A framework to assess the factors affecting success or failure of the implementation of government-supported regional e-marketplaces for SMEs

Abstract: Regional electronic marketplaces (REMs) have been used to promote e-commerce uptake by small and medium enterprises (SMEs). However, the community and regional economic development motives underpinning REM creation can cause complexities. While REM development and management can be informed by existing theoretical frameworks, there is no comprehensive framework that can be used to examine the factors affecting the success or failure of government-supported SME-REMs. The objective of this paper is to construct such a framework that can be used to examine these factors. The literature on e-marketplaces and IT/IS/e-commerce adoption by SMEs is examined to determine the appropriateness of existing theoretical frameworks, the key constructs of which are synthesised to form an integrated theoretical framework. The value of the framework is confirmed by content analysis of published case studies and empirical results from in-depth case studies of two SME-REMs. The most significant factors affecting success or failure of government-supported SME-REMs are as follows: SME-owner innovativeness; REM ownership structure and governance that engender trust and build critical mass by including SMEs in REM development and management; matching REM focus and structure with regional profile by leveraging community ties and existing business relationships; adopting a staged approach to REM development; and ensuring REM benefits are understood by SMEs.

A Meta-Analysis of Seaweed Impacts on Seagrasses: Generalities and Knowledge Gaps

Abstract: Seagrasses are important habitat-formers and ecosystem engineers that are under threat from bloom-forming seaweeds. These seaweeds have been suggested to outcompete the seagrasses, particularly when facilitated by eutrophication, causing regime shifts where green meadows and clear waters are replaced with unstable sediments, turbid waters, hypoxia, and poor habitat conditions for fishes and invertebrates. Understanding the situations under which seaweeds impact seagrasses on local patch scales can help proactive management and prevent losses at greater scales. Here, we provide a quantitative review of available published manipulative experiments (all conducted at the patch-scale), to test which attributes of seaweeds and seagrasses (e.g., their abundances, sizes, morphology, taxonomy, attachment type, or origin) influence impacts. Weighted and unweighted meta-analyses (Hedges d metric) of 59 experiments showed generally high variability in attribute-impact relationships. Our main significant findings were that (a) abundant seaweeds had stronger negative impacts on seagrasses than sparse seaweeds, (b) unattached and epiphytic seaweeds had stronger impacts than ‘rooted’ seaweeds, and (c) small seagrass species were more susceptible than larger species. Findings (a) and (c) were rather intuitive. It was more surprising that ‘rooted’ seaweeds had comparatively small impacts, particularly given that this category included the infamous invasive Caulerpa species. This result may reflect that seaweed biomass and/or shading and metabolic by-products like anoxia and sulphides could be lower for rooted seaweeds. In conclusion, our results represent simple and robust first-order generalities about seaweed impacts on seagrasses. This review also documented a limited number of primary studies. We therefore identified major knowledge gaps that need to be addressed before general predictive models on seaweed-seagrass interactions can be build, in order to effectively protect seagrass habitats from detrimental competition from seaweeds.
