Principal Component Analysis of Crime Data in Gwagwalada Area Command, Abuja from 1995 – 2014 (Published)

This paper analyses Abuja crime data which consists of the averages of twenty major crimes reported to the police for the period 1995 – 2014. Correlation analysis and principal component analysis (PCA) were employed to explain the correlation between the crimes and to determine the distribution of the crimes over the three Area Councils under the Gwagwalada Area Command. The result has shown a significant correlation between robbery and rape, grievous hurt and wound (GHW), theft, assault, murder and unlawful escape. Gwagwalada Area Council has the overall crime rate in the Area Command. Rape is more prevalence in Kwali Area Council while unlawful possession and escape is more prevalence in Kuje Area Council Area. The PCA has suggested retaining four components that explain about 94.32 percent of the total variability of the data set.

SUPPLY CHAIN MANAGER COMPETENCIES AND THEIR IMPACT ON SUPPLY CHAIN INTEGRATION (Published)

The level of supply chain professionals’ competencies is a crucial factor to enhance a firm’s competitiveness. Given the limited interdisciplinary study of supply chain management and human resource management, we provide insights of how supply chain manager competencies can impact the supply chain integration of a firm. Starting by developing a list of competencies, using principle component analysis, we achieve two key competencies; namely Technical Knowledge and Application and Traits and Management Skills. Subsequently, we apply multivariate regression to reveal how the two groups of competencies and a supply chain manager’s roles and responsibilities impact differently each dimension of supply chain integration; namely internal integration, supplier integration and customer integration. At a significance level of 0.05, interpretation of regression coefficients reveals that Technical Knowledge and Application impacts internal and customer integration while Traits and Management Skills impacts internal integration. A supply chain manager’s roles and responsibilities impact only internal integration. The findings enable concerned parties to implement actions to enrich supply chain managers of today and in the future.
