This study examined the effect of port infrastructural development on cargo delivery efficiency at Tin Can Island Port, Nigeria, using a quantitative survey design based on primary data collected with a structured fourpoint Likertscale questionnaire. Andrew Fisher’s formula produced an initial sample size of 384.16, which, after finite population correction, was adjusted to approximately 278 respondents, ensuring adequate power for statistical analysis and feasible field administration. The regression results at a 95 percent confidence level show a strong relationship between infrastructural development and cargo delivery efficiency, with correlation coefficients up to R = 0.852, coefficients of determination R2 = 0.726 and adjusted R2 = 0.722. The key infrastructure predictors; berth/equipping facilities, cargohandling equipment, storage infrastructure and power/ICT systems, exhibiting positive, statistically significant effects at p < 0.001. Berth/equipping facilities consistently emerged as the most influential predictor, followed by cargohandling equipment, power/ICT and storage infrastructure, indicating that physical and mechanical constraints are critical drivers of efficiency outcomes. The study concludes that comprehensive infrastructural upgrading is an evidencebased core strategy for improving cargo throughput, vessel turnaround time and overall delivery performance at Tin Can Island Port, but that residual variance points to the need for complementary operational and regulatory reforms. It recommends phased berth rehabilitation and equipment modernization, investments in reliable power and integrated ICT platforms, and process reengineering of clearance, labour practices and hinterland connectivity to secure sustainable, systemwide efficiency gains.

This study examined the relationship between leadership implementation and business success in real estate firms in the South-South, Nigeria. The study was guided by four research questions and four research hypotheses. The study adopted a cross-sectional correlational survey design with a population of 220 real estate firms in the South-South, Nigeria. A sample size of 140 was drawn using the Krejcie & Morgan table on sample size determination. 140 copies of questionnaires were administered to respondents, out of which 131, representing 93%, were found valid for the analysis. All items on the questionnaire had a Cronbach's alpha threshold of 0.70 and above in the reliability test. The research questions were answered and the hypotheses tested using Pearson Product Moment Correlation statistics and analyzed using the Statistical Package for the Social Sciences. The result of the data analyzed revealed that there is a positive relationship between leadership implementation and business success in real estate firms in the South-South, Nigeria. Based on the findings, it was recommended that managers of real estate firms should foster a culture of effective leadership that supports strategy implementation. This includes providing training and development opportunities to enhance employee skills and knowledge, recognizing and rewarding employees who demonstrate desired behaviours, and encouraging open communication and feedback. 

This paper examined the relationship of principals’ innovative practices and the instructional effectiveness of tutors in secondary schools in Bayelsa State. The research was driven by the need to understand how modern leadership approaches, specifically reward and recognition, affect teaching outcomes in a dynamic educational landscape. A descriptive survey design was adopted, and a structured questionnaire was administered to a sample of 364 who were randomly selected from different schools across the state using random sampling techniques. The analysis was done using mean and standard deviation and Pearson Product Moment Correlation (PPMC). Findings revealed that all two innovative practices investigated had a significant positive correlation with instructional effectiveness. Specifically, principals’ reward practices motivated teachers, increased their engagement, and improved classroom delivery. Recognition boosted teacher morale and encouraged higher commitment. The paper suggested that the Ministry of Education adopt policy reforms that promote reward systems and recognition programmes in schools. It also emphasised the need for training principals in distributed leadership to foster delegation and collaboration.

This study examined the relationship between sustainability marketing practices and the consumption patterns of non-alcoholic beverages in Rivers State, Nigeria. Specifically, it investigated how green packaging, consumer education, and energy efficiency relate with consumer satisfaction and repeat patronage. Anchored on stakeholder theory, the study adopted a correlational research design and employed structured questionnaires to collect data from a sample of 120 respondents across selected local government areas in Rivers State. The data collected were analyzed using Pearson Product Moment Correlation (PPMC) to test six hypotheses. Findings revealed a significant positive relationship between green packaging and both consumer satisfaction and repeat patronage, indicating that environmentally friendly packaging influences consumers’ perception of quality and brand trust. Similarly, the study found a significant relationship between consumer education and consumer satisfaction, as well as repeat patronage. This suggests that when consumers are informed about a company's sustainable practices, they are more likely to support the brand consistently. Additionally, energy efficiency was found to have a significant relationship with consumer satisfaction and repeat patronage, emphasizing the growing consumer awareness of and appreciation for energy-conscious production processes. The study concludes that integrating sustainability into marketing practices is not only ethically necessary but also strategically beneficial for long-term brand success in the non-alcoholic beverage sector. It recommends that beverage companies should prioritize biodegradable, recyclable, or reusable packaging materials to appeal to environmentally conscious consumers and enhance satisfaction and loyalty. The implications of this study extend to policy makers, marketers, and environmental advocates, suggesting that organizations in the non-alcoholic beverage industry must recognize sustainability not merely as compliance, but as a value-added strategy that can drive competitive advantage and consumer loyalty.

This study examined marine navigational infrastructure and safety standard compliance in Nigerian seaports, with a focus on Apapa Port Complex. Specifically, it assessed the effects of navigational equipment availability, radar and communication functionality, GPS/electronic chart use, maintenance of aids to navigation, and staff competence on accident prevention and compliance with port safety regulations. The study was guided by two hypotheses and adopted a quantitative survey design. Primary data were collected through a structured questionnaire administered to 360 personnel and stakeholders involved in marine navigation, vessel traffic management, safety regulation, and navigational support services at Apapa Port Complex, using both paper-based and Google Forms instruments. Secondary data were obtained from relevant literature and port-related materials. The data were analysed with multiple linear regression at the 0.05 significance level. Findings showed that the combined predictors explained 74.6% of the variance in accident prevention and 49.8% of the variance in compliance with port safety regulations. The ANOVA results confirmed that both regression models were statistically significant, while the coefficient estimates showed that all predictors positively influenced the two dependent variables. Maintenance of navigational aids and staff competence emerged as the strongest predictors of accident prevention, while navigational equipment availability, GPS/electronic chart use, and aid maintenance were key determinants of regulatory compliance. The study concludes that marine navigational infrastructure and human competence are critical to safer vessel operations and stronger adherence to safety standards in Nigerian seaports. It recommends improved equipment provision, regular maintenance of navigational aids, continuous staff training, upgraded communication systems, and stricter enforcement of port safety regulations to enhance operational safety and reduce accidents.
