Leadership Styles, School Welfare Measures and Organisational Citizenship Behaviour among Administrative Staff in Private Universities in Oyo State
(Lead City University, 2024-11) Onome Peace AVURAKOGHENE
Private University administrative staff in Oyo State seems to be exhibiting poor organizational citizenship behaviours, resulting in reduced support, job satisfaction, effectiveness, turnover, and reduced innovation. Factors contributing to this include poor organisational justice, work motivation, work-life balance, and poor working conditions among others. However, little research has been conducted on the influence of leadership styles and school welfare measures on organisational citizenship behaviour among administrative staff in private universities of Oyo State. Thus, to bridge this gap this study investigated the influence of these factors on organisational citizenship behaviour among administrative staff in private universities in Oyo State. A descriptive research design was used to guide the study. The population consisted of all 675 administrative staff in private universities in Oyo State. A complete enumeration sampling technique was used in the study. The findings revealed that the level of organisational citizenship behaviour among administrative staff in private universities in Oyo State was high ( x̄=3.23); the most adopted leadership style in private universities in Oyo State was the transformational style; level of school welfare measures was high (x̄=3.14); the combined influence of leadership styles and school welfare measures had a significant influence on organisational citizenship behaviour among administrative staff in private universities in Oyo State (Adj. R2 = 0.991) and (F(2,614) = 32145.714; p < 0.000); among the leadership styles, pace-setting demonstrates the strongest positive influence on organisational citizenship behaviour (β = 0.401, t = 15.325, P < 0.05); study leave does not significantly influence organisational citizenship behaviour (β = -0.003, t = -0.137, p > 0.05). Based on these findings, it was recommended among others that private universities should invest in comprehensive leadership training programmes and prioritise enhancing school welfare measures to encourage organisational citizenship behaviour among administrative staff in private universities in Oyo State.

Training Assessment, Information Communication Technology Use and Senior Secondary School Principals Job Performance in Lagos State
(Lead City University, Ibadan, 2024-12) Olabanke Aduke YUSUF
In recent years, there seems to be a noticeable concern regarding the job performance of principals in public senior secondary schools in Lagos State. This is evident in poor
management practices, reduced parental satisfaction, decreased teacher morale, poor job satisfaction, negative reputation and perception and so on. Factors contributing to these challenges could be inadequate training of school principals, high administrative burden, burnout and stress, among others. Previous studies have highlighted numerous factors causing the aforesaid problems in other states, but work has not been done specifically, addressing this issue within the context of public senior secondary schools in Lagos State. To fill this gap, this study aims to investigate the influence of training assessment and information communication technology use on senior secondary school principals job performance in Lagos State. A descriptive research design of the survey type was used to guide the study. The population consists of all 323 principals in public senior secondary schools in Lagos State. An Intact sampling technique and a self-developed questionnaire (PJPQ) for principals was utilised. The findings revealed that the level of job performance of senior secondary school principals in Lagos State is high( x̄=3.19); the level of training assessment of senior secondary school principals in Lagos State is high( x̄=3.07); the level of ICT use among principals in senior secondary school in Lagos State is high( x̄=3.07); the combined influence of training assessment and ICT use has a significant influence on job performance of senior secondary school principals in Lagos State(Adj. R 2 =0.987) and (F(2,275)=10271.187; p< 0.05); technology integration demonstrates the strongest influence on principals job performance (β=0.640, t=15.919, p< 0.05). Based on these findings, it was recommended among others that schools should invest in ongoing ICT training that keeps principals abreast of emerging technologies and their applications in education.

Nutritional and Sensory Evaluation of Instant Extruded Snack Developed from Blends of Malted (Yellow Maize and White Sorghum), Soybeans, Sweet Potato and Brisket Bones
(Lead City University, Ibadan, 2024-12) Samuel Olusina OWOLABI
This study evaluated the nutritional and sensory properties of instant extruded snacks from a combination of malted yellow maize and white sorghum, soybean, sweet potato, and brisket bones. The maize and sorghum were malted for 30 and 20 hours respectively, while the sweet potatoes, soyabean and brisket bones were dried and converted to flours. Nine flour blends were formulated and subdivided into three segments where Segment A (maize based),ASO BSO: & CSO, Segment B (sorghum based),DSO, ESO , FSO. and Segment C (maize-sorghum based), GSO, HSO, ISO, were used to produce instant extruded snacks using a twin-screw extruder. The proximate and nutritional properties of the extrudes were evaluated, sensory evaluation was conducted using a 9-point hedonic scale, and the results were analyzed using SPSS. The analytical values for the nine samples ranged from 3.10 to 3.20% for moisture content, 1.71 to 2.00% for ash, 10.29 to 10.58% for fiber, 12.80 to 14.52% for crude protein, 3.10 to 3.15% for fat, 66.08 to 68.33% for carbohydrate, and 350.27 to 355.94 kcal for energy. Micronutrient values per 100mg ranged from 260.23 to 275.10mg for calcium, 137.22 to 162.42mg for magnesium, 455.23 to 458.35mg for potassium, 120.00 to 142.45mg for sodium, 370.23 to 403.23mg for potassium, 40.20 to 49.65mg for iron, 2.21 to 3.23mg for zinc, 3.43 to 4.56mg for vitamin A, 3.76 to 4.34mg for vitamin B1, and 0.69 to 0.76mg for vitamin B2. The results showed no significant differences (p>0.05) between samples from the same cereal base, but significant differences (p>0.05) between samples from different cereal bases. Increasing soybeans and malted grains increased the protein and carbohydrate content. Conclusively, maize-based formulations were preferred over sorghum-based. Nutritional, healthy, and acceptable instant snacks for managing malnutrition can be developed from these snacks.

