Item Information integration, procurement internal controls, material and purchasing procedure standardization and procurement performance in humanitarian organizations(Journal of Humanitarian Logistics and Supply Chain Management., 2023) Muhwezi, Moses; Mutebi, Henry; Ssekajja Mayanja, Samuel; Tukamuhabwa, Benjamin; Namagembe, Sheila; Kalema, RobertPurpose – Procuring relief products and services is a challenging process for humanitarian organizations (HOs), yet it accounts for approximately 65% of relief operations’ costs (Moshtari et al., 2021). This paper aims to examine how procurement internal controls, materials and purchasing procedure standardization influence information integration and procurement performance. Design/methodology/approach – In this study, partial least square structural equation models and multigroup analysis were used to analyze data collected from 170 HOs. Findings – Procurement internal controls and material and purchasing procedure standardization fully mediate between information integration and procurement performance. Research limitations/implications – The study focuses only on HOs. Since humanitarian procurement projects take place over a period of several years, it is difficult to capture the long-term effects of information integration, procurement internal controls, material and purchasing procedure standardization and procurement performance. In this regard, a longitudinal study could be undertaken, provided that the required resources are available. Practical implications – Procurement managers should implement information integration practices within acceptable procurement internal controls and standardize material and purchasing procedures to boost procurement performance. Originality/value – By integrating information through procurement internal controls and standardizing material and purchasing procedures, procurement performance in a humanitarian setting can be systematically optimized.Item Positive deviance, ecologies of innovation and entrepreneurial networking(World Journal of Entrepreneurship, Management and Sustainable Development, 2019) Ssekajja Mayanja, Samuel; Mapeera Ntayi, Joseph; Munene, John C.; Kagaari, James R.K.; Balunywa, Waswa; Orobia, LauraThe purpose of this paper is to examine the mediating role of ecologies of innovation in the relationship between positive deviance (PD) and entrepreneurial networking among small and medium enterprises (SMEs) in Uganda. Design/methodology/approach – A cross-sectional survey design using quantitative approach was employed in this study. Data were collected with the help of self-administrated questionnaires from 228 SMEs. Systematic sampling technique was used. Multiple regression data were analysed with the help of SPSS software. Findings – The results indicated that ecologies of innovation partially mediate the relationship between PD and entrepreneurial networking. Besides, PD and entrepreneurial networking are significantly related. Research limitations/implications – The data were cross-sectional in nature, thus limiting monitoring changes in resources accessed from social networks by entrepreneurs over time. Practical implications – Managers of SMEs and policy makers should pay more attention to the views of employees with divergent views, ecologies of innovation in creating a conducive environment for creativity and innovation among SMEs. Originality/value – The study of PD, ecologies of innovation and entrepreneurial networking using complexity theory among SMEs in Uganda is a contribution to literature.
