Innovation in Nigerian SMEs: types and impact

This paper seeks to explore the types of innovation that are predominant in SMEs in developing countries and to investigate the impact of these innovations on different dimensions of firm performance based on an industry-wide innovation survey carried out in Nigeria in 2007. Although innovation is important for superior firm performance, our result found that the type of innovation that SMEs pursue is not a critical consideration in their performance. While there was no difference found in the focus of SMEs on either of product or process innovations, evidence showed that SMEs would focus more on incremental product and process innovations. Incremental innovation was found to be very important for Nigerian SMEs and a significant predictor of product quality and not of revenue. The authors conclude that SMEs chooses to pursue such innovations that most fit their strategies and available resources. Such level of innovation affords Nigerian SMEs to more extensively exploit the domestic market but cannot support extensive new product development required to enter export markets.innovation; small and medium enterprises; Nigeria; impact

What Drives Innovation?: Inferences from an Industry-Wide Survey in Nigeria

This chapter seeks to make some contributions to the literature on firm-level innovation in Africa by attempting to identify the significant factors that explain the capability of firms in Nigeria to innovate using the results of an industry-wide study. We focused on the product and process innovation activities of firms between 2003 and 2006 and found differences in the factors that drive them at the firm level. Our results further show that interactions matter more than most innovation-related variables and that the most important actors that influence a firm’s innovation efforts are its customers and suppliers. We conclude that product and process innovations are not mutually exclusive and that a major key to successful innovation is how and with whom a firm collaborates. The implication of this for firms and policy makers is that an effectively wired innovation system where all stakeholders are active is critical for firm-level innovation capability.innovation; drivers; manufacturing industry; Nigeria; determinants

Herb–Drug Interactions with St John’s Wort (Hypericum perforatum): an Update on Clinical Observations

St John’s wort (SJW) extracts, prepared from the aerial parts of Hypericum perforatum, contain numerous pharmacologically active ingredients, including naphthodianthrones (e.g., hypericin and its derivatives), phloroglucinols derivatives (e.g., hyperforin, which inhibits the reuptake of a number of neurotransmitters, including serotonin), and flavonoids. Such extracts are widely used for the treatment of mild-to-moderate depression. As a monotherapy, SJW has an encouraging safety profile. However, relevant and, in some case, life-threatening interactions have been reported, particularly with drugs which are substrate of cytochrome P450 and/or P-glycoprotein. Well-documented SJW interactions include (1) reduced blood cyclosporin concentration, as suggested by multiple case reports as well as by clinical trials, (2) serotonin syndrome or lethargy when SJW was given with serotonin reuptake inhibitors, (3) unwanted pregnancies in women while using oral contraceptives and SJW, and (4) reduced plasma drug concentration of antiretroviral (e.g., indinavir, nevirapine) and anticancer (i.e., irinotecan, imatinib) drugs. Hyperforin, which is believed to contribute to the antidepressant action of St John’s wort, is also strongly suspected to be responsible of most of the described interactions
