We succeeded in performing mass spectrometry imaging (MSI) of the localization of capsaicin in crosssections of the Capsicum fruits at a resolution of 250 µm using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF)mass spectrometry. Post source decay of protonated capsaicin ion revealed structural information of the corresponding amide, vanillylamide, and C9 chain fatty acid. MALDI-TOF-MSI confirmed that localization of capsaicin in the placenta is higher than that in the pericarp. In addition, it revealed no localization of capsaicin in seed and the higher localization of capsaicin at placenta surface compared with that in the internal region. A quantitative difference was detected between localizations of capsaicin at placenta, pericarp and seed in the Capsicum fruits. This imaging approach is a promising technique for rapid quality evaluation of general food as well as health food and identification of medicinal capsaicin in plant tissues.
The objective of this research is to clarify, empirically, how business factors influence the overseas expansion of small-to-medium-sized manufacturers (SMMs). With the internationalisation of a business, many SMMs have increased their overseas expansion in recent years. On the one hand, the probability of success for overseas expansion is not necessarily high. Of course, a lot of SMMs have succeeded in overseas expansion and expanded their revenue. On the other hand, however, there are many cases of SMMs failing in and withdrawing from the overseas expansion process. Although the influence of succeeding or failing is great in regard to corporate performance, there is a lack of clarification as to which business factors serve as the basis for SMMs' decision-making. In this paper, research hypotheses are proposed to help measure the influential difference between the following select sources of competitive advantage: (a) external positioning and internal organizational capability; and (b) static perspective and dynamic perspective. Then, the select sources of competitive advantage are typified based on prior research. To verify the hypotheses, a questionnaire was implemented toward SMMs of Japan that expanded their business overseas. As a result, it became clear that the optimal overseas expansion strategies are different according to an SMM's source of competitive advantage. As a contribution, it is expected that the results of this research will support the decision-making of SMMs toward overseas expansion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
