To date, most research on outsourcing is modeled from the client's perspective. In this paper, we approach the Beijing Organizing Committee for the Games of the XXIX Olympiad (BOCOG) outsourcing contracts from the vendors' perspective. Since a vendor always has the option to accept or not accept...

The authors propose a topological analysis of large urban street networks based on a computational and functional graph representation. This representation gives a functional view in which vertices represent named streets and edges represent street intersections. A range of graph measures,...

This paper introduces a novel approach to study the effects of common shocks on panel data models with endogenous explanatory variables when the cross section dimension (N) is large and the time series dimension (T) is fixed: this relies on conditional strong laws of large numbers and...

This paper introduces a new concept of least community that is as homogeneous as a random graph, and develops a new community detection algorithm from the perspective of homogeneity or heterogeneity. Based on this concept, we adopt head/tail breaks–a newly developed classification scheme for...

This paper aims to measure the efficiency of urban street networks (a kind of complex networks) from the perspective of the multidimensional chain of connectivity (or flow). More specifically, we define two quantities: flow dimension and flow capacity, to characterize structures of urban street...

This paper presents a novel photovoltaic-Trombe wall (PV-TW). Based on the actual measured weather data in Hefei, a detailed simulation model for PV-TW is presented. The simulation results show that as the coverage ratio increases, the electrical yield and the total efficiency of PV-TW...

Many complex networks demonstrate a phenomenon of striking degree correlations: that is, a node tends to link to other nodes with similar (or dissimilar) degrees. From the perspective of degree correlations, in this paper we attempt to characterize topological structures of urban street...