Nutritive Assessment & Acceptability of Bread Fortified with Avocado Seed Powder
(Lead City University, Ibadan, 2024-12)
This research assesses the efficacy of avocado seed powder (ASP) in the fortification of bread. The incorporation of avocado seed powder into bread formulations occurred at 5% and 10% of the weight of flour, alongside fixed ratios of other ingredients (yeast, butter, milk, egg, sugar and water). The fortified dough underwent evaluation for proximate composition, antioxidant activity, and functional properties utilizing standardized chemical methodologies. Furthermore, a sensory evaluation involving 30 participants was performed employing a hedonic scale. Findings indicated that the fortification of bread with ASP significantly elevated its fiber content (P<0.05), concurrently leading to a reduction in protein and fat content (P<0.05) as the levels of ASP increased. The total phenolic content varied from 0.39 ng/kg in the control bread to 2.10 ng/kg in the bread containing 10% ASP. Additionally, avocado seed powder enhanced the antioxidant capacity of the bread, with Diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity increasingzz as from 57.83% in control samples to 62.41% in bread comprising 5% ASP. Functional attributes such as bulk density and water absorption capacity were markedly improved with the incorporation of ASP. Sensory evaluation showed that the inclusion of ASP adversely influenced the appearance of the bread but did not significantly affect flavor or overall acceptability (P>0.05). The study concludes that the addition of avocado seed powder, at levels up to 10%, enhances the nutritional profile of bread without substantially compromising consumer acceptability.

Knowledge and Perception of In-School Adolescents on the Role of Adequate Diet in Non- Communicable Diseases Prevention and Management in Ogun State, Nigeria
(Lead City University, Ibadan, 2024-12) Gbemisola Taiwo OLAPO
Non-communicable diseases (NCDs) have become a significant public health challenge, particularly among adolescents in low- and middle-income countries like Nigeria. Consuming unhealthy food is a significant and modifiable behavioral risk factor for the development of NCDs later in life. To address the global NCD pandemic, which is responsible for 74% of deaths globally and 29% of deaths in Nigeria, nutrition literacy and healthy eating habits, particularly among adolescents and younger age groups must be encouraged. This cross sectional study assessed the knowledge and perception of in-school adolescents (N=480) aged 10-19 years in Ogun State, Nigeria regarding the role of adequate diet in NCDs prevention and management. Using a 23-item assessment scale, 302(63%) respondents demonstrated good knowledge of NCDs (scores ≥70%), 129(27.4%) showed fair knowledge (50-70%), and 46(9.6%) showed poor knowledge (50%). On a 7-item scale assessing knowledge of diet's role
in NCD prevention, 273.6(57%) demonstrated good knowledge (scores ≥70%), 52.8(11%) showed fair knowledge (scores 50-70%), and 153.6(32%) showed poor knowledge (scores <50%). Regarding perceptions, 36% of respondents had a positive perception of the importance of diet in NCD prevention and management, while 64% had a negative perception. Correlation analyses revealed weak but significant positive associations between respondents' age (r=0.045, p=0.004), gender (r=0.016, p=0.029), and residential location (r=0.025, p=0.003) with more positive perceptions. Anthropometric measurements showed that 60.8% of respondents had normal weight, 23.3% were underweight, and 15.9% were overweight and obese. Despite generally demonstrating good knowledge of major NCDs and their dietary link, 43.1% believed NCDs were caused by supernatural powers, 72.1% perceived traditional cultural foods as generally healthy, and 65% viewed consuming a balanced diet as inconvenient and expensive. The findings highlight the need for culturally sensitive nutrition education programs to address knowledge gaps, dispel misconceptions, and promote healthier dietary habits among Nigerian adolescents.
