Information Systems and Operational Efficiency of Maritime Firms in Port Harcourt.
Abstract
The study examined the relationship between information systems and operational efficiency of maritime firms’ in Port Harcourt, Rivers State. Three research questions and three research hypotheses were formulated to address the specific objectives of this study. The RBV theory was adopted in this study and also quantitative research design using a correlational method of investigation. The population consists of 16 maritime firms in Port Harcourt. Census sampling was applied with focus on managers. Four managers per firm were sampled; a total of 64 managers were sampled. The reliability of the instrument was determined using Cronbach alpha test and it stood at 0.88 higher than the benchmark of 0.7. The data collected for this study were analyzed through descriptive and inferential statistics. The Spearman Rank-Order Correlation Technique was employed to test the various hypotheses formulated. The result of the analysis revealed that the information system is significantly and positively related to the operational efficiency of maritime firms’ in Port Harcourt, Rivers State. The empirical results of this study confirmed this as a positive and significant relationship was found between processing transaction systems and operational efficiency of maritime firms, and between electronic data interchange and operational efficiency of maritime firms. Based on these findings, it was concluded that the information system with its dimension of processing transaction system and electronic data interchange will improve operational efficiency of maritime firms in Port Harcourt. This study recommends that maritime firms should leverage on information systems as this would ensure reduction in cost and improve operational efficiency; they should use processing transaction system in order to facilitate the recording, tracking, and management of business transactions within the organization and the port, and they should adopt electronic data interchange for processing of documents and timely delivery of same.

Overview of Agglomerative Hierarchical Clustering Methods.
Abstract
Agglomerative hierarchical clustering methods are the most popular type of hierarchical clustering used to group objects in clusters based on their similarity. The methods uses a bottom-up approach and it starts clustering by treating the individual data points as a single cluster, then it is merged continuously based on similarity until it forms one big cluster containing all objects. In this paper, we reviewed eight agglomerative hierarchical clustering methods namely: single linkage method, complete linkage method, average linkage method, weighted group average method, centroid method, median method, Ward’s method and the flexible beta method; we also discussed measures of similarity and dissimilarity using quantitative data as our reference point.

To generate data for the study, sixty three (63) copies of questionnaire were given to the twenty one registered Banks in the frame of three (3) copies per bank. The questionnaire was structured in a four (4) point likert scale. The data collected through the questionnaire were analyzed using Pearson Product Moment Correlation. From the bivariate analysis carried, it was discovered that electronic marketing strategies showed a significant relationship with customer satisfaction of commercial banks in Port Harcourt, Rivers State. It was revealed that content marketing showed a very strong and significant relationship with customer retention of commercial banks in Port Harcourt, Rivers State. Also, e-mail marketing showed moderate and significant relationship with customer retention of commercial banks in Port Harcourt, Rivers State.

Using QR Code and a Smartphone to Provide University of Cross River State (UNICROSS) Certificate Authentication.
Abstract
In the modern world, people frequently fabricate their credentials in order to secure a job or to show up where and when it is necessary. Verification is the most effective approach to identify those fraudulent certificates. Despite this, the paper verification method requires a drawn-out and time-consuming process to handle certificate verification because the certificates must be returned to the institutions who awarded them. As a result, the certificates either fail to pass verification or are delayed by the lengthy process. As a result, a certificate verification method using QR codes is developed in this study for quick verification of University of Cross River State (UNICROSS) certificate genuineness. A Smartphone and 3D Printed QR Code were employed for the enhancement of UNICROSS certificate mobile authentication services. ScanTrust anti-counterfeiting services was used to secured and hosting of the encrypted information. Results shows that our framework is effective for creating mobile authentication services with high user satisfaction rate and having reasonably low computing requirement.

Nollywood Movie Sequences Summarization Dataset for Machine Learning Applications
Abstract
Summarization in recent time has become one of most exploited area of natural language processing task, due to significant increase in data volume which is more than terabytes and petabytes. In this article, we present a custom dataset for Nollywood movie sequences, an extensive collection of 13 Nollywood movies representing various genres, including drama, comedy, action. This custom dataset was impendent into pre-train benchmark dataset TVSum following the same file format, frame size and others in order to suit our purpose. Fast Forward Moving Picture Expert Group (FFMPEG) were used for video encoding during pre-processing and final skimming. The proposed framework is effective for creating movie summary with high user satisfaction rate and having reasonably low computing requirement.
