Although the literature documents the direct effects of managerial ties on firm performance, the empirical results are divergent and inconclusive. To explain these disparities, this study (1) develops and tests a model that establishes the role of external resource acquisition as a salient...

Without the agricultural standardization, there would be no agricultural modernization. Through many years of effort, the building of agricultural standardization system in Zhejiang Province has made significant achievements, effectively giving play to the technology supporting role of...

Drought is an extreme event in hydrologic cycle. The occurrences of drought events usually feature determinacy and randomness. With the increasing impact of climate change and anthropogenic activities, drought happens in more areas with higher frequency, and now it threatens the water and...

Based on the daily precipitation data of 38 weather stations in the Huai River Basin from 1961 to 2010, this study used SPI index, P-III curve to determine the flood/drought years, under what situations for droughts and floods easily happen, and to analyze the evolution law of flood and drought...

We study the operations scheduling problem with delivery deadlines in a three-stage supply chain process consisting of (1) heterogeneous suppliers, (2) capacitated processing centres (PCs), and (3) a network of business customers. The suppliers make and ship semi-finished products to the PCs...

Purpose – Calibrating kinematic parameters is one of the efficient ways to improve the robot's positioning accuracy. A method based on the product-of-exponential (POE) formula to calibrate the kinematic parameters of serial industrial robots is proposed. The paper aims to discuss these issues....

We consider the problem of operations scheduling for a capacitated multi-echelon shipping network with delivery deadlines. Over the network, semi-finished goods are shipped from origins to many demand points through a capacitated network consisting of shipping links and capacitated processing...

Spectral clustering uses eigenvectors of the Laplacian of the similarity matrix. It is convenient to solve binary clustering problems. When applied to multi-way clustering, either the binary spectral clustering is recursively applied or an embedding to spectral space is done and some other...
