Much of the analysis of economic growth has focused on the study of aggregate output. Here, we deviate from this tradition and look instead at the structure of output embodied in the network connecting countries to the products that they export. We characterize this network using four structural features: the negative relationship between the diversification of a country and the average ubiquit...

Abstract The few existing studies on the relationship between Aid for Trade (AfT) flows and inward foreign direct investment (FDI) tend to report a positive effect of total AfT flows, in particular aid building economic infrastructure, FDI inflows. This article aims complement these works by investigating whether stock depends recipient countries' level export product concentration. Empirical a...

Cyclodextrin glucanotransferases (CGTases) have attracted major interest from industry due to their unique capacity of forming large quantities of cyclic α-(1,4)-linked oligosaccharides (cyclodextrins) from starch. CGTases produce a mixture of cyclodextrins from starch consisting of 6 (α), 7 (β) and 8 (γ) glucose units. In an effort to identify the structural factors contributing to the evoluti...

a vertex irregular total k-labeling of a graph g with vertex set v and edge set e is an assignment of positive integer labels {1, 2, ..., k} to both vertices and edges so that the weights calculated at vertices are distinct. the total vertex irregularity strength of g, denoted by tvs(g)is the minimum value of the largest label k over all such irregular assignment. in this paper, we study the to...

Implementation of Human-centred Design methods in the Fuzzy FrontEnd is not likely to lead to diversification in educational product planning exercises, where time lines are short and executors lack experience. Companies, interested to collaborate with M.Sc. students on strategic design projects, should have realistic ambitions with respect to innovation and value creation. Moreover, diversific...

Currently used decision support systems allow decision-makers to evaluate the product performance, including a net present value analysis, in order enable them make regarding whether or not carry out new development project. However, these solutions are inadequate provide simulations for verifying possibility of reducing total cost through changes design phase. The proposed approach provides fr...
