The study contributes to the growing body of knowledge on talent management by providing empirical evidence from a Nigerian private university and offers practical implications for human resource practitioners, policymakers seeking to improve workforce performance through integrated talent management practices
